摘要： Systems and methods are described for determining an optimised sampling ratio for coding video data that reduces overall distortion introduced by the coding process. It seeks to balance the information loss introduced during downsampling and the information loss introduced during coding. The sampling ratio is generally determined by reducing, or in some cases minimizing, the overall error introduced through the downsampling process and the coding process, and may be adaptive based on the content of the video data being processed and a target bit rate. Computation power can be saved by coding a downsampled video. The process derives a plurality of downsampling ratios, and selects a downsampling ratio that reduces the total amount of distortion introduced during the down - sampling and coding stages. The down - sampling ratio may be selected given the available data transmission capacity, input video signal statistics, and/or other operational parameters, and may optimally reduce the overall distortion.

摘要： Methods and systems are disclosed facilitate differentiated QoS service for packets within a single packet stream. For example, extended QCI values may be used to differentiate service of video packets associated with different priorities. A flexible representation of QoS requirements/parameters is disclosed where QoS may be defined as a hyperspace that is a function of base QoS parameters. A WTRU may explicitly specify and/or request desired QoS parameters. A WTRU may be configured to perform one or more of video packet separation into a plurality of video packet sub-streams, merging of the video packet sub-streams, and/or reordering of the packets included in the video packet sub-streams. Techniques may be utilized to exposing more information to a data transmission network regarding the type of video packets (and/or other packets) being transmitted.

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： HARQ parameters (e.g., maximum HARQ retransmission values) may be adapted. Cross-layer control and/or logical channel control may be used to select a maximum number of HARQ retransmissions, for example based on packet priority and/or QCI values. Respective priorities of video packets may be used to select one of a plurality of logical channels associated with a video application that may be established at a source wireless hop and/or a destination wireless hop. The logical channels have different HARQ characteristics. Different maximum HARQ retransmission values may be determined for select logical channels, for example such that packets of different priorities may be transmitted over different logical channels. One or more of the channels may be associated with one or more transmission queues that may have different priority designations. Video packets may be reordered (e.g., with respect to transmission order) within the transmission queues, for example in accordance with respective HARQ parameters.
