Abstract
A video distribution network includes a distribution plant and a first bulk encryption device connected to the distribution plant, wherein the bulk encryption device outputs a first encrypted video service stream to the distribution plant via an internet protocol (IP) interface.
Claims19
A method for performing a bulk encryption at a source center comprising:
- receiving an input transport stream;
- generating an encrypted input transport stream based on said input transport stream, wherein said encrypted input transport stream is one of an encrypted Single-Program Transport Stream output and a Multi-Program Transport Stream;
- conditioning said encrypted input transport stream for transmission through an internet protocol transport network to a destination device at an edge of said internet protocol transport network according to a configuration file;
- and
- outputting, by said source center, said encrypted input transport stream via said Single-Program Transport Stream output to said,
- wherein said edge of said internet protocol transport network bridges into a hybrid fiber-coaxial network and said source center is located away from said edge.
