Abstract: Aspects of the present disclosure relate to a method, in a video output device, for acquiring video data for outputting to a display. The method comprises subscribing to a multicast stream of a plurality of multicast streams. Each multicast stream is streamed from a video source and comprises video frame data corresponding to a portion of a video frame. The multicast stream to which the video output device subscribes comprises video frame data that is for display on a display associated with the video output device. The method then comprises receiving the video frame data that is for display on the display.

Abstract: Systems, devices, and methods according to the present disclosure can include a backplane device for exchanging audio information, video information, or other data among multiple audio, video, and/or data (AVD) processing or storage hardware modules. The backplane device includes a group of AVD module slots, and each of the module slots can receive an AVD processing hardware module, an AVD storage hardware module, or other signal processing hardware module. The backplane device includes a serial bus communication loop to couple each of the AVD module slots. The serial bus communication loop is maintained even when an AVD module slot of the backplane device is unoccupied by a hardware module. In an example, multiple backplane devices according to the present disclosure can be daisy-chained together, and packetized information can be exchanged among modules in any of the multiple backplane devices using the communication loop.
