Abstract:
1. A method comprising: transmitting via a wireless interface from a motion video server to a wireless apparatus, a first data stream comprising a motion video having a plurality of intra-frames, each intra-frame being distant from another intra-frame by at least one inter-frame, the motion video having initial presentation characteristics, wherein the motion video is synchronized to audio data; receiving at the motion video server via the wireless interface a first display control command at the wireless apparatus comprising an indication of intended presentation characteristics of the motion video; creating at the motion video server, based upon reception of the first control command, a second data stream comprising motion video having the intended presentation characteristics, wherein the second data stream is created by filtering inter-frames between each intra-frame of the first data stream, causing the number of inter-frames between each intra-frame to be an altered value from a group of available values, according to a presentation speed selected from a plurality of presentation speeds specified within the first control command; and storing time stamp information for maintaining synchronization of the motion video and audio data comprising the location and timing of each audio and video frame relative to the beginning of the motion video.
