(EN) Equipment and method for automatic detection of television advertisement
(ZH) 自动检测电视广告的装置及其方法
Abrégé
(EN)
This invention relates to a device for automatically detecting TV advertisements including a video frame buffer memory for storing a first set of video frames and a second set of video frames with obviously different lens switching frequency from the first, a video lens switch detection and computation device for fetching the two sets video frames stored in said buffer memory and computing the last frame of the first before switched to the second as the cue key frame and computing the correlation between the received frame and the cue key frame, a cue signal generation device generating cue signals when the correlation between the received frame and the cue key frame is larger than or equal to the pre-designed threshold value and a control device controlling the operations of the compute of the lens switch detection and operation of the computing device. A method is disclosed for automatically detecting TV advertisements.

(ZH)

本发明公开一种自动检测电视广告的装置,包括:视频帧缓存器,用于存储电视机接收的第一组视频帧和镜头切变频率与第一组视频帧明显不同的第二组视频帧;视频镜头切变检测和计算装置,用于读取所述视频帧缓存器中存储的第一组和第二组视频帧,并计算第一组视频帧向第二组视频帧切变前的第一组视频帧的最后一帧作为提示关键帧,以及计算新接收的视频帧与提示关键帧之间的相关性;提示信号产生装置,用于在视频镜头切变检测和计算装置检测到所述新接收的视频帧与所述提示关键帧之间的相关性大于或等于预定的阈值时,产生提示信号;和控制装置,用于控制视频镜头切变检测和计算装置执行读取,计算的操作。还公开一种自动检测电视广告的方法。
