Popular retailer Newegg.com has listed the OEM prices for Windows 7, which will be offered at less than half what Microsoft will charge for a retail copy. Newegg hasn't listed any prerequisites for buying the OEM version, such as the purchase of any additional hardware. Past OEM copies have prevented users from taking advantage of Microsoft's support options, however, and the packaging and instructions are usually minimal. For those willing to forgo the additional perks, however, the price may be worth it. Microsoft pursued a similar strategy with Windows Vista, charging "system builders," or anyone building a PC, about half of what it asked retail buyers to pay. Of course, that's nothing compared to the huge preorder discounts that Microsoft offered in September, when it offered a preordered copy for as little as $29.99. According to a Newegg product page, a full 32-bit or 64-bit version of Windows 7 Home Premium will cost $109.99; with a $10 preorder discount that expires Oct. 20, Newegg will lower the price to $99.99. Normally, the upgrade price of Windows 7 Home Premium would be $119.99, and the full retail cost is $199.99. The 64-bit version of Windows 7 Professional OEM will be priced at $139.99; for this version, Newegg will only offer a $5 discount, bringing the price down to $134.99. At retail, the upgrade and full versions of Windows 7 Professional would normally cost $199.99 and $299.99, respectively. The OEM, 64-bit version of Windows 7 Ultimate, meanwhile, will be priced at $174.99. Newegg again will offer a discount of $15, good through Oct. 20, and bringing the price down to $174.99. Normally, the upgrade and full versions would cost $219.99 and $319.99 at retail. A three-pack of Windows 7 Home Premium OEM will cost $309.99, while a three-pack of Windows 7 Ultimate OEM will cost $549.99. Newegg did not advertise a price for the three-pack version of Windows 7 Professional OEM. Windows 7 ships to retailers on Oct. 22. While reports have circulated that Windows 7 may chip early, Microsoft said that users will probably receive Windows 7 when retailers do.

Yes this report says tha Indians Love Google, Gmail, Orkut, Google Maps, YouTube and Blogger. I'm absolutely addicted to Google products and also everyone uses Gmail as their default client, Google Maps is the default mapping engine for us and let’s not even get into the realms of actual search and video-sharing. We all know who dominates there!
So it doesn’t come as a huge surprise to us when ComScore says that Google and its product constitute an amazing 28.9 per cent of the share of total time that Indians spend online. Apparently, of the total 21,799 minutes that Indians (aged over 15) spent on the Internet (at work or home) in July 2009, 6,294 of those were used on navigating Google sites.
Google accounted for 88.4 per cent of all searches conducted, and had commanding share of time spent in social networking with Orkut (68.2 per cent), maps with Google Maps (63.9 per cent) and multimedia with YouTube (82.8 per cent). It also commanded slightly less than half of all time spent in the blogs category with Blogger (47.6 per cent) and email with Gmail (46.8 per cent).
The one disappointment for Google would be the fact that its photo-sharing service Picasa has simply not taken off in India, with it accounting for a mere 16.2 per cent.
Out of all the statistics, the only one which caught us off guard was how dominant Orkut was. We had no doubt that it would be the market leader, but the amount of share it has is staggering, considering how few people we know who prefer it to Facebook now.
Apart from India, only Brazil shares such high Google usage, with it topping the list at 29.8 per cent of all Internet usage in that country.
So why is Google so popular in these two emerging economies? ComScore has a possible explanation.
“As it turns out, there are interesting similarities between Brazil and India as emerging Internet markets,” Alex Banks, managing director of comScore Latin America. “Google’s prevalence in these markets can perhaps best be explained by the fact that the time at which these markets really began to develop and flourish was around the same time that Google was becoming a major player in the search landscape. As a result, Google became the dominant Internet brand in these markets and its success appears to have bled from search into other areas of the Web like social networking.”
