mo\eable, lockable, tip-proof cabinet, (l) Keyboard, (1) mouse, (2) Audio mixers, (l) VCR with remote control. One monitor should be optimized for display of data. All necessary cables and wiring to install in classroom. Connectivity: LAN, WAN or Internet capable, H.J20 upgradeable to H.J23, TIlEl line rate, Ethernet or token ring LAN card. All equipment \vill be Year 2000 compliant. The videoconferencing system must meet the ITU- T H.320 (Video System) or H.323 standards (most recent version), provide interactive two-way video with two-way audio, two-way data capabilities and provide multi- point capability. Multi-point capability is defined as video conferencing with more than two sites. All videoconferencing equipment proposed must support ITU- T (International Telecommunications Union - Tel ecomm uni cati ons) Recommendati ons. The videoconferencing system must have a transmitted picture frame rate suitable for the intended application but shall be a minimum of 30 frames per second (Recognizing the balance needed between picture frame rate. video and audio quality and the associated network bandwidth.) The H.320 codec must meet the ITU- T H.261 (Video Coding Algorithm) standard and the H.323 codec must meet either the H.261 or H.263 standard. The codec must perform video and audio encoding and decoding. Recognizing that the video codec is optional in H.323, the H.323 videoconferencing system must include the video codec. The common intermediate format (CIF) and the quarter CIF (QCIF) shall be provided by the codec, recognizing that only QCIF is mandatory in H.261 and only sub-QCIF and QCIF are mandatory in H.263. Quality of video in many classroom distance learning and group video conferencing applications \vill require CIF as \vell as the ability to maintain quality of service interconnections with other organizations in the education community. For group classroom distance learning and group video conferencing applications, the codec must support both single and dual configurations. (NOTE: Contact your principal content provider for any required network interfaces.) Audio/video lip synchronization is required. The codec shall support full duplex, fully interactive bridged audio with active echo cancellation for group classroom distance learning and group video conferencing applications. The video conferencing system must provide audio/video/data transmission rates suitable for the intended application but must provide rates up to 384 kbps. Recognizing the balance needed between picture frame rate, video and audio quality and the associated network bandwidth (transmission rate), consideration must be given to have the capability to operate at 512 kbps and 768 kbps for group classroom distance learning and group video conferencing applications and interconnection with other organizations in the education community. Applications requiring data communications must support the ITU-T 1.120 series of standards. Applications \vith appropriate requirements must be able to access a LAN for data storage and retrieval as well as provide World Wide Web Internet access while the system is active. The videoconferencing system must include student camera and a faculty camera, Document camera and viewing monitors for participants should be included for applications of group ]1
