MPEG4 is a big standard that includes (among other things) lots of video compression algorithms. One of those is H.264 which is found in MPEG4 Part 10.

AVCHD is a standard file format that includes video compressed using the H.264 algorithm.

So there is some overlap. The MPEG4 standard says nothing about the AVCHD file format but it does define the AVCHD video compression algorithm.

Many companies advertise ‘MPEG4 playback’ but that actually has very vague meaning. What they probably mean is that the device can play DivX files or MP4 files. It’s unlikely to include AVCHD. However, most (all?) Blu-Ray DVD players can play AVCHD files. You’ll probably want a Blu-Ray player or you’ll have to convert your AVCHD files into some other format.

I am planning to get a AVCHD camcorder. I plan to archive my home videos to a portable drive and use a Digital Media Player which connects to the portable drive and stream the video to an HDTV. Most of the consumer units that I found do play WMV, MPEG2 and MPEG4 but not AVCHD. I am trying to avoid having to converting from AVCHD to WMV or AVI.

Is AVCHD the same as MPEG4 or is AVI the same as MPEG2 or MPEG4?

Thank you.
