Serialised video transmission

A viewing apparatus comprising:

• a receiver configured to receive a serialised video stream comprising a plurality of data structures, each data structure comprising an active pixel group, a source indicator assigned to the active pixel group, and a frame line position indicator assigned to the active pixel group;
• and
• one or more processors configured to:
• generate a complete line of video data by adding one or more blanking pixels to each active pixel group of a respective data structure until a next data structure comprising a next active pixel group in the serialised video stream is received;
• and
• cause the complete line of video data to be output for presentation on a display associated with the source indictor of the complete line of video data at a position in a video frame indicated by the frame line position indicator assigned to the active pixel group of the complete line of video data.

A method for combining a plurality of serialised video streams from a plurality of different video sources, each serialised video stream being received over a different communication channel, the method comprising:

• separately receiving each one of the plurality of serialised video streams;
• separately buffering at least a group of active pixels of a received frame line of a serialised frame of each of the plurality of received video streams;
• processing each buffered group of active pixels in a completely received frame line by:
• assigning a video source indicator to the buffered group of active pixels;
• and
• generating a data structure comprising the buffered group of active pixels, an indicator for the video source of the buffered group of active pixels, and a frame line position indicator for the buffered group of active pixels;
• and
• onwardly transmitting the generated data structure including the buffered group of active pixels from the frame line of the serialised frame of each of the plurality of received serialised video streams over a common channel.

A method for viewing a plurality of serialised video streams received as a single serialised video stream, the method comprising:

• receiving the serialised video stream comprising a plurality of data structures, each data structure comprising an active pixel group, a source indicator assigned to the active pixel group, and a frame line position indicator assigned to the active pixel group;
• and
• processing the received serialised video stream by:
• generating a complete line of video data by adding one or more blanking pixels to each active pixel group of a received data structure until a next data structure comprising a next active pixel group in the serialised video stream is received;
• and
• causing the complete line of video data to be output for presentation on a display associated with the source indictor of the active pixel group at a position in a video frame indicated by the frame line position indicator assigned to the active pixel group the complete line of video data.
