摘要： Systems and methods are presented herein that facilitate temporally synchronizing, in real time, a separately sourced high quality audio segment of a live event with a video segment that is generated by a recording device associated with a member of the audience. An A-V Synchronization Application may synchronize a video segment of a live event that is generated from a personal electronic device of an audience member with a high quality audio segment that is separately sourced and generated by professional sound recording equipment at the live event. The result of the temporal synchronization is a high fidelity digital audio visual recording of the live event. In various, the audience member may stream, in real-time, the high fidelity digital audio visual recording to an additional electronic device at a different geo-location. In some examples, narrative audio segments may be also included as part of the high fidelity digital audio visual recording.

摘要： Systems and methods of adaptive streaming are discussed. Transcoded copies of a source stream may be aligned with one another such that the independently specified portions of each transcoded stream occur at the same locations within the content. These transcoded copies may be produced by one or more transcoders, whose outputs are synchronized by a delay adjuster. A fragmenter may use the synchronized and aligned streams to efficiently produce fragments suitable for use in adaptive streaming.
