摘要： A system and method provide random access to a multimedia object over a network. One embodiment of the invention includes a streaming media server that is connected to a client computer over a network. The streaming media server includes at least one multimedia object that is adapted for transmission (“streaming”) across the network. A pre-roll calculation program determines a pre-roll for each segment of the multimedia object and generates a modified multimedia object which includes a pre-roll for each of its segments, a pre-roll identifying a portion of the multimedia object to be transmitted by the streaming media server and received by the client computer prior to playback of the multimedia object at a selected segment. The pre-roll allows the client computer to present, starting at a selected segment, the multimedia object in its entirety without interruption. The pre-roll calculation program further facilitates the design of the multimedia object to minimize delays associated with random accesses to segments of the multimedia object.

摘要： In various embodiments, a unidirectional broadcast network is utilized to provide digital content to users in a manner that allows users' computing devices to maintain synchrony with personal, relevant information. In at least some embodiments, the broadcast network utilizes a data channel and a signaling channel. The data channel is used for broadcasting data to various users, while the signaling channel—typically used for transmitting device or machine specific data—is used to transmit user-specific information associated with the information or data that the user finds relevant. This user-specific information can then be used by the user's mobile computing device to manage, e.g. record and place into device database for time shifted retrieval, such information or digital objects delivered over the broadcast data channel.

摘要： The disclose describes a system and method for maintaining network access rules for device applications using a state graph of the device application. A rules update agent generates a state graph by recursively exercising internal state transitions and recording network locations of a corresponding resource server associated with the state transition. The internal states of the application are reflected as nodes in the state graph. A rule list is generated from the state graph to identify which states have access to which resource servers. The rules update agent is also configured to dynamically generate a truncated state graph from which a transitory rule list is generated.

摘要： The present invention provides a system and methods for producing multiple encoded representations of a video input sequence. The multiple representations produced each contain identified synchronization frames that allow a server and a client to switch between streamed representations in real time without interruption. Synchronization frames are frames of encoded video that can be independently decoded. A representation can thus be decoded starting at a synchronization frame. Each synchronization frame in one representation has a corresponding synchronization frame at a substantially similar temporal location in any other generated representation of the same video input sequence. The temporal co-location of synchronization frames in all representations facilitates the dynamic switching between representations during the streaming process. The present invention also provides a video encoder application that shares data during the encoding of multiple representations of a video input sequence by reusing data calculated in the encoding of one representation to encode other representations. The application can also generate the multiple encoded representations simultaneously.
