Abstract: Various embodiments of methods and systems for balancing user experience in a multimedia conferencing community are disclosed. An exemplary embodiment envisions a portable computing device (“PCD”) receiving data indicative of one or more visual multimedia parameter settings in a companion PCD of the community. Based on the received data, the PCD may determine an adjustment to the settings of one or more of its own visual multimedia parameters such that a multimedia output in the form of a data packet stream is adjusted. In this way, the PCD may conserve power consumption by avoiding unnecessary multimedia workload processing for encoding a multimedia output that would not benefit the quality of service (“QoS”) delivered by the companion PCD. Additionally, by optimizing the quality of the multimedia output in view of the companion device parameter settings, the PCD may allocate more of its power budget to improving its own QoS level.

Abstract: A video coder searches a set of neighbor blocks to generate a plurality of disparity vector candidates. Each of the neighbor blocks is a spatial or temporal neighbor of a current block. The video coder determines, based at least in part on the plurality of disparity vector candidates, a final disparity vector for the current block.

Abstract: When coding multiview video data, a video encoder and video decoder may select a candidate picture from one of one or more random access point view component (RAPVC) pictures and one or more pictures having a lowest temporal identification value. The video encoder and video decoder may determine whether a block in the selected candidate picture is inter-predicted with a disparity motion vector and determine a disparity vector for a current block of a current picture based on the disparity motion vector. The video encoder and video decoder may inter-prediction encode or decode, respectively, the current block based on the determined disparity vector.

Abstract: In general, the disclosure relates to encoding and decoding a block of video data associated with three-dimensional (3D) video. A video coding device determines whether a depth condition associated with the block of video data should be set to valid within a coded bitstream. When the depth condition should be set to valid, the video coding device sets the depth condition to valid and encodes the block of video data using at least one camera parameter. The video coding device then determines whether the depth condition is valid. When the depth condition is valid, the video coding device decodes the block of video data using at least one camera parameter.

Abstract: A video decoder performs a neighboring-block based disparity vector (NBDV) derivation process to determine a disparity vector or performs a NBDV refinement (NBDV-R) process to determine the disparity vector. The video decoder uses the disparity vector as a disparity vector for a current block without using a median filtering process on multiple disparity motion vectors, wherein the current block is coded in either a skip mode or a direct mode. Furthermore, the video coder determines pixel values for the current block.
