MPEG Reading material

From: Fred on 12 Apr 2010 09:04 Can anyone recommend a cross beween reading material and reference material for MPEG coding? I am familiar with JPEG, and the JFIF file structure and would like to know more about MPEG, preferably to include MPEG-4 with a view to coding MPEG4 streams.

Can anyone suggest an alternative group to ask the question?

For reference material, the MPEG-4 Wikipedia page has links to all the ISO standards documents. More than you could ever want to know I imagine! MPEG-4 covers an awful lot of ground! For something that's a "cross-between reading and reference material" as you asked, I think you'll have to give more idea as to what level you want to read at, sorry!

Try comp.compression. MPEG-4 covers a vast amount of material. It sounds like you're interested in video coding, so you're probably interested in MPEG-4 part 2 and / or MPEG-4 part 10 (a.k.a. AVC or H.264). Each of these offers a variety of tools that can be used to increase compression efficiency, at the expense of increased complexity. H.264 is more efficient and more complex than MPEG-4 part 2. Are you thinking of building an encoder or decoder in FPGAs? This is a relatively big deal. The decoder would be much easier than the encoder, so that might be a good place to start. I have H.264 and MPEG-4 Video compression by Iain Richardson, and The MPEG-4 Book by Pereira and Ebrahimi. Both are reasonable introductions. It used to be possible to download some ITU documents for free from the ITU. It may still be. If so, you should download the H.264 specification. The ITU doesn't have a version of MPEG-4 part 2, so you'll have to pay the ISO for that. You might be able to download a copy of H.263 from the ITU for free. This has a slight overlap with MPEG-4 part 2 which has a compatability (short header) mode that is essentially H.263. Pete

In the past I have found ISO standards unreadable though good for reference. I wanted more a book I could read on trains or waiting for appointments. But a book where I would get more than an overview with some depth. I am very aware that H.264 is very involved but would like to be in a position where I could write some code, or at least understand the basis on which existing code has been written. |
