ABSTRACT:

 

The release of MPEG-4 has introduced new options, and questions, into the already complex arena of multimedia streaming. MPEG-4 is an open standard defining method for encoding, storing, transporting, and decoding multimedia objects on a variety of playback devices. MPEG-4 uses an 'object-based' paradigm that, in it's full glory, 'extracts' different elements from visual scenes and transmits them within 'elemental streams' that have independent interactivity and scalability. The standard also provides seamless interoperability over a wide variety of bandwidths and platforms. In principle, these capabilities seem to define MPEG-4 as a revolutionary multimedia format destined to replace established streaming architectures such as QuickTime and Windows Media. However, in the present abstract we question whether this will actually be the case. Our demonstration will (1) present an introduction to the basic technology underlying the MPEG-4 landscape, (2) review what authoring tools are currently available to allow use of this open standard, and (3) compare the quality and functionality of MPEG-4 compliant streams to that of streams created using other proprietary applications within QuickTime and Windows Media.

 

BENEFIT TO PARTICIPANTS ATTENDING SESSION:

 

Participants will develop an appreciation for (1) how the MPEG-4 standard fits into the current streaming video environment; (2) what products are currently available to encode, transmit and decode MPEG-4 compliant media; (3) problems generally inherent in streaming digital video over the Internet, and (4) how the image quality of video streams produced by current MPEG-4 encoders compares to that of proprietary codecs such as Sorenson Video.
