NDV8501

PRELIMINARY September 2000 MediamaticsTM NDV8501 DVD on a Chip Processor General Description Platform The MediamaticsTM NDV8501 DVD on a Chip Processor provides next generation features and cost effective system integration for Universal DVD Players and Internet connected Players/Recorders. Integration of an industry standard RISC processor architecture operating at high performance levels allows system developers to combine the ease of C based application coding with flexible system extensions unavailable in other platforms. This processor can be equally applied to DVD-Video & DVD-Audio playback, DVD recordable solutions, Hard Disk Drive based recordable solutions and Internet Appliance products. common disc-based audio formats and many Internet based formats. A custom 24-bit DSP has been developed to provide a powerful solution for the latest compute intensive audio algorithms. Support for common DVD-Video, VideoCD and CD formats has been carried forward from previous generation devices and in addition, support for DVD-Audio formats, DTS, MPEG-2 multi-channel, Dolby Prologic, HDCD and MP3 have been added. Karaoke processing and a royaltyfree 3D Stereo Surround implementation are also provided. The flexible audio structure allows audio data to originate from disc-based media, external digital audio streams or via the Internet. Full 5.1 channel output with simultaneous 2-channel down-mix and IEC958/1937 output is standard for the NDV8501. Audio The NDV8501 provides unsurpassed audio processing quality and flexibility with wide ranging support for all Features The NDV8501 is a 2nd generation “system on silicon” solution for consumer DVD Players. Significant feature enhancements are being provided on the NDV8501 device to address both full-featured DVD-Players and DVD-R/W Recorder/Player products.
