What operating systems support Ultra-Videoconferencing?
Ultra-Videoconferencing currently runs only under Linux systems. The release version has been compiled under Ubuntu Gutsy and is forward compatible, to the best of our knowledge, to current releases, through Intrepid. Your mileage with other Linuces may vary. • What are the CPU requirements for Ultra-Videoconferencing? The CPU requirements depend entirely on what modes of transport and coding are involved. Ultra-Videoconferencing requires fairly minimal CPU power for audio-only transport, but requires PIII-1GHz or better for DV or JPEG decoding, and greater power for HD-SDI video (with a custom kernel to provide 1 kHz scheduler). • How much network bandwidth is needed for the various modes supported by Ultra-Videoconferencing? PCM audio with default sampling (44.1 kHz, 16 bit) requires approximately 706 kbps per channel. DV camera output (audio and video) consumes approximately 25 Mbps; JPEG-encoded full-frame video is similar. Uncompressed analog or dc1394 video at full-frame requires
