Video 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 contrast, MPEG-2, MPEG-4, Windows Media, Real Video,
and QuickTime are "asymmetric" CODECs - that
is, they take much longer to encode than to decode and
are designed for "Store and Forward" applications.
They are not suitable for real-time viewing and conferencing.
For example, MPEG-4 can take up to 10 seconds to compress
one frame of video on a 2 GHz Pentium-IV (non-hardware
KT-Tech's video codec can compress one frame of video
in .03 seconds on a Pentium IV (non-hardware assisted).
This makes KT-Tech's algorithm outstanding for real-time,
2-way video conferencing.
Super Small and Super Fast in Software
KT-Video Software takes up less than 85KB on the PC
(both encoder and decoder, each<85KB) compared to
13 MB for Microsoft Windows Media (that is, KT-Tech's
Video Decoder/Viewer is less than 0.7% of the size of
KT-Video offers TRUE Real-time 2-way communication via
symmetric Encoder/Decoder (up to 10 times faster encoding
than Windows Media, or MPEG-4).
Seeing is Believing: We can demonstrate KT-Video's robust performance over
the internet and wireless networks on existing equipment!
