Description

  The present invention has a configuration in which, for example, a VCR or DVD recorder and a television receiver are connected, and video data and audio data of digital television broadcasting such as CS broadcasting and BS broadcasting are transferred to a hard disk or DVD by a VCR or DVD recorder. The present invention relates to a recording system having a timer function capable of performing recording registration of recording time when recording.

  In recent years, a recording / reproducing apparatus using a hard disk has been proposed as a recording medium for recording the video data of the digital television broadcast in place of the conventional video tape, and this recording / reproducing apparatus generally has a timer function. ing. As the timer function, when a recording key (hereinafter abbreviated as REC key) is pressed, a normal recording operation function for starting recording of a broadcast program at that time and a normal recording operation are performed. The remaining recording time is set by pressing the REC key in a state where the recording is performed, and a one-touch recording function for recording until the recording time elapses, and a broadcast program is reserved, and the recording operation is performed at the reservation start time. A program reservation function that starts and ends the recording operation at the reservation end time.

  As shown in FIG. 6, the one-touch recording function temporarily stores the recording time of 30 minutes in the memory when the REC key is pressed once after the normal recording operation is started by pressing the REC key. The recording operation is set to end after 30 minutes from the current time, and the recording time is further extended by 30 minutes by pressing the REC key again to update and register to 1 hour. By continuously pressing the REC key, the recording time obtained by extending the recording time by 30 minutes is updated and registered. In the case of the recording / playback apparatus shown in FIG. 6, when the REC key is pressed 16 times from the time when the normal recording operation is started, the maximum recording time of 8 hours is set and registered. When the pressing operation is performed once more, the recording time setting is deleted and the normal recording operation is resumed, and the recording time setting cycle ends. When the REC key is pressed from this normal recording operation state, the above-described recording time setting cycle is repeated again.

On the other hand, the program reservation function sets the current time if a reservation program consisting of a program number, reservation date, recording start time, recording end time, channel and operation mode is set, for example, by key input of a remote control transmitter The recording operation is automatically started when the recording start time is reached, and the recording operation is automatically ended at the recording end time. As the program reservation function, for example, when a baseball broadcast is extended or a special program is broadcast, and the scheduled time for a later broadcast is deferred, the time is set every time the plus one-touch shift key is operated once. By adding 10 minutes to the shift amount and subtracting 10 minutes from the time shift amount each time the minus one-touch shift key is operated once, both the recording start time and the reservation end time can be moved forward and backward simultaneously with a very simple operation. A video tape recorder having a timer function that can be shifted has been proposed (see, for example, Patent Document 1).
JP-A-5-274743

  However, in the setting method of the recording time in the one-touch recording function of FIG. 6, for example, when setting the recording time of 3 hours, if the REC key is operated once and the recording time is 3 hours and 30 minutes, In order to correct the set recording time to 3 hours, the REC key must be operated 16 times to perform a complicated operation for making one cycle of the recording time setting cycle. On the other hand, when a relatively long recording time such as 8 hours or 7 hours is set, it is necessary to repeat the operation of the REC key many times such as 15 times or 16 times after the normal recording operation. It is troublesome to perform many operations while paying attention not to do so.

  On the other hand, the program reservation function disclosed in Patent Document 1 is capable of shifting both the recording start time and the reservation end time back and forth at the same time with a simple operation. If you want to use it to set the recording time in the one-touch recording function, plus and minus one-touch shift keys must be separately provided for the recording time setting in the one-touch recording function, and a control program executed by the microcomputer must be separately provided, which increases costs. It becomes.

  The present invention has been made in view of the above-described conventional problems, and can easily and quickly perform a recording time setting operation in the one-touch recording function while avoiding an increase in cost by using an existing configuration. It is an object of the present invention to provide a recording system having a timer function.

  In order to achieve the above object, a recording system with a timer function according to a first aspect of the present invention includes a normal recording function for starting recording of a broadcast program when a recording key is operated, and the recording during the normal recording operation. A recording system with a timer function having a one-touch recording function for setting and registering the remaining recording time by further operating a key, and a key input unit having various operation keys including at least the recording key; A control unit that controls the entire apparatus by executing a control program based on a command signal input from a key input unit, a memory that temporarily stores a set recording time under the control of the control unit, and measures a predetermined time Record video data and audio data of timer circuit section and broadcast program on recording media A recording processing system, and the control unit sets and registers a minimum recording time in the memory when the recording key is operated in a state where the one-touch recording function mode is set, and the recording key is operated. When the operation is performed, a new recording time obtained by sequentially adding a predetermined time to the recording time stored in the memory for each operation is newly calculated and registered in the memory, while the mode of the one-touch recording function is set. When the recording key and the specific key existing in the key input unit are simultaneously operated in the state, the maximum recording time is set and registered in the memory, and further, when the recording key and the specific key are operated simultaneously, For each operation, a new recording time is calculated by sequentially subtracting a predetermined time from the recording time stored in the memory. After the mode of the one-touch recording function is set and the first recording time is initially set in the memory after the mode of the one-touch recording function is set, the timer circuit unit starts the timing operation, and the time counting is performed. And a function of controlling the recording processing system so as to end the recording operation when the time reaches the recording time stored in the memory.

