Chipset suits video conferencing and telepresence systems.

March 28, 2007

Featuring WW10000BA single chip encoder and WW10001BA single chip decoder, WW10K H.264 HD codec chipset has encode-decode tandem delay of less than 35 msec, or 1 frame at 30 frames/sec. Chipset runs at 110 MHz in single chip implementations and can handle up to 4 video inputs simultaneously at various bit rates and resolutions up to 1,920 x 1,088. WW10001BA decompresses encoder's bit stream into either 1080i/p or 720p HD video. Read More

Codec decompresses coded streams.

December 6, 2002

Model 516 MPEG-2 codec, in PC/104 format, overcomes low bandwidth of PC/104 bus by compressing audio and video at 30 fps for NTSC and 25 fps for PAL. Stream bit rate is programmable from 100 Kbits/s to 10 Mbits/s. A 64-character buffer adds text to each frame. When combined with Model 301 CPU, compressed data from up to 4 codecs can be transmitted at full frame rates over Ethernet. Model 516 can decompress encoded streams to produce composite, S-video and audio. Read More

MPEG-2 Codec is suitable for PCI bus with audio.

November 20, 2002

Offered in PCI format, Model 616 reduces CPU usage and memory storage by using hardware to compress audio and video at 30 fps for NTSC and 25 fps for PAL. Compressed data enables video transmission at full frame rates over Ethernet. System stream bit rate is programmable from 100 Kbits/s to 12 Mbits/s. Stereo audio is synchronized and imbedded into video stream. Additional offerings include 64-character buffer, 3 opto-isolated input lines, and 3 relay outputs. Read More
