Santa Clara, California-based Integrated Information Technology Inc has introduced the VCP, a programmable processor for video and multimedia communications applications. It performs a superset of the functions of its predecessors, the Vision Controller and Vision Processor, by adding programmable video pre- and post-processing capabilities, communications features, along with other system-level functions. It can enable systems designers to create videoconferencing systems, video phones, desktop video playback and authoring systems, and other multimedia applications requiring high-quality, real-time video compression. The VCP is a single-chip, programmable video codec and bitstream multiplexer for all standard and proprietary video compression algorithms and will perform H.261 video compression at CIF and QCIF resolutions and H.221/H.242 video and audio multiplexing for the creation of a complete H.320-compatible videoconferencing system. The processor supports MPEG-1 and MPEG-2 video, audio and system decode and can compress and decompress JPEG still images. The VCP provides support for the time-division multiplexed bus used in many PABXs and a serial interface to an audio signal processor. The pre- and post-processing functions include picture-in-picture support and on-chip scaling between PAL, NTSC, CIF and QCIF resolutions. With a 32-bit external static RAM port, the VCP can use slower, less expensive statics than current systems, and code can be paged in from dynamic RAMs. Audio compression is handled by an external signal processor, and the audio bit stream is multiplexed and demultiplexed on the VCP, eliminating the need for external multiplexers. Code developed on the Vision Controller and Vision Processor needs converting for use on the VCP but the company claims this is easily carried out. Current customers can change to the VCP and enhance performance while reducing board space and component costs. The VCP has a fully programmable architecture, and development tools will be available enabling customers to implement their own proprietary technology as well as using the standards-based systems provided by the company. It will be available in sample quantities in the first quarter of 1994 in speeds from 20MHz to 66MHz. A version clocked at 80MHz be available later in the year. The price is between $140 and $400 per 1,000, depending on the speed grade. An evaluation board will be available the first quarter of 1994.
