Experimental Assessment of the Effect of Segmentation Mismatch on Continuous Media Transmission by Bluetooth
Details
This report experimentally assesses the effect of segmentation mismatch on continuous media transmission by Bluetooth. The segmentation mismatch is mainly caused by the difference between RFCOMM Maximum Frame Size and baseband packet payload size. In the experiment, a media server transfers stored video and audio streams to a single terminal with point-to-point communication; we suppose no fading environment and add white noise by which interference from DSSS systems is modeled. The experiment showed that the effect of segmentation mismatch is large especially when the total bit rate of the two streams is near the channel transmission rate. We also observed that the media synchronization control is effective in compensating for the disturbance by the segmentation mismatch in noisy environments.
