SPHE1003 A/V decoder is a cost-effective DVB STB A/V SoC. It integrates a front-end COFDM (Coded Orthogonal Frequency Division Multiplex) DVB-T demodulator, back-end MPEG-2 transport demulitiplexer and MPEG-1/-2/-4 A/V decoding engine with a 2-channel audio DAC and a 4-channel multi-format TV encoder. SPHE1003 DVB-T demodulation is compliant with ETSI EN 300 744 specification while it can be used in either 2K or 8K modes with 6, 7, or 8 MHz channels and supports QPSK, 16QAM, 64QAM reception. SPHE1003 also supports CVBS, S-video, component YCbCr/YPbPr and RGB video output formats.

SPHE1003 performs a real-time PID filtering of transport stream, decoding and playback of MPEG-1 and MPEG-2 A/V from DVB Half NIM. Multimedia video and audio such as MPEG-1, MPEG-2 and MPEG-4 video or MPEG I/II layer 1/2/3, PCM, LPCM audio or HW JPEG can be played through SD/MMC/MS/MS-Pro card reader or USB 2.0 mass storage by SPHE1003's real-time decoding.
