I'm a Media Tech student and last year I did a module on compression and for my assignment I had to answer a question on MPEG standards. Part of the question was about MPEG 7 and even higher revisions, now I couldn't find anything about anything higher than 4 so didn't answer the question fully. Has anyone know of such a standard? Or is my lecturer losing his mind?
This was a trick question:
Mpeg7 is a proposed standard to describe the multimedia content. I is not a compression standard. (I bet you Prof went the the Meeting in Bristol last year where there were a number of meetings on this topic. What is becomming more important these days it being able to identify content and describe this content. This becomes important for searching indexing etc. That is what Mpeg7 is all about. NOT A COMPRESSION CODEC. Mpeg4 is currently as far as that goes, where the big difference is the inclusion of Meta data or a separate stream of information that tells you what decisions the compresssion codec used, describes thing better. In essence the big next change is not requiring the codec to be able to detect SOLELY from the compressed file what to do on decompression, instead adding additional information to assist.
Rather an oversimplification but hope it helps.

Thanks greatly, at least now I have a idea, and some were to start. Do you know whether there are any journals or articles about MPEG7 on the net?
Here are two good locations:

If you search on the net you need to also use MPEG-7
