Seamless branching
Seamless branching is a mechanism used on DVDs and Blu-ray Discs to allow the player to jump to a different scene after finishing one. The most common purpose is to have several versions of a scene within one film, without having to store the entire film on the disc several times. A popular example is the Platinum Edition DVD of The Lion King, where the user can select between the original theatrical version and an extended version. The two versions differ only in one scene (the "morning report"). The DVD player is instructed to play the film normally up to this scene, then jump to the appropriate scene as selected by the user before the commencement of the film, and then jump back to play the rest of the film.
