Milpitas, Calif. A new system-on-chip from C-Cube Microsystems Inc. is said to enable digital time shifting, consumer product connectivity and advanced content display in digital set-top boxes.
Dean Westman, vice president of marketing for C-Cube's broadband network division, said the fourth-generation AViA-9600 integrates a 150-MHz RISC CPU host, an A/V decoder, an audio DSP and a graphics processor, the latter based on input from service operators searching for advanced video and graphics display capabilities.
The AViA-9600 is said to provide both IEEE 1394 (Firewire) and USB controllers for connecting digital cameras and camcorders, external hard drives, DTVs and printers for viewing, editing or transmitting personal media content on the TV or through broadband networks. An IDE controller provides direct connection to hard-disk drives for time-shifting and datacast applications.
Westman noted that the part is partitioned to provide seamless connectivity to cable, satellite and terrestrial broadband networks, so set-top box makers can adopt a common platform and still address multiple markets.
Besides integrating an ATA/IDE controller to connect with disk drives for time shifting and personal video recording, the AViA-9600 integrates both 5C copy protection circuitry for IEEE 1394 and Content Protection for Recordable Media encryption for content on the hard-disk drive. The part's MPEG decode engine also allows consumers to pause, review and fast-forward recorded video.
The AViA-9600 graphics subsystem employs a Display List Processor (DLP) architecture to help provide more intuitive electronic programming guides and to display Web content. The architecture is said to offer advanced windows management capabilities and to support an almost unlimited number of planes and arbitrary-shaped regions with minimal CPU overhead.
The AViA-9600 offers DVB and DES support and the ability to handle MPEG, DVD and DSS formats. Westman said its audio DSP delivers a complete home theatre experience by processing audio formats including MP3, MPEG-2, Dolby Digital and DTS. Samples of the AViA-9600 are due in the fourth quarter, with production quantities set to follow in the first quarter of next year.
The part is packaged in a 308 ball-grid array and is priced at $22 in quantities of 100,000.
