Cloud Based Mobile Video Editing System

Mobile video editing systems need efficient streaming transmission and interactive operations. Rather than using a specialized protocol and stream format, the video editing system makes use of a generic mechanism based on chunks in the cloud computing environment. Chunks are in fixed-size and contains a mixture of scalar data and references to other chunks. Chunks allow programmers to expose large, but fine-grained, data structures over the network. The video editing system organizes video clips with simple data types including linked lists and search trees, allowing a client to retrieve. The mobile video editing system supports resource adaptive play-back and "live" streaming of real-time video as well as fast, frame-accurate seeking, bandwidth-efficient high-speed play-back, and compilation of editing decisions from a set of clips. All the editing functions are completed in the cloud center and the editing results are showed on the mobile devices. Evaluations indicate that our system uses less bandwidth than HTTP Live Streaming while providing better support for editing primitives.
