Audio control module
In embodiments of an audio control module ( 318 ), audio data ( 310 ) is received from an audio data source ( 314 ) for output to an audio rendering device ( 316 ). An initialization input ( 326 ) can be received from a wireless audio headset ( 320 ) and, responsive to receiving the initialization input, the audio data ( 328 ) is communicated to the audio headset. The audio that would be generated from the audio data ( 322 ) at the audio rendering device ( 316 ) is also limited, such as by replacing the audio data ( 322 ) with null audio data, clearing audio data packets from the audio data ( 322 ), or by asserting a mute signal ( 336 ) to the audio rendering device.
1. An audio control module, comprising:
a repeater configured to receive audio data associated with video data from a data source, the repeater further configured to route the audio data to an audio rendering device, and to route the video data and the audio data to a video rendering device;
a controller configured to process the audio data into the audio data format of the audio rendering device, and to delay the video data being routed to the video rendering device to compensate for the audio processing of the audio data, wherein the delay is set to a delay that correlates to the audio processing of the audio data to synchronize the audio generated at the audio rendering device with the video generated at the video rendering device.
2. The audio control module of claim 1 , wherein the audio control module is further configured to receive an initialization input from the audio rendering device, and the controller is configured to limit audio generated from the audio data at the video rendering device after receiving the initialization signal.
3. The audio control module of claim 2 , wherein the controller is configured to assert a mute signal to limit the audio generated at the video rendering device, replace audio data routed to the video rendering device with null audio data to limit the audio generated at the video rendering device, or clear audio packets from the audio data routed to the video rendering device to limit the audio generated at the video rendering device.
4. The audio control module of claim 1 , further comprising a wireless communications transceiver configured to route the audio data to the audio rendering device by wireless communication with the audio rendering device.
5. The audio control module of claim 4 , wherein the wireless communications transceiver wirelessly communicates with the audio rendering device using any one of Bluetooth™, Wireless Personal Area Network, or WiFi™ compliant communications.
6. The audio control module of claim 5 , wherein the audio rendering device is a Bluetooth™ headset, the controller is configured to process the audio data routed to the audio rendering device into Bluetooth-formatted audio data, and the wireless communications transceiver is a Bluetooth™ transceiver.
7. The audio control module of claim 5 , wherein the wireless communications transceiver is a WiFi™ compliant transceiver.
8. The audio control module of claim 1 , wherein at least a portion of the audio processing is performed at the audio rendering device.
9. A method, comprising:
receiving audio data associated with video data from a data source;
processing the audio data into the audio data format of an audio rendering device;
delaying video data to be routed to a video rendering device to compensate for the audio processing of the audio data, wherein the delay is set to a delay that correlates to the audio processing of the audio data to synchronize the audio generated at the audio rendering device with the video generated at the video rendering device; and
routing the audio data to the audio rendering device, and the video data and the audio data to the video rendering device.
10. The method of claim 9 , further comprising:
receiving an initialization input from the audio rendering device; and
limiting audio generated from the audio data at the video rendering device after receiving the initialization signal.
11. The method of claim 10 , further comprising:
asserting a mute signal to limit the audio generated at the video rendering device, or replacing audio data routed to the video rendering device with null audio data to limit the audio generated at the video rendering device, or clearing audio packets from the audio data routed to the video rendering device to limit the audio generated at the video rendering device.
12. The method of claim 9 , wherein routing the audio data to the audio rendering device is performed by wireless communication with the audio rendering device.
13. The method of claim 12 , wherein the wireless communication with the audio rendering device is any one of Bluetooth™, Wireless Personal Area Network, or WiFi™ compliant communications.
14. The method of claim 13 , wherein the audio rendering device is a Bluetooth™ headset, the audio data routed to the audio rendering device is processed into Bluetooth-formatted audio data, and the wireless communications with the audio rendering device are Bluetooth™ communications.
15. The method of claim 13 , wherein the wireless communications with the audio rendering device are WiFi™ compliant communications.
16. The method of claim 9 , wherein at least a portion of the audio processing is performed at the audio rendering device.
17. A system, comprising:
a data source for audio data associated with video data;
a repeater configured to receive audio data associated with video data from the data source, the repeater further configured to route the audio data to an audio rendering device, and to route the video data and the audio data to a video rendering device;
a controller configured to process the audio data into the audio data format of the audio rendering device, and to delay the video data being routed to the video rendering device to compensate for the audio processing of the audio data, wherein the delay is set to a delay that correlates to the audio processing of the audio data to synchronize the audio generated at the audio rendering device with the video generated at the video rendering device.
18. The system of claim 17 , further comprising a wireless communications transceiver configured to route the audio data to the audio rendering device by wireless communication with the audio rendering device.
19. The system of claim 18 , wherein the wireless communications transceiver wirelessly communicates with the audio rendering device using any one of Bluetooth™, Wireless Personal Area Network, or WiFi™ compliant communications.
20. The system of claim 18 , wherein the audio rendering device is a Bluetooth™ headset, the controller is configured to process the audio data routed to the audio rendering device into Bluetooth-formatted audio data, and the wireless communications transceiver is a Bluetooth™ transceiver.
