摘要： A writable storage medium has a first storage area divided into a plurality of sectors having the same data capacity and a second storage area. The first storage area stores at least encoded moving picture data and encoded audio data. The second storage area stores at least first information indicating whether the audio data is silence data, second information indicating an encoding method by which the audio data has been encoded at a constant bit rate and third information indicating the number of audio channels related to the audio data. The first and second storage areas may further store encoded bitmap video data and data identification information indicating whether the bitmap video data is invisible data, respectively. The first information is detected to determine whether the first audio data is silence data. If the first audio data is judged as the silence data, second audio data to be after-recorded is encoded by the encoding method the same as the method for the first audio data at the bit rate the same as that for the first audio data in response to the second and third information. The encoded second audio data is written over the first audio data. The data identification information is detected to determine whether the first bitmap video data is invisible data. Second bitmap video data to be after-recorded is encoded if the first bitmap video data is judged as the invisible data. The encoded second bitmap video data is written over the first bitmap video data.

摘要： In case that a skipping section is provided by editing in a recording region other than a recording region for block data in an information recording medium recorded with at least more than one collation table of time recording location, which is composed of more than one collation data by each fixed time interval and time compensating data, a collation table of time recording location is read out from the information recording medium and divided in response to a designated skipping period. A collation data, which assigns block data of designated skipping period, are deleted. A second time compensating data is calculated in response to the skipping period. Combining the second time compensating data with collation data succeeding the deleted collation data composes a new collation table of time recording location. The new collation table of time recording location is written back to the information recording medium in conjunction with a collation table of time recording location temporally preceding the deleted data.

摘要： Bits of a first bit sequence are rearranged in a first matrix according to a predetermined arrangement rule. The first bit sequence represents information being a base of a key. Blocks are formed in the first matrix. Each of the blocks has bits, the number of which is smaller than the number of bits composing the first matrix. Logical operation is executed among bits in each of the blocks, and a bit being a result of the logical operation is generated. The logical-operation-result bits are combined into a second bit sequence. The number of bits composing the second bit sequence is smaller than the number of bits composing the first bit sequence. There is a second matrix composed of predetermined third bit sequences. The second matrix is accessed and one is read out from among the third bit sequences in response to the second bit sequence. The read-out third bit sequence is outputted as information representative of the key. The number of bits composing each of the third bit sequences is smaller than the number of bits composing the second bit sequence.

摘要： Executes a re-encoding after decoding data of a connection section A of a first MPEG picture data. This re-encoding is executed based on a control such that a transition of a VBV buffer occupation value starts from a VBV buffer occupation value at a position a and ends with a VBV buffer occupation value at a position d. Up to the position a of the first MPEG picture data, the first MPEG picture data is reproduced. Next, re-encoded MPEG picture data of the connection section A is reproduced. Thereafter, the data is connected to the position d of a second MPEG picture data, and the second MPEG picture data of the position d and after is reproduced.

摘要： An audio signal is compressively encoded into encoding-resultant audio data. A video signal is compressively encoded into encoding-resultant video data. An audio time stamp for audio-vide synchronous reproduction is added to every unit of the encoding-resultant audio data. A video time stamp for audio-video synchronous reproduction is added to every unit of the encoding-resultant video data. The time-stamp-added audio data and the time-stamp-added video data are multiplexed into main data. To a plurality of first after-recording-purpose data for at least one of (1) the encoding-resultant audio data and (2) the encoding-resultant video data which form the main data, time stamps for reproduction synchronous with a portion of the main data and identification information for identifying the plurality of first after-recording-purpose data are added to convert the first after-recording-purpose data into second after-recording-purpose data. The second after-recording-purpose data are made into bit streams without being multiplexed with the main data.
