Abstract
본 발명은 영상패턴 검출장치를 응용하여 텔레비전 광고채널을 검출하여 비광고채널로 자동절환하는 텔레비전 광고채널의 비광고채널로의 자동절환장치 및 방법에 관한 것으로서, 영상패턴 검출장치는 피크검출부; 검출된 신호를 저장하는 메모리부; 영상신호의 상관도를 검출하는 상관도검출부; 및 영상패턴 유무를 판단하는 패턴판단부를 포함하고, 비광고채널로의 자동절환장치는 입력영상신호를 제1튜너;제1튜너신호에서 자막검출하는 제1자막검출;제2튜너;제2튜너신호에서 자막검출하여, 있으면 제2튜너의 튜닝주파수를 변경하는 신호를 출력하는 제2자막검출부; 및 제1및 제1자막검출부의 출력신호의 제어로, 자막없는 영상신호를 출력하는 채널선택부를 포함하고, 자동절환방법은 영상신호 튜닝단계; 영상화면 분할단계; 자막검출 단계; 제2채널 자막이 잇으면 제2채 널주파수 변경단계; 자막 없는 채널중 제1채널을 우선으로 출력하는 단계를 포함함을 특징으로 한다.The present invention relates to an apparatus and method for automatically switching a television advertisement channel to a non-advertisement channel by detecting a television advertisement channel by applying an image pattern detection apparatus, and automatically switching to a non-advertisement channel. A memory unit for storing the detected signal; A correlation detector detecting a correlation between video signals; And a pattern determination unit determining whether an image pattern exists, and the automatic switching device to a non-advertising channel includes: a first tuner for detecting an input video signal; a first subtitle detection for detecting a caption from the first tuner signal; a second tuner; a second tuner A second subtitle detector for detecting a caption from the signal and outputting a signal for changing a tuning frequency of the second tuner, if any; And a channel selector for outputting a video signal without subtitles under the control of output signals of the first and first subtitle detectors, the automatic switching method comprising: a video signal tuning step; Splitting the video screen; Caption detection step; Changing a second channel frequency if there is a second channel subtitle; And outputting the first channel among the channels without subtitles first.
본 발명에 의하면 광고방송시의 텔레비전 채널 절환을 비광고채널으로 자동으로 해 줌으로써 사용자의 편의를 도모할 수 있다.According to the present invention, a user's convenience can be attained by automatically switching a television channel to a non-advertising channel during commercial broadcasting.
