[0012]
Next, the operation of the DVD player will be described with reference to the flowcharts of FIGS.
When the user wants to play a movie recorded on the DVD 2, the DVD 2 is set in the DVD player 1.
When setting the off-timer, the power key 21a is operated with the key input unit 21 of the remote controller 20 shown in FIG. 2, and then the off-timer key 21g is operated.
In response to this key operation, the control unit 19 shifts to an off timer setting mode, reads video / audio information and related recording information from the recording track of the DVD 1, and sets the off timer on the screen of the monitor 11 shown in FIG. Display prompting characters.
The user who sees the displayed contents can specify the type of the off-timer function he / she wants to stop reproduction by the number of operations of the off-timer key 21g.
[0013]
In this off-timer setting mode, the control unit 19 first determines whether or not the off-timer key 21g has been operated once (step S1), and when it has been operated once, requests input of a stop time on the screen. Characters to be used, blanks, etc. are displayed (step S2).
Here, after the user inputs a number indicating a stop time such as 30 minutes or 1 hour in each blank and then operates the memory key 22b, each data is transmitted from the transmission unit of the remote controller 20. Then, when received by the receiving unit of the DVD player 1, the control unit 19 stores it in the memory 16 (step S3).
Thereafter, a character such as “off timer setting completion” is displayed on the screen of the monitor 11 (step S10), and the off timer setting mode is exited.
On the other hand, when the user does not input the off-timer key 21g within a predetermined time, it is determined whether or not this key has been operated twice (step S4). Characters, blanks, etc. that request the input of the title number are displayed (step S5).
[0014]
Here, when the user inputs the number of the title number indicating the stop position in each blank and then operates the memory key 22b, this input data is stored in the memory 16 (step S6).
Then, the characters “off timer setting completion” are displayed on the screen of the monitor 11 (step S10), and the off timer setting mode is exited.
On the other hand, if the user does not input the off-timer key 21g within a predetermined time, it is determined whether or not this key has been operated three times (step S7). Characters, blanks, etc. requesting the chapter number of the title number are displayed (step S8).
When the user inputs a chapter number indicating the stop position in each blank and then operates the memory key 22b, the input data is stored in the memory 16 (step S9).
Then, the characters “off timer setting completion” are displayed on the screen of the monitor 11 (step S10), and the off timer setting mode is exited.
On the other hand, when the user does not input the off timer key 21g within the predetermined time, the off timer setting mode is ended (step S11).
[0015]
Thereafter, the control unit 19 enters processing at the time of setting the off-timer. When the user operates the play key with the key input unit 21, the control unit 19 shifts to the reproduction mode to start the operation of the drive system and A read start command is sent to start reproduction (step S21).
In this reproduction mode, the information on the recording track is read by the optical pickup 4 of the reading unit 6 as the DVD 2 rotates. Then, the reproduced video is displayed on the screen of the monitor 11, and sound is emitted from the speaker 12. Therefore, the user can listen to a movie with a certain title number.
During the reproduction, the control unit 19 monitors the data stored in the memory 16 and determines whether or not the stop setting position is reached (step S22).
That is, when the user has set a stop time such as 30 minutes or 1 hour, the control unit 19 stops the operation of the drive system at the time of counting up after the time counting by the counter 17 is started (step S23).
In addition, the control unit 19 sends an off control signal to the power supply unit 13, opens the switch, and stops the voltage supply to each part of the circuit (step S24).
Thereby, even if the user falls asleep while watching a movie, the reproduction operation is automatically stopped at the set time, and the power supply unit 13 is turned off, so that useless power consumption is avoided.
[0016]
By the way, when the title number that the user wants to stop is set to 1 or 2, the control unit 19 stops the playback operation when the numeric data in the memory 18 matches the title number, and the power supply The unit 13 is turned off (steps S23 and S24).
Therefore, even if the user falls asleep while watching a movie, all the operations are stopped when the movie with a certain title number is finished, so that unnecessary power consumption thereafter is avoided.
If the chapter number of the title number that the user wants to stop is set to 10th or 20th, the control unit 19 stops the playback operation when the numeric data in the memory 18 matches the chapter number. Then, the power supply unit 13 is turned off (steps S23 and S24).
Therefore, even if the user falls asleep while watching a movie, all the operations are stopped in the middle of the movie with a certain title number, so that unnecessary power consumption after that is avoided.
[0017]
In the above-described off-timer setting, the case where playback stop is individually set for input such as time, title number or chapter number has been described. However, input setting by combination of title number and time or chapter number and time is also possible. Is possible.
When setting the playback stop by the title number and time, the screen of the monitor 11 is set so that the combination of both can be input when the off-timer key 21g is operated four times or when the operation is continued for a predetermined time or more. The character prompting input may be displayed and the data may be stored in the memory 18 when the user inputs according to this.
When playback stop is set by chapter number and time, when the off-timer key 21g is operated for a predetermined time or longer, a character prompting input is displayed on the screen of the monitor 11 so that the combination of both can be input. However, the data may be stored in the memory 18 when the user inputs in accordance with this.
Thereby, when the playback stop is set by the title number and the time, the entire operation can be stopped a few minutes after the playback of a certain movie is started.
Also, when playback stop is set by chapter number and time, all operations can be stopped some minutes after the start of playback of a certain movie.
[0018]
In the above embodiment, an example in which the video information reproducing apparatus is applied to a DVD player has been described. However, the video information reproducing apparatus can also be used for a CD player or the like.
Since the popular CD player reproduces the music information recorded on the CD, the user sets the off-timer by operating the dedicated remote controller as described above.
Here, when the off-timer key is operated a predetermined number of times, the type or number of the off-timer is input according to the input request character or blank displayed on the monitor screen. Then, these data are stored in the memory.
Thereafter, the control unit of the CD player performs processing at the time of setting the off timer, and stops all operations at a required stop position.
For this reason, even if the user falls asleep while listening to a certain piece of music, the playback operation does not continue for a long time, so that waste of power consumption is suppressed.
[0019]
【The invention's effect】
