Abstract
A client device requests a streaming video from a storage device, which encodes the video's frame in communication packets according to an encoding protocol for transmission to the client. The client device decodes the communication packets to obtain frame segments and a frame marking header indicating a boundary of the video frame relative to other video frames in the video. The communication packets may also include other segment headers indicating a relative ordering of corresponding frame segments. The client device determines, based on the frame marking header, whether a sufficient number of communication packets have been received to render a video frame. In response to determining that the sufficient number of communication packets has been received, the client device assembles the video frame from the frame segments corresponding to the video frame and presents at least a portion of the video by rendering the assembled video frame.