  The recording system with a timer function according to the second aspect of the present invention includes a normal recording function for starting recording of input video data by operating a recording key, and the remaining operation by further operating the recording key during the normal recording operation. A recording system with a timer function having a one-touch recording function for setting and registering a recording time, and a control unit that controls the entire apparatus by executing a control program based on a command signal input from an operation unit, the one-touch recording When the recording key is further operated with the function mode set, a new recording time obtained by sequentially adding a predetermined time to the recording time stored in the memory for each operation is calculated and stored in the memory. While performing update registration, the one-touch recording function When the recording key and an existing specific key in the key input unit are operated at the same time with the recording mode set, new recording is performed by sequentially subtracting a predetermined time from the recording time stored in the memory for each operation. It has a control function to calculate the time and perform update registration to be stored in the memory, and to terminate the recording operation when the recording time stored in the memory has elapsed since the mode of the one-touch recording function is set. It is characterized by that.

  According to a third aspect of the present invention, there is provided a recording system with a timer function, wherein the control unit according to the second aspect of the invention performs control to calculate a new recording time when the recording key and the specific key are operated simultaneously. Instead of this, control is performed to calculate a new recording time when the recording key of the remote control transmitter and the existing specific key are continuously operated within a certain time.

  According to a fourth aspect of the present invention, there is provided a recording system with a timer function according to any one of the first to third aspects, wherein a cursor down key is used as the specific key.

  The recording system with a timer function according to a fifth aspect of the invention includes a normal recording function for starting recording of input video data by operating a recording key, and a remaining operation by further operating the recording key during the normal recording operation. A recording system with a timer function having a one-touch recording function for setting and registering a recording time, and a control unit that controls the entire apparatus by executing a control program based on a command signal input from an operation unit, the one-touch recording When the cursor up key of the operation unit is operated with the function mode set, a new recording time is calculated by sequentially adding a predetermined time to the recording time stored in the memory for each operation. Update registration to be stored in the one-touch recording function When a cursor down key of the operation unit is operated in a state in which a recording mode is set, a new recording time is calculated by sequentially subtracting a predetermined time from the recording time stored in the memory for each operation. And a control function for ending the recording operation when the recording time stored in the memory elapses from the setting of the mode of the one-touch recording function.

  According to the first aspect of the present invention, each time the recording key is operated in a state where the one-touch recording function mode is set, a new recording time is calculated by sequentially adding a predetermined time to the recording time stored in the memory and stored in the memory. Every time a recording key and an existing specific key are operated at the same time with the recording time up setting cycle to be updated and the mode of the one-touch recording function set, the predetermined time is sequentially subtracted from the recording time stored in the memory. The recording time down setting cycle for calculating the new recording time and updating and registering it in the memory is included. Therefore, when the recording time setting operation is performed based on one of the setting cycles, the key is pressed once. If you make a mistake in pressing excessively, correct the recording time to the desired recording time by operating the key corresponding to the other setting cycle once. For example, when setting a long recording time such as 8 hours or 7 hours 30 minutes, the maximum recording time is set by simultaneously operating the recording key and a specific key, and then the recording time down setting cycle is set. By performing the recording time setting operation based on this, a desired long recording time can be set very quickly.

  Therefore, in this recording system with a timer function, it is possible to quickly set a desired recording time with a much easier operation compared to the conventional recording time setting method, and to record an existing specific key. Since it is also used for setting the time, the above function can be obtained only by changing a part of the control program executed by the control unit, so that the cost is not increased.

