摘要： Visual information may be delivered to streaming-capable devices in a viewing environment, such as a home environment or a commercial environment. The visual information can be adapted to user behavior and/or viewing conditions in such a way as to deliver a satisfactory user experience while conserving network resources, such as bandwidth and/or capacity. Viewing distance and/or ambient light, which may affect viewing conditions in a viewing environment, may be estimated. Bandwidth may be reduced by eliminating details that may not be perceived by the user in the estimated viewing conditions (e.g., by determining a spatial resolution (e.g. a maximum spatial resolution) perceptible under the viewing conditions and not exceeding that spatial resolution).

摘要： Intra planar approach(es) may be used to predict a pixel(s) in a current block. The current block may be associated with a reconstructed left reference line, a reconstructed top reference line, and an non-reconstructed reference line to be predicted. The reconstructed reference lines may have been decoded and may be available. The non-reconstructed reference lines to be predicted may include an non-reconstructed right and/or an non-reconstructed bottom reference lines. A pivot reference pixel may be identified and may be located on an extension of the reconstructed left and/or top reference lines. A reference pixel may be determined and may be located on the reconstructed top and/or left reference lines. Pixels on the non-reconstructed reference line(s) may be predicted based on the pivot reference pixel and the reference pixel. Pixels of the current block may be predicted using the predicted pixels on the right and the bottom reference lines.

摘要： Quality-based optimizations of a delivery process of streaming content may be enabled. The optimization may take the form of quality-based switching. To enable quality-based switching in a streaming client, the client may have access to information about the quality of an encoded segment and/or sub-segment. Quality-related information may include any number of added quality metrics relating to an encoded segment and/or sub-segment of an encoded video stream. The addition of quality-related information may be accomplished by including the quality-related information in a manifest file, including the quality-related information in segment indices stored in a segment index file, and/or providing additional files with quality-related segment information and providing a link to the information from an MPD file. Upon receiving the quality-related information, the client may request and receive a stream that has a lower bitrate, thereby saving bandwidth while retaining quality of the streaming content.

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： Systems, methods and instrumentalities are disclosed for adaptively selecting an adaptive loop filter (ALF) procedure for a frame based on which temporal layer the frame is in. ALF procedures may vary in computational complexity. One or more frames including the current frame may be in a temporal layer of a coding scheme. The decoder may determine the current frame's temporal layer level within the coding scheme. The decoder may select an ALF procedure based on the current frame's temporal layer level. If the current frame's temporal layer level is higher within the coding scheme than some other temporal layer levels, an ALF procedure that is less computationally complex may be selected for the current frame. Then the decoder may perform the selected ALF procedure on the current frame.

摘要： A video encoding device (e.g., a wireless transmit/receive unit (WTRU)) may transmit an encoded frame with a frame sequence number using a transmission protocol. The video encoding device, an application on the video encoding device, and/or a protocol layer on the encoding device may detect a packet loss by receiving an error notification. The packet loss may be detected at the MAC layer. The packet loss may be signaled using spoofed packets, such as a spoofed NACK packet, a spoofed XR packet, or a spoofed ACK packet. A lost packet may be retransmitted at the MAC layer (e.g., by the encoding device or another device on the wireless path). Packet loss detection may be performed in uplink operations and/or downlink operations, and/or may be performed in video gaining applications via the cloud. The video encoding device may generate and send a second encoded frame based on the error notification.
