In addition, recording a broadcast program using a recording device from an early stage, and reproducing and using a playback device has been performed, but the volume of the recording tape is large, and mold is generated due to moisture. So now it has been deceived from the flow of the times.

Research and development have resulted in the creation of discs such as VCD and DVD. VCD and DVD reproduce video by a playback device. However, even if it is VCD or DVD, video is displayed by transmitting a video signal to a display device through a transmission cable. As an early video signal transmission cable, DVI (Digital Video Interleaved) was used, and an arithmetic method for compression / decompression was performed by Intel i750 VLSI (registered trademark). Since the DVI transmission cable can only transmit video and not sound, it is necessary to combine an amplifier, and the installation of the cable is troublesome and inconvenient.

In order to solve the above-described drawbacks in signal transmission according to the prior art, a high definition multimedia interface (HDMI) signal transmission system has been researched and developed. For HDMI, HDCP (High Bandwidth Digital Content Protection), which is a copy protection mechanism developed by Intel in 2002, is used. HDMI not only supports digital video signal standards such as SXGA, UXGA, SDTV, HDTV, but also CD, DVD-Audio, Dolby, matching high-analysis video signals and multi-channel audio signals to a single all-digital interface. Digital audio signal standards such as Digital / DTS can also be transmitted, and simultaneously 8-channel compressed or uncompressed digital audio signals can be transmitted. HDMI can provide a color depth of up to 48 bits for each primary color, the transmission speed reaches 5 Gbps, and high-quality digital signals that are not compressed can be transmitted.

As an information society, exhibitions, briefing sessions, and other various events are held. In these events, audio output devices and large monitors are generally used to attract visitors by video and audio effects. It has an excellent advertising effect and is supported by many users. When signal transmission is performed using an HDMI cable, the signal transmission cable and installation time can be saved, and the effect of video / audio reproduction is excellent. However, when the transmission distance exceeds 10 meters, the signal attenuates when the transmission distance exceeds 10 meters. In an event venue such as an exhibition or a briefing session, since the distance between the playback device and the monitor and the audio output device is 10 meters or more, the signal is attenuated, resulting in a problem that the video / audio playback effect is not excellent.

Accordingly, it has been desired for those skilled in the art to improve how to solve the problem of signal attenuation when signal transmission between a playback apparatus and a monitor is performed using an HDMI cable.

In view of the above problems, the inventor of the present invention collects related materials, repeats trial production and correction, finally improves the quality and effect at the time of signal transmission, is convenient for carrying, and transmits signal according to the situation in the field. A signal conversion box that can change the installation position of the cable was devised.
