Abstract: Techniques for efficient coding of video content are presented. When encoding motion vectors of a current block of a current video frame, a coder management component analyzes encoded blocks of the current frame adjacent to the current block and encoded blocks of the previous video frame that occupy locations in the previous frame corresponding to the locations of the current block and blocks adjacent to the current block. The coder management component arranges motion vectors in order as a function of spatial proximity, temporal distance between the previous frame and the current frame, and/or motion vector magnitude. The coder management component selects a coding mode, based on the order, to transmit to the decoder. A coder component encodes the current block using the motion vector associated with the coding mode.

Abstract: A method for encoding a spherical video is disclosed. The method includes mapping a frame of the spherical video to a two dimensional representation based on a projection. Further, in a prediction process the method includes determine whether at least one block associated with a prediction scheme is on a boundary of the two dimensional representation, and upon determining the at least one block associated with the prediction scheme is on the boundary, select an adjacent end block as a block including at least one pixel for use during the prediction process, the adjacent end block being associated with two or more boundaries of the two dimensional representation.
