摘要： The content of a media program is recognized by analyzing its audio content to extract therefrom prescribed features, which are compared to a database of features associated with identified content. The identity of the content within the database that has features that most closely match the features of the media program being played is supplied as the identity of the program being played. The features are extracted from a frequency domain version of the media program by a) filtering the coefficients to reduce their number, e.g., using triangular filters; b) grouping a number of consecutive outputs of triangular filters into segments; and c) selecting those segments that meet prescribed criteria, such as those segments that have the largest minimum segment energy with prescribed constraints that prevent the segments from being too close to each other. The triangular filters may be log-spaced and their output may be normalized.

摘要： PROBLEM TO BE SOLVED: To generate a summary of contents with compressibility that a user requests and to distribute the compressed contents to the user who desires to buy when contents are sold from a contents storage means. SOLUTION: Speech information is separated from contents and analyzed to extract a speech phrase in a stressed state. When the total of extracted speech phrases which are connected is within a range of compressibility that the user desires, the speech phrases and video information corresponding to the speech phrases are distributed as summary information as they are, but when the total of the extracted phrases which are connected is not within the range of the compressibility that the user desires, on the other hand, the probability of the stressed state or the probability of a calm state is weighted and speech phrases in stressed states are discriminated again to finally obtain summary information of the compressibility that the user desires, thereby distributing the summary information to the user.

摘要： PROBLEM TO BE SOLVED: To make appropriately detectable a scene change.
SOLUTION: In a step S2, the amplitude of each of sub-band signals decomposed into spectrums in a step S1 is detected. In a step S3, the amplitude of each of sub-band signal is smoothed and sampled corresponding to time for smoothing. In a step S4, on the basis of a value F (n, k) of the smoothed sub- band amplitude and a value F (n-1, k) of the preceding sampled smoothed sub- band amplitude, a spectrum change amount D is calculated. In a step S5, it is decided whether the calculated spectrum change amount D is greater than a prescribed threshold or not and in a step S6, processing based on the decided result is executed.

SOLUTION: This noise-estimating device for estimating noise in a voice signal, has a time domain extracting part 12 for extracting an input signal for a prescribed period, a time and frequency converting part 13 for converting the extracted input signal in a prescribed period into a frequency domain signal, a frequency domain dividing part 14 for performing frequency domain division of the frequency domain signal in each prescribed frequency band, and a noise estimating part 15 for estimating the noise. The noise-estimating part 15 estimates noise, by referring to the past frequency domain signals for a prescribed period in each divided frequency domain.
