Abstract
In one embodiment, a facilitating signal broadcasting includes receiving a first copy of a signal at a first selector of a first headend, where the first copy is received through a first receive pipe of a first ring. A second copy of the signal is received at the first selector, where the second copy is received through a second receive pipe of a second ring. The first selector selects either the first copy or the second copy. The selected copy is sent through a first transmit pipe of the first ring.
Claims16
A method for facilitating signal broadcasting, comprising:
- receiving a first copy of a signal at a first selector of a first headend, the first copy received through a first receive pipe of a first ring;
- receiving a second copy of the signal at the first selector, the second copy received through a second receive pipe of a second ring;
- selecting by the first selector either the first copy or the second copy;
- sending the selected copy through a first transmit pipe of the first ring;
- receiving the first copy of the signal at a second selector of the first headend, the first copy received through the first receive pipe of the first ring;
- receiving the second copy of the signal at the second selector, the second copy received through the second receive pipe of the second ring;
- selecting by the second selector either the first copy or the second copy;
- and
- sending the selected copy through a second transmit pipe of the second ring.
A system for facilitating signal broadcasting, comprising:
- a first selector of a first headend, the first selector operable to:
- receive a first copy of a signal, the first copy received through a first receive pipe of a first ring;
- receive a second copy of the signal, the second copy received through a second receive pipe of a second ring;
- select either the first copy or the second copy;
- a first output coupled to the first selector and operable to send the selected copy through a first transmit pipe of the first ring;
- a second selector of the first headend, the second selector operable to:
- receive the first copy of the signal, the first copy received through the first receive pipe of the first ring;
- receive the second copy of the signal, the second copy received through the second receive pipe of the second ring;
- select either the first copy or the second copy;
- and
- a second output coupled to the second selector and operable to send the selected copy through a second transmit pipe of the second ring.
Logic for facilitating signal broadcasting, the logic embodied in a non-transitory computer-readable storage medium and when executed by a computed operable to:
- receive a first copy of a signal at a first selector of a first headend, the first copy received through a first receive pipe of a first ring;
- receive a second copy of the signal at the first selector, the second copy received through a second receive pipe of a second ring;
- select by the first selector either the first copy or the second copy;
- send the selected copy through a first transmit pipe of the first ring;
- receiving the first copy of the signal at a second selector of the first headend, the first copy received through the first receive pipe of the first ring;
- receiving the second copy of the signal at the second selector, the second copy received through the second receive pipe of the second ring;
- selecting by the second selector either the first copy or the second copy;
- and
- sending the selected copy through a second transmit pipe of the second ring.
