MPEG-4 will transform Internet-based multimedia by delivering breakthrough video and audio quality, flexibility, and control. Now, there's a complete guide to MPEG-4 for everyone who wants to take advantage of it, from Internet media programmers to senior decision-makers. In MPEG-4 Jump-Start, two leaders of the Internet multimedia community introduce every aspect of the MPEG-4 standard: its fundamental concepts, capabilities, applications, requirements, limitations, and more. Walk through everything you need to know to start working with MPEG-4 today, from installing players and finding content, to creating and distributing your own content. Understand the underlying technical capabilities of MPEG-4 from a programmer's perspective, and learn why it represents a breakthrough solution for any networked environment -- Web, satellite, or even wireless.
