Abstract: A protocol mismatch detection system (1) includes: a protocol database (10); input means (11) for inputting data to be accumulated in the protocol database (10); protocol data accumulation means (12) for accumulating the inputted data in the protocol database (10); announced content reception means (13) for receiving an announced content from outside; a protocol mismatch detection means (14) for referencing the protocol database (10) to detect a portion of the announced content received which does not coincide with the protocol of a user in the protocol mismatch detection system (1); and output means (15) for outputting the detected protocol mismatch and the protocol mismatch portion.

Abstract: To provide a content processing technique which enables to prevent a reading person from easily guessing the fact of hiding and hidden information, and to obtain a content having natural information close to information of its original content before hiding. A content processor includes a search means which searches contents having information similar to a part excluding a part to be hidden in the original content, an arithmetic means which calculates non-similarity which shows the degree of non-similarity of each content obtained by the search means to the part to be hidden of the contend, and a selection means which selects the content which is the least similar to the part to be hidden out of the contents searched by the search means.

Abstract: A CM feature data extracting unit 22 extracts a feature data 24 of a section corresponding to a CM from broadcasting signals received by a receiving facility 21. A checking portion 23 checks the feature data 24 against a CM feature data registered with a DB 3. The checking portion 23 registers, with the DB 3, the CM feature data 24 determined not being included in the DB 3 as a new CM. The feature data calculating portion 42 extracts a feature data 44 from broadcast waves received by a receiving facility 41. A checking unit 43 checks the feature data 44 against a CM feature datatored with the DB 3. When they agree, a checking portion 4 sends out a checking result 45 to a recording portion 5. The recording portion 5 creates a report 51 from the checking result 45 and submits the report 51 to a client 1. A broadcast checker 6 receives a broadcast checking charge 11 in compensation for the report 51.

Abstract: In an adaptive transform coding system and/or and adaptive transform decoding system, coding efficiency in the case where a small number of quantized values having large absolute value are present, is improved. The adaptive transform coding system codes the small number of quantized values having large absolute values and other quantized values are coded separately. More particularly, the adaptive transform coding system includes a selector (6) discriminating the small number of quantized value having large absolute value from other quantized value, a pulse coding means for coding the small number of quantized values having large absolute values (8) and the pulse decoding means (16) for decoding the same, a coding means (7) for coding the quantized value other than those having large absolute values and a decoding means (15) decoding the same, and a synthesis means (18) for synthesizing the small number of quantized values having large absolute value and other quantized values.

Abstract: Digital samples of an underlying analog audio-frequency signal are converted to transform coefficients and a first bit assignment value indicating the number of quantization levels or bits is adaptively assigned to each coefficient according to the power distribution of the transform coefficients. The transform coefficients are weighted according to a prescribed pattern such as human's auditory sensitivity, and a second bit assignment value is further adaptively assigned to each transform coefficient according to the power distribution of the weighted transform coefficients. One of the first and second bit assignment values is selected according to the power distribution of the transform coefficients and used to quantize the transform coefficients. The quantized transform coefficients are multiplexed with supplemental information derived from the transform coefficients for transmission to a receiving site.

Abstract: Subblocks of input digital samples are stored into a buffer at frame intervals and segmented into blocks having an integral multiple of the length of the subblock. Each block is encoded into transform coefficients and stored into a memory. Each coefficient is squared and those of the squared transform coefficients which correspond to high-frequency components of the input digital samples are summed and a minimum value is detected therefrom as corresponding to an optimum block length. Those transform coefficients which correspond to the optimum block length are selected from the memory and multiplexed with a signal representative of the optimum block length. In a modification, interblock differences are detected between successive transform coefficients of equal block length and squared. Those of the squared interblock differences which correspond to equal block length are summed, producing a set of squared sums for each block length.

Abstract: In an apparatus for carrying out a linear transform calculation on a product signal produced by multiplying a predetermined transform window function and an apparatus input signal, an FFT part (23) carries out fast Fourier transform on a processed signal produced by processing the product signal in a first processing part (21). As a result, the FFT part produces an internal signal which is representative of a result of the fast Fourier transform. A second processing part (22) processes the internal signal into a transformed signal which represents a result of the linear transform calculation. The apparatus is applicable to either of forward and inverse transform units (11, 12).
