    摘要： Systems and methods of assembling an elementary stream from an encapsulated multimedia transport stream are disclosed. In one embodiment, the method is performed in a digital home communication terminal (DHCT). This method comprises the steps of: receiving a layer-2 packet through a binding to a network interface driver; applying at least one filter to the received packet to determine whether the received packet contains one or more multimedia transport packets meeting criteria associated with the filter; and for each multimedia transport packet meeting the applied filter criteria, copying the respective multimedia transport packet to an elementary stream buffer.

    摘要： Systems and methods are disclosed herein for requesting additional forward error correction, when needed, in a communication system. In one exemplary embodiment, among others, a method includes receiving a first set of data packets and a first amount of forward error correction (FEC) from an upstream transmitting device. The method also includes determining whether or not the first amount of FEC is sufficient to correct any detected errors with respect to the data packets. Then, an error indication is transmitted to the upstream transmitting device when the first amount of FEC is not sufficient to correct the detected errors.

    摘要： Systems and methods for providing forward error correction are disclosed in the present disclosure. In one embodiment, among others, a method comprises transmitting a stream of data packets to a receiver and transmitting a first amount of forward error correction (FEC) to the receiver. The first amount of FEC is designed to restore a first number of dropped data packets. The method also includes a receiving a message from the receiver that the first amount of FEC is not sufficient to restore a detected number of dropped data packets, and then transmitting additional FEC to restore the detected number of dropped data packets.
