Abstract
Within a regeneration device, regenerate a first input signal having a first timestamp and an inadequate signal-to-noise ratio and bypass a second input signal having a second timestamp and having an adequate signal-to-noise ratio. With a central processing server coupled to the device, obtain, from a delay tracking database, a first delay associated with a first signal path for the first input signal and a second delay associated with a second signal path for the second input signal. With the server, cause to be sent downstream the regenerated first input signal together with the first timestamp and the first delay, and the non-regenerated second input signal together with the second timestamp and the second delay.
Claims24
A method comprising:
- within a regeneration device, regenerating a first input signal having an inadequate signal-to-noise ratio, the first input signal having a first timestamp;
- within the regeneration device, bypassing a second input signal having an adequate signal-to-noise ratio, without regenerating the second input signal, the second input signal having a second timestamp;
- with a central processing server coupled to the regeneration device, obtaining, from a delay tracking database, a first delay associated with a first signal path for the first input signal and a second delay associated with a second signal path for the second input signal;
- and
- with the central processing server, causing to be sent downstream the regenerated first input signal together with the first timestamp and the first delay, and the non-regenerated second input signal together with the second timestamp and the second delay.
A system comprising:
- a regeneration device configured to regenerate a first input signal having an inadequate signal-to-noise ratio and a first timestamp and to bypass a second input signal having an adequate signal-to-noise ratio and a second timestamp, without regenerating the second input signal;
- and
- a central processing server, coupled to the regeneration device, and configured to obtain, from a delay tracking database, a first delay associated with a first signal path for the first input signal and a second delay associated with a second signal path for the second input signal, and to cause to be sent downstream the regenerated first input signal together with the first timestamp and the first delay, and the non-regenerated second input signal together with the second timestamp and the second delay.
A non-transitory computer readable medium comprising computer executable instructions which when executed by at least one processor cause the at least one processor to perform the method of:
- causing a regeneration device to regenerate a first input signal having an inadequate signal-to-noise ratio, the first input signal having a first timestamp;
- causing the regeneration device to bypass a second input signal having an adequate signal-to-noise ratio, without regenerating the second input signal, the second input signal having a second timestamp;
- obtaining, from a delay tracking database, a first delay associated with a first signal path for the first input signal and a second delay associated with a second signal path for the second input signal;
- and
- causing to be sent downstream the regenerated first input signal together with the first timestamp and the first delay, and the non-regenerated second input signal together with the second timestamp and the second delay.