  According to a second aspect of the present invention, a recording time up setting cycle for calculating a new recording time by sequentially adding a predetermined time to a recording time stored in the memory every time the recording key is operated, and updating and registering in the memory, and a recording Each time a key and an existing specific key are operated simultaneously, there is a recording time down setting cycle in which a new recording time is calculated by sequentially subtracting a predetermined time from the recording time stored in the memory, and updated and registered in the memory. Therefore, if an erroneous operation is performed while performing a recording time setting operation based on one setting cycle, the key can be corrected to a desired recording time by operating the key corresponding to the other setting cycle once. In addition, even when setting a long recording time, it can be set quickly based on the recording time down setting cycle. Compared to the standard method, the desired recording time can be set quickly with a much easier operation, and the existing specific key is also used for setting the recording time. Since the above function can be obtained only by changing a part of the control program executed by the control unit, the cost is not increased.

  According to the third aspect of the present invention, compared to the conventional recording time setting method, a desired recording time can be quickly set by a remarkably easy operation, and a part of the control program executed by the control unit In addition to providing an effect that does not incur an increase in cost, it is possible to perform a recording time setting operation using a remote control transmitter. There is an advantage that the recording time setting operation can be performed more easily than the operation.

  In the invention of claim 4, since the cursor down key is also used for the recording time setting operation based on the recording time down setting cycle, the user can definitely remember the key to be operated by the common concept of “down”. There is an advantage that can be.

  In the invention of claim 5, a recording time up setting cycle for calculating a new recording time by sequentially adding a predetermined time to a recording time stored in the memory each time the key is operated, and updating and registering in the memory, and the key Each time it is operated, it has a recording time down setting cycle in which a new recording time is calculated by sequentially subtracting a predetermined time from the recording time stored in the memory and is updated and registered in the memory. If an incorrect operation is performed while performing the recording time setting operation based on this, it can be corrected to the desired recording time by operating the key corresponding to the other setting cycle once, and a long recording time is set. Even in this case, the recording time can be quickly set based on the recording time down setting cycle, so that the desired recording time can be set with much easier operation compared to the conventional recording time setting method. It is possible to set the speed.

  In addition, since the existing key is also used for setting the recording time, the above function can be obtained only by changing a part of the control program executed by the control unit, resulting in high cost. There is nothing. Furthermore, since the recording time can be set based on the recording time up setting cycle and the recording time down setting cycle simply by operating the cursor up key and the cursor down key, respectively, compared to the case where two types of keys are operated simultaneously. Since the operation becomes easier and the simultaneous operation of the two types of keys is not performed, the recording time can be set using the remote control transmitter, so that the key input unit provided on the apparatus main body is operated. In comparison, the recording time setting operation can be performed more easily.

  In addition, both the recording time up setting cycle and the recording time down setting cycle, and the cursor up key and the cursor down key that are also used for the recording time setting operation based on this, have a common concept of “up” and “down”. By being present, there is an advantage that the user can definitely remember two types of keys to be operated.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a recording control system in a recording system with a timer function according to the first embodiment of the present invention. In this embodiment, a configuration in which a DVD recorder is connected to a television receiver is shown. In the drawing, for the sake of easy understanding, in the figure, a well-known configuration that is inevitably provided for practical use is omitted, and is illustrated as a simplified configuration.

  In FIG. 1, a television receiver includes an antenna 1 for receiving television broadcast radio waves, a broadcast receiving unit 2 including a known tuner, an IF (intermediate frequency) amplification unit, a detection unit, and the like, and a known video amplification unit. A video processing unit 3 including a color demodulating unit and a video output unit, a display 4 such as a CRT or LCD for displaying a video signal output from the video processing unit 3, a known audio demodulating unit, and a sound amplifying unit. And an audio processing unit 7 including an audio output unit and the like, and a speaker 8 that converts an audio signal of a television broadcast radio wave output from the audio processing unit 7 into audio and outputs the audio.

  On the other hand, the DVD recorder gives various operation commands to the control unit 9 for controlling each unit, the ROM 10 and the RAM 11 in which the control program and control data to be executed by the control unit 9 are respectively recorded, and the control unit 9. The key input unit 12 and the remote control transmitter 13, the remote control reception unit 14 that receives an infrared command signal transmitted from the remote control transmitter 13 and outputs it to the control unit 9, and the one-touch recording recording mode described later are set. A memory 17 that temporarily stores the recording time and a timer circuit unit 18 that performs a time measuring operation according to a command from the control unit 9 are provided.

  The DVD recorder further includes an MPEG encoder 20 that takes in the video data from the video processing unit 3 and the audio data from the audio processing unit 7 through the interface unit 19 and converts them into digital signals that are compressed by the MPEG2 method. A spindle motor that rotates an optical pickup, a turntable equipped with an optical disk DVD, a spindle servo unit that drives and controls the spindle motor, a thread motor that moves the optical pickup, a tracking thread servo unit that drives and controls the thread motor, and the like A recording / reproducing mechanism 22 for reproducing data recorded on the DVD and recording the data on the DVD, and controlling the digital signal from the MPEG encoder 20 to be recorded on the DVD by the recording / reproducing mechanism 22. Record And a signal processing unit 21.

