摘要： A DSV control bit determining/inserting unit inserts DSV control bits for execution of DSV control into an input data string and outputs the data string including the DSV control bits to a modulation unit. This modulation unit converts the data string with a basic data length of 2 bits into variable length code with a basic code length of 3 bits in accordance with a conversion table and outputs the code resulting from the conversion to a NRZI encoding unit. The conversion table used by the modulation unit includes substitution codes for limiting the number of consecutive appearances of a minimum run to a predetermined value and substitution codes for keeping a run length limit. In addition, the conversion table enforces a conversion rule, according to which the remaineder of division of the “1” count of an element in a data string by 2 having a value of 0 or 1 shall always be equal to the remainder of division of the “1” count of an element in the code resulting from conversion of the data string by 2.
摘要翻译： DSV控制位确定/插入单元将用于执行DSV控制的DSV控制位插入到输入数据串中，并将包括DSV控制位的数据串输出到调制单元。该调制单元根据转换表将具有2位的基本数据长度的数据串转换为具有3位的基本码长度的可变长度码，并将从转换得到的代码输出到NRZI编码单元。由调制单元使用的转换表包括用于将最小运行的连续出现次数限制为预定值的替换代码和用于保持游程长度限制的替代代码。另外，转换表执行转换规则，根据该转换规则，数据字符串中的元素“1”计数的剩余值除以2，值为0或1，总是等于由数据字符串转换得到的代码中的元素的“1”计数为2。

摘要： A data-demodulating apparatus for demodulating a variable-length code (d, k; m, n; r) having a basic code length of n bits to data having a basic data length of m bits. A train of codes is received, and a sync signal having a pattern that breaks a maximum run is detected. The pattern is repeated twice continuously and the minimum run is repeated no more than six times. The first bit of the sync signal is “1” when the train of modulated codes that immediately precedes the sync signal is included in a termination table used to terminate, at a desired position, a code when less than a predetermined number of variable length codes are available.

摘要： This invention relates to an information processing apparatus and an information processing method for simply providing the results of searches as expected by users searching for broadcast content. A search space processing section 103 acquires a search keyword based on search information coming from a user terminal, and searches a search keyword dictionary database for search-related keyword data related to the search keyword. On the basis of the search keyword and search-related keyword data, the search space processing section 103 generates a search keyword space and submits the generated space to a correction process. A search processing section 104 compares the corrected search keyword space, EPG data, and an EPG keyword space for a match. A search display processing section 105 prepares a list of display-ready information from the result of the matching and sends the list to the user terminal. This invention can be applied advantageously to systems that provide broadcast content information over the Internet.

A DSV control bit determining/inserting unit 11 inserts DSV control bits for execution of DSV control into an input data string and outputs the data string including the DSV control bits to a modulation unit 12. The modulation unit 12 converts the data string with a basic data length of 2 bits into variable length code with a basic code length of 3 bits in accordance with a conversion table and outputs the code resulting from the conversion to a NRZI encoding unit 13. The conversion table used by the modulation unit 12 includes substitution codes for limiting the number of consecutive appearances of a minimum run to a predetermined value and substitution codes for keeping a run length limit. In addition, the conversion table enforces a conversion rule, according to which the remainder of division of the “1” count of an element in a data string by 2 having a value of 0 or 1 shall always be equal to the remainder of division of the “1” count of an element in the code resulting from conversion of the data string by 2.

摘要： A device is disclosed for encoding a stream of databits of a binary source signal (S) into a stream of databits of a binary channel signal (C), wherein the bitstream of the source signal is divided into n-bit source words (x1, x2), which device comprises converting means (CM) adapted to convert said source words into corresponding m-bit channel words (y1, y2, y3). The converting means (CM) are further adapted to convert n-bit source words into corresponding m-bit channel words, such that the conversion for each n-bit source word is parity preserving (table I) (FIG. 1). The relations hold that m>n≧1, p≧1, and that p can vary. Preferably, m=n+1. The device is adapted to convert the 8-bit bit sequence ‘00010001’ in the source signal into the 12-bit bitsequence ‘100010010010’ and to convert the 8-bit bitsequence ‘10010001’ into the 12-bit bitsequence ‘000010010010’, in order to limit the repeated minimum transition runlength in the channel signal. Also other 8-bit sequences require a specific encoding into 12-bit bitsequences in order to limit the k-constraint of the channel signal to 7. Further, a decoding device is disclosed for decoding the channel signal obtained by means of the encoding device.
