摘要：
T Systems and methods for providing picture-in-picture, or other multi-picture displays. Some of the systems include two or more video and/or data signals that are coupled to a transmission device. In addition, a selector signal is coupled to the transmission device. The transmission device also includes a video output that, based at least in part on the selector signal, provides a derivative of one of the video and/or data signals at a first compression and bandwidth, and the other video and/or data signal at a second compression and bandwidth. Various of the methods include utilize the systems to transmit two or more video outputs based at least in part on a selector signal.