  In addition, a REC key for designating and inputting a normal recording operation start and a recording time setting registration in the one-touch recording function, respectively, in the key input unit 12 and the remote control transmitter 13 provided in the DVD recorder of the recording system. 12a and 13a, cursor up keys 12b and 13b and cursor down keys 12c and 13c for designating required items in the menu displayed on the display 4 by moving the cursor, and illustration are omitted, but normal recording Various operation keys including a stop key for terminating the operation are provided.

  The above-described configuration of FIG. 1 is an existing configuration generally provided by a conventional recording system with a timer function. In the first embodiment, the above-described existing configuration is used as it is in the ROM 10. The recording time is set easily and quickly in the one-touch recording function only by changing a part of the stored control program. Next, recording time setting processing by the control unit 9 will be described with reference to the flowchart of FIG. In this embodiment, the case where the recording time is set by manual operation of the key input unit 12 provided in the DVD recorder in the recording system is illustrated.

  The control unit 9 waits while monitoring the operation of the REC key 12a of the key input unit 12 (step S1), and controls to start a normal recording operation when determining that the REC key 12a has been operated. (Step S2). That is, when a user who is watching a television broadcast program displayed on the display 4 wants to record a broadcast program being broadcast and presses the REC key 12a, the control unit 9 uses the REC key 12a. Is determined to have been operated, the interface unit 19 is controlled so that the video data from the video processing unit 3 and the audio data from the audio processing unit 4 are input to the MPEG encoder 20, and the MPEG encoder 20, recording signal The processing unit 21 and the recording / reproducing mechanism 22 are driven to perform a normal recording operation for recording video data and audio data on a DVD. Note that video data and audio data may be temporarily stored in the hard disk prior to recording on the DVD.

  Subsequently, after starting the above-described normal recording operation, the control unit 9 determines whether or not the REC key 12a is operated (step S3), and determines whether or not two types of keys described later are simultaneously operated (step S3). S4) and determination of whether or not the stop key is operated (step S5) are sequentially performed. In the present embodiment, the REC key 12a and the cursor down key 12c are designated as the two types of keys.

  When it is determined that either one of the operation of the REC key 12a or the simultaneous operation of the two types of keys 12a and 12c has been performed, the control unit 9 sets the mode of the one-touch recording function, and only the REC key 12a has When operated, the minimum recording time of 30 minutes is set, and the remaining recording time of 30 minutes is temporarily stored in the memory 17 and registered (step S6), while the REC key 12a, the cursor down key 12c, Are simultaneously operated, the maximum recording time of 8 hours is set and the remaining recording time of 8 hours is temporarily stored in the memory 17 and registered (step S7). The timer circuit unit 18 is started to measure the set recording time.

  Next, the control unit 9 starts determining whether or not the recording time initialized in the memory 17 has elapsed based on the time measured by the timer circuit unit 18 (step S8), but determines that the recording time has elapsed. If not, the determination of whether or not the REC key 12a has been operated (step S9) and the determination of whether or not the REC key 12a and the cursor down key 12c have been simultaneously operated (step S11) are repeated.

  When it is determined in the determination process that the REC key 12a has been operated, a new recording time is calculated by adding 30 minutes to the recording time set and registered in the memory 17, and the calculated recording time is stored in the memory 17. Update registration is performed instead of the recording time being registered (step S10), and the process of updating the recording time is performed every time it is determined that the REC key 12a has been operated.

  On the other hand, when it is determined that the REC key 12a and the cursor down key 12c are operated simultaneously, a new recording time is calculated by subtracting 30 minutes from the recording time set and registered in the memory 17, and the calculated recording time is calculated. The recording is updated and registered in the memory 17 instead of the recording time being registered (step S12), and the process of updating the recording time is performed every time it is determined that the REC key 12a and the cursor down key 12c are operated simultaneously.

  However, the timer circuit unit 18 is not reset regardless of whether or not the set recording time is updated, and continues the time measuring operation started when the recording time is initially set. Therefore, the control unit 9 always calculates the remaining recording time by subtracting the time measured by the timer circuit unit 18 from the recording time newly updated and registered in the memory 17, and determines whether or not the remaining recording time becomes zero. That is, it is determined whether or not the set recording time has passed (step S9), and when it is determined that the set recording time has passed, the interface is prohibited so that input of video data and audio data to the MPEG encoder 20 is prohibited. While controlling the unit 19, the driving of the MPEG encoder 20, the recording signal processing unit 21 and the recording / reproducing mechanism 22 is stopped, and the recording operation is ended (step S13).

