Single-chip decoders for professional customers CS24 Digital Audio/Video Decoders Figure 1: IBM’s single-chip digital audio/video decoders integrate advanced features for highperformance solutions. Highlights ! Single-chip decoders for Enabling cost-effective, A flexible, single-chip solution for value-added products high-performance systems The IBM MPEG-2 digital audio/video IBM’s family of CS24 decoders decoders, CS24, CS24E, CS24D, features an integrated transport and CS24DE, are advanced, high- stream demultiplexer, MPEG-2 video performance chips designed to satisfy decoder, dual audio decoders, and the needs of customers developing an SDRAM interface. By integrating professional audio/video products. these features on a single chip, the These single-chip decoders are decoders enable more complex intended for professional audio/video designs while helping to reduce editing, broadcast, and a range of design time and effort. emerging applications. Integrated transport The IBM family of CS24 decoders stream demultiplexer can decode MPEG-2 4:2:2 Profile at The integrated transport stream Main Level video, Main Profile at Main demultiplexer accepts continuous Level (MP @ ML) video, and MPEG-2 input at a rate of up to 160 Mb/sec in audio/video editing, broadcast, stereo Layers I & II (CD-quality) audio. parallel format or 60 Mb/sec in serial and emerging applications The CS24D and CS24DE also offer format.
