| A scalable information signal is protected in a more efficient and/or safe way by adopting the inter-relationship among the plurality of portions of different levels within the information signal in FEC protecting the information signal. In particular, portions of the information signal representing the information content at a higher level should have associated therewith redundancy information which is dependent not only on that part of this portion being disjoint to a respective overlapping lower level portion. Rather, redundancy information should also be dependent on the latter part so as to increase the chances of success of forward error correcting an error within the lower level portion at the reception side. | ||||||

| <P>PROBLEM TO BE SOLVED: To perform efficiently ECC-decode for data recorded in a place in which defect on a recording medium exists. <P>SOLUTION: A parameter is set to an initial value, normal reproduction is performed for data read from the prescribed RUB. When ECC-decode by normal reproduction is not completed normally, retry reproduction is performed. In retry reproduction, a table pointer is referred, a parameter corresponding to a parameter table number of a value stored in the table pointer is set. When ECC-decode by retry reproduction is completed normally, a parameter table number corresponding to a set parameter is stored in the table pointer. Meanwhile, when ECC-decode is not completed normally by retry reproduction, a parameter corresponding to a parameter table number of a value in which the value stored in the table pointer is increased further by only 1, is set. Then, retry reproduction is performed again. <P>COPYRIGHT: (C)2010,JPO&INPIT | ||||||

| Initially the message frame comprising a header with length information, a data portion and a check sequence is expanded with gaps inserted to the data portion and the frame check sequence and the frame length information is updated, the frame is then scrambled and forward error correction data is generated and written into the gaps. An outer check sequence is generated and appended as part of the frame, after which the entire frame is transmitted. Error control decoding of the transmitted frame is achieved between reception and descrambling at a receiving device. The outer check sequence is optionally checked and removed, an error correction algorithm is applied to the frame in response to errors, after which the frame is descrambled, the forward error correction data and the inserted gaps are removed and the frame is restored to its original state and the length information is updated to its original value. | ||||||

| PROBLEM TO BE SOLVED: To realize the efficient calculation of error correction data. SOLUTION: When the error correction data to be inserted to transmission data at certain insertion intervals are generated by calculating the exclusive OR regarding the transmission data, the exclusive OR of the transmission data is continuously and cumulatively calculated independently from the insertion intervals. The error correction data to be inserted this time are generated by calculating the exclusive OR of the calculated value of the exclusive OR at the time when the error correction data are inserted last time, and the calculated value of the exclusive OR at the scheduled time of inserting an error correction packet this time.

| PROBLEM TO BE SOLVED: To protect copyright as far as possible although a high speed dubbing function can be used, by clocking a prescribed time by making it correspond to discriminating information for identifying a program as reproducing information or a reproducing medium on the reproducing side, and thus preventing high speed dubbing of the reproducing information identified by discriminating information of which a clocking time has not elapsed. SOLUTION: Started high-speed-dubbing of music of a certain track, an MD recorder/player 1 detects an ISRC (an identifier peculiar to the track) of Q-channel data, and stores this IRSC in an IRSC management table 29 if the detected ISRC is not stored therein 29, and selects one unused timer from plural timers in a timer part 28 to activate it. When the timer has concluded a predetermined elapsed time, the MD recorder/player deletes the IRSC from the IRSC management table 29, and stops the high speed dubbing if he IRSC is already stored in the IRSC management table 29. | ||||||
