The VW2010 accepts uncompressed ITU-R.BT-656 video and I2S audio, compresses the video into MPEG-1, -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.
