<p>PURPOSE:To simplify user's operation by successively executing the counting-up or counting-down of the start time and end time of stored reserve data by means of a control device and a comparator. CONSTITUTION:A user commands the 30 min counting down of the start time and end time for timer reservation from an input device 1. Thereby, a control device 2 successively reads out reserve data stored in a storage device and supplies the read contents to the comparator 4. The comparator decides whether the picture recording channel data out of the reserve data coincide with received channel data obtained from a channel selection device 7 or not. The comparator 4 compares the data of the start date and time for two reserved data with data obtained from a clock device 6 and outputs an execution command to the device 2. At the time of inputting the execution command, the start/end time data of the read reserved data are changed to the data counted down by 30 min and the updated data are stored in the device 3.</p> |
