Description

Video signal transmission device and transmission method

The present invention provides a transmission device and a transmission method for audio and video signals, in particular, a transmission device and a transmission method for playing audio and video signals of electronic products, and transmitting the sensed signals through the electronic product to the playback device for playback. To achieve the purpose of document, video and audio interaction.

According to the digital technology era, many electronic and electrical products are also designed towards the digital image mode. In addition to electronics and electrical products, some books, story books, teaching books, etc. will also pass through the audio-visual teaching mode. Using pre-recorded discs for teaching and practice, many people learn more skills through the guidance of CD-ROM teaching, while some teaching books for young children such as juniors or kindergartens use optical pens to create sound effects. The files, together with the images, photos or texts on the audio books, are scanned by the optical pen, and then broadcasted, for reading and audio teaching, and can attract young children to pay attention to the sounding and teaching of the optical pen, and change the tradition through the teacher. The monotonous curriculum of the teaching mode of the class can improve the teaching effect, so the application of audio books is becoming more and more common.

However, after all, audio books only have the function of sound playback, and then the images, photos or texts on the books are matched with the single teaching method, which can not reach the majority of young children, diversified teaching mode, still in practical application. There are some inconveniences and problems, such as:

(1) The audio book clicks on the photo, image or text on the book through the optical pen to produce a voice sound effect, guiding the young child to learn, and can only be carried out for a single teaching mode. It is not easy to teach a plurality of young children at the same time. It is easy to be restricted.

(2) Audio books can only be broadcasted through optical pens. They can't achieve the effect of interacting with users. They are more monotonous and less hot when used, and it is not easy to achieve long-term guidance and practice.

Therefore, how to solve the problem that the use of the known audio books is limited, can not be used by many people at the same time, and can only be heard through the optical pen, and can not produce interactions, such as the inventor and the industry. The direction that relevant manufacturers are eager to study and improve.

Therefore, in view of the shortcomings and shortcomings of the above-mentioned vocal books, the inventors collected relevant information, and through multi-party assessment and consideration, they have been designing such a concept through continuous conceiving and revision through years of experience in the industry. The patent for the invention of the transmission device and transmission method for video and audio signals that achieves a variety of interactive learning effects through the AV signal transmission device, the multimedia video playback device, and the simultaneous playback of video and audio video.

The main purpose of the present invention is to initialize the system of the AV signal transmission device, wait for receiving the value of the video and audio number of the external electronic product, and determine whether the value of the video and audio number is corresponding to the value of the video and audio number through the built-in processor. Then, according to the received video signal mode, perform the corresponding function search operation, and select to perform the ordinary point reading mode function search, the game mode function search or the video play mode function search, and the corresponding application can be started according to the search result. And through the playback device for audio and video playback, the playback end, the audio and video signal transmission device enters the waiting for receiving state, and realizes the interactive application function of converting the electronic product signal into the audio and video playback effect.

The secondary object of the present invention is that the video signal transmission device is electrically connected to a playback device (such as a video display screen or a speaker) for playback, and has a wide range of display functions for interactive interaction by most users. Guidance, practice.
