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： A system and a method determine network conditions. The system includes a server computer and a client computer. The server computer is configured to transmit data packets comprising a data object from the server computer to the client computer. The client computer includes a transmission latency detector and a transmission bandwidth detector. The transmission latency detector uses transmission time and receipt time values to determine the changes in time it takes selected portions of the data object to be transmitted from the server computer to the client computer. The transmission bandwidth detector uses identified back-to-back data packets to determine the transmission bandwidth between the server computer and the client computer.

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.
