摘要： PROBLEM TO BE SOLVED: To provide a recording and reproduction method for realizing seamless reproduction with high quality without causing contradiction of overflow and underflow at the connection of the VBV buffer in the case of joining the first MPEG image data to the second MPEG image data and reproducing the resulting image data. SOLUTION: Data of a joining interval A of the first MPEG image data and data of a joining interval B of the second MPEG image data are decoded and then re-encoded. The re-encoding is executed while being controlled so that transition of a VBV buffer occupied value is started from a VBV buffer occupied value at a position (m) and finished up to a VBV buffer occupied value at a position (q). Then the first MPEG image data are reproduced until the position (m) of the first MPEG image data, and then re-encoded MPEG image data at the joining interval A+B are reproduced, and thereafter connection is made to the VBV buffer at its address position (q) of the second MPEG image data and the second MPEG image data after the position (q) are reproduced.

摘要： PROBLEM TO BE SOLVED: To provide a recording and reproducing apparatus that can materialize seamless high-grade reproduction without causing inconsistency of overflow or underflow in connection of a VBV buffer in reproduction linking data from first MPEG image data to second MPEG image data. SOLUTION: This recording and reproducing method encodes again the data of a connection block B of the second MPEG image data after decoding the data. This recoding is controlled for execution so that the transition of a VBV buffer occupation value may be started from the VBV buffer occupation value at a point (i) and be finished until the VBV buffer occupation value at a position (l). Then, this method performs reproduction of the first MPEG image data until the position (i) of the first MPEG image data, next reproduces the recoded MPEG image data in a connection block B, then connects it to the position (l) of the second MPEG image data and reproduces the second MPEG image data on or after the point (l).

摘要： PROBLEM TO BE SOLVED: To provide an information reproducing device capable of identifying a user among a plurality of users and setting a reproduction starting position based on a past stop position for each user.
SOLUTION: A user A first inputs a user name and a password as user setting to a hard disk recorder 10. After the user setting, the user A starts the reproduction of a program #1 from its head position. When the reproduction is suspended, an information management part 11 sets the reproduction suspended time as the resume point of the user A, and stores and manages it as the program information of the program #1 in a program information storage part 113. Next time the user A reproduces this program #1, the information management part 11 confirms the resume point of the user A of the program #1 on the basis of the stored program information of the program information storage part 113, and starts the reproduction of an HDD 12 from a position corresponding to the reproduction suspended time. Operations are similar for other users B and C. Thus, the impossibility of starting the reproduction of information recorded in a hard disk used by the plurality of users from the last stop position for each user is eliminated.

摘要： PROBLEM TO BE SOLVED: To solve the problem that it takes long and costs much conventionally to perform conversion processing with image data and audio data and there is fear that cryptographic information is damaged when the cryptographic information is embedded as digital watermark information in a transformation coefficient calculated by using orthogonal transformation such as DCT. SOLUTION: An add subtract quantity calculator 5 calculates a quantity of add subtract to be added to and subtracted from a luminance signal within a pixel block on the basis of the cryptographic information from a cryptography converter 6 so that an average value of the luminance signal in the pixel block of a filtration signal from a parameter calculator 4 is changed. An embedding signal creator 7 increases and decreases signals inside the pixel block of the filtration signal according to a prescribed rule on the basis of a difference and the add subtract quantity every signal in the corresponding pixel block between a digital signal and the filtration signal, and creates the embedding signal every pixel block. An adder 8 adds the embedding signal every pixel block and the filtration by the pixel and, on the basis of a bit value of the cryptographic information, outputs a cryptographic information embedding signal whose pixel luminance value is corrected.

摘要： PROBLEM TO BE SOLVED: To provide an electronic watermark embedding program and an electronic watermark detecting and falsification discriminating program for detecting the presence / absence of data falsification in the reliability certification of digital image data.
SOLUTION: Statistic information related to an image signal obtained from a first area is embedded to the first area as first electronic watermark information and information equivalent to the first electronic watermark information in a different expression form from that of the first electronic watermark information is embedded to a second area different from the first area as second electronic watermark information. In the case of detecting falsification, two embedded information items are detected and compared, and when the values of the two information items are coincident, it is discriminated that no falsification exists in the image signal in the first area and when the values of the two information items are dissident, it is discriminated that falsification exists in the image signal in the first area.
