The Jitter Delay Guarantees by Buffer Control in Multimedia Environments

Abstract

In applications of multimedia networks, Transmissions involving data, audio, graphics, video, images, and animation are provided. The QoS (quality of service) guarantees the above medias are stringent topics. A good QoS has the ability to reserve resources within network and terminal devices to ensure that certain perceptual performance measures are meet. For QoS guarantee, the technique by using buffer compensation is necessary. The decision problem about how large the buffer size for selections is an interesting issue. At this paper we are concentrating on the compensation of jitter delay at the destination by using buffer control. If the buffer size is too large, the system resources are wasting, in another aspect, too short buffer will not guarantee the system performance requirements. In this paper our propose an simple formula on calculating an adequate buffer size for delay jitter control at the destination node by Chernoff bound methods, the jitter is properly controlled without wasting too much unnecessary resources and the performance is guaranteed in the real time multimedia environments.
