Abstract(in English) | IP transmission has been widely deployed in broadcasting. Otherwise, it is difficult to transmit MPEG-2 Transport Stream to comply with MPEG-2 Systems requirements in which the "error of Program Clock Reference including delay jitter" should be suppressed to less than ±500ns. In this report, we illustrate reasons of the delay jitter and introduce a manner to fix this jitter by the Constant Delay Queuing (CDQ). Evaluating an experimental hub with the CDQ scheduler, it isdemonstrated that the CDQ scheduler forwards prioritized frames within jitter less than 250ns and the experimental hub enables transmission of MPEG-2 Transport Stream over IP network within the MPEG-2 Systems requirement. |
