    Abstract: PROBLEM TO BE SOLVED: To carry out the flexible and efficient detection of hierarchical characteristics. SOLUTION: A low-level characteristic detection system 31 is a processing system for detecting the characteristics directly obtained by analyzing a video signal and an audio signal of a content.

    Abstract: PROBLEM TO BE SOLVED: To easily generate a database of content character information made to correspond to video contents. SOLUTION: Some image data are selected out of imaging data as representative image data DPr representative of the imaging data, a representative image 51 based upon the representative image data DPr is displayed on a display device, and a user is made to input image text information TX corresponding to the representative image 51. Further, representative feature information DSr extracted from the representative image data PDr according to an extracting method using luminance and the image text information TX are registered while being made to correspond to each other, thereby generating an image-text database 42 for acquiring content character information TXc corresponding to an image that recorded-imaging data have by using input video feature data TS extracted from an arbitrary video content like the recorded-imaging data in the same extracting method with the representative feature information DSr. COPYRIGHT: (C)2008,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To switch an oscillation frequency range of VCO of PLL for audio clock reproduction on the receiving side according to the change of an audio sampling frequency even without transmitting information indicating the audio sampling frequency as information for locking the PLL for audio clock reproduction on the receiving side. SOLUTION: When a frequency of a pixel clock is set as fp, the audio sampling frequency is set as fs and a frequency of an audio clock to be reproduced is set as fa, fa=384fs=(N/M)fp, in the case of fs=48 kHz, M=27000, N=18432 and in the case of fs=44.1 kHz, M=30000 and N=18816. A VCO control part 50 detects the change of the audio sampling frequency fs from a control voltage Vctl of the output of a loop filter 44 or a frequency fo of an output clock of an oscillation part 30 and selects either of VCOs 31, 32.

    Abstract: PROBLEM TO BE SOLVED: To solve the problem that it is difficult and troublesome to look for a program out of many programs or information about the many programs. SOLUTION: Received EPG information is stored in a database 12. The EPG information is read by a vocabulary segmentation part 31, which segments the read EPG information by the unit of the vocabulary. The segmented vocabulary is supplied to a registration part 41. When the supplied vocabulary is a part of speech or a word set in advance, the registration part 41 registers it in a related information file. A prescribed vocabulary and a program (EPG information) including the vocabulary are correlated and stored in the related information file. The vocabulary stored in the related information file is emphasized and displayed when EPG is provided to a user. The emphasized and displayed vocabulary has a link, and when the vocabulary is selected, information of a link destination is provided to the user. This method can be applied to a set top box dealing with the EPG information. COPYRIGHT: (C)2004,JPO
