System for selecting a video or audio path
View Patent ↗A communication system where an input port on a transmitter or receiver is configured to receive input data that is either audio data or video data. A processor in the transmitter or the receiver is configured to detect if the input data is either audio data or video data. The processor selects an audio path if the input data is audio data. If the input data is video data, the processor selects a video path. The selected audio path or video path sends audio output data or video output data to an output port. The output port is configured to send the audio output data or video output data.
1. A transmitter comprising:
an input port configured to receive input data comprising video data from a camera and audio data from a microphone;
a processor coupled with the input port;
a video path;
an audio path; and
an output port coupled with the video path and the audio path;
wherein the processor is configured to determine whether the input data from the input port comprises audio data or video data based on an indicator that is configured prior to receiving the input data and is separate from the input data;
wherein the processor is also configured to send the input data from the input port to the video path when the input data comprises video data, and to send the input data to the audio path when the input data comprises audio data;
wherein the output port is configured to receive video output data from the video path and audio output data from the audio path; and
wherein the output port is also configured to send the video output data or the audio output data to a receiver.
2. The transmitter of claim 1 , wherein the indicator comprises a change in a status of a switch.
3. The transmitter of claim 1 , wherein the indicator is received from a computer at a control port.
4. The transmitter of claim 1 , wherein the indicator comprises a state of a pin on the input port.
5. The transmitter of claim 1 , wherein the indicator comprises a signal from the receiver.
6. The transmitter of claim 1 , further comprising a power port wherein the processor selects an amount of power supplied to the power port based on the input data.
7. The transmitter of claim 1 , wherein the transmitter and the receiver communicate on a wireless link.
8. A receiver comprising:
an input port configured to receive input data from a transmitter comprising video data from a camera and audio data from a microphone;
a processor coupled with the input port;
a video path;
an audio path; and
an output port coupled with the video path and the audio path;
wherein the processor is configured to determine whether the input data from the input port comprises audio data or video data based on an indicator that is configured prior to receiving the input data and is separate from the input data;
wherein the processor is also configured to send the input data from the input port to the video path when the input data comprises video data, and to send the input data to the audio path when the input data comprises audio data;
wherein the output port is configured to receive video output data from the video path and audio output data from the audio path; and
wherein the output port is also configured to send the video output data or the audio output data.
9. The receiver of claim 8 , wherein the indicator comprises a change in a status of a switch.
10. The receiver of claim 8 , wherein the indicator is received from a computer at a control port.
11. The receiver of claim 8 , wherein the indicator comprises a state of a pin on the output port.
12. The receiver of claim 8 , wherein the indicator comprises a signal from the transmitter.
13. The receiver of claim 8 , further comprising a power port wherein the processor selects an amount of power supplied to the power port based on the input data.
14. The receiver of claim 8 , wherein the transmitter and the receiver communicate on a wireless link.
15. A method for sending data comprising:
receiving input data at an input port configured to receive video data from a camera and audio data from a microphone;
receiving an indicator which arrives prior to the input data and is separate from the input data;
determining whether the data from the input port comprises audio data or video data based on the indicator;
sending the input data to a video path when the input data comprises video data;
sending the input data to an audio path when the input data comprises audio data;
sending video output data from the video path to an output port when the input data comprises video data;
sending audio output data from the audio path to the output port when the input data comprises audio data;
providing the video output data from the output port when the input data comprises video data; and
providing the audio output data from the output port when the input data comprises audio data.
16. The method of claim 15 , wherein the indicator comprises a change in a status of a switch.
17. The method of claim 15 , wherein the indicator is received from a computer at a control port.
18. The method of claim 15 , wherein the indicator comprises a state of a pin on the input port.
19. The method of claim 15 , wherein the indicator comprises a signal from a transmitter.
20. The method of claim 15 , wherein the indicator comprises a signal from a receiver.
21. The method of claim 15 , further comprising selecting an amount of power supplied to a power port based in the input data.
22. The method of claim 15 , wherein providing the output data from the output port comprises providing the output data from the output port over a wireless link.
