摘要： This disclosure relates to techniques to establish a multicast communication session between a source device and multiple sink devices in a Wireless Display (WD) system. Two or more sink devices may be interested in receiving the same media data from the source device. According to the techniques, the source device establishes a multicast session with the sink devices in the WD system, and sends a single copy of multicast media data for the multicast session to the interested sink devices using a receiving multicast port. The source device selects a receiving multicast port number as a destination identifier for each multicast session. The sink devices interested in receiving the media data of a given multicast session bind on the receiving multicast port for the multicast session. This disclosure describes several exemplary multicast subscription procedures to ensure correct binding on the receiving multicast port at each of the sink devices.

摘要： An end-to-end multimedia streaming system can include a streaming server and a destination. The streaming server includes a content source, which sends multiple description coding-encoded content over a plurality of paths to the destination. The destination includes an aggregator for aggregating the descriptions from the multiple paths, decoding and recombining them to recover the content. A feedback sender at the destination generates traffic performance variables based on the channel conditions of the multiple paths, and sends these variables to a feedback receiver at the streaming server. The feedback receiver utilizes the feedback information to make adjustments to the transmissions of the content, and to synchronize the transmissions over the multiple paths.

摘要： In general, techniques are described for providing a multimedia management system to facilitate multimedia content mobility. More specifically, an apparatus may implement the techniques. The apparatus may comprise one or more wireless modems and a control unit. The one or more wireless modems receive multimedia content in a first format from a first application over a wireless communication channel. The control unit includes a Multimedia Management System (MMS) that configures the control unit to provide a multimedia bridge between the first format and a second format, where the second format is supported by a second application. The configured multimedia bridge transforms the multimedia content from the first format to the second format concurrent to the one or more wireless modems receiving a portion of the multimedia content.

摘要： In general, this disclosure describes techniques for encoding and decoding sequences of video frames using fragmentary reference pictures. The disclosure presents video encoding and decoding techniques for modified temporal compression based on fragmented references rather than complete reference pictures. In a typical sequence of video frames, only a portion (i.e., a tile) of each frame includes moving objects. Moreover, in each frame, the moving objects tend to be confined to specific areas that are common among each frame in the sequence of video frames. As described herein, such common areas of motion are identified. Pictures are then extracted from the identified areas of the video frames. Because these pictures may represent only portions of the frames, this disclosure refers to these pictures as "fragments." It is then these fragments that are used as reference pictures for generating predicted frames during a motion compensation process, rather than the entire frame.
摘要翻译：通常，本公开描述了使用片段参考图片对视频帧的序列进行编码和解码的技术。本公开提供了基于分段参考而不是完整参考图片的用于修改的时间压缩的视频编码和解码技术。在典型的视频帧序列中，每个帧的仅一部分（即瓦片）包括运动对象。此外，在每个帧中，移动对象倾向于被限制在视频帧序列中的每个帧中共同的特定区域。如本文所述，识别这样的公共运动区域。然后从视频帧的识别区域中提取图像。因为这些图片可以仅表示帧的一部分，所以本公开将这些图片称为“片段”。那么这些片段被用作用于在运动补偿过程期间生成预测帧而不是整个帧的参考图像。
