<p>A video streaming system includes a streaming server (101) which stores video streams and a transcoding device (102) which receives the video stream desired by a terminal (103), and analyzes the video stream to transcode only a video stream which falls within a range in which transcoding is required, when transmitting the video stream to the terminal (103) upon transcoding it into a video stream which can be transmitted from an arbitrary position designated by the terminal (103). The transcoding device (102) generates a playback start frame by a video transcoder (108) when the video stream reaches a playback start position, and analyzes subsequent frames by using the video transcoder (108). The transcoding device transcodes a video stream only when transcoding is required, while outputting a video stream without any change when transcoding is not required.</p> |
