Multicast video advertisement insertion using routing protocols

摘要

First video material is transmitted from a video source, over a video content network, to consumer premises equipment, via a hub router. The video source has a source address and there is a first path length between the hub router and the video source. Upon occurrence of a first triggering condition, a short route metric is announced from a supplemental video material server coupled to the hub router. The short route metric causes the hub router to perceive a second path length, between the hub router and the supplemental video material server, as shorter than the first path length. The supplemental video material server has a source address identical to the source address of the video source. Thus, the consumer premises equipment obtains supplemental video material from the supplemental video material server instead of first video material from the video source. Aspects of a system and a supplemental video material server are also disclosed.

主权项

1. A method comprising the steps of:
transmitting a signal including first video material, from a video source, over a video content network, to consumer premises equipment, via a hub router, wherein said video source has a source address and wherein there is a first path length between said hub router and said video source; and controlling, by a supplemental video material server coupled to said hub router, an insertion of supplemental video material into said signal obtained by said consumer premises equipment upon occurrence of a first triggering condition by announcing a short route metric from said supplemental video material server, said short route metric which causes said hub router to perceive a second path length, between said hub router and said supplemental video material server, as shorter than said first path length, said supplemental video material server having a source address identical to said source address of said video source, such that said consumer premises equipment obtains said supplemental video material from said supplemental video material server instead of said first video material from said video source.
