Systems and methods for the synchronization and display of video input signals. The input signals, associated with input channels, are received by a controller. On a frame-by-frame basis, the controller controls the writing of the input signals to, and the reading of the input signals from, a memory. A frame rate control module controls frame-level synchronization between the writing operations and reading operations of the controller so that when a frame is written to the memory is not simultaneously read from the memory. The controller writes video frames for each input channel to, and reads video frames for each input channel from, the memory on a channel-by-channel basis such that the video frames corresponding to each input channel are read and written independently of one another. This allows the input signals to be unsynchronized with one another without harming the writing operations, reading operations, and display of the input signals. |
