Abstract
In one embodiment, a method includes receiving a program stream from a program source on a first channel. The method also includes detecting an unrecoverable error in the program stream, and receiving a standalone decodable repair stream from an error repair source on a second channel. The repair stream refers to a portion of the program stream, where the portion corresponds to the unrecoverable error. The method also includes combining the repair stream and the program stream to produce a presentable stream for user viewing.
