摘要： A system and method for improved performance by a DVB-H receiver is described that allows good Internet Protocol (IP) packets in a Multiprotocol Encapsulation-Forward Error Correction (MPE-FEC) frame to be salvaged even when there are other IP packets in the frame that may have bytes in error after the performance of MPE-FEC operations. To achieve this, the system and method provides a means for ascertaining where IP packets loaded into a memory begin and end in a manner that can be relied upon even when individual bytes of the IP packets, such as certain bytes of the IP packet header used to determine total packet length, may be in error.

摘要： A hardware-implemented video broadcasting receiver is described. The hardware-implemented video broadcasting receiver includes a radio frequency (RF) tuner, a demodulator connected to the RF tuner, link layer logic connected to the demodulator, and a power manager connected to the RF tuner, the demodulator and the link layer logic. The power manager is configured to receive delta-T values extracted from a transport stream by the link layer logic, to determine whether each of the RF tuner, the demodulator and the link layer logic can be powered down based on the delta-T values, and to power down the RF tuner, the demodulator and the link layer logic based on the determination, thereby reducing the average power consumed by the video broadcasting receiver.