You've remember that the 120GB xpPhone was announced by a Chinese company In Technology Group in June 2009. The specialty of this phone is that, it has Windows XP as its OS so 1st of its kind. Forget Windows Mobile now enjoy Windows XP !! Earlier it was said that it will come with a 120GB HDD but now it will also be available in 30, 60 and 80GB variants along with 120GB variant.
The company ITG has started taking pre-orders for the xpPhone with choice of AT&T, Orange, or Vodafone. The phone runs on a AMD Super Mobile CPU, which has specifically designed and customized for this brick. You can go to ITG's English website here for more information about the xpPhone pre-order. Check out the specs of the xpPhone below. Very dim chances of this phone making it to the Indian shores. But it will be a good competitor for the recently release Nokia N900.
In preparation for its global launch, China's In Technology Group (ITG) has just launched a redesigned English website and is now accepting unpriced preorders for the Computex-revealed xpPhone. Trumpeted by the company as the "world's first mobile phone that runs Windows XP," the AMD-powered slider hasn't undergone any notable changes—cosmetically or otherwise—since it was last seen, so all the specs you've previously committed to memory are still intact.
That means the xpPhone is still all about what you see below:
Quite honestly, we are as sick of talking about the advent of 3G in India as you probably are of reading about it. It’s a technology that has been around for the longest time and the country is simply too late in adopting it, as other nations are set to go in for superior wireless Internet advances, with the most prominent being 4G.
So when we came across this news from Live Mint that Motorola India is looking to test their 4G capacities, it stoked the very cockles of our dispassionate and cynical hearts.
For the uninitiated, 4G is – quite obviously – the fourth generation of cellular wireless technologies after 3G and 2G, that would eventually be capable of speeds of at least 100 Mbps. A number of factors make 4G formidable, such as better integration with IPv6, more spectrum efficiency, etc. 4G comprises several wireless technologies, two of which are currently rivaling for top billing: WiMAX and Long-Term Evolution (LTE). LTE is further bifurcated into two halves: 3GPP (current) and Advanced LTE (future).
It is this 3GPP LTE that Motorola India is looking to test. The company, which has tested LTE, is all set to start trial services of 4G that can offer 70Mbps download speeds on a mobile phone by the end of this year.
The company is likely to approach the Department of Telecom (DoT) for trial spectrum, said Subhendu Mohanty, a senior executive with Networks Mobility Business, Motorola India.
Asked whether Motorola is talking to operators, Mohanty said, “We would like to have trial with the players but the technology can also be tested on our own systems.”
As Live Mint points out, this development may discourage carriers from opting for 3G in the upcoming spectrum auction. But we would place all our money on the auction going off smoothly and India suffering from catch-up syndrome for a few more years to come.
We use compressed data every day, whether it be music files (MP3), images (JPEG), video (MPEG-4) or mass-archive storage (ZIP). It is fascinating to watch a large amount of disk space get scrunched into a handy, tiny file. But how does this process of squeezing work?
In this three-part article, we will take you through some of the basics of data compression.
Part 1: Information:
How do we define information? How do we quantify the amount of information that any piece of data contains? In computers, we measure information in bits and bytes (or more accurately now Megabytes and gigabytes).
While this is surely a good way to ascertain the amount of space the data will take to store in a binary format, it lacks to quantify the real worth of the data. Your 100-page project document will probably take less space than a 2-minute commercial. This does nothing to validate the importance of the data.
When we deal with data outside of computers, we tend to look at it in a different way. We might consider it worthy to remember each and every detail of our project and might fail miserably, but we will be able to easily remember the commercial, no matter how little it means to you! While this might seem like an unimportant factor while considering data compression, it becomes quite important while dealing with data such as audio, video, and images.
Like all things, information can be relative, information for me, may be nothing for you. Taking a common example, news of your failing in Mathematics may be no news for you, but it might shock you that you failed in Geography. Which has more information here?
