Description

  The present invention relates to a recording / reproducing apparatus capable of recording and reproducing a video signal.

In a television receiver, power-on / off data is learned and stored for at least one week, and based on this data, all power-off mode and standby mode (modes in which electronic circuits that start up slowly are energized even when the power is off) There is known one that controls (Patent Document 1).
JP, 7-212678, A By this, it is possible to realize a quick start and reduce power consumption by adjusting to the user's lifestyle as a standby mode when the usage frequency is high and as an all power off mode when the usage frequency is low. There is. However, this device has a problem that when the power-off mode is continued for one week, there is only power-off data for the next week, so the power-off mode is entered and a period in which the quick start cannot be used occurs. there were.

  The conventional apparatus learns and records the power on / off data for one week, and controls the all power off mode and the standby mode based on this data. For this reason, although the mode is switched according to the frequency of use, for example, the user turns on the recording / reproducing device after returning to his / her home with the recording / reproducing device turned off for a week or the like. When the power is turned off, the all-power-off mode is selected from the learning data for one week, so even if the user turns on the power again, the recording / playback device starts from the all-power-off mode instead of the standby mode. Since it started up, it took longer to start up than in standby mode.

That is, the conventional apparatus has a problem that it is not easy to use because the recording / reproducing apparatus is not started from the initially set mode.
It is an object of the present invention to provide a recording / reproducing apparatus that is convenient for the user when the recording / reproducing apparatus is started from an initially set mode.

In order to achieve the above object, a recording / reproducing apparatus of the present invention includes a power source for supplying power to the recording / reproducing apparatus, and energizing the power from the power source to a part of the recording / reproducing apparatus. A first switch to be performed; a second switch for energizing a portion of the recording / reproducing apparatus not energized by the first switch; and a control means for controlling the first switch and the second switch. And the control means energizes the recording / reproducing apparatus via the first switch to place the recording / reproducing apparatus in a standby state, and the recording / reproducing apparatus. , without any energization of said first switch and said second switch, and a second mode in which the recording and reproducing apparatus in the standby state, was energized entire front type recording and reproducing apparatus And the standby state If that, one of the first or second mode, characterized by being configured so as to shift the state to the preset mode.

  And, when energizing the entire recording / reproducing apparatus, when entering the standby state, the mode that is always set to the state before the period of the first mode and the second mode becomes variable In other words, since the mode is returned to the initial setting mode, when the entire recording / reproducing apparatus is energized next time, the mode is started from the initial setting mode, which is convenient for the user.

In addition, when the first mode and the second mode continue for a predetermined period, the mode continued for the predetermined period is changed to a different mode.
Further, when the first mode continues for a predetermined period, the mode is shifted to the second mode.
In the first mode (high-speed standby mode), for example, when the user goes out for a long time such as travel and does not operate the recording / reproducing apparatus, the second mode (normal standby mode) with less power consumption is used. By automatically switching, power consumption can be suppressed.

  Further, when the entire recording / reproducing apparatus is energized at a predetermined time in the standby state in the second mode, the mode is shifted to the first mode when a time before the predetermined period of the predetermined time comes. It is characterized by making it.

  When the time is close to the designated time, the second mode (normal standby mode) is changed to the first mode (high-speed standby mode), and then the entire recording / reproducing apparatus is energized, so the startup time is short.

In addition, when the remote controller signal different from the remote controller signal of the recording / reproducing apparatus is received by the recording / reproducing apparatus, the measurement for a predetermined period is initialized.
Since the mode is changed in consideration of the operation status of other devices attached to the recording / reproducing device, the convenience of the user is good.

  According to the present invention, it is possible to provide a recording / reproducing apparatus that is convenient for the user by starting the recording / reproducing apparatus from the initially set mode.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a block diagram of a recording / reproducing apparatus described in this embodiment. The recording / reproducing apparatus 100 can handle both the optical disc (DVD-R / RW / RAM, HD DVD recordable disc) and the HDD recording device 4 as a recording medium. As the recording device 4, for example, It is also possible to use a semiconductor memory or the like.

