Abstract: In one embodiment, an electronic device includes a video-in interface, a video-out interface, memory circuitry, and processing circuitry. A first video stream with uncompressed frames is received via the video-in interface. The first video stream is compressed and then stored in a video buffer on the memory circuitry. For example, the uncompressed frames are individually compressed and stored in the video buffer. A second video stream with encoded frames is decoded and then played on a display device. For example, the encoded frames are decoded and then displayed on the display device via the video-out interface. The first video stream is then decompressed and played on the display device. For example, the compressed frames in the video buffer are individually decompressed and then displayed on the display device via the video-out interface.

Abstract: In one embodiment, a processing device includes a plurality of display interfaces, a plurality of display controllers, and display synchronization circuitry. The display interfaces are used to interface with a plurality of display devices, and the display controllers are used to output video frames to the display devices via the display interfaces. Moreover, the display synchronization circuitry includes a clock synchronization interface and a frame synchronization interface. The clock synchronization interface is used to synchronize a clock rate across the display controllers, while the frame synchronization interface is used to synchronize a frame rate across the display controllers.
