RESEARCH ON AND DESIGN OF MPEG-4 FORMAL SYNCHRONOUS DESCRIPTION INFORMATION
摘要
Abstract
It is an important direction in the multimedia field to study on synchronisation within a medium object or among several media objects. The paper briefly introduces MPEG-4 relative concepts and its architecture, welds and expands a number of conventional methods, then proposes the application of weighted directed graphs formal synchronous description method in the synchronous layer in MPEG-4 structure. Such method is more adaptive to MPEG-4 object-oriented content coding and transmission. Test results have validated the effectiveness of synchronisation achieved by weighted directed graph formal synchronous description method.关键词
