Adaptive transmission control for error-resilient multimedia synchronization

Multimedia streams impose tight temporal constraints since different kinds of continuous multimedia streams have to be played synchronously. We devise in this paper a adaptive transmission scheme to ensure the error-resilient and synchronous playback of audio and video streams based on the real-time transport protocol. Realization of our adaptive transmission control is composed of a series of operations in three stages, namely, (1) dynamic reordering mechanism, (2) error-resilient mechanism, and (3) adaptive synchronization mechanism. In this paper, an empirical study is conducted to provide insight into our adaptive transmission scheme. As validated by our performance study, the adaptive transmission mechanism is able to strike a good balance of both stable playback and the end-to-end delay reduction. Furthermore, we analyze the jitter resistance, the end-to-end delay, and video quality in order to enhance the applicability of this scheme to more applications that require the transmission of multimedia data.
