    摘要: Systems, methods, and instrumentalities are provided to implement video coding system (VCS). The VCS may be configured to receive a video signal, which may include one or more layers (e.g., a base layer (BL) and/or one or more enhancement layers (ELs)). The VCS may be configured to process a BL picture into an inter-layer reference (ILR) picture, e.g., using picture level inter-layer prediction process. The VCS may be configured to select one or both of the processed ILR picture or an enhancement layer (EL) reference picture. The selected reference picture(s) may comprise one of the EL reference picture, or the ILR picture. The VCS may be configured to predict a current EL picture using one or more of the selected ILR picture or the EL reference picture. The VCS may be configured to store the processed ILR picture in an EL decoded picture buffer (DPB).

    摘要: Priority information may be used to distinguish between different types of video data, such as different video packets or video frames. The different types of video data may be included in the same temporal level and/or different temporal levels in a hierarchical structure. A different priority level may be determined for different types of video data at the encoder and may be indicated to other processing modules at the encoder, or to the decoder, or other network entities such as a router or a gateway. The priority level may be indicated in a header of a video packet or signaling protocol. The priority level may be determined explicitly or implicitly. The priority level may be indicated relative to another priority or using a priority identifier that indicates the priority level.

    摘要: Methods and systems are disclosed for a mobile device to decode video based on available power and/or energy. For example, the mobile device may receive a media description file (MDF) from for a video stream from a video server. The MDF may include complexity information associated with a plurality of video segments. The complexity information may be related to the amount of processing power to be utilized for decoding the segment at the mobile device. The mobile device may determine at least one power metric for the mobile device. The mobile device may determine a first complexity level to be requested for a first video segment based on the complexity information from the MDF and the power metric. The mobile device may dynamically alter the decoding process to save energy based on the detected power/energy level.
