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.

A method, in a video client, for acquiring video data for output to a display of a video wall, the method comprising:
- transmitting, to a video server, a request for video frame data for a portion of a video frame, the portion of the video frame being associated with the display of the video wall;
- receiving video frame data from the video server, the received video frame data comprising data for a portion of the video frame corresponding to the request;
- transmitting, to the video server, one or more further requests for video frame data for different portions of the video frame, the different portions of the video frame being associated with the display of the video wall;
- and
- receiving further video frame data from the video server, the received further video frame data comprising data for further portions of the video frame corresponding to the one or more further requests.
