The device profile received from the first wireless mobile communications device and media content may be sent to a server communicatively coupled to the network at a second geographic location. Media content may be received from the server, where the media content has been reformatted based on the device profile. The reformatted media content may be transmitted to the first wireless mobile communications device. The received device profile of the first wireless mobile communication device may be stored. | 03-29-2012 |
20130050423 | METHOD AND SYSTEM FOR RESPONSE TIME COMPENSATION FOR 3D VIDEO PROCESSING - An interleaved multi-view video stream is received. The interleaved multi-view video stream includes one or more first view frames, one or more second view frames, and blanking frames in a sequential pattern. The blanking frames separate the first view frames from the second view frames in the sequential pattern. The interleaved multi-view video stream is displayed in the sequential pattern. In one embodiment, the blanking frames are detected, and operation of a viewing device is synchronized based at least in part on the blanking frames being detected. | 02-28-2013 |
20130151727 | MEDIA PROCESSING SYSTEM SUPPORTING DIFFERENT MEDIA FORMATS VIA SERVER-BASED TRANSCODING - Systems and methods that reformat media are described. In one embodiment, a system may include, for example, a server, a first communications device and a second communications device. The server, the first communications device and the second communications device may be operatively coupled to a network. The second communications device may receive, from the first communications device, a device profile relating to the first communications device and may send the device profile and media content to the server. The server may reformat the media content based on the device | 06-13-2013 |
20130235157 | METHOD AND SYSTEM FOR FRAME BUFFER COMPRESSION AND MEMORY RESOURCE REDUCTION FOR 3D VIDEO - A video receiver receives a compressed 3D video comprising a base view video and a residual view video from a video transmitter. The video receiver decodes the received base view video and an enhancement view video of the received compressed 3D video into a left view video and a right view video. Base view pictures are generated selectively based on available memory resource. The residual view video is generated by subtracting base view pictures from corresponding enhancement view pictures. The received base view and residual view videos are buffered for video decoding. Pictures in the buffered residual view video are added to corresponding pictures in the buffered base view video for enhancement view decoding. The left view video and/or the right view video are generated from the resulting decoded base view and enhancement view pictures. A motion vector used for a disparity predicted macroblock is applied to adjacent macroblock pre-fetching. | 09-12-2013 |
20130254821 | Method and System for Providing Complete Internet Anywhere with Partial Server Processing - Methods and systems are described for providing complete Internet anywhere with partial server processing in which a request is sent from a set-top-box (STB) to a server communicatively coupled with the STB to process a portion of a web page that is unsupported by a web browser running on the STB. In one such method, the STB sends to the server an unsupported content request associated with a portion of a web page that is unsupported by a web browser executing on the STB. The STB receives a data stream from the server in response to the unsupported content request. The data stream was generated at the server by processing the unsupported portion of the web page. The STB composites the received data stream with another portion of the web page, that is supported by the web browser, to produce the web page. | 09-26-2013 |
20130272433 | ERROR CONCEALMENT FOR MPEG DECODING WITH PERSONAL VIDEO RECORDING FUNCTIONALITY - Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. Error concealment of MPEG data may take place within various components within playback, recording, reading and writing data systems. The error concealment may be provided within existing systems whose components may not be capable of accommodating errors within MPEG data. In certain embodiments, the available data that contain no errors is maximized to conceal those portions of the data that do include errors. | 10-17-2013 |
20130272566 | Method and System for Watermarking 3D Content - A video transmitter identifies regions in pictures in a compressed three-dimensional (3D) video comprising a base view video and an enhancement view video. The identified regions are not referenced by other pictures in the compressed 3D video. The identified regions are watermarked. Pictures such as a high layer picture in the base view video and the enhancement view video are identified for watermarking. The identified regions in the base view and/or enhancement view videos are watermarked and multiplexed into a transport stream for transmission. An intended video receiver extracts the base view video, the enhancement view video and corresponding watermark data from the received transport stream. The corresponding extracted watermark data are synchronized with the extracted base view video and the extracted enhancement view video, respectively, for watermark insertion. The resulting base view and enhancement view videos are decoded into a left view video and a right view video, respectively. | 10-17-2013 |
20130298152 | Supporting multiple users from a single location sharing a media processing system via a personal media guide - Systems and methods of supporting multiple users from a single location sharing a media processing system via a personal media guide are provided. In one embodiment, a system may comprise, for example, a communication device, media content, and a software platform. The communication device may be coupled to a communication network. The media content may be disposed in the communication network or the communication device, and the media content may comprise broadcast media and personal media. The software platform may reside on the communication device, and the software platform may further receive authentication information and facilitate a display of a user-defined selection from the media content by the communication device in a user-defined layout. | 11-07-2013 |
20140137175 | METHOD AND SYSTEM FOR PROVIDING COMPLETE INTERNET ANYWHERE WITH PARTIAL SERVER PROCESSING - Methods and systems are described for providing complete Internet anywhere with partial server processing in which a request is sent from a set-top-box (STB) to a server communicatively coupled with the STB to process a portion of a web page that is unsupported by a web browser running on the STB. In one such method, the STB sends to the server an unsupported content request associated with a portion of a web page that is unsupported by a web browser executing on the STB. The STB receives a data stream from the server in response to the unsupported content request. The data stream was generated at the server by processing the unsupported portion of the web page. The STB composites the received data stream with another portion of the web page, that is supported by the web browser, to produce the web page. | 05-15-2014 |
20150015671 | METHOD AND SYSTEM FOR ADAPTIVE VIEWPORT FOR A MOBILE DEVICE BASED ON VIEWING ANGLE - A 2D and/or 3D video processing device comprising a camera and a display captures images of a viewer as the viewer observes displayed 2D and/or 3D video content in a viewport. Face and/or eye tracking of viewer images is utilized to generate a different viewport. Current and different viewports may comprise 2D and/or 3D video content from a single source or from different sources. The sources of 2D and/or 3D content may be scrolled, zoomed and/or navigated through for generating the different viewport. Content for the different viewport may be processed. Images of a viewer's positions, angles and/or movements of face, facial expression, eyes and/or physical gestures are captured by the camera and interpreted by face and/or eye tracking. The different viewport may be generated for navigating through 3D content and/or for rotating a 3D object. The 2D and/or 3D video processing device communicates via wire, wireless and/or optical interfaces. | 01-15-2015 |
