Abstract: Método de sincronización de flujos de datos transportados por una red de telecomunicaciones con retardos aleatorios donde se compensa, entre otros, el jitter predecible que introducirá la misma en las marcas de tiempo de un flujo de datos antes de ser transportado por ella. Así mismo, el método de sincronización de flujos incluye un filtrado de las marcas de tiempo afectadas por el jitter remanente introducido por la red (11), y que servirá para su eliminación dentro de la tolerancia preestablecida. También se mejoran los recursos de memoria del receptor, como el retardo global del sistema, y se aceleran las características de rapidez de filtrado, mediante la elección de las marcas de tiempo mas apropiadas para conseguir tal fin.

Abstract: Systems and methods are provided for signaling the decoding order of ADUs to enable efficient recovery of the decoding order of ADUs when session multiplexing is in use. A decoding order recovery process in a receiver is improved when session multiplexing is in use. For example, various embodiments improve the decoding order recovery process of SVC when no CS-DONs are utilized. First information associated with a first media sample to identify a second media sample is signaled upon packetization to indicate/aid in recovering. Upon de-packetizing, a decoding order of the first media sample and the second media sample is determined based on the received signaling of the first information.

Abstract: The present invention is suitable for use in a communications system that transmits a transport stream, such as an MPEG stream. The present invention addresses the need of generating a valid value for a duplicated packet in the transport stream. A first embodiment of the present invention interpolates between a PCR value in the original packet and the PCR value in the next PCR packet. A second embodiment of the present invention copies an original packet along with its PCR value into a duplicate packet. Subsequently, the present invention interpolates a new value for the original packet based on the original value in the duplicated PCR-bearing packet and the previous value in a PCR-bearing packet.

Abstract: A synchronization mechanism embeds synchronization triggers into a televiision signal or stream at regular intervals. The tirggers include an accurate representation of the time in which the tirggers were embedded. A receiving device (Client 315) decodes the triggers (Transport Hint Table) and sychronizes its internal timer based on the triggers. In this regard, the receiving device obtains a reference time from the internal timer and computes an offset between the reference time and the trigger time. The computed offset is then applied to the reference time. With the receipt of each new trigger, the application compares the trigger time to a new reference time with the most recently computed offset value applied. If there is any variance between these two values, the application creates a new smoothed offset.
