摘要： Systems and methods are disclosed herein for correcting errors. In one embodiment, among others, a method comprises receiving a plurality of error indications from a plurality of respective receivers. The receivers are configured to receive a data stream of packets transmitted within a multicast channel. Each error indication indicates which ones of a number of the packets were not received. The method further comprises analyzing the error indications to determine a first set of receivers to which forward error correction (FEC) code is transmitted and a second set of receivers to which unicast data is transmitted.

摘要： Systems and methods for reducing multicast IP packet bandwidth in a local area network carrying Internet protocol television (IPTV) traffic are disclosed. One embodiment of a system comprises: a layer-2 switch; a slave digital home communication terminal (DHCT); and a master DHCT. The layer-2 switch has a control channel and a plurality of data ports. The slave DHCT is coupled to a first data port of the plurality. The master DHCT is coupled to the layer-2 switch control channel. The master DHCT comprises logic for requesting the layer-2 switch, over the control channel, operate in a first configuration. In the first configuration, the layer-2 switch associates a layer-2 multicast address with the first data port, examines layer-2 multicast packets, and forwards the examined layer-2 multicast packets on the first data port only if the layer-2 destination address is the first layer-2 multicast address.

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.
