Abstract
In some embodiments, a spatially multiplexed output decoder may spatially multiplex video packets received in a time multiplexed video stream. A video stream with video packets from two or more sources may be received along with metadata. In some embodiments, a decoder may organize the video packets into respective buffers (e.g., each buffer including video packets for a respective video image). The spatially multiplexed output decoder may spatially multiplex the video images (which are made up of data from the respective video packets) into a video frame to be outputted (e.g., to a separate buffer). The video images in the video frame may then be demultiplexed in other parts of the system (e.g., in a virtual decoder) using information provided about the video frame (e.g., in metadata formed with the video frame).
