Abstract
In response to a video aspect ratio of a frame of video not matching an aspect ratio of a display panel of a display device, a source device of a processing system transmits only the frame to the display device and metadata indicating that the display device is to generate bars for letterboxing or pillarboxing. By generating the bars for letterboxing or pillarboxing at the display device instead of transmitting the bars from the source device to the display device or storing the bars at a frame buffer of the display device, the processing system conserves power and bandwidth.
