Abstract: 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.

Abstract: 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.

Abstract: A wireless communication method includes an aggregator requesting a first description substream of a multimedia service from a source over a first path, receiving confirmation that the source is available, and receiving a first substream of the service. The method includes determining if a quality of the first substream is satisfactory, and requesting to receive the multimedia service over at least one additional path from the same source. A wireless method of communication by a source device includes receiving a multimedia service request from an end device aggregator over a first path, sending an confirmation that the source is available and sending a first substream over the first path in response to the request. The method includes receiving a request to send the multimedia service over at least one additional path to the end device aggregator from the same source.

Abstract: 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.

Abstract: Television white space devices are operable to communicate information over television white space and, more specifically, to quiet a transmitter for sensing signals in the television white space. A method for inconspicuous quieting of the transmitter in a television white space device inserts, from an application layer, information into a transport stream for transmission by the transmitter of the television white space device to produce a null window of time within the transport stream at a predetermined time. The method also transmits the transport stream by the transmitter of the television white space device and quiets the transmitter during the null window of time. The method senses, by a white space sensor of the television white space device, existing signals in the white space during the null window of time.

Abstract: White space devices are operable to communicate information over white space and, more specifically, to quiet a transmitter to enable sensing signals in the white space. A method for inconspicuous quieting of a transmitter in a white space communication device modifies a transport stream for transmission by the transmitter of the white space device to provide a null window of time. The null window does not contain essential information. At least a portion of the modified transport stream is transmitted by the transmitter of the white space device. The transmitter is quieted during the null window, and white space sensing is performed during the null window.

Abstract: Mobile media server (MMS) includes MMS hosts and an MMS clients utilized for ubiquitous sharing of media content. An MMS host, which may be deployed on a mobile terminal such as a cellular telephone, can establish a logical link with an MMS client over an IP interface and initiate a streaming session with the MMS client. The MMS host may further retrieve media content from any source, such as a network source, locally stored content, or a camera and/or microphone on the MMS host, and serve the media content to the MMS client over the logical link.
