シする危険性があった。In recent years, interest in new media equipment, CATV, home pass systems, etc. has been increasing, and in particular, for home pass systems, various companies and research companies are developing information on transmission methods such as video signals, audio signals, data transmission, channel plans, etc. This is currently being considered by the Board of Directors, etc. Currently, these information transmission methods are still in flux and have not been standardized, but one of the leading transmission methods is that video and audio are modulated in the subband or midband band, and data is transmitted as is in the baseband. The transmission method that transmits data is attracting attention -0 In this transmission method,
As shown in Figure 1, a branch coaxial cable (3) is connected to a branch (2) connected to a coaxial cable (1), and an information output terminal (4) is provided on this branch coaxial cable (3). When the music feed path is formed like this, each information output terminal (4) outputs a modulated video and audio signal (RF multiplied signal (!: data signal 8
Both signals of j′ (baseband signal) can be extracted. However, in this case, there is a concern that the baseband signal will affect the RF signal.
If a V or intercom A device was connected to the I/O signal output terminal (4), there was a risk that stripes would appear on the screen or noise would occur in the audio.

The RF multiplied signal transmitted through the branch (2) and the branch coaxial cable (3) is received by the baseband RF M Ji.
3 At the information output terminal (5), the DC component is cut by the capacitor c1, and the RF multiplied signal can be extracted.
At the baseband signal information output terminal (6), capacitor C
2, the high frequency components are grounded and only the baseband signal can be taken out, which improves mutual interference. However, as it is, when connecting n terminal devices to one outlet, 2 x n information output terminals are required.
7. The pace is larger, which is preferable for practical purposes. Therefore, in the present invention, the information output terminal has a built-in changeover switch for RF trust and baseband signals, and the 97 changeover switch is changed depending on the shape of the connector of the terminal device connected to this information output terminal. It is.
