摘要： PROBLEM TO BE SOLVED: To provide an information reproducing device, in which a user is discriminated out of a plurality of users, and a reproduction start position based on a past stop position can be set for each user.
SOLUTION: A user inputs initially a user name and a pass word to a hard disk recorder 10 as user setting. After user setting, the user A starts reproduction of a program #1 from the head position, when reproduction is interrupted, an information control part 11 makes a time at which reproduction is interrupted as a resume point of the user A, stores it in a program information storage part 113 as program information of the program #1 and controls it. The next time, when the user A performs reproduction operation of the program #1, the information control part 11 confirms the resume point of the user A of the program #1 based on stored program information of the program information storage part 113, and starts reproduction of a HDD 12from a position corresponding to a time at which reproduction is interrupted. The other users B, C also can perform in the same way.

摘要： PROBLEM TO BE SOLVED: To provide reproduction equipment 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 reproduction equipment encodes again the data of a connection block A of the first MPEG image data and the data of a connection block (B) of the second MPEG image data after decoding them. 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 (m) and be finished until the VBV buffer occupation value at a position (q). Then, this equipment performs reproduction of the first MPEG image data until the position (m) of the first MPEG image data, next reproduces the recoded MPEG image data in a connection block A+B, then connects it to the position (q) of the second MPEG image data and reproduces the second MPEG image data on or after the point (q).

摘要： PROBLEM TO BE SOLVED: To provide a digital signal modulation method that conducts high performance DSV(digital sum value) control without causing a low frequency component even at points of time other than a DSV control point of time because the reduction in the low frequency component is not sufficient by a conventional method that reduces the absolute value of a DSV value at the DSV control point of time.
SOLUTION: When choices are detected in a source code fed to a conversion section 12, a DSV square operation product extracted respectively from DSV square operation integral memories 128, 129 is fed to a square integral value comparison section 130, which compares the DSV square operation integral values of the both and gives the obtained comparison result to a memory control code output section 131. The memory control code output section 131 obtains a code word with a smaller DSV square operation integral value from a code word memory 124 or 125 on the basis of a supplied comparison result as a code word sequence comprising the code word supplied in succession to a synchronous word and outputs the obtained code sequence as a digital modulation signal subjected to (p-q) modulation.
