    Design Considerations

    A Video Conferencing system can be broken down into two categories: client endpoints/terminals and video conferencing infrastructure systems. Texas Instruments high-performance DSP, analog, and logic products enable a feature-rich, robust, and cost-competitive video conferencing solution.

    Client Endpoints/Terminals

    Video conferencing client endpoints are terminals that can be used to make point to point calls. It typically consists of a camera and a base unit that performs video compression algorithms to reduce network bandwidth and transmits the stream via IP or ISDN networks.

    Texas Instruments video conferencing client endpoint solutions are based on the high performance DM64x Digital Media processors which have integrated on-chip video ports for easy hookup to a multitude of video devices. The DM64x family is capable of simultaneously handling both audio and video encode/decode for IP based video conferencing applications. Cost competitive video algorithms are available through our third party network including the H.263 and H.264 suite of video codecs. Audio codecs are also available including G.72x algorithms.

    Infrastructure Systems

    Video conferencing infrastructure includes MCUs (multipoint conferencing units) which allows the connection of three or more video conferencing systems in the same conference. The MCU manages the audio and video from each participant and enables live group communication between all parties.

    Texas Instruments video conferencing infrastructure solutions are based on the high performance C64x and DM64x (Digital Media) family of processors. These devices provide the horsepower required to process multiple streams of video conferencing sessions. Highly optimized, cost competitive H.26x video codecs, H.32x protocols, G.7xx audio codecs, TCP/IP networking stack, and other streaming protocols are available through our third party network.
