Based upon its patent pending still compression technology, KT-Tech has developed a high quality, low bit-rate, symmetric and real-time video codec suitable for Internet and wireless on-demand streaming and conferencing. "Symmetric" means that encoding the video is as fast as decoding. In other words, any computer, PDA, or wireless device that can display the video can also encode the video, in software and in real-time.

In addition, in contrast to Windows Media 8 or Real Video, both of which require a buffer time of at least a half of a second, KT-Tech's video codec can work with a buffer of a single frame. That makes KT-Tech's algorithm well suited for real-time video conferencing.

The following is a single frame from a low bit-rate video sequence clearly demonstrating KT-Tech's superior performance:

KT-Tech 32 Kbps, 8 fps

MPEG-1 56 Kbps, 8 fps

H.261 32 Kbps, 8 fps

Since KT-Tech's algorithm can perform real-time software encoding, we chose to compare our performance against MPEG-1 and H.261 since they are the closest in terms of encoding complexity.

Movie Demo Downloads

The following is a downloadable demonstration of KT-Tech's movie encoder. Though KT-Tech has the ability to encode phone-quality audio at 8 Kbps, currently the sound is stored separately in a WAV file. Therefore, bandwidth readings only include the video encoding. We will be happy to show you KT-Tech's breakthrough, true real-time, any-bandwidth video/audio technology running over the Internet on your own equipment. Please contact us at rlerner@kttech.com to set-up a mutually convenient time for a demonstration.
