Abstract: Inter-layer motion mapping information may be used to enable temporal motion vector prediction (TMVP) of an enhancement layer of a bitstream. For example, a reference picture and a motion vector (MV) of an inter-layer video block may be determined. The reference picture may be determined based on a collocated base layer video block. For example, the reference picture may be a collocated inter-layer reference picture of the reference picture of the collocated base layer video block. The MV may be determined based on a MV of the collocated base layer video block. For example, the MV may be determined by determining the MV of the collocated base layer video block and scaling the MV of the collocated base layer video block according to a spatial ratio between the base layer and the enhancement layer. TMVP may be performed on the enhancement layer picture using the MV of the inter-layer video block.

Abstract: Methods and apparatus may be used to signal slice skip mode of a multiple layer scalable coding system. A correlation between the corresponding regions of video signals in multiple layers and inter-layer processing techniques may make it possible to infer a slice or picture in the enhancement layer from the corresponding region in a base layer picture. Accordingly, a video stream may be encoded to indicate that an enhancement layer slice or picture may be skipped.

Abstract: Embodiments include processes, systems, and devices that allow a white space base station to request available frequency ranges for white space transmission in a local area. A white space finder service models a primary user device's transmission signal propagation area using terrain data associated with the local area of the primary user device. The white space finder service also determines, based on the location of the white space base station and the modeled propagation area, one or more locally available, non-interfering frequency ranges and provides them to the white space base station. The white space base station compares the provided frequency ranges to policies and selects one or more of the available frequencies that accommodate the policies. The white space base station also maps the transmission frequency ranges to virtual frequency ranges for transmission by a software-defined radio employing spectrum virtualization.

Abstract: 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.

Abstract: 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.

Abstract: Signaling of layer dependency and/or priority of dependent layers in a video parameter set (VPS) may be used to indicate the relationship between an enhancement layer and its dependent layers, and/or prioritize the order of the dependent layers for multiple layer scalable video coding of HEVC for inter-layer prediction. A method may include receiving a bit stream that includes a video parameter set (VPS). The VPS may include a dependent layer parameter that indicates a dependent layer for an enhancement layer of the bit stream. The dependent layer parameter may indicate a layer identification (ID) of the dependent layer. The VPS may indicate a total number of dependent layers for the enhancement layer. The VPS may include a maximum number of layers parameter that indicates a total number of layers of the bit stream. The total number of dependent layers for the enhancement layer may not include the enhancement layer.

Abstract: 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).
