Claim One:
1. A method for transmitting view components for three-dimensional (3D) views, the method comprising: generating one or more texture components and one or more depth map components; generating a first supplemental enhancement information (SEI) message including a 3D hierarchy information element configured to signal hierarchy information related to coding between the one or more texture components and the one or more depth map components; generating a second SEI message including a gradual view refresh (GVR) information element configured to signal information related to view component recovery by using a random access point; generating a first network abstraction layer (NAL) unit including the first SEI message including the 3D hierarchy information element; generating a second NAL unit including the second SEI message including the GVR information element; and generating a broadcast signal including the one or more texture components, the one or more depth map components, the first NAL unit, and the second NAL unit, wherein the GVR information element comprises a 3D extended view number information indicating a number of view components required to acquire a complete view component.