Redundancy
Consider a situation where you get a call from your employee every day that they will be late for work. The call gives you no new information; you already expect to get a call every day around the same time with the same message. However if on a particular day, you get a call saying that they will be on time, the information will suddenly have more meaning. You can see then that in case there is no NEW information, in case there is redundancy, there is a better and more efficient way exchange the same data.
Instead of calling every day with the same recycled excuses, you could construct a “dictionary” of excuses, and just cite one in a conversation. A simple call, “Excuse 42” would be enough, heck, even saying “Excuse” is redundant.
Data compression mechanisms tend to do the same thing, create a table of commonly occurring patterns, and replace the occurrences with something that takes less space. In essence, frequently occurring patterns are replaced with smaller codes while the infrequently occurring patterns might even take up more space than they initially did! However if the algorithm is properly designed, in the end, there is a net positive gain.
Packing Bytes
Try this: create a text file with a single sentence, and keep pasting it until the file is a few MB. This will take time! You will have to paste it thousands maybe hundreds of thousands of times! A better approach is to exponentially increase the amount of text you paste. Paste the sentence a couple of times, select all, and paste a couple of times again. Keep increasing the copy time and soon you will have a reasonably large file1. If you know a programming language you could perhaps write a script. When you compress this file using any program, you will see a drastic decrease in file size, because we have a small pattern repeating continuously. In fact, no matter how large the input file, the final filesize will be in the order of a few hundred bytes!
The aim of compression algorithms is to pack in more information in the same amount of space, to reduce the redundancy of the data. Compressed files have very low redundancy, and it is because of this reason that compressing an already compressed file will not give much benefit. You will not even get any benefit from compressing a “ZIP” file as a “RAR” even though the uncompressed original file might have been better compressed with RAR. Similarly, an uncompressed BMP image or WAV audio file might get compressed quite a bit, while a JPG image or MP3 file will barely benefit from further compression.
Every compression algorithm uses some mechanism to detect patterns, and assign them codes based on how frequently they occur. It is in this selection of patterns and the choice of their codes that makes each compression algorithm unique.
Part 2:Data Explosion:
We often have no idea how much data is behind the content we consume. There is such an information explosion, that not even your uber-cool 2TB hard disk is enough. We may not know it, but some of the most significant data we use today is infeasible unless highly compressed.
Image Data
To see how much compression goes on behind the scenes, take a normal full colour image in BMP format. The image will take up 24-bits per pixel, which is 3 bytes per pixel. This means that to find out the file size you multiply the number of pixels with 3 bytes. So a common 2-MP image will take up around 6MB uncompressed.
While this size may seem rather small considering the size of hard disks today, but for an image used on the internet, this size is exorbitant. The same image as a JPG, would take less than an MB, in all probability.
Now a look at videos.
Video Data
A simple VCD quality video, hardly worth a scoff in today's HD world, has a resolution of 352x288 (PAL), at 24-bit colour, playing at 25 frames per second. A single frame here would be around 352x288x3 bytes = 304128 bytes = 297 kb. Not much? Imagine that coming at you 25 times a second. That would be around, 7.25 MB per second, a single VCD worth of content (around 80 minutes) would take over 34 GB to store!
On comparing that to the actual size of a VCD disk -- around 700 MB -- we can see that what we have is a compression of over 48 times. This high compression is possible even with an outdated and inefficient codec such as MPEG 1. A careful observer may notice that the 700MB on a VCD also incudes audio, something we have not factored in, yet even with that included, we will only get a higher and more impressive compression ratio. Consider that today we have 1080p HD videos which have a resolution of up to 1920*1080, 20 times the resolution of a VCD.
Audio Data
Audio on the other hand is something we have all dealt with in an uncompressed form on audio CDs or even as WAV files on our hard disks. It is comparatively easier to deal with audio in its uncompressed form as they are of significantly lower size compared to video . To compare audio file sizes, an uncompressed audio file of around a minute will be as much as 10MB, while on compression, it is capable of reaching as little as 600 KB (AAC at 80 kbps) giving a ratio of as much as 17 times!
