GGMMTV PROPRIETARY COMPRESSION TECHNOLOGY

From the onset GGMMTV has identified the need to improve on H.264 compression technology. It is not that H.264 is an inferior compression technology, but it was designed back in 2003 and was for video streaming requiring a comparatively higher bandwidth (compared to today's standard). In this respect H.264 encoded 720x576/25fps video will strain in today's demand of DVB using a bandwidth of less than 786Kbps (the practical bandwidth of 3.5G HSDPA).

Understanding that the world is becoming mobile, and that bandwidth is the key to mobility and global coverage, GGMMTV sees that there is a real need for advance compression technology. The criterion of GGMMTV proprietary compression technology is simple: to achieve the best possible streaming video quality using a bandwidth of less than 1Mbps.

GGMMTV's proprietary compression technology: HVMT (High-quality Video Media Technology) is so advanced that it enables a standard 2.5G mobile phone with GPRS access to view streaming video at 176x144/6fps. Noting GPRS has a practical usable bandwidth of less than 56Kbps! During a live demonstration to a leading mobile network provider in Hong Kong, their senior engineer/developer said "ˇKseeing this live feed via GPRS is a miracle".

The following chart compares the PSNR (Peak Signal to Noise Ratio) / Bit Rate in Kbps between our proprietary HVMT compression with H.264 (encoded using Nero Burning ROM), Windows Media Video 9, and MPEG-4 (DivX).

Typical values for the PSNR in image and video compression are between 30 and 50 dB (decibels), where higher is better.

Our proprietary HVMT compression maintains best quality at all Bit Rates, even at 100 Kbps, HVMT manages to maintain a PSNR of over 40 dB.


HD TV for Personal Computers

Using this same proprietary compression technology, GGMMTV is able to encode 1280x720/25fps video using a bandwidth of less than 1.5Mbps, and 720x576/25fps video using a bandwidth of less than 512Kbps. Therefore for 720p HDTV, if the monitor output of a notebook computer is connected to one of the latest LCD HDTV screen, HD TV becomes immediately available.

The high video quality with a low bandwidth requirement is the key to GGMMTV's HVMT compression. Another practical use will be to provide high quality VOD 720x576/25fps at less than 512Kbps to viewers overseas.

The delivery method deployed by GGMMTV can either be Server-to-Client or Peer-to-Peer. With all things being equal (i.e. same number of peers, same file size, and same bandwidth) our proprietary compression technology will enable our player ("GMT Player") to deliver a more stable and jitter-free content than any other players on the market: simply because our delivery method requires less bandwidth. This extra stability due to the lower bandwidth requirement is vital in the global Internet environment where Internet transmission can be quite unstable.


HQ TV for 3G Mobile Phones

GGMMTV's HVMT compression already allows audio/video to be broadcasted to GPRS enabled mobile phones. Thus with a higher bandwidth of the 3G and 3.5G mobile networks, GGMMTV is able to deliver unprecedented sound and video to these mobile phones. The fact that GGMMTV is not using any H.264 hardware based graphics accelerator, literally any 3G enabled mobile phones will be able to view High Quality TV transmitted via the 3G network at 320x240/15fps QVGA.


Electronic News Gathering ("ENG")

Already on beta testing, GGMMTV has designed and implemented a mobile system (using a high specification notebook computer and USB video capture device) which allows a live TV signal to be captured (720x576/25fps) and transmitted over a wireless IP connection of 512Kbps back to the broadcaster's studio. The implication is far and wide reaching. No longer will ENG require a microwave transmitter for live broadcasts, and an uplink to a satellite transponder will no longer be a necessity, saving the broadcaster transportation and transmission costs.


Next Generation Compression

GGMMTV will not rest on its laurels, our technical team is in the final stages of implementing the next generation proprietary compression technology enabling 1280x720/25fps video streaming at 384Kbps. GGMMTV hopes to have this feature before the end of 2008, although a beta version is already available.

 
News & Events
With HVMT encoded video, it enables a standard 2.5G mobile phone with GPRS access to view streaming video with sound at a resolution of 176x144 pixels at 6 frames per second ("fps"); noting GPRS has a practical usable bandwidth of less than 56Kbps.

Under a 3.5G HSDPA environment with a bandwidth of less than 768Kbps, HVMT encoded video is able to display high-quality QVGA video at 320x240 pixels with 15fps.

For standard television use, HVMT can display quality video of 720x576 pixels at 25fps using a bandwidth of less than 512Kbps.

And for 720p HDTV, HVMT can display quality video of 1280x720 pixels at 25fps using a bandwidth of less than 768Kbps.
