<p><P>PROBLEM TO BE SOLVED: To provide a device and a program for decoding compression video data capable of reducing throughput in the case of decoding the compression video data by fast forward. <P>SOLUTION: The device for decoding the video data is provided with a user interface in which the compression video data in which video data corresponding to real time is encoded is inputted and which accepts a shortening instruction for outputting the video data by shortening the real time, a structural analysis part 101 which analyzes the compression video data and a picture deletion part 102 which determines an output picture based on the accepted shortening instruction and a predetermined frame rate and deletes compression video data corresponding to pictures except the determined output picture or compression video data corresponding to pictures except the output picture and a reference picture when the output picture has the reference picture. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
