Abstract:
A three-dimensional (3D) video encoding method, decoding method, and related apparatus is disclosed. The decoding method may include decoding a video bitstream to obtain a single sample flag bit corresponding to a current image block in a current depth map, performing detection on a first adjacent prediction sampling point and a second adjacent prediction sampling point of the current image block in the current depth map if the single sample flag bit obtained by decoding indicates that a decoding mode corresponding to the current image block is a single depth intra-frame mode (SDM), and constructing a sample candidate set according to results of the detection on the first adjacent prediction sampling point and the second adjacent prediction sampling point, where the sample candidate set includes a first index location and a second index location, decoding the video bitstream to obtain a single sample index flag bit corresponding to the current image block.

Claim (Index 13):
The method of  claim 7 , wherein before writing, into the video bitstream, a single sample index flag bit corresponding to the current image block, the method further comprises:\n calculating, using the depth value located in the first index location corresponding to the current image block, a first rate distortion cost corresponding to the current image block; and calculating, using the depth value located in the second index location corresponding to the current image block, a second rate distortion cost corresponding to the current image block, the first rate distortion cost being less than or equal to the second rate distortion cost, and the single sample index flag bit indicating that the prediction sample value of some or all of the pixels of the current image block is located in the first index location.
