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. NDV8501 can be equally applied to DVD-Video & DVD-Audio playback, DVD recordable solutions, Hard Disk Drive based recordable solutions and Internet Appliance products.

Audio
The NDV8501 provides unsurpassed audio processing quality and flexibility with wide ranging support for all 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 of NDV8501 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.
