Abstract
Within a television broadcast recording/reproducing apparatus, for preventing a commercial message (CM) from being cut when viewing an abridgement (digest), and for presenting the CM to a viewer without losing an advantage of viewing the abridgement, a ranking value of a CM portion is changed, with using a means for evaluating video and audio by one (1) frame thereof, thereby to give a ranking value thereto, and a means for detecting a CM portion.
Claims21
A video recording/reproducing apparatus, comprising:
- a contents input means;
- an evaluating means for evaluating a plural number of frames included within the contents, which are inputted by said contents input means, upon basis of a parameter included in said contents;
- a ranking data producing means for producing a ranking value of each of said frames, upon basis of a result of evaluation, which is obtained within said evaluating means;
- a CM detecting portion for extracting a commercial message from said contents;
- a CM-use ranking data producing means for producing a ranking value of the commercial message, which is detected within said CM detecting portion;
- a ranking data composing means for composing the ranking values, which are produced within said ranking data producing means and said CM-use ranking data producing means;
- a threshold value inputting means for inputting a threshold value indicative of a ranking value of a frame to be reproduced therethrough;
- and
- a reproducing means for determining a reproducing section among said contents upon basis of the threshold value inputted and said ranking value composed, and for reproducing an abridgement corresponding to said reproducing section, wherein
- said CM-use ranking data producing means determines a ranking value of said commercial message therein, to be higher than said threshold value.

A method for displaying an abridgement for a video recording/reproducing apparatus, comprising the following steps of:
- a step for inputting contents;
- a step for evaluating a plural number of frames, upon basis of a parameter included in said contents;
- a step for producing ranking value for each of said frames, upon basis of a result of said evaluation;
- a step for extracting a commercial message from said contents;
- a step for producing a ranking value of the commercial message, which is detected in said above-mentioned step;
- a step for composing the ranking values of frames and the ranking value of said commercial message;
- a step for inputting a threshold value indicative of a ranking value for a frame to be reproduced;
- and
- a step for determining a reproducing section among said contents, upon basis of the threshold value inputted and said ranking value composed, and for reproducing an abridgement corresponding to said reproducing section, wherein
- a ranking value of said commercial message is determined to be higher than said threshold value.
