| Abstract(in English) | This paper assesses the media synchronization quality in a Bluetooth LAN access system by experiment. We consider a situation where a server transfers stored video and audio streams to a terminal with point-to-point communication. Both FEC and ARQ are adopted as error control schemes. The slide control scheme is used for media synchronization control. We examine how the interference from DSSS systems affects the quality. For simplicity of experiment, we suppose that the Bluetooth terminal does not move while the media streams are transferred, i.e., fading does not occur. In the experiment, we evaluated several performance measures such as mean square error of intra-stream synchronization. We then found that delay jitters caused by retransmission of DM1 packets disturbed temporal relations of the streams. We also observed that the media synchronization control is effective in compensating for the disturbance. |
