AL9V576 MPEG-4/2/1 Audio/Video Encoder

Manufacturer:  

Averlogic Technologies

MFG Part #:  

AL9V576B-LF2-PBF

Part #:  
AL9V576B-LF2-PB
Availability   Short Lead Time
RoHS Status:   Available RoHS Compliant
AL9V576 is a real-time MPEG-4/2/1 video/audio encoder chip that fully complies with ISO/IEC-11172, ISO/IEC-13818, and ISO/IEC-14496. The video encoder accepts umcompressed ITU-R BT.656, ITU-R BT.601, 16-bit YCbCr, or 24bit YCbCr/RGB digital video. It filters the input and compresses the video into MPEG-4/2/1 formats. The audio encoder accepts two independent channels of digital audio, filters the input, and compresses each audio into MPEG-1, and MPEG-2 audio formats. AL9V576 multiplexes the video and audio streams as transport streams for network applications or program streams for storage applicaitons.
