Patent ID: 8665963

Claim:
A communication terminal comprising: a communicator configured to transmit and receive data to and from a server storing video contents; an accumulator configured to accumulate a plurality of partial streams extracted from different time positions within the video contents received through the communicator as asynchronous streams; a decoder configured to decode at least one of the asynchronous streams and synchronous streams that are not extracted as the asynchronous streams from the video contents, the synchronous streams being streaming-distributed from the server; and a controller configured to acquire streams having time position information after a reproduction time position of the at least one of the asynchronous streams and the synchronous streams decoded by the decoder while the at least one of the asynchronous streams and the synchronous streams are reproduced on a display, and control the display to display the acquired streams after the reproduction, wherein the plurality of asynchronous streams have a predetermined time length, respectively, wherein the controller is configured to request the server to transmit the synchronous stream when the reproduction time position of the asynchronous streams exceeds a predetermined time position; and wherein the communication terminal further comprises: a first acquisition unit, configured to read the asynchronous streams from the accumulator, and convert a timestamp assigned to the read asynchronous streams into a uniform timestamp within the communication terminal; a first buffer, configured to temporarily store the synchronous streams distributed from the server; a second acquisition unit, configured to read the synchronous streams from the first buffer, and convert a timestamp assigned to the read synchronous streams into the uniform timestamp; and a second buffer, configured to temporarily store the asynchronous streams acquired by the first acquisition unit and the synchronous streams acquired by the second acquisition unit, and output the stored asynchronous streams and the stored synchronous streams to the decoder.
