VIDEO/SOUND DISTRIBUTING DEVICE AND VIDEO/SOUND FILE ANALYZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a video/sound distributing device which shortens a response time from the reception of a video/sound transmission request till the transmission of a video/sound stream and suppresses the usage amount of main storage in the video/sound distributing device. SOLUTION: A video/sound file analyzing part 6 analyzes a video/sound file which is preserved in a video/sound file preserving part 4 and preserves the result in a video/sound file analysis result preserving part 7. When main storage is not sufficient for preservation, an existing analysis result is erased. When information concerning the video/sound file is requested from a video/ sound data obtaining part 5, the video/sound the analyzing part 6 returns requested information to the part 5 when the information exists in the video voice file analysis result preserving part 7. Thus the response time from the reception of the video/sound transmission request till the transmission of video/ sound is shortened and the usage amount of the main storage is suppressed in the video/sound distributing device.
