<p>PROBLEM TO BE SOLVED: To facilitate addition and change of additional functions such as a signal process, a signal conversion, etc., and facilitate size reduction and maintenance. SOLUTION: A basic block B1 is attached to the bottom of the terminal board main part 1 of a wiring terminal board A, and furthermore a plurality of functional units are housed in the functional unit housing space 1a of the wiring terminal board A. The basic block B1 is constituted of a non-closed cable connection unit 3, an U/V signal I/O unit 4, a BS signal I/O unit 5, a mixing unit 6, a branch/composite unit 7, a BS-U/V signal I/O unit 8 and a distribution unit 9. Therefore, additional functions such as signal process, signal conversion, etc., can be provided outside the basic block B1 , and as a result, additional functions can easily be added and changed and size reduction and maintenance is facilitated.</p> |