  Note that the control unit 9 temporarily stores the recording time in the memory 17 and displays the stored recording time as shown in FIG. The display 4 is controlled to be displayed each time through the circuit 23. The display control circuit 23 is an on-screen display circuit, for example. As a result, the user can visually recognize the recording time set by his / her own operation on the display 4 and can reliably set the desired recording time.

  On the other hand, after the normal recording operation is started by the user pressing the REC key 12a, neither the REC key 12a operation nor the simultaneous operation of the REC key 12a and the cursor down key 12c is performed. Then, the normal recording operation is continued, and the recording operation is terminated when the control unit 9 determines that the stop key is pressed (step S5) (step S13).

  FIG. 3 is an explanatory diagram showing the transition of the recording time setting by the control process of FIG. 2 in an easily understandable manner. In the recording system with the timer function, when the REC key 12a is operated after the normal recording operation is started by the operation of the REC key 12a, the mode is shifted to the one-touch recording operation mode and the minimum recording time is 30 minutes. When the operation of the REC key 12a is repeated after the initial setting, every time the operation is performed, a new recording time obtained by sequentially adding 30 minutes is continuously calculated and updated, and the maximum recording time of 8 hours After the setting, when the REC key 12a is further operated, the recording time is set to zero and the normal recording operation is resumed. Thereafter, when the REC key 12a is further operated, the above-described setting of the recording time is repeated. The recording time can be set in the recording time up setting cycle UC. This recording time up setting cycle UC is the same as the recording time setting cycle of the conventional recording system with a timer function described in FIG.

  Further, in the recording system with a timer function, in addition to having the recording time up setting cycle UC, the recording time can be set by the recording time down setting cycle DC. That is, the recording time down setting cycle DC shifts to the one-touch recording operation mode when the REC key 12a and the cursor down key 12c are simultaneously operated after the normal recording operation is started by the operation of the REC key 12a. Then, when the maximum recording time of 8 hours is initialized, and then the simultaneous operation of the REC key 12a and the cursor down key 12c is repeated, new recording is performed by sequentially subtracting 30 minutes each time the operation is performed. If the REC key 12a and the cursor down key 12c are operated at the same time after the minimum recording time of 30 minutes is set after the time is continuously calculated and updated, the recording time is set to zero and the normal recording operation is resumed. Thereafter, when the REC key 12a and the cursor down key 12c are further operated simultaneously, It is intended to repeat the setting.

  By having two types of recording time setting cycles UC and DC in this way, the recording system with a timer function performs the recording time setting operation based on the recording time up setting cycle UC in the one-touch recording operation mode. If, for example, a recording time of 1 hour 30 minutes is to be set, and the REC key 12a is pressed once and an erroneous operation is performed to set a recording time of 2 hours, the REC key 12a The recording time can be corrected back to the desired 1 hour 30 minutes based on the recording time down setting cycle DC by performing only one operation of simultaneously pressing the cursor down key 12c.

  Contrary to the above, if an erroneous operation is performed during the recording time setting operation based on the recording time down setting cycle DC, the operation of pressing the REC key 12a is performed only once. The recording time can be corrected based on the up setting cycle UC. On the other hand, in the conventional recording system with a timer function, as described with reference to FIG. 6, it is necessary to continuously operate the REC key 16 times to make one cycle of the recording time setting cycle when an erroneous operation is performed.

  When a long recording time such as 8 hours or 7 hours 30 minutes is set, the simultaneous operation of the REC key 12a and the cursor down key 12c is 1 after starting a normal recording operation. Only once or twice, a desired long recording time can be set immediately based on the recording time down setting cycle DC. On the other hand, in the conventional recording system with a timer function, when setting a long recording time such as 8 hours or 7 hours 30 minutes, after starting a normal recording operation, the REC key is operated 16 times or 15 times. I must continue.

  Therefore, in the recording system with a timer function, it is possible to quickly set a desired recording time by a remarkably easy operation as compared with the conventional setting of the recording time, and the existing cursor down key 12c can be recorded. Since it is also used for setting the time, the above-described function can be obtained only by changing a part of the control program executed by the control unit 9, so that the cost is not increased. Furthermore, since the recording time setting operation based on the recording time down setting cycle DC also functions as the cursor down key 12c, the common concept of “down” exists on both sides, so that the user can set the recording time down. There is an advantage that it is possible to definitely remember that the key to be used for setting the recording time based on the cycle DC is the cursor down key 12c.

