A communication system 100 includes a content management system 221 determining a programming schedule and a video transport processing system 223 receiving a content file in forming a transport stream from the content file having a plurality of packets, each having a header with a first packet identifier in the header and a data portion. The communication system 100 further includes a content repository 274 storing the content in a satellite transport processing system 250 changing the first packet identifier to a second packet identifier in response to the programming schedule and communicating the transport stream to a user device.

1. A method comprising: determining a programming schedule;receiving a content file;forming a transport stream from the content file having a plurality of packets each having a header with a first packet identifier corresponding to a first communication means in the header;storing the content in a content repository;in response to the programming schedule, changing the first packet identifier to a second packet identifier corresponding to a second communication means; andcommunicating the transport stream to a user device using the second communication means. 2. A method as recited in claim 1 wherein determining a programming schedule is performed at a content management system. 3. A method as recited in claim 1 wherein forming a transport stream comprises forming an encrypted transport stream. 4. A method as recited in claim 1 wherein the header is unencrypted and a data portion is encrypted. 5. A method as recited in claim 1 wherein forming a transport stream comprises forming an unencrypted transport stream. 6. A method as recited in claim 1 further comprising communicating metadata to the user device. 7.

A communication system as recited in claim 26 wherein the transport stream comprises an encrypted transport stream. 28. A communication system as recited in claim 26 wherein the header is unencrypted and the data portion is encrypted. 29. A communication system as recited in claim 26 wherein the transport stream comprises an unencrypted transport stream. 30. A communication system as recited in claim 26 wherein the first packet identifier comprises a service channel identifier. 31. A communication system as recited in claim 26 wherein the transport stream comprises a first cyclic redundancy check portion and wherein the satellite transport processing system, in response to changing the first packet identifier, changes the first cyclic redundancy check portion to a second cyclic redundancy check portion. 32. A communication system as recited in claim 26 wherein the satellite transport processing system communicates the transport stream through a satellite of the satellite system. 33. A communication system as recited in claim 32 wherein the satellite transport processing system forms a header with a program map table and wherein the satellite transport processing system, prior to communicating the transport stream through the satellite, removes the program map table. 34. A communication system as recited in claim 32 wherein the transport stream comprises video. 35. A communication system as recited in claim 32 wherein the transport stream comprises audio. 36. A communication system as recited in claim 32 wherein the transport stream comprises audio and video.
