摘要： A picture target amount-of-code calculating unit calculates a target amount of codes for each picture type that corresponds to an encoding rate that has been determined by an audio/video encoding rate determining unit. An amount-of-code controlling unit controls the quantizing scale of a quantizing unit so as to make the target amount of codes for each picture type match with a total amount of codes of a unit as a whole. A unit address calculating unit calculates the addresses used when a search is made, as navigation data, on the basis of the target amount of codes for each picture type and the encoding rate. A unifying unit makes a construction of the unit while, on the other hand, a navigation data producing unit depicts navigation data at a foremost position of the unit.

摘要： Among a first and second video data each being variable length coded data such that an occupancy of a decoder buffer is neither overflown nor underflown, having an end code at a rear end thereof and being comprised of a plurality of compressed portion data, a value related to a buffer occupancy at a decoding timing of the last picture of the first video data is compared by an invalid data amount calculator 13 with the buffer occupancy at the decoding timing of the first picture of the second video data. According to a data amount corresponding to a difference between the occupancies when the result of comparison is a predetermined one, the invalid data of this data amount is added by an invalid data adder 14 to the last picture of the first video data and the second video data is connected by a video data connector 15 to the first video data.

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： An inferential method is disclosed, where fact information and a time tag assigned thereto are matched and stored. A rule group is stored. A pattern match of the fact information and the rule group is executed. A combination of the fact information and the rule group is selected. When a plurality of combinations have been selected, one of them is further selected. The selected rule is executed and new fact information in the working memory is created. When new fact information is created to the working memory by executing the rule, if the time tag assigned to the fact information exceeds the given value, the time tag which has been assigned to the fact information in the working memory is reassigned.

摘要： When a code word sequence is generated by converting input data words of p bits into code words of q bits and concatenating adjacent ones of the code words with a merge bit sequence of r bits in order to obtain the best DSV value, according to one aspect, the adjacent code words are concatenated with the merge bit sequence of r bits which is selected, free from the restriction of the minimum run-length of (d+1)T and the maximum run-length of (k+1)T based on the run-length limiting rule RLL(d, k) but permitting the minimum run-length of (d+1)T and the maximum run-length of (k+2)T. According to another aspect, a merge bit sequence to be inserted after a current code word is selected by prefetching the current code word, a next code word, and a further next code word, temporarily concatenating these code words with merge bit sequences of r bits respectively to prepare code word sequence candidates free from the predetermined run-length limiting rule, calculating the DSV values of the code word sequence candidates, selecting one of the code word sequence candidates having a DSV value whose absolute value is closest to zero, and selecting the merge bit sequence between the current code word and the next code word of the selected merge bit sequence candidate. According to a further aspect, the input data words are encoded by a p-q modulation scheme after introducing for a predetermined period, as an input data word, specific data comprising alternating current signals or direct current signals which would cause a modulation device that prefetches only the next code word to output a code word sequence which includes particular frequency components.
