<p>PURPOSE:To dispense with reservation setting at every time by rewriting channel selection information by using a memory means, and performing channel selection by automatically switching a prescribed channel in memory at every designated time. CONSTITUTION:The memory means 2 writes information received when a pulse is generated on the memory of the memory means 2 by a memory write pulse generated at every time interval designated by a timer means 1 by linking with a control means and a tuner to perform the channel selection. The channel selection information such as an operating voltage Vt and a channel number, etc., is inputted to the tuner 4, and the tuner 4 is automatically switched to a designated channel written on the memory at a time designated by the timer means 1 under the control of the control means 3. In such a case, when certain change is applied to the channel selection information written on the memory means 2, the content of the memory means 2 is rewritten to the channel selection information after change by the control means 3.</p> |
