Next, the operation of the reservation recording / playback control apparatus in the televideo according to the present invention configured as described above will be described with reference to the flowchart of FIG. 3.

First, the control unit 12 receives a control function from the control function setting unit 10 (step 300), and the control unit 12 determines whether the received control function is a reserved recording function (step 310). If the control function is not the scheduled recording function, the corresponding operation is performed (step 320).

On the other hand, if the currently received control function is a reserved recording function, the OSD processing unit 38 is controlled to display a password input request message (see FIG. 4) (step 330). Accordingly, the user inputs a password, whether correct or inaccurate in response to the displayed message, and the entered password is stored in the input password storage unit 30 (step 340). Then, any reservation is made. The recorded data is also stored in the reserved recording data storage unit 16, and the control unit 12 determines whether the scheduled recording start time is reached based on the signal from the time display unit 52 (step 350).

As a result of the determination, when the scheduled recording start time arrives, the above-described general reserved recording operation is performed based on the stored reserved recording data (step 360), and the ID code detector 48 is controlled to control the broadcast program currently reserved. Detect an ID code (broadcast program type) for the detected ID code, and the detected ID code is applied to the control unit 12. The control unit 12 internally, for example, if the detected ID code is an adult code. A flag status register is set to 1, and the flag status register is set to 0 when the detected ID code is a youth code.

In this way, when the reserved recording end time is reached (i.e., YES in step 370), it is determined whether or not a playback command is input after ending the current reserved recording operation. (Step 380).

As a result of the determination, if a playback command is input, it is determined whether the current reserved recording program is adult (step 390). If it is for teenagers (for example, if the flag status register is 0), it is played back regardless of the input password. (Step 400).

On the contrary, in the case of adult use (for example, when the flag status register is 1), it is determined whether the password currently stored in the input password storage unit 50 is correct data (step 410). While it is played back (step 420), if not accurate data is not played (step 430).

According to the present invention as described above, if a password is inputted first during reservation recording, then general reservation recording data input is performed, and if a reservation recording operation is started based on the reservation recording data, the adult / youth for the broadcast program currently reserved is recorded. If the broadcast program to be played is adult only at the end of the reservation recording, the inputted password must be correct. Therefore, a specific layer (i.e., an adult broadcast program) is specified. Even if the youth group has made a reservation recording, it cannot be reproduced.
