    摘要: The present invention relates to an improved method of de-jittering MPEG-2 and MPEG-4 data that is transmitted over a network. First, a network system jitter associated with periodic reference data packets is estimated. Then, the estimated system jitter is used to adjust clock-stamped reference values in the data packets before they are provided to the PLL for clock synchronization. The invented de-jittering method improves the PLL's ability to synchronize the MPEG data and provides for a better quality playback.

    摘要: A system and method are provided for analyzing and transmitting video over a switched network. According to an aspect of the invention, two phases are generally provided: an analysis phase performed before transmission of the video; and a transmission phase performed after analyzing the video stream. During the pre-transmission video analysis phase, the video stream is analyzed in order to determine the needed traffic control parameters, such as the peak cell rate, the sustained cell rate, and the maximum burst size. The goal of the analysis phase is to select a transmission traffic contract for the encoded video stream that will minimize the utilization of network resources and permit the quality of the video to be maintained. After the analysis phase, the transmission phase is performed to transmit the video over the network in accordance with the selected traffic control parameters. During the transmission phase, a model of the decoder buffer is kept at the source and is first pre-filled by transmitting data at the sustained cell rate. Thereafter, the video stream data is transmitted at the peak cell rate or the sustained cell rate depending on the availability of tokens.
