591951 V. Description of the invention (1) 1 · [Technical field to which the invention belongs]: The present invention relates to a method and device for controlling video signals combined with interactive control data, and in particular, to hide interactive control data in general video signals. When the video signal is played, an interactive control signal is transmitted synchronously to control another interactive device to trigger its response and its device. 2 [Previous technology]: Due to the advancement of computer technology, many interactive teaching software, game software or entertainment software are loved by consumers, but they must be interactively reacted by personal computers, and media for video playback (Yes / TV, VCR or DVD player ... etc.) It is difficult to achieve interactive control response. At present, there are not many applications for interactive control on video signals, mainly because it is not easy to achieve, and if a new format is reformulated, the compatibility with general video playback or display media will be affected; but if it can be used in Adding interactive control data to general video signals will surely extend many applications. For example, when we play a children's education video program, we can control the toys in front of the TV to interact with the children to learn. For example, it can be made into an interactive English teaching video. In the video, the teacher teaches an English sentence, and the relevant answers will be transmitted to the learning machine next to the student. The student can practice the answer to the learning machine. If the answer is wrong, the teacher in the movie It will repeat the teaching until the student learns, then the learning machine controls the video player to play the next sentence. Therefore, the inventor of the present case is able to comply with the existing video signal format and recording media storage format, and can generate interactive video media.
