SYNCHRONIZATION OF MEDIA STREAM COMPONENTS

摘要

A method for synchronizing a plurality of components of a broadcast media stream, includes buffering streams of data samples for a plurality of components of a broadcast media stream and buffering a plurality of information packets. The stream of data samples for each of the plurality of components includes relative timing information, each information packet including timing information indicating a relationship between the relative timing information in the components and an absolute time. The method further includes performing a look-ahead action on the buffered information packets to extract timing information for each of the plurality of components; and using the extracted timing information and relative timing information to synchronize the plurality of components.
