Abstract

A video/audio system includes an interface device (28) that receives a plurality of audio and video signals from a plurality of sources (35, 25, 22). The interface device combines these signals into various combinations and transmits the combinations to a receiver (75). The receiver is configured to interface one of the combinations of signals with a user. In this regard, the receiver (75) allows the user to select one of the combinations, and in response, the receiver separates the video signal(s) of the selected combination from the audio signal(s) of the selected combination. Then, the receiver (75) renders the video signal(s) via a display device and produces a sound defined by the audio signal(s) via a speaker. Accordingly, the user is able to control which set of audio and video signals are interfaced with the user.

Claims (23)

1. A system (20) for enabling spectators at a stadium to selectively view different images of an event occurring at said stadium and to hear different sounds associated with said event, comprising:
a plurality of audio combiners (52), said audio combiners (52) configured to receive a plurality of audio signals generated from different audio sources at said stadium and to combine said audio signals into combined signals having different combinations of said audio signals;
a plurality of signal modulators (61), said signal modulators (61) configured to receive a plurality of video signals from different video sources at said stadium, said signal modulators (61) further configured to receive said combined signals from said audio combiners (52) and to combine and modulate said received video signals and combined signals into modulated signals having different combinations of said video and audio signals; and a signal combiner (67) configured to receive said modulated signals from said signal modulators (61) and to combine said modulated signals into a multiplexed signal, said signal combiner (67) further configured to transmit said multiplexed signal to receiver (75) associated with said spectators.
2. The system (20) of claim 1, wherein at least one of said audio signals is combined by each of said audio combiners (52).
3. The system (20) of claim 1, wherein each of said receivers (75) is configured to receive said multiplexed signal, to demultiplex said multiplexed signal, to receive inputs from one of said spectators, to select at least one of said video signals and one of said combined signals based on said inputs, to render said one video signal, and to produce sounds based on said one audio signal.
4. The system (20) of claim 3, wherein said each receiver (75) includes a head mounted display (151) to render said one video signal.
5. The system (20) of claim 3, further comprising:

a signal separator configured to receive a combined signal, to separate one of said audio signals from said combined signal, to separate one of said video signals from said combined signal, to transmit said separated audio signal to one of said audio combiners (52), and to transmit said separated video signal to one of said signal modulators (61).
6. A method for enabling spectators at a stadium to selectively view different images of an event occurring at said stadium and to hear different sounds associated with said event, comprising the steps of:
