20150113102 | FILE DELIVERY OVER A BROADCAST NETWORK USING FILE SYSTEM ABSTRACTION, BROADCAST SCHEDULE MESSAGES AND SELECTIVE RECEPTION - Methods provide mechanisms for efficiently delivering files over a broadcast system to mobile devices. Files for broadcast may be logically identified as belonging to a directory in a file system. A Broadcast Schedule Message may inform receiver devices of files that will be broadcast at a specified time, as well as describe the files. File may be transmitted in file delivery pipes, which may be of different bandwidth and data rates. Receiver devices configured according to the embodiments may make use of the broadcast schedule message to select files to be received based on the service or application with which the file is associated, and whether the file is new or an update to a previously received file. Receiver devices activate receiver circuitry to capture the files within their advertised broadcast window, and pass the files to be broadcast to applications or services requesting the files. | 04-23-2015 |
20150156498 | METHODS AND SYSTEMS FOR RESIZING MULTIMEDIA CONTENT BASED ON QUALITY AND RATE INFORMATION - In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules. | 06-04-2015 |
