Abstract: A control method and device of a video signal combined with interactive control data are proposed, wherein interactive control data are added into or extracted from a video signal. The adding method adds the interactive control data into the front and rear blocks in the video signal exceeding the image display area. The image display area means a frame in the video signal. The front block means a plurality of image scan lines in front of each frame, and the rear block means a plurality of image scan lines behind each frame. Similarly, the extraction method extracts the interactive control data from the front and rear blocks exceeding the image display area.

Abstract: The present invention provides a data exchange and mating method of a handheld interactive device. The handheld interactive device comprises a personal database, a transmission/reception unit, an interpersonal database, a mating database, an analyzing and mating unit, and an output unit. The data exchange and mating method comprises the steps of: connecting to a handheld interactive device of another person and receiving the personal data of the other person; storing the personal data of the other person into the interpersonal database; comparing and analyzing the personal data of user and the personal data of the other person with the mating data of personality and compatibility to generate a mating result; and displaying the mating result on the output unit.
