    摘要： A decoding complexity may be used to predict power consumption for receiving, decoding, and/or displaying multimedia content at a wireless transmit/receive unit (WTRU). The decoding complexity may be based on decoding complexity feedback received from a reference device, such as another WTRU. The decoding complexity feedback may be based on measurements performed at the reference device for receiving decoding, and/or displaying the multimedia content. A content providing device may indicate the decoding complexity of requested media content to a WTRU, or another network entity. The decoding complexity may be indicated in a streaming protocol or file associated with the media content. The WTRU, or other network entity, may use the decoding complexity determine its preferences regarding transmission of the media content. The content providing device may determine whether to transmit the media content based on the decoding complexity and/or the preferences of the WTRU or other network entity.

    摘要： A method and apparatus for providing smooth stream switching in video and/or audio encoding and decoding may be provided. Smooth stream switching may include the generation and/or display of one or more transition frames that may be utilized between streams of media content encoded at different rates. The transition frames may be generated via crossfading and overlapping, crossfading and transcoding, post-processing techniques using filtering, post-processing techniques using re-quantization, etc. Smooth stream switching may include receiving a first data stream of media content characterized by a first signal-to-noise ratio (SNR) and a second data stream of the media content characterized by a second SNR. Transition frames may be generated using at least one of frames of the first data stream and frames of the second data stream. The transition frames may be characterized by one or more SNR values that are between the first SNR and the second SNR.

    摘要： Described herein are methods and systems associated with viewing condition adaption of multimedia content. A method for receiving multimedia content with a device from a network may include determining a viewing parameter, transmitting a request for the multimedia content to the network, whereby the request may be based on the viewing parameter, and receiving the multimedia content from the network, whereby the multimedia content may be processed at a rate according to the viewing parameter. The viewing parameter may include at least one of: a user viewing parameter, a device viewing parameter, or a content viewing parameter. The method may further include receiving a multimedia presentation description (MPD) file from the network. The MPD file may include information relating to the rate of the multimedia content and information relating to the rate may include a descriptor relating to the viewing parameter, whereby the descriptor may be required or optional.

    摘要： Systems, methods, and instrumentalities are disclosed for client centric service quality control. A first viewport of a 360 degree video may be determined. The 360 degree video may comprise one or more of an equirectangular, a cube-map, a cylindrical, a pyramidal, and/or a spherical projection mapping. The first viewport may be associated with a spatial region of the 360 degree video. An adjacent area that extends around the spatial region may be determined. A second viewport of the 360 degree video may be determined. A bitstream associated with the 360 degree video may be received. One or more enhanced regions may be included in the bitstream. The one or more enhanced regions may correspond to the first and/or second viewport, A high coding bitrate may be associated with the first viewport and/or the second viewport.
