What is seamless branching?
Seamless branching allows content providers to place different versions of a program on a Blu-ray disc in a space-efficient manner. For example, on a disc with Rated and Unrated versions of a movie, the disc only contains the full Rated version of the feature plus the additional specific Unrated scenes. The player then assembles the version that the consumer selects from the disc menu. The DTS-HD Encoder includes a Seamless Branching Optimization feature to assist authoring facilities implementing this functionality.