To see how we get to this figure, we take a one minute long 16-bit stereo audio sample recorded with a sampling frequency of 44.1 kHz. A 44.1 kHz sample means 44100 samples in a second, each of 16 bits (2 bytes). Multiplying it all, we get 44100 x 2 = 88200 bytes ~ 86 KB for a second of audio. So for a minute of audio we are looking at approximately 5MB of audio, and since we usually have a stereo audio track which has two channels of audio; we have in effect, 10MB of data per minute. Nowadays we have audio recorded at sampling rate as high as 192 kHz at 32-bit per sample, and with as many as 8-channels of audio (an overall increase of around 34 times)!
It becomes fairly obvious that multimedia is not something to be messed with in its uncompressed state!
Containing the explosion
Even if you do ignore the exorbitantly large sizes, there is another concern that needs be noted. With an HD video of 1080p reaching over a TB in size, how exactly is one to access such volume of data in the 2hrs needed to play it?! Uncompressed HD video is like opening as many as 30 BMP image of 1920*1080 resolution in a second, requiring a read speed of over 150 Megabytes per second for the video alone.
When dealing with such kind of data, even a compression ratio of three or four times is clearly not enough. While audio and images are still quite often compressed using lossless compression formats such as PNG for images and APE, FLAC etc. for audio, traditional lossless measures of compression become unfeasible when used on video. Lossless compression of video is only of use in media companies where the video needs to go through great amounts of editing and compositing before it is finally encoded into the format in which it will be distributed.
Additionally, in the case of audio and video, the compression format should be such that the entire file need not be decompressed just to play the media. All these requirements are clearly not met with our normal compression utilities which offer only lossless compression methods, and require decompression of the entire file before being used. Decompression speed is also very important since huge amounts of data are to be handled, and while it is possible to come up with some innovative compression methods, it is very important that the resultant file be playable on current computers
Besides audio and video, many other kinds of data require great volumes of storage space. Software distributed online is usually heavily packed, because increasing internet speeds, is no excuse for inefficiency. The popular VLC Media player for example, is a ~ 17MB download in its v1, yet after installation it expands to take up as much as 70MB! While such content needs to be compressed without loss of information, it is also not as important for the data content to have as fast a decompression.
Different kinds of data show redundancies in different places, an image might have an entire row or column of a single color, a video might have a few repeated frames, text might have some words appearing more frequently than others. Each data type requires a different approach to detect such redundancies, so that it may be stored in a minimal amount of space.
Part 3: Reducing Redundancy:
Many a new computer user might have wondered, "What if I keep compressing the compressed file?". Zip the rar which has been cab'd and 7zed? Wont you just get a simple clean 1 byte file you could store in that Floppy (You young readers might not know, but way back, almost 10 yeas ago, many people relied on small magnetic disks which could store 1.44MB)
As explained before, this isn't possible, since the aim of a compression algorithm is to juice out all redundancy. And the thing about redundancy is, once it's gone, it's gone.
Taking English text for example, the letter 'e' is the most common of all letters, occurring on an average, with a probability ~ 12.7% with the second 't' lagging far behind at ~ 9.1%.
However the thing is, how would you store an 'e' in less space that it currently takes? All a single character requires for storage is 1byte! This means that to save space everywhere an 'e' is used, we will have to store it in less than 1 byte!
In our normal encoding schemes, we represent each character as a sequence of bits, with each character having a unique sequence. Say 'A' is '01000001', 'B' is '01000010' and so on, we can get a code for each character. However, if every letter takes one byte, we will never be able to compress anything, since everything, no matter what the probability, will take the same amount of space.
In order to get some compression, we need to use a way of generating a code for each character such that the more common letters have a shorter code, and longer ones have a longer code.
