摘要： An encoder for encoding a stream of data bits of a binary source signal into a stream of data bits of a binary channel signal, the bitstream of the source signal being divided into smaller n-bit source words (x1, x2) which are converted by a logic circuit converter in the encoder into corresponding m-bit channel words, (y1, y2, y3). The conversion of each n-bit source word is parity preserving (see Table I and FIG. 1). The relations hold that m>n≧1, p≧1, and p can vary. Preferably, m=n+1. In order to comply with (d, k) runlength requirements, certain blocks of 2-bit source words are encoded into particular blocks of 3-bit channel words. A decoder is also disclosed for decoding a channel signal produced by the encoder.
摘要翻译：一种编码器，用于将二进制源信号的数据比特流编码为二进制信道信号的数据比特流，源信号的比特流被分成较小的n比特源字（x1，x2），其被转换为将编码器中的逻辑电路转换器转换成相应的m位通道字，（y1，y2，y3）。每个n位源字的转换是奇偶校验（见表1和图1）。关系认为m> n> = 1，p> = 1，p可以变化。优选地，m = n + 1。为了符合（d，k）游程长度要求，2位源字的某些块被编码成3位通道字的特定块。还公开了一种用于对由编码器产生的信道信号进行解码的解码器。

摘要： An information processing apparatus and an information processing method for providing the results of searches of broadcast content. A search space processing section 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 generates a search keyword space and submits the generated space to a correction process. A search processing section compares the corrected search keyword space, EPG data, and an EPG keyword space for a match. A search display processing section prepares a list of display-ready information from the result of the matching and sends the list to the user terminal.

摘要： Data having a basic data length of m bits is modulated to a variable-length code having a basic code length of n bits. A sync signal is added to the data after a minimum bit-run in the data. The sync signal exhibits two or more patterns, each pattern breaking a maximum bit-run and having six channel bits for identifying each sync signal. The two or more patterns are distinguished from one another, with a detection distance of at least two therebetween.
摘要翻译：具有m比特的基本数据长度的数据被调制为具有n比特的基本码长度的可变长度码。在数据中的最小位运行之后，将同步信号添加到数据。同步信号表现出两种或多种模式，每种模式破坏最大位运行并具有六个通道位用于识别每个同步信号。两个或更多个图案彼此区分，其间的检测距离至少为两个。
