摘要： An apparatus, system, and method utilizing multi-description coding (MDC) for multimedia content with a plurality of forms of diversity. A source scene can be fragmented into one or more region of interest (ROI) portions and non-ROI portions, based on motion or any other metric of interest. One or more of these portions can further be fragmented by sub-sampling the respective portions to generate a plurality of lower-resolution versions, e.g., with alternating groups of pixels in respective versions. Still further, one or more of these portions can be further fragmented by image frames, e.g., with alternating frames in respective fragments. At least one ROI portion and lower-resolution versions may then be encoded into a plurality of descriptions and transmitted. Utilizing various combinations of ROI diversity, resolution diversity, and frame rate diversity can improve channel utilization and robustness for streaming multimedia content.
摘要翻译：一种利用具有多种形式的多样性的多媒体内容的多描述编码（MDC）的装置，系统和方法。基于运动或感兴趣的任何其他度量，源场景可以被分段成一个或多个感兴趣区域（ROI）部分和非ROI部分。这些部分中的一个或多个可以通过对相应部分进行子采样来进一步分段，以产生多个较低分辨率的版本，例如，在相应版本中具有交替的像素组。此外，这些部分中的一个或多个可以被图像帧进一步分段，例如，在相应片段中具有交替的帧。然后可以将至少一个ROI部分和较低分辨率版本编码为多个描述并发送。利用ROI分集，分辨率分集和帧速率分集的各种组合可以提高流媒体内容的信道利用率和鲁棒性。

摘要： 3D image data can be modified based on user preference data received from a user. The user preference data may be received at a first device and used to adjust 3D image data generated by the first device for presentation by a display device, or the first device may receive the user preference data and transmit it to a display device such that the display device may adjust the 3D image data based on the user preference data. The 3D image data may be adjusted based on user preference data to support presentation of 3D imagery on the display device in a manner desired by a user. 3D user viewing preferences may include an amount of pop-out effect in images, a stereo baseline of images, a depth range of images, a spatial distribution of images, a degree of depth sharpness in images, or specification of a user's dominant eye.

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”。然后，这些片段被用作在运动补偿处理期间而不是整个帧中生成预测帧的参考图像。

摘要： Described herein are various techniques for gathering multimedia data from one or more sources and transmiting that data over a local network to one or more devices, thereby providing ubiquitous multimedia across the network. In one configuration, a device comprising a server receives multimedia data from one or more devices on a local network, creates a multiplex signal from the various multimedia data received from the devices, and wirelessly transmits the multiplex signal over the local network. The server is further configured wherein the multiplex signal comprises a plurality of logical channels, with at least one of the logical channels representing multimedia data received from one of the devices on the network. By then tuning into one or more of the logical channels of the transmitted multiplex signal, a device on the local network can present to a user multimedia data that originates from or resides on another device on the network. According to other configurations, the multiplex signal contains not only multimedia data retrieved from devices on a local network, but can also include multimedia data that originated from sources on a wide area network, such as the Internet or a cellular telephone network.

摘要： Transmitting devices facilitate privacy protection of content broadcasted from the transmitting device to a receiving device without the need to modify the receiving device. A transmitting device may be adapted to acquire content, such as audio and/or video data, to be broadcasted by the transmitter for reception and use by a receiving device. A transmission range is selected to define a distance for broadcasting the content from the transmission device for reception and use by a receiving device. A frequency is also selected to be used for broadcasting the content. With the transmission range and frequency selected, the transmitting device may broadcast the content according to the selected transmission range and frequency.

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： A method, system, and computer program product for providing feedback over a multiple path network is provided. A first device sends a transmissions to a second device over at least two different paths of the network. Using information collected as a result of receiving the transmissions, the second device aggregates data regarding the performance of each of the paths together into a feedback message. The second device then sends this feedback message to the first device over one path of the network. The first device uses the data in the feedback message in its calculations for determining the relative performance of each path. The amount of traffic sent along each path is adjusted as appropriate, based on these calculations.
