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.
A view component receiving device for three-dimensional (3D) views, the view component receiving device comprising:
- a tuner configured to receive a broadcast signal including one or more texture components, the one or more depth map components, and network abstraction layer (NAL) units;
- a demultiplexer configured to parse the NAL units including 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, and 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 from the broadcast signal;
- and
- a view component decoder configured to decode the one or more texture components and the one or more depth map components by using the 3D hierarchy information element included in the first SEI message and the second SEI message,
- 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, and
- wherein the view component decoder further uses the GVR information element, so as to decode the one or more texture components and the one or more depth map components.
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 3D hierarchy information descriptor configured to signal hierarchy information related to coding between the one or more texture components and the one or more depth map components, wherein the 3D hierarchy information descriptor comprises hierarchy view type information identifying whether a specific view component corresponds to a texture component or to a depth map component, and embedded hierarchy view number information indicating a number of view components that are required to be decoded before decoding the specific view component;
- and
- generating a broadcast signal including the one or more texture components, the one or more depth map components, and the 3D hierarchy information descriptor,
- wherein the broadcast signal further includes a gradual view refresh (GVR) information element configured to signal information related to view component recovery by using a random access point, and
- 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.