  FIG. 4 is a flowchart showing a recording time setting control process in the one-touch recording operation mode in the recording system with a timer function according to the second embodiment of the present invention. In this embodiment, instead of the key input unit 12 used in the first embodiment, the recording time is set by manual operation of the remote control transmitter 13 provided in the DVD recorder in the recording system of FIG. It has become. In this embodiment as well, as in the first embodiment, the control program stored in the ROM 10 can be stored while using the existing configuration generally provided in the conventional recording system with a timer function. The video recording time for the one-touch recording function can be easily and quickly set by changing only a part.

  In FIG. 4, the control unit 9 waits while monitoring the operation of the REC key 13a of the remote control transmitter 13 based on the input signal from the remote control receiving unit 14 (step S21), and the REC key 13a is operated. When the determination is made, control is performed to start a normal recording operation (step S22).

  Subsequently, after starting the above-described normal recording operation, the control unit 9 determines whether or not the REC key 13a is operated (step S23) and determines whether or not the stop key of the remote control transmitter 13 is operated (step S23). S24) is sequentially performed, and when it is determined that the REC key 13a has been operated prior to the operation of the stop key, the mode of the one-touch recording function is set and the timer circuit unit 18 is operated for a predetermined time, for example, 10 seconds. Is monitored based on the time measured by the timer circuit unit 18 to monitor whether or not a predetermined time has elapsed (step S25), and until the predetermined time elapses, the cursor of the remote control transmitter 13 is monitored. It is determined whether or not the down key 13c has been operated (step S26).

  When the controller 9 determines that the predetermined time has passed without the cursor down key 13c being operated since the one-touch recording function mode is set based on the operation of the REC key 13a (step S25), The recording time of 30 minutes is set, and the remaining recording time of 30 minutes is temporarily stored in the memory 17 and registered (step S27). On the other hand, the cursor down key 13c is operated before the predetermined time elapses. When it is determined (step S26), the maximum recording time of 8 hours is set, and the remaining recording time of 8 hours is temporarily stored in the memory 17 and registered (step S28). Immediately after the initial recording time is set, the timer circuit unit 18 is reset once, and then the timing operation for the set recording time is started.

  Next, the control unit 9 determines whether or not the recording time initially set in the memory 17 has elapsed based on the time measured by the timer circuit unit 18 (step S29), and determines until the recording time has elapsed. In the meantime, it is determined whether or not the REC key 12a has been operated (step S30). Then, when it is determined that the REC key 13a has been operated before the set recording time has elapsed (step S30), the control unit 9 determines whether a predetermined time, for example, 10 seconds has elapsed based on the time measured by the timer circuit unit 18 Whether or not the cursor down key 13c of the remote control transmitter 13 has been operated before the predetermined time elapses is monitored (step S32).

  In the determination process, when it is determined that the predetermined time of 10 seconds has passed without the cursor down key 13c being operated (step S31), a new recording time set in the memory 17 is added to 30 minutes. The recording time is calculated, and the calculated recording time is updated and registered in place of the recording time being registered in the memory 17 (step S33).

  On the other hand, when it is determined that the cursor down key 13c has been operated before the predetermined time of 10 seconds has elapsed (step S32), a new recording time is calculated by subtracting 30 minutes from the recording time set and registered in the memory 17. Then, the calculated recording time is updated and registered in place of the recording time being registered in the memory 17 (step S34).

  That is, also in this embodiment, the recording time can be set by two kinds of setting cycles, that is, the recording time up setting cycle UC and the recording time down setting cycle DC which are substantially the same as described with reference to FIG. The recording time up setting cycle UC sequentially calculates a new recording time obtained by adding 30 to the set recording time every time the REC key 13a is operated after setting the mode of the one-touch recording function. And register for update. The recording time down setting cycle DC is set recording every time the REC key 13a and the cursor down key 13c are operated continuously within a predetermined time of 10 seconds after the one-touch recording operation mode is set. A new recording time obtained by subtracting 30 from the time is sequentially calculated and registered for update.

  Since the remote control transmitter 13 transmits the command signal by the key operation to the remote control reception unit 14 by the infrared signal, the remote control transmitter 13 cannot transmit the signal by the simultaneous operation of two kinds of keys unlike the key input unit 12. In this embodiment, the recording time is set based on the recording time up setting cycle UC by repeating the operation of the REC key 13a, and the REC key 13a and the cursor down key 13c are continuously within a predetermined time of 10 seconds. The recording time is set based on the recording time down setting cycle DC by repeating the operation.

