New Description: 【New Technology Fields】 This is a kind of audio and video signal distribution technology. In particular, it refers to a video source of a single broadcast host transmitted to a complex array of audio and video broadcasts through a transmission line. Device. [Prior Art] Luyin, video and audio distribution system is a technology that converts and enhances video and audio signals from a single input source to multiple display devices and speakers. In recent years, the application of video and audio distribution systems has become more and more popular. Popularity, common in promotional broadcasts in stores, companies, school briefing devices... or other commercial uses. For example, in the teaching application of the school, the town uses the image distribution technology to enable the simultaneous transmission of video and audio signals from a single input source to the audio-visual equipment at all student seats. The students are ready to receive teaching in their own seats. In addition, it is not affected by the distance of the location's to enhance the quality of teaching. * - · In particular, when applied to computer teaching, the town uses the image distribution technology to allow the teacher's computer face and sound to be transmitted at the same time. To the audio-visual equipment in all student seats (the computer screen and the remaining eight), the students can receive the contents of the teacher's teaching demonstration in the audio-visual equipment in their own seats, and they can immediately perform on their own computers after the teacher demonstrates. Practice 'to speed up the absorption of teaching content. A similar image distribution system includes at least one video playback host, an image distributor, a plurality of display devices, and a plurality of transmission lines. Wherein, the image 24714 dispenser has one input end and a plurality of output ends; as shown, the two ends of each transmission line can be respectively connected to the output end of the image distributor and the audio-visual equipment, and become the image distributor and the audio-visual equipment. Transmission channel. As for the conventional AV Splitter, the 4 pori: or 8 port design 'that is, each of the AVSplitter's p〇rt can only connect a group of audio-visual equipment, which is relatively applicable. The number of audio-visual equipment, as well as the scalability of the system, will of course be limited by the number of transmissions and receivers (AV Splite). In addition, the conventional audio-visual distributors use DB15 cables with limited length, if audio-visual equipment and audio-visual distributors When the distance is far away, it is relatively difficult to exceed the standard wire, so it is less flexible in practical application. Eight [new content] In view of this, the creation is to provide a video signal broadcast that can easily increase the number of extensions of audio-visual equipment. The device is its main purpose. As a result, the audio and video signal broadcasting device of the present invention basically uses the = number converter to connect and play the video signal of the host computer, and then at least two transceivers respectively correspond to the audiovisual equipment corresponding thereto.

In an embodiment, The transceiver 40 is electrically connected to the corresponding audio-visual equipment 20 through the transmission line 50 through the image output interface 44 and the sound source wheel-out interface 45. The transceiver 40 located at the rear end is transmitted through the transmission line 50 from the first input interface 42 thereof. The front end transceiver 40 is electrically connected to the front end of the transceiver 40 through the first input interface 42 and the third output interface of the at least one signal distributor 60. The second input interface 62 of the at least one signal distributor 60 is electrically connected to the first output interface 33 of the signal converter 30 via the transmission line 50. In the structure of the four figures, the at least one signal distributor 60 electrically connected to the signal converter 3 can be electrically connected to the other signal distributor 60 by using the third output interface 64, and then through other The signal distributor 6 is connected in series with the plurality of transceivers 40, and then connected to the audio-visual equipment 2 in a mesh-like manner. Not only can the number of audio-visual equipments be increased, but the configuration of the audio-visual equipment is relatively more flexible. . In the implementation, the at least one signal distributor 6 can be further integrated: an image output interface 66 for the external transmission line 50, a source output interface 67 for the external transmission line 5, and an image output of the signal distributor 6 The interface 66 and the audio source interface 67 are electrically connected to the second input interface 62, so that the signal distributor 60 has the function of directly connecting the audio-visual equipment 2; of course, the image output interface of the signal distributor 60 66. The audio output interface 67 is preferably electrically connected to the second input interface 62 through a signal compensation circuit 681. The signal compensation circuit 681 can automatically detect the length of the line transmission line 5 and the length of the wire. To achieve better signal transmission quality? Similarly, the first signal selection circuit 34 and/or the second signal selection circuit 48 and each of the third signal selection circuits 65 are electrically connected to a signal compensation circuit 351, 491, 68A and an uplink detection circuit 352, respectively. And 492, 682; and the second encoding circuit 47 and the first input interface 42 are electrically connected to each other with a speaker circuit 491 'signal compensation circuit 3 卩 1, 4 91 can pass through the automatic transmission line transmission line The 50-wire length compensates for the signal potential to achieve better signal transmission quality. Of course, the first output interface 33, the second output interface 43, the third output interfaces 64., the first input interface 42, and the second input interface 62 are respectively provided with a Category 5 mesh. The M424716 port of the CAT 5 cable specification can use the Category 5 network cable (CAT 5 cable) as the main channel for signal transmission. Not only the wire is easy to obtain, but also the length of the wire is not. limit.
