Performance evaluation of media synchronization in PHS with the H.223 annex multiplexing protocol

This paper studies the application of a media synchronization mechanism to the interleaved transmission of video and audio specified by the H.223 annex in the Personal Handy phone System (PHS). The media synchronization problem due to network delay jitter in the interleaved transmission has not been discussed in either the annex or any related standards. The slide control scheme, which has been proposed by the authors, is applied to live media. We also propose a QOS control scheme to control both quality of the media synchronization and that of the transmission delay. Through simulation we confirm the effectiveness of the slide control scheme and the QOS control scheme in the interleaved transmission
