摘要： A video signal is divided into blocks, and an orthogonal transform is performed on each block to obtain transformed coefficients. Of the transformed coefficients thus obtained, dominant transformed coefficients are selected from a low-frequency area and a high-frequency area, and based on the dominant transformed coefficients, an evaluation value is calculated, using which value a specific pattern in the video signal is detected. Based on the specific pattern thus detected, an optimum quantization step size is decided, and the transformed coefficients are adaptively quantized, thus preventing image quality degradation.

摘要： A codeword contains information symbols representing elements of a Galois field, a parity check symbol generated using a certain element of the Galois field, and additional check symbols generated using a polynomial of which this certain element is not a root. The reliability of corrected codewords is assessed by counting the number of symbols found to be in error, or by counting the number of symbols having at least a certain number of bits in error. When a row-column array is decoded, rows of intermediate reliability are not corrected but their error patterns are stored in a memory, and columns of intermediate reliability are corrected if their error patterns match the error information stored in the memory.
摘要翻译：代码字包含表示伽罗瓦域的元素的信息符号，使用伽罗瓦域的某个元素产生的奇偶校验符号，以及使用该特定元素不是根的多项式生成的附加校验符号。校正码字的可靠性通过对发现错误的符号的数量进行计数，或通过计数具有至少一定数量的位错误的符号的数量来评估。当行列阵列被解码时，中间可靠性行不被校正，但它们的错误模式存储在存储器中，并且如果它们的错误模式匹配存储在存储器中的错误信息，则中间可靠性列被校正。

摘要： An error correcting and controlling system forms syndromes S.sub.1 and S.sub.2 for each of a set of reproduced, sampled signal words and error correcting words P or Q and also forms a syndrome S.sub.i =S.sub.1 .sym.T.sup.i-7 S.sub.2 by using the result of a CRC check of the set of sampled signal words. An error position i is determined by three zero counters which respectively indicate S.sub.1 .noteq.0, S.sub.2 .noteq.0 and S.sub.i .noteq.0. Alternatively, the system may further include three counters for respectively counting errors developed in the set of sampled signal words, and the error correcting words P and Q, the errors being detected by a CRC check circuit. When any one of the counters counts an error and the remaining counters count no error with S.sub.1 .noteq.0, S.sub.2 .noteq.0 and S.sub.i .noteq.0, a control signal is generated to perform a concealing operation, such as a means value interpolation, etc.

摘要： A rectangular array of 6.times.150 bits is divided into 50 rectangular arrays of 8.times.3 bits with 2 check bits added, resulting in 50 codes C.sub.2. This encoding is executed 50 times to form a rectangular array of 8.times.150 bits and each of its rows is encoded into a code C.sub.1 of 166 bits with 16 check bits added. This encoding is executed eight times to form a codeword of a generalized product code, which includes 8.times.166 bits and each row following 12 synchronizing bits. Errors are detected in the codes C.sub.1 decoded from the codeword to produce erasure information which is utilized to correct the code C.sub.2. Then, the original array is reproduced.

摘要： Phase signals are sensed from the frame synchronizing signals resulting from a PCM magnetic multitrack record tape and applied to a selector connected to a phase locked oscillator. The oscillator is connected to a gate signal generator. The selector responds to each gate signal from the gate generator to pass only one of the phase signals through the same. The oscillator has its phase synchronized with that of the phase signal passed through the selector and provides the phase signals serving to control the speed of the record tape.
