    Abstract: Methods, network devices and computer readable media are disclosed for replication and switching of Internet Protocol (IP) packets in professional media networks. In one embodiment, a method includes receiving, at a first node in a network configured for bit indexed explicit replication (BIER), and via a replication fabric within the network, a packet comprising a packet bit array. Each receiver of a plurality of non-BIER-enabled receivers reachable via the replication fabric is represented by a relative bit position in the packet bit array, and a respective IP address is assigned to each receiver. The method further includes determining that an intended non-BIER-enabled receiver of the packet is a local receiver of the first node, obtaining the IP address assigned to the local receiver, removing the packet bit array from the packet and forwarding the packet, without the packet bit array, to the local receiver via unicast IP forwarding.

    Abstract: In one embodiment, a receiver for an accelerated channel change is provided. The receiver receives a first version of a video stream for a first channel and causes display of video for the first version of the video stream for the channel. A second version of a video stream is received upon a channel change to a second channel, the second version including non-discardable pictures from the first version of the video stream. The receiver displays video for the second version of the video stream for the second channel. When a transition point is reached in the first version of the video stream for the second channel, a first version of a video stream for the second channel can be displayed.

    Abstract: Methods and network devices are disclosed for replication and switching of Internet Protocol (IP) packets in professional media networks. In one embodiment, a method includes encapsulating a unicast IP packet with a packet bit array and forwarding the encapsulated packet via a replication fabric within a network. In this embodiment, each receiver of a plurality of receivers reachable via the replication fabric is represented by a relative bit position in the packet bit array, a respective IP address is assigned to each receiver of the plurality of receivers, and the replication fabric is adapted to store disposition information mapping a relative bit position representing one or more of the plurality of receivers to IP addresses assigned to the one or more of the plurality of receivers. An embodiment of a network device includes a processor operably coupled to a network interface and adapted to perform steps of the method.
