Claims
- 1. A method of transporting video and audio data comprising:
receiving, by a first transmitter, a video data stream; receiving, by said first transmitter, an audio data stream; generating, by said first transmitter, a composite data stream from said audio and video data streams; communicating, by said first transmitter, said composite data stream to a second transmitter; and communicating, by said second transmitter, said composite data stream to a remote receiver.
- 2. The method of claim 1, including communicating said composite data stream to said remote receiver over a digital communications link.
- 3. The method of claim 1, wherein said video data stream is a data enable signal.
- 4. The method of claim 1, wherein said audio data stream is prepended to said video data stream.
- 5. The method of claim 1, further comprising reconstructing said video and audio data streams from said composite stream.
- 6. A method of communicating data over a communications link comprising shortening a blanking period in the data to accommodate auxiliary data.
- 7. The method of claim 6, comprising modifying at least one HYSNC signal in the data to accommodate said auxiliary data.
- 8. The method of claim 6, wherein said auxiliary data is audio data.
- 9. The method of claim 6, wherein said communications link is a digital communications link.
- 10. The method of claim 6, comprising modifying a VYSNC signal in all frames in which the auxiliary data is to be transmitted.
- 11. The method of claim 10, further comprising inserting a notch in all said VYSNC signals.
- 12. The method of claim 11, wherein inserting said notch includes inserting an 8 clock cycle pulse into said VYSNC signals.
- 13. The method of claim 12, further wherein said notch is inserted into said VYSNC signals 8 clock pulses after a first edge of said VYSNC signals.
- 14. The method of claim 10, further comprising adapting at least one control signal to be compliant with a content protection standard.
- 15. The method of claim 14, wherein said at least one control signal is adapted to be compliant with said content protection standard while transmitting said auxiliary data.
- 16. The method of claim 14, wherein said control signal is ctl3.
- 17. The method of claim 14, wherein said content protection standard comprises a High-bandwidth Digital Content Protection standard.
- 18. The method of claim 14, wherein adapting said control signal comprises generating a ctl3 input using at least one VSYNC signal.
- 19. The method of claim 18, further comprising ensuring that the ctl3 input is a positive going pulse.
- 20. A system for communicating data and auxiliary data over a video communications link, comprising:
a reformatter adapted to shorten a blanking period in the data to accommodate auxiliary data, forming at least one frame; and a transmitter communicating with said reformatter and adapted to transmit said at least one frame over the communications link.
