Abstract:
The present invention relates to a method and an apparatus for inducing motion information by using a depth information value. The present invention includes a method of allowing several blocks to share and use a specific depth information value to decrease a memory bandwidth due to approach of the depth information value when motion information is induced by using the depth information value. Thus, the present invention can reduce the memory bandwidth of coding and decoding in a video coding process.
Abstract:
In the present invention, a transmitting apparatus and method and a receiving apparatus and method for providing a 3D service are disclosed. In a transmitting method for providing a 3D service through a connection with a reference image transmitted in real time and additional image and content transmitted separately from the reference image, the transmitting method for providing the 3D service comprises: a real time reference image stream generating step of generating a real time reference image stream on the basis of a reference image and transmitting the generated image stream to a recipient in real time; and an additional image and content transmitting step of transmitting, to the recipient and separately from the reference image stream, additional images and content for providing a 3D service through a connection with the reference image. The real time reference image stream includes connection information, i.e. information related to the additional image and content to be connected to the reference image, and synchronization information for synchronizing the additional image and content with the reference image.

Abstract:
PURPOSE: An intra prediction mode decoding method and an apparatus for the same are provided to use an integrated signaling method in order to apply some of various intra prediction methods to an image selectively or altogether. CONSTITUTION: A decoding apparatus parses intra prediction mode information about a current block in a depth information map image (S1010). The decoding apparatus determines an intra prediction mode about the current block based on the intra prediction mode information (S1020). The decoding apparatus draws a final intra prediction mode about the current block by renewing the intra prediction mode according to a predetermined condition (S1030). The intra prediction mode information includes at least one of remaining intra prediction mode information and most probable mode (MPM) information.