Our common 'e', for example could get a nice, single bit '0', and 't' could get a '1'. Even with this simple change, we can analyze the impact on the compression: Both 'e' and 't' are now using a one bit code instead of an 8 bit code. So the compression for each presence of 'e' and 't' is 1/8 (12.5%). This replacement will occur with a 12.7% + 9.1% frequency, i.e. 21.8% of all characters are either a 'e' or a 't'. Therefore 21.8% of the text will be compressed to 1/8th it's size. The final compression will be (1/8)*21.8 + 1*78.2% = 81%.
The file will be compressed to 81% of its original size! Pretty decent for just two replacements.
Of course it is impossible to compress text this way. For one, how would you discern the '0' and '1' of 'e' and 't' from the 0s and 1s which code the rest of the text? One way is to create a unique code which 'pads' each character, something like a space to differentiate between each word. This will mean there will be some restrictions in how each character is coded to.
Let us look at such an example:
In this example we use a HIGH bit ('1') to separate each code. This will mean that we CANNOT use a '1' as part of our character codes, as it will be mistaken for a character separator.
The code for the first most frequent characters in the English language:
LetterCompressed CodeExt. ASCII Code e 1 01100101 t 10 01110100 a 100 01100001 o 1000 01101111 i 10000 01101001
As you can see, we now have a code which is variable in length, unique and identifiable, with each code padded with '1'.
Using this code has essentially resulted in a compression which reduces the size to a quarter of the original size.
The decoder here, will read in '110010' will decode it as follows: Input first character: '1' Sequence: '1' Input second character: '1' Encountered beginning of new character, decode previous sequence '1' as 'e' Sequence: '1' Input third character: '0' Sequence: '10' Input fourth character: '0' Sequence: '100' Input fifth character: '1' Encountered beginning of new character, decode previous sequence '100' as 'a' Sequence: '1' Input sixth character: '0' Sequence: '10' End of input encountered, decode previous sequence '10' as 't' Output: 'eat'
It is clear though that as we go further, the size of the characters code sequence will increase, till we reach 'h' with a priority of ~ 6.1% and a code of '10000000', which is 8 bits. After this point, the code sequence will become larger than the original 8 bits, and will cause an expansion in size rather than a compression. So:
'e' with 12.702% frequency, will be compressed to 1/8 its size. 't' with 09.056% frequency, will be compressed to 1/4 its size. 'a' with 08.167% frequency, will be compressed to 3/8 its size. 'o' with 07.507% frequency, will be compressed to 1/2 its size. 'i' with 06.966% frequency, will be compressed to 5/8 its size. 'n' with 06.749% frequency, will be compressed to 3/4 its size. 's' with 06.327% frequency, will be compressed to 7/8 its size.
After that there will only be an expansion. A little calculation will show you that these characters combined will be compressed to around 44.6% of their original size. This will be offset by the expansion encountered in the other characters.
This way is quite limiting an inefficient, and will yield very little compression in most real world cases. Real compression mechanisms use more complicated methods of creating a code for each character. Such as: Letter Compressed Code e 0 t 10 a 110 o 111
As you can see here, each sequence is unique, and so is the prefix of each code. The word 'eat' here will be encoded as '011010', again a 6bit code, with a 1/4th compression.
This will be decoded in the following manner: Input first character: '0' Sequence: '0' Matches character 'e' Input second character: '1' Sequence: '1' No match Input third character: '1' Sequence: '11' No match Input fourth character: '0' Sequence: '110' Matched character 'a' Input fifth character: '1' Sequence: '1' No match Input sixth character: '0' Sequence: '10' Matched character 't' Output: 'eat'
If you compare the representation of 'eat' in the ASCII and the compressed code, you will notice that the encoded result '011010' has lesser sequences of repeated digits, than '11001010110000101110100'. The redundancy has been lost, and it is difficult to get a further increase in space savings by running the same compression scheme again. With a longer sequence you will notice that in the compressed file, the probability of occurrence of characters will be almost evenly distributed amongst all characters.
