Claim 14:
15. A video-switching system in an audio video receiver (AVR) console, comprising:
a plurality of HDMI connection inputs in the AVR console for receiving video streams from a plurality of digital media sources, said HDMI connection inputs including a first HDMI input, a second HDMI input, a third HDMI input, a fourth HDMI input, a fifth HDMI input, a sixth HDMI input, a seventh HDMI input, and an eight HDMI input;
a plurality of 2:2 transceivers on one or more circuit boards in the AVR console, each having a first input, a second input, a first output, and a second output and configured to simultaneously route video streams received at either of the first and second inputs to either of the first and second outputs, said plurality of 2:2 transceivers including a first 2:2 transceiver receiving video streams from the first HDMI input and the second HDMI input, a second 2:2 transceiver receiving video streams from the third HDMI input and the fourth HDMI input, a third 2:2 transceiver receiving video streams from the fifth HDMI input and the sixth HDMI input, and a fourth 2:2 transceiver receiving video streams from the seventh HDMI input and the eight HDMI input;
a plurality of 4:1 transceivers on the one or more circuit boards in the AVR console, each having a first input, a second input, a third input, a fourth input, and one output and configured for routing video streams received at any one of the first, second, third, and fourth inputs to the one output, said plurality of 4:1 transceivers including a first 4:1 transceiver configured to receive video streams from the first output of each of the plurality of 2:2 transceivers and a second 4:1 transceiver configured to receive video streams from the second output of each of the plurality of 2:2 transceivers;
a first zone HDMI connection output in the AVR console receiving a video stream from the output of the first 4:1 transceiver to be displayed on a first digital display device located in a first zone;
a second zone HDMI connection output in the AVR console receiving a video stream from the output of the second 4:1 transceiver to be displayed on a second digital display device located in a second zone; and
a controller on the one or more circuit boards in the AVR console connected to and configured to initializing and directly control operation of each of the plurality of 2:2 transceivers and the plurality of 4:1 transceivers to simultaneously route video streams received at any of the plurality of HDMI connection inputs to any of the plurality of HDMI connection outputs by selectively enabling the inputs and the outputs of the 2:2 transceivers and 4:1 transceivers,
wherein each of the plurality of 2:2 transceivers and each of the plurality of 4:1 transceivers is an active transceiver.
