Abstract
Methods, systems, and computer readable media can be operable to distinguish between data signals and video signals based upon interleaver depths associated with the signals. A CPE device can identify an interleaver depth associated with a signal and can make the determination that the signal is a video signal when the interleaver depth is outside of a predetermined range, the predetermined range being based on interleaver depths that are expected for a data signal.
Claims20
A method comprising:
- establishing a lock onto a first frequency associated with a first signal at a customer premise equipment device;
- determining an interleaver depth associated with the first signal;
- comparing the interleaver depth associated with the first signal to a predetermined range;
- and
- when the interleaver depth associated with the first signal is outside of the predetermined range, terminating the lock on the first frequency and establishing a lock onto a next frequency associated with a next signal.
An apparatus comprising:
- an interface configured to establish a lock onto a first frequency associated with a first signal;
- and
- one or more modules that:
- determine an interleaver depth associated with the first signal;
- compare the interleaver depth associated with the first signal to a predetermined range;
- and
- when the interleaver depth associated with the first signal is outside of the predetermined range, cause the interface to terminate the lock on the first frequency and establish a lock onto a next frequency associated with a next signal.
One or more non-transitory computer readable media having instructions operable to cause one or more processors to perform the operations comprising:
- establishing a lock onto a first frequency associated with a first signal at a customer premise equipment device;
- determining an interleaver depth associated with the first signal;
- comparing the interleaver depth associated with the first signal to a predetermined range;
- and
- when the interleaver depth associated with the first signal is outside of the predetermined range, terminating the lock on the first frequency and establishing a lock onto a next frequency associated with a next signal.
