Hi, MPEG-1 video will be decoded by MPEG-2 video decoder. I am not sure about audio. regards, ramkishor Architect - Video Codecs Multimedia Technologies Division Emuzed India Bangalore www.emuzed.com ----- Original Message ----- From: "Federico Sambilay" <> To: <> Sent: Monday, February 16, 2004 4:12 PM Subject: [imagedsp] MPEG-1/2 compatibility > Hi! > > Can an output of an MPEG-1 (audio/video) encoder be > decoded correctly by an MPEG-2 decoder? > > Thanks! > > __________________________________ > > > _____________________________________ > > Yahoo!

I think yes, MPEG2 decoder can decode a valid MPEG1 bitstream... ...but can an MPEG4 decoder decode a valid MPEG2 bitstream? --- Federico Sambilay <> wrote: > Hi! > > Can an output of an MPEG-1 (audio/video) encoder be > decoded correctly by an MPEG-2 decoder? > > Thanks! > > __________________________________ __________________________________ |

Hi, If the decoder supports MPEG2 BC (backward compliant) mode, then MPEG2 BC audio decoder can play MPEG1 audio. There is another non backward compatible (NBC) mode. If audio decoder is AAC compliant, it won't able to play MPEG1 audio.
