摘要： PROBLEM TO BE SOLVED: To provide a technology whereby a user can grasp contents of moving pictures until a prescribed time or to the utmost extent for a desired time. SOLUTION: This moving picture reproducing apparatus includes: a moving picture data input means; a ranking data input/generating means for receiving or generating ranking data ranked in response to the importance by each scene of the moving picture data; a reproduction scene determination parameter input means for receiving a parameter for determining a scene to be reproduced depending on importance; and a reproduction scene determining means for determining a reproduction scene on the basis of the ranking data and the reproduction scene determining parameter. The reproduction scene determination parameter input means receives a view time of moving picture data desired by the user and the maximum time width of each reproduction scene, and the reproduction scene determining means cuts the scenes so that the reproduction time of the reproduction scenes falls in the maximum time width and determines the reproduction scenes so that the total sum of the reproduction times of the reproduction scenes falls in the view time.

摘要： PROBLEM TO BE SOLVED: To provide the multiplexed audio data decoding apparatus which is capable of easily integrating audio decoders and which has high flexibility, even when the number of formats to be processed is increased or when the specifications are changed.
SOLUTION: In an external ROM 60, a plurality of decoding processing codes, corresponding to respective plural compression encoding systems, are stored. When a user changes the specifications of data series and compression encoding system is changed, a control means 50 transfers the decoding processing code, corresponding to the compression encoding system thereof, after changing, from the external ROM 60 to an internal RAM 25. A DSP 22 starts decoding processing by using the decoding processing code transferred to the internal RAM 25.

摘要： PROBLEM TO BE SOLVED: To provide an electronic watermark insertion system for preventing an image with an electronic watermark inserted thereinto from being illegally tampered. SOLUTION: When electronic watermark information is inserted into an inputted image, this electronic watermark insertion system simultaneously inserts the electronic watermark detection accuracy of the preceding frame of the inputted image. The detection accuracy inserted image is sent to an image encoding device, encoded into a target image format, and stored in an external storage device. In addition, the image encoding device itself decodes the encoded image and sends the decoded image to an electronic watermark detecting device to calculate electronic watermark detection accuracy. The data of the electronic watermark detection accuracy is inserted as electronic watermark for the next frame. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To intermittently output PCM(pulse code modulation) data even at a bit rate where the decode processing of only one channel is conventionally impossible in the reproduction of an encoded audio signal by a quick traverse operation, without enhancing the performance of an audio decoder. SOLUTION: A frame extracting circuit 40 supplies one audio frame to a post-stage channel extracting circuit 80 from the frequency data of all the frames that a stream analysis circuit 70 decoded. Then, the circuit 40 suspends the supply of several next frames. A frequency-time-axis conversion circuit 100 secures the time for decode processing by performing decode while the supply of audio frames are suspended, and then intermittently outputs voice data.