All this is great, however, these character frequencies / probabilities only apply on an average. An average text document might see decent compression with such a code, however 'Gadsby' wont get no love from such a compressor!
Compressors can overcome this by generating it's own dictionary of frequencies, and using those to assign codes. Even multi character sequences which are common can be assigned a much shorter code if they occur frequently enough.
Each compression mechanism has its own unique way of finding patterns, and assigning codes. A compressor which 'understands' the data will function better than one which doesn't and will be able to compress better, since it will know where to look for the patterns. As such you are bound to get better compression in an image file with the lossless PNG, than with a standard ZIP file. No matter how sophisticated the compressor, and what kind of data it deals with, it is most likely that it operates on these simple principles.
On September 2, Google Chrome finished a whole year since it launched to the world in that unexpected comic book format. To celebrations the occasion – albeit two weeks late – Google has unveiled the new stable version of their browser, Chrome 3.0.
The version numbers seem to be ticking by faster than we can report them, with Chrome 2.0 being launched just four months ago; still, who’s complaining? According to StatsCounter, the browser already has 7.39 per cent of the market share in India, making it a force to reckon with.
So what does the new version have in store for us? Google Chrome Product Manager Anthony Laforge wrote a long post on of the official blog about the same, and here are the salient points: Faster browsing: This new release of Google Chrome is faster than ever, improving by more than 150 per cent in Javascript performance since the very first beta, and by more than 25 per cent since the most recent stable release.
New Tab Page:
The speed-dial on the New Tab page of Google Chrome has been one of its most popular features and now it's more customisable too. You can now rearrange thumbnails of your most-visited websites by simply clicking and dragging your mouse. Additionally, you can pin thumbnails to a spot so they don't disappear even if your browsing habits change. What's more, you can hide parts of the page you don't want to see, or even opt for a simple list view of all your most visited Web sites.
Omnibox gets icons:
The address-cum-search bar 'Omnibox' of Google Chrome has gotten a much-needed tweak to help users distinguish a search result from a Wiki page and a site you entered from a bookmar in its drop-down menu. The solution? A simple little icon at the start of the URL.
HTML5:
"We're very excited about HTML5 becoming standard in modern browsers, and continued to add HTML5 capabilities to this stable release. We're particularly excited about the
Themes come to mainstream:
While the Google Chrome Themes were initially started as only an option for beta testers, the new Chrome 3.0 will let anyone avail of the theme gallery to spruce up their browser.
The one big disappointment, of course, is the lack of extensions in this new release. Looks like Google still has some creases to iron out there.
You can grab your copy of Google Chrome 3.0 below, or simply go to the ‘About’ section of your Chrome browser and update it automatically.

Google Earth is a virtual globe, map and geographic information program that was originally called Earth Viewer, and was created by Keyhole, Inc, a company acquired by Google in 2004. It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. It is available under three different licenses: Google Earth, a free version with limited functionality; Google Earth Plus (discontinued)[1][2], which included additional features; and Google Earth Pro ($495 per year), which is intended for commercial use.[3]
The product, re-released as Google Earth in 2005, is currently available for use on personal computers running Windows 2000 and above, Mac OS X 10.3.9 and above, Linux Kernel: 2.4 or later (released on June 12, 2006), and FreeBSD. Google Earth is also available as a browser plugin (released on June 2, 2008) for Firefox 3[4], Safari 3, IE6 and IE7. It was also made available on the iPhone OS on October 27, 2008, as a free download from the App Store. In addition to releasing an updated Keyhole based client, Google also added the imagery from the Earth database to their web based mapping software. The release of Google Earth in June 2005 to the public caused a more than tenfold increase in media coverage on virtual globes between 2005 and 2006,[5] driving public interest in geospatial technologies and applications.
A review of ISRO Bhuvan Features and Performance compare to Google Earth:
While Google Earth works on a downloadable client, Bhuvan works within the browser (only supports Windows and IE 6 and above).
