no. 1 Embodiment approach

[0057] FIG. 1 is a block diagram showing the configuration of a digest generation device according to the first embodiment of the present invention. In FIG. 1 , the summary generating device 10 is composed of a receiving unit 11, a feature amount calculating unit 12, a silent interval detecting unit 13, a candidate interval detecting unit 14, a CM interval judging unit 15, an abstract list making unit 16, and a large-capacity recording medium 17. , and the playback control unit 18 constitutes.

[0058] The receiver 11 receives broadcast waves and demodulates them into image signals and audio signals (hereinafter referred to as AV signals). In addition, the receiving unit 11 outputs the demodulated AV signal to the feature amount calculating unit 12 , the large-capacity recording medium 17 , and the reproduction control unit 18 .

[0059] The feature quantity calculation unit 12 analyzes the above-mentioned AV signal, calculates the feature quantity, and outputs it to the sile...

no. 2 Embodiment approach

[0100] Next, a second embodiment of the present invention will be described with reference to FIGS. 10 to 13 . In the above-described first embodiment, candidate sections of digest scenes are detected at any time. In contrast, in the second embodiment, the candidate section is not detected, but the feature quantity required for digest scene detection is accumulated for a predetermined time, and the digest scene is detected based on the feature quantity other than the CM section at a predetermined timing. . FIG. 10 is a block diagram showing the configuration of a digest generation device 30 according to the second embodiment of the present invention. In FIG. 10 , the feature value calculation unit 12 associates the calculated feature value with time information, and stores it in the temporary storage unit 31 as a temporarily accumulated feature value 36 . The temporary storage unit 31 has a capacity to hold frame feature data and time information for a predetermined period o...

Abstract

A feature value calculation unit (12) calculates feature values ​​from the received AV signal. A silent interval detection unit (13) detects an interval in which the sound power level is equal to or less than a predetermined value as a silent interval. A candidate section detection unit (14) detects a section whose audio power level is equal to or less than a predetermined value as a digest scene candidate section. A CM section judging unit (15) judges a CM section based on a time interval between silent sections. A digest list creation unit (16) deletes a section corresponding to the judged CM section from the digest candidate section, thereby generating digest scene information in the program section excluding the CM section.

Description

technical field [0001] The present invention relates to generation of digest scenes, and more specifically, to generation of digest scenes in which feature quantities of images and sounds are calculated from television broadcasts, etc., and specific important scenes are identified using these feature quantities. Background technique [0002] Conventionally, there has been a digest generating device that calculates feature quantities of video and audio from television broadcasts, etc., and specifies important scenes using these feature quantities. In this kind of device, the following methods are generally adopted for generating the summary. First, from the AV signal already recorded on the recording medium, the video / audio feature value of one program is calculated, the CM (commercial) interval is detected based on these feature amounts, and the timing of the digest playback playlist etc. is calculated from outside the CM interval information. [0003] Next, the configurat...
