Method of managing display data

A system for displaying images on a shared display comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, causes the system to:
• receive a plurality of frames of image data from a plurality of originating devices, respectively, each frame of the plurality of frames including one or more compressed image data portions and respective portion metadata associated with each of the compressed image data portions, the portion metadata associated with each compressed image data portion indicating a location of the compressed image data portion in relation to the frame;
• amend the portion metadata associated with each of the compressed image data portions, without decompressing the compressed image data portions, to indicate a pixel coordinate location of the compressed image data portion in a composited image frame, the composited image frame being a composite of the plurality of frames;
• and
• transmit, to the shared display, the one or more compressed image data portions included in each of the plurality of frames and the amended portion metadata associated with each of the compressed image data portions.

A system comprising:

• a shared display;
• a plurality of originating devices configured to output a plurality of frames of image data, respectively, for display on the shared display, each frame of the plurality of frames including one or more compressed image data portions and respective portion metadata associated with each of the compressed image data portions, the portion metadata associated with each compressed image data portion indicating a location of the compressed image data portion in relation to the frame;
• and
• a compositor configured to:
• amend the portion metadata associated with each of the compressed image data portions, without decompressing the compressed image data portions, to indicate a pixel coordinate location of the compressed image data portion in a composited image frame, the composited image frame being a composite of the plurality of frames;
• and
• transmit, to the shared display, the one or more compressed image data portions included in each of the plurality of frames and the amended portion metadata associated with each of the compressed image data portions.
