Abstract
In a computing device for streaming media content, information relating to a video bitstream is transmitted to a client device for displaying a user interface. An input signal is received from the client device indicating a desired start time in the video bitstream. Based on the start time, a target key frame is identified within the video, the target key frame comprising a nearest key frame in the video bitstream preceding the desired start time. A target frame header comprising a nearest header frame in the video preceding the target key frame is identified within the video bitstream. If necessary, the target key frame is converted to a first frame type. Only the target frame header, the target key frame, and video bitstream that follows the converted target key frame is sent to the client device, where the original frame referencing encoded in the video bitstream is utilized.
