    Abstract: A video decoder may adaptively disable, based on a syntax element, one or more filters used for intra-prediction. In addition, the video decoder may perform intra-prediction to generate prediction data for a current block of a current video slice. Furthermore, a video encoder may adaptively disable one or more filters used for intra-prediction. Furthermore, the video encoder may signal a syntax element that controls the one or more filters. In addition, the video encoder may perform intra prediction to generate prediction data for a current video block the video data.

    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: In one example of the disclosure, a method of coding video data comprises coding video data using texture-first coding, and performing an NBDV derivation process for a block of the video data using a plurality of neighboring blocks. The NBDV derivation process comprises designating a motion vector associated with a neighboring block of the plurality of neighboring blocks coded with a block-based view synthesis prediction (BVSP) mode as an available disparity motion.

    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.

    Abstract: A video coding device performs a disparity vector derivation process for a current block of multi-view video data. The current block is in a current view. An availability value indicates that a disparity vector for the current block is unavailable when the disparity vector derivation process is unable to derive the disparity vector for the current block. When the availability value indicates that the disparity vector derivation process has not derived the disparity vector for the current block, the video coding device generates a disparity vector for the current block in another manner.
