Abstract

PURPOSE:To make the time prolongation of a timer video recording simple without changing the broadcasting system of a broadcasting station. CONSTITUTION:This system is provided with a system control circuit 1 controlling the whole of a system, a motor control circuit 2 driving a motor, a display circuit 3 displaying prolongations and cautions, an input circuit 4 performing the inputtings of prolonging information and a tape running system circuit 5 monitoring a tape running state. When a prolonging information is inputted from the input circuit 4, the system control circuit 1 prolongs a reservation completing time and also makes the motor control circuit 2 operate and calculates the remaining time of a tape with information from the tape running system circuit 5 and then displays a caution on the display circuit 3 in a case that the video recording of the whole of a reserved time is impossible and controls a tape speed optimally in a case that the recording is possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of changing a recording time when there is a possibility of changing the time of a reserved program in a recording device having a timer function.

[0002]

2. Description of the Related Art As to a time changing method for timer recording, for example, as described in Japanese Patent Laid-Open No. 03-89786, a program code of a broadcast program is recorded on a VCR and a program code transmitted by a broadcasting station is used. It is possible to extend the program by transmitting a control signal from the broadcasting station, as described in Japanese Patent Laid-Open No. 02-294957, which corresponds to the method of changing the broadcast time by recording only the matched program. There is a method to do.

[0003] These conventional techniques require a drastic change in the broadcasting system and are not currently in practical use. Therefore, in the conventional home-use VCR, when the reserved program time may be changed due to baseball broadcasting or the like, it is necessary for the user to set a long program reservation time in advance and record it.

[0004]

In the above-mentioned prior art, when it is found that there is a possibility that the baseball broadcast will be extended after the program reservation is made, the program reservation is canceled once and the recording time is made longer. It was necessary to perform the complicated operation of resetting the reservation. In addition, there is a problem that it is necessary to check the remaining time of the tape because the recording is performed for a long time.

An object of the present invention is to provide a system capable of easily extending a reservation time and recording without paying attention to the remaining time of a tape when there is a possibility that the program time may be extended due to a baseball broadcast or the like. It is in.

[0006]

SUMMARY OF THE INVENTION The above-mentioned object is to provide a recording apparatus equipped with a system control circuit for controlling the entire system, an input circuit for inputting extension information to the system control circuit, and a tape running system circuit for monitoring the running state of a tape. When the extension information is input from the device user to the system control circuit by a button or the like, the control to automatically extend the recording end time for a certain period of time and the tape remaining at the time of obtaining the extension information by the information from the tape running system circuit Calculate the amount of time, if the remaining tape time is shorter than the reserved recording time, slow down the recording speed from the middle of recording, and if the remaining tape time is shorter than the reserved recording time even if the recording speed is slow, This can be achieved by controlling to output a warning display or a warning sound.

[0007]

In the above method, the device user can operate the button or the like only when the user intends to extend the program, so that the extension of the recording end time or the remaining time of the tape is automatically calculated and the extended portion can be recorded. The recording speed is controlled and a warning is displayed even if the extension cannot be recorded, so the recording can be easily extended, improving usability.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. In FIG. 1, 1 is a system control circuit, 2 is a motor control circuit, 3
Is a display circuit, 4 is an input circuit, and 5 is a tape running circuit.

Next, the operation of FIG. 1 will be described with reference to the flowchart of FIG.

The input circuit 4 has an extension button, and the system control circuit 4 is in an input standby mode for checking whether the extension button has been input (11). When the extension button is input, first, it is checked whether or not there is a reservation (12). If there is no reservation, the system control circuit 1 displays a warning of no reservation on the display circuit 3 (13). If there is a reservation,
The presence or absence of tape is checked (14). If there is no tape, the system control circuit 1 displays a warning of no tape on the display circuit 3 (15). When there is a tape, the system control circuit 1 displays on the display circuit 3 that the extension mode is being checked (16). After that, a certain fixed extension time ΔT is added to the reservation end time T (17), and the system control circuit 1 operates the motor control circuit 3 to set the tape remaining amount calculation mode to the tape running system circuit. Based on the information from 5, the remaining time T3 of the tape is calculated in the triple mode conversion (18).

The system control circuit 1 determines the tape remaining time T
And the reservation time T + ΔT are compared (19). T3 <T + △
In the case of T, the system control circuit 1 subtracts the extension time ΔT from the reserved time T + ΔT (20), turns off the extension mode checking display to the display circuit 3 (21), and displays the extension impossible (22). ). If T3> T + ΔT, the system control circuit 1 compares the remaining tape time T3 / 3 when recording in the standard mode with the reserved time T + ΔT (23), and then T3.
When / 3 <T + ΔT, while watching the remaining time of the tape, the automatic recording mode is set to shift the recording speed from the standard to triple from the middle of recording so that all reserved programs can be recorded on the tape (24). When T3 / 3> T + ΔT, the recording speed is standard (25).

Thereafter, the system control circuit 1 displays on the display circuit 3 that the extension mode has been entered, and shifts to the reservation standby mode.

According to the present embodiment, the user can simply extend the reservation end time by pressing the extension button when he / she wants to extend the reservation end time, and the remaining tape amount can be reduced. The device makes all the judgments without you having to be aware of it, which improves usability.

[0015]

According to the present invention, it is possible to extend the program reservation without changing the code from the broadcasting station and without being aware of the remaining tape amount only when the user of the apparatus intends. Be peeled off.
