The BCM7318 includes versatile transport demultiplexing, MPEG-2 video decoding, a high-quality 2D graphics engine, a video encoder, and a MIPS32-based microprocessor. The BCM7411 supports high quality MPEG-4 AVC video decoding. Superb multiformat audio decoding quality supports the latest audio standards, including MPEG-1/2 L1/2/3, AAC, aacPlus, Dolby Digital and Enhanced Dolby Digital (AC-3+) with ample headroom for post processing. All system memory and peripheral control is included to complete the IP set-top box system. The BCM97318AVC includes an extensive software suite that has been developed for the IP set-top box environment. Based around the Broadcom Porting Interface, software developed for the prior generation reference designs is portable to this latest IP set-top box development platform and can be leveraged by Broadcom customers. This extensive software suite developed for set-top box applications includes software for versatile network front-end interfaces and NIM's, audio and video decoder, graphics subsystem and Internet Protocol delivery schemes. Broadcom supports industry standard operating systems and APIs in this design. By developing with the Broadcom Porting Interface, applications can be easily migrated to next generation devices. Broadcom's device drivers are compatible with industry standard operating systems and associated APIs that allow applications and content developed for set-top boxes to run on this platform, with minimal effort by our customers. The BCM97318AVC includes schematics, gerber files, bill of material, data sheet, user manual, `Brutus" software source code and sample application software support.
