VW2010 MPEG-1, -2, -4 Audio/Video CODEC ChipChip
Product Brief
The VW2010 is a real-time MPEG-1, -2 and -4 audio/video/system CODEC chip (simultaneous compression/ decompression, or encode/decode) that fully complies with ISO/IEC-11172-2, ISO/IEC13818-2, ISO/IEC-14496-2 and ITU-T H.263. The VW2010 accepts uncompressed ITU-R.BT-656 video and I2S audio, compresses the video into MPEG1, -2, -4 or H.263 formats, compresses the audio into MPEG-1, MPEG-2, MP3, AAC or AC-3 audio formats, and outputs them as transport streams for network applications or program streams for storage applications. In addition, the VW2010 accepts an MPEG bitstream input, and outputs ITU-R.BT-656 video. It also accepts an MPEG-1, MPEG-2, MP3, AAC or AC-3 audio bitstream input, and outputs audio through I2S, S/P-DIF or IEC-61937. * Dynamically adjustable controls * Fixed frame rates of 29.97 (NTSC) or 25 (PAL) frames per second, or variable frame rates in low delay mode * Constant or variable bit-rate from 22.5 Kb/s to 15 Mb/s * Horizontal resolution between 128 and 720 pixels in 16-pixel steps * Vertical resolution between 80 and 480 pixels (NTSC) or 576 pixels (PAL) in 16-pixel steps * Programmed GOP structure and length: I, IP, IBP and IBBP * Programmed low delay mode
