 SPHE8281D A/V decoder is a single-chip integrated DVD A/V decoder.
It is designed to maximize system performance with minimum cost.
It integrates DVD/CD controller, host processor, A/V decoding hardware, audio quality DAC and a 6-channel multi-format TV-encoder.
SPHE8281D supports DVD and CD physical formats.
For logical formats it supports DVD-Video, Super Video CD, Video CD, CD-DA, OKO, and CD-ROM discs.
SPHE8281D performs real-time decoding and playback of ISO/IEC 11172 MPEG1, 13818 MPEG2 sources.
Besides MPEG A/V decoding, it supports Dolby Digital and MPEGI/II Layer1/2, PCM, LPCM audio playback.
SPHE8281D also combines all the functions required for a high-performance progressive-scan DVD system.
Built-in de-interlacing hardware allows high quality DVD playback.
The embedded digital audio decoder is able to support key control and audio sound effects for Karaoke.
Development tools of SPHE8281D include complete compiler tools, programming guide and system application libraries.