  However, as in the first embodiment, the timer circuit unit 18 is not reset regardless of whether or not the set recording time has been updated. Continue as it is. Therefore, the control unit 9 always calculates the remaining recording time by subtracting the time measured by the timer circuit unit 18 from the recording time newly updated and registered in the memory 17, and determines whether or not the remaining recording time becomes zero. That is, it is determined whether or not the set recording time has passed (step S29), and when it is determined that the set recording time has passed, the interface is prohibited so that input of video data and audio data to the MPEG encoder 20 is prohibited. While controlling the unit 19, the driving of the MPEG encoder 20, the recording signal processing unit 21 and the recording / reproducing mechanism 22 is stopped, and the recording operation is ended (step S35).

  Note that, similarly to the first embodiment, the control unit 9 temporarily stores the recording time in the memory 17 at the same time as the recording time initial setting registration and update registration as described above. The recording time is controlled to be displayed on the display 4 via the display control circuit 23 shown in FIG. Thereby, the user can visually recognize the recording time set by his / her own operation on the display 4, and can reliably set the desired recording time.

  On the other hand, after the normal recording operation is started by the user pressing the REC key 13a, if the REC key 13a is not operated, the normal recording operation is continued and the control unit 9 presses the stop key. When it is determined that it has been operated (step S24), the recording operation is terminated (step S35).

  Therefore, the recording system with a timer function of this embodiment also has two recording time setting cycles UC and DC that are almost the same as those of the first embodiment. In comparison, the desired recording time can be quickly set by a remarkably easy operation, and the existing cursor down key 13c of the remote control transmitter 13 is also used for setting the recording time. Since the above function can be obtained only by changing a part of the control program executed by the control unit 9, there is no cost increase, and the recording time down setting cycle DC and the recording time setting based thereon are set. Due to the concept of “down” common to both the cursor down key 13c, which is also used for the operation, the user can definitely remember the key 13c to be operated. There is an advantage that it is.

  In addition to the above-described effects, in this embodiment, the recording time setting operation can be performed using the remote control transmitter 14, so that the user can perform key input provided on the main body of the DVD recorder. As compared with the case where the unit 12 is operated, there is an advantage that the recording time setting operation can be performed more easily.

                                                                    FIG. 5 is a flowchart showing control processing for setting the recording time in the one-touch recording operation mode in the recording system with a timer function according to the third embodiment of the present invention. In this embodiment, as in the second embodiment, the recording time is set by manual operation of the remote control transmitter 13 provided in the DVD recorder in the recording system of FIG. In this embodiment as well, as in the first and second embodiments, the existing configuration generally included in the conventional recording system with a timer function is stored in the ROM 10 as it is. The recording time setting operation in the one-touch recording function can be easily and quickly performed by changing only a part of the control program.

  In FIG. 5, the control unit 9 waits while monitoring the operation of the REC key 13a of the remote control transmitter 13 based on the input signal from the remote control receiving unit 14 (step S41), and the REC key 13a is operated. When the determination is made, control is performed to set the normal recording operation mode and start the recording operation (step S42).

  Subsequently, after starting the above-described normal recording operation, the control unit 9 determines whether or not the REC key 13a is operated (step S43) and whether or not the stop key of the remote control transmitter 13 is operated (step S43). S44) are sequentially performed, and when it is determined that the REC key 13a has been operated prior to the operation of the stop key, the mode of the one-touch recording function is set (step S45), and then the remote control is performed based on the input signal from the remote control receiver 14 The determination whether the cursor up key 13b of the transmitter 13 has been operated (step S46) and the determination whether the cursor down key 13c has been operated (step S47) are repeated. That is, after setting the mode of the one-touch recording function, the control unit 9 waits while monitoring one of the cursor up key 13b and the cursor down key 13c.

  When determining that the cursor up key 13b has been operated (step S46), the control unit 9 sets the minimum recording time of 30 minutes, and temporarily stores the remaining 30 minutes of recording time in the memory 17 for registration. On the other hand, when it is determined that the cursor down key 13c has been operated (step S47), the maximum recording time of 8 hours is set, and the remaining recording time of 8 hours is temporarily stored in the memory 17. Then, when any recording time is set, the timer circuit unit 18 is driven from the registered time to start the recording time counting operation.

