摘要：
In a channel selecting device for a CATV terminal unit, a channel code table is stored in a ROM of the terminal unit, and only a code arrangement in the channel code table is written in a RAM, whereby the rewriting data is compressed, the time required for the data writing operation is reduced, and the area occupied by the RAM decreased.
