发明名称 Data Processor
摘要 To detect boundaries between the content of a telecast, for example, and commercial messages, included in the telecast, highly accurately when the user is deleting the commercial messages. A data processor includes: a picture level detecting section, which receives a video signal including a plurality of pictures and detects the signal level of a predetermined one of the pictures based on the signal; a frame memory section for storing the data of the pictures; and a controller for adding index information. The picture level detecting section specifies a video changing point by reference to the respective signal levels of multiple consecutive pictures and the controller adds the index information to a data location, corresponding to the changing point, in a data stream.