  As described above, the control unit 9 executes a partially changed control program, and either the cursor up key 13b or the cursor down key 13c is operated under the condition that the mode of the one-touch recording function is set. Only in some cases, the cursor up key 13b and the cursor down key 13c are handled as keys for setting a recording time different from the original function, and control processing is performed. Therefore, when the cursor up key 13b or the cursor down key 13c is operated when the one-touch recording operation mode is not set, that is, when the menu is displayed on the display 4, the control unit 9 displays the display 4 as in the conventional case. The control processing is performed so that the cursor being displayed is moved up or down.

  Next, the control unit 9 determines whether or not the recording time that is initially set in the memory 17 has elapsed based on the time measured by the timer circuit unit 18 (step S50), and determines until the recording time has elapsed. In the meantime, the determination as to whether or not the cursor up key 13b has been operated (step S51) and the determination as to whether or not the cursor down key 13c has been operated (step S52) are repeated. When the controller 9 determines that the cursor up key 13b has been operated before the set recording time elapses (step S51), the control unit 9 adds a new recording time that is set and registered in the memory 17 to 30 minutes. When the recording time is calculated and the calculated recording time is updated and registered in place of the recording time being registered in the memory 17 (step S53), on the other hand, it is determined that the cursor down key 13c has been operated (step S52). Then, a new recording time is calculated by subtracting 30 minutes from the recording time set and registered in the memory 17, and the calculated recording time is updated and registered in place of the recording time being registered in the memory 17 (step S54). ).

  That is, also in this embodiment, the recording time can be set by two kinds of setting cycles, that is, the recording time up setting cycle UC and the recording time down setting cycle DC which are substantially the same as described with reference to FIG. The recording time up setting cycle UC sequentially calculates a new recording time obtained by adding 30 minutes to the set recording time every time the cursor up key 13b is operated after setting the one-touch recording operation mode. And register for update. The recording time down setting cycle DC sequentially calculates a new recording time obtained by subtracting 30 minutes from the set recording time every time the cursor down key 13c is operated after setting the one-touch recording operation mode. And register for update.

  However, as in the first and second embodiments, the timer circuit unit 18 is not reset regardless of whether or not the set recording time is updated, and starts when the recording time is initialized. Continue the timekeeping operation. Therefore, the control unit 9 always calculates the remaining recording time by subtracting the time measured by the timer circuit unit 18 from the recording time newly updated and registered in the memory 17, and determines whether or not the remaining recording time becomes zero. That is, it is determined whether or not the set recording time has passed (step S50), and when it is determined that the set recording time has passed, the recording operation is ended (step S55).

  Note that, similarly to the first and second embodiments, the control unit 9 temporarily stores the recording time in the memory 17 in both cases of the above-described recording time initial setting registration and update registration. At the same time, the stored recording time is controlled to be displayed on the display 4 each time via the display control circuit 23 shown in FIG. Thereby, the user can visually recognize the recording time set by his / her own operation on the display 4, and can reliably set the desired recording time.

  On the other hand, if both the REC key 13a and the stop key are not operated after the normal recording operation mode is set by the user operating the REC key 13a and the normal recording operation is started, normal recording is performed. The operation is continued, and when the controller 9 determines that the stop key is pressed (step S44), the recording operation is terminated (step S55).

  Therefore, the recording system with a timer function of this embodiment also has two recording time setting cycles UC and DC that are substantially the same as those of the first and second embodiments, so that the conventional recording time is Compared to the setting of the recording time, the desired recording time can be set quickly with a much easier operation, and the cost is not increased. Further, as in the second embodiment, the recording time is set. Since the operation can be performed using the remote control transmitter 14, the user can perform the recording time setting operation more easily than when operating the key input unit 12 provided in the apparatus body of the DVD recorder. There is an effect that can be done.

  In addition to the effects as described above, in this embodiment, the setting of the recording time based on the recording time up setting cycle UC or the recording time down setting cycle DC in the mode of the one-touch recording function is set by the cursor up key 13b or the cursor down. Since only one of the keys 13c can be operated, the recording time can be set based on the recording time down setting cycle DC by operating both the REC key 13a and the cursor down key 13c as in the second embodiment. Compared with the case where it is performed, the operation becomes easier. Furthermore, in this embodiment, both the recording time up setting cycle UC and the recording time down setting cycle DC and the cursor up key 13b and the cursor down key 13c that are also used for the recording time setting operation based on the recording time up setting cycle UC The common concept of “down” and “down” has an advantage that the user can definitely remember the keys 13b and 13c to be operated.
