System, method and apparatus for connecting multiple audio/video sources to an audio/video sink

A transmitter unit comprising:

• a first interface configured to receive from a first audio/video source a first input signal having a first signal format;
• a second interface configured to receive from a second audio/video source a second input signal having a second signal format, wherein the second signal format is different than the first signal format;
• switching logic configured to selectively convert either the first input signal or the second input signal from its respective signal format to a common signal format;
• and
• a third interface configured to wirelessly transmit the converted signal to a receiver unit connected to an audio/video sink.

An audio/video switching system comprising:

• a first transmitter unit configured to receive a first plurality of input signals from a corresponding first plurality of audio/video sources and to selectively convert one of the first plurality of input signals into a format suitable for transmission over a first wireless link;
• a second transmitter unit configured to receive a second plurality of input signals from a corresponding second plurality of audio/video sources and to selectively convert one of the second plurality of input signals into a format suitable for transmission over a second wireless link;
• and
• a receiver unit configured to selectively receive either a signal transmitted from the first transmitter unit over the first wireless link or a signal transmitted from the second transmitter unit over the second wireless link and to convert the received signal into a format suitable for wired transmission to an audio/video sink.