The promise of high resolution images has not been kept. While the service promises zoom up to 10 metres from the ground level as against 200 metres for Google Earth, we didn’t encounter a single image with nearly as much detailing. In fact, comparative results for a marquee location such as New Delhi’s Connaught Place or Red Fort make its clear as to the inferior performance of ISRO Earth as of now.
The navigation tools are similar to Google Earth (GE).
The search doesn’t work if a query returns multiple results. A pop up window is supposed to give the multiple results from which the user is supposed to be able to choose. During two days of sporadic testing, we found the result only once. The rest of the time, the window would pop up, but nothing would be displayed. When the search is accurate, the software ‘flies in’ to the exact location, the same way as GE.
Users need to create an account and download a plug-in.
Users can also not edit any data or tag locations.
The ISRO Bhuvan currently has serious performance issues. The site currently very unstable. It gives up or hangs the browser every once in a while. When a layer (state, district, taluk, etc.) is turned on, it renders unevenly and sometimes fails to render at all. The navigation panel failed to load routinely and it felt like a rare sighting when we could actually use the panel.
We hope Bhuvan is able to fix the bugs soon. But even then, to be a credible alternative to existing mapping services, and even to get new users to try it, it much provide much higher resolution images. User interest will be piqued only when they can see their house or school or local street in high resolution. With Isro data, this is easily doable.

The mobile number portability project is one of the most ambitious and long-awaited in the telecom sector in India. But as the scheduled kick-off date of September 20 draws nearer, the Indian Government has yet again thrown a spanner into the cogs and postponed the implementation date by three months.
As usual, it seems that the reason is the cold war between the country’s two premier telecommunications bodies: the Department of Telecom (DoT) and the Telecom Regulatory Authority of India (TRAI). Following the telecom sector news for the past few years, it is apparent that the two departments silently strive for one-upmanship and are constantly on the lookout to run the other down. And that’s exactly the case here, with the common man suffering in the bargain.
On Thursday, the DoT extended the implementation date for mobile number portability (MNP) to December 31. Number portability is a facility that allows subscribers to change their mobile service provider while keeping the same number. Digit had previously reported that TRAI has issued guidelines for the same which would enable the process to be finished within a week.
The 100-day delay in the scheduled execution of MNP is attributed to operators' inability to upgrade their network as well as to the delay on part of regulator Trai to come out with tariff for the service.
The DoT released a statement saying: "The implementation of MNP is under progress. However, this required customisation and upgradation of the existing network to be capable of providing the MNP service. Certain technical and commercial issues related to it are also being resolved. All this requires considerable time and effort. Therefore, it has been decided by the Department of Telecom to extend the date of implementation of MNP in Metro Category A service areas to December 31, 2009 in the first phase.”
Metro Category A cities include the mobile circle areas of Mumbai, Delhi, Chennai , Kolkata, Maharashtra, Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka.

KMPlayer 2.9.4.1435 is a free versatile media player which can cover various types of container format such as VCD, DVD, AVI, MKV, Ogg Theora, OGM, 3GP, MPEG-1/2/4, WMV, RealMedia, and QuickTime among others. It handles a wide range of subtitles and allows you to capture audio, video, and screenshots in many ways.The player provides both internal and external filters with a fully controlled environment in terms of connections to other splitters, decoders, audio/video transform filters and renderers without grappling with the DirectShow merit system. Internal filters are not registered to user’s system to keep it from being messed up with system filters.The KMPlayer includes almost all the essential decoders required for media playback. Furthermore, to get beyond the limitation of internal decoders, the external ones such as commercial h.264 decoders or cyberlink/intervideo audio decoders can be specified, so that KMP works optimally by the users’ own customization. Even though the KMP is based upon directshow structure, it supports Winamp, Realmedia and Quicktime by the internal logic. Thus, it is possible to specify where to try to connect firstly the media in preferences.
