  • 功能特点

    •SPHE1002 A/V decoder is a cost effective DVB STB A/V decoder. SPHE1002 can be applied in DVB STB, in Terrestrial, Satellite, and Cable fields, either in Free-To-Air or in Conditional Access/Common Interface applications. It integrates a MPEG-2 Transport Demulitiplexer, a MPEG -1/-2/-4 A/V decoding engine, a 2-channel audio DAC and a 4-channel multi-format TV-encoder. SPHE1002 performs a real-time PID filtering of transport stream, decode and playback of MPEG-1 and MPEG-2 A/V from DVB NIM. Multimedia A/V functions, such as MPEG-1, MPEG-2 and MPEG-4 video or MPEGI/II Layer 1/2/3 , PCM , LPCM audio, can be real time decode and playback from SD/MMC/Memory Stick/Memory Stick Pro multi-in-one memory card or USB 2.0 Mass storage Device inputs by SPHE1002.
