Abstract
A method and apparatus for controlling reproduction of video contents, wherein a user can readily move a play position to a desired scene within a brief period of time to reproduce video contents from the moved play position. The user can pause or replay a desired scene without requesting separate skipping. In particular, in the case where the user requests a pause mode or a normal play mode during a quick browsing mode, rather than during the normal play mode, the present system exhibits many differences from existing systems and excellent performance over them.
Claims20
A method for controlling reproduction of video contents, comprising the steps of:
- a) receiving a user request for pause or replay at a present position while performing a normal speed play or a high speed browsing of the video contents;
- and
- b) selecting an actual pause or replay position on the basis of a play direction and play speed of media, an average user response time, a current play position at a time point that said user request is received, and structural/semantic index information of said video contents in response to said user request.
An apparatus for controlling reproduction of video contents, comprising:
- display means for outputting a video stream;
- user interface means for receiving a user's input;
- media storage means for storing video data;
- index storage means for storing structural/semantic index information of the video contents;
- basic setting and user information storage means for storing media play control information and user information;
- and
- media play control means for receiving said user's request to perform a pause mode or replay mode at a desired position while displaying said video data stored in said media storage means through said display means in a normal play mode or an accelerated play mode, selecting an actual replay or pause position on the basis of a media play direction, a media play speed, a user response time and structural/semantic information change positions, and pausing said video contents at the selected position or replaying them from the selected position at a normal speed.
An intelligent video browsing method using structural/semantic information of video contents, comprising steps of receiving a user request for pause or replay at a present position while performing a normal speed play or high speed browsing of the video contents, and selecting an actual pause or replay position in response to the user request, wherein the method further comprising the steps of:
- a) obtaining a primary candidate position on the basis of an average user response time based on a media play direction and a media play speed;
- b) selecting structural/semantic index information change positions existing within a certain browsing range from said primary candidate position as secondary candidate positions;
- and
- c) extracting a structural/semantic index information change position which is closest to said user request among said secondary candidate positions and setting the extracted structural/semantic index information change position as said actual pause position or normal replay position.