  The recording / reproducing apparatus 100 includes a DVD / HDD recording device 4, a main CPU 1 that controls recording / reproducing of the recording / reproducing apparatus 100, and an output unit 2 that reproduces the source recorded in the recording device 4 and outputs the input source. In order to record in the recording device 4, the input unit 3 that is analog or digital input from the outside, the energization management of each block, reception of the remote control signal, installed on the front panel (not shown) of the recording / reproducing apparatus 100 The sub CPU 5 reads the power key, and the power source 9 supplies power to the recording / reproducing apparatus 100.

  When the recording / reproducing apparatus 100 is connected to a power outlet, the sub CPU 5 is energized, and the recording / reproducing apparatus 100 enters a standby state, and can accept signals from a power key (not shown) and a remote controller. When the user instructs to turn on the recording / reproducing apparatus 100 with a power key or a remote controller, the sub CPU 5 energizes the entire recording / reproducing apparatus 100 to enable recording and reproduction. The sub CPU 5 is provided with a main CPU 1, an activation signal K 16 that controls the switch 20 that energizes the output unit 2, and an activation signal K 27 that controls the switch 10 that energizes the recording device 4 and the input unit 3.

In the recording / reproducing apparatus 100 described in the present embodiment, two standby states are prepared: a standby state in the normal mode and a standby state in the standby mode for fast startup.
The above two modes will be described with reference to the timing chart of the power switch in the high-speed standby mode and the normal standby mode in FIG.
First, the normal standby mode corresponds to the normal standby mode of FIGS. 2 (a) and 2 (b), and the power switch of FIG. 2 (c) is in an off state. In this state, the sub CPU 5 is configured such that both the activation signal K16 and the activation signal K27 output Low, and the main CPU 1, the output unit 2, the recording device 4, and the input unit 3 are not energized. In this standby state, when the user selects the power ON (startup) with the power key or the remote control, the sub CPU 5 sets the start signal K16 and the start signal K27 to High (thereby, the switch 10 , 20 is turned ON), and the main CPU 1 and the recording device 4 are both energized. The main CPU 1 first calls a control program from a program storage ROM (not shown) to start control of each unit, and then completes preparation for recording and reproduction in the order of output signal processing, initialization of the recording device 4, and input signal processing. . If this program amount is large, the time until activation (activation time) is long. Similarly, if the number of outputs is large, the output signal processing increases and the activation time becomes long.

  The output signal processing means that the video DAC and audio DAC that convert the digital signal sent from the main CPU 1 into analog signals are reset from the main CPU 1 and initialized with the serial control line. Is to show that The initialization of the recording device 4 is to release the reset from the main CPU 1 and initialize it with the ATAPI control line so that recording transfer transmission and reproduction transfer reception can be performed. The input signal processing means that the video ADC and audio ADC made from the analog signals of the digital signals sent to the main CPU 1 are reset from the main CPU 1 and initialized with the serial control line. Indicates that a digital signal converted from is received.

  Next, the high-speed startup standby mode corresponds to the high-speed standby mode shown in FIGS. 2A and 2B, and the power switch shown in FIG. 2C is off. In this state, the sub CPU 5 outputs High for the activation signal K1 6 and Low for the activation signal K2 7, and the main CPU 1 and the output unit 2 are energized, and the input unit 3 and the recording device 4 are not energized. It is. In this standby state, when the user selects power ON (startup) with the power key or the remote control, the sub CPU 5 sets the start signal K2 7 to High and energizes the input unit 3 and the recording device 4 as well. Be started. The main CPU 1 and the output unit 2 have already been activated and can output an initial image and sound immediately. In parallel with the initial image and audio output, processing is performed in the order of initialization of the recording device and input signal processing to complete preparation for recording and reproduction. In the standby mode for high-speed activation, compared with the normal activation mode, the activation time until recording / reproduction becomes possible is shortened by the time until the control start in the main CPU 1 and the output signal processing activation time.

  When the user does not use the recording / reproducing apparatus 100 for a long time, the standby state in the high-speed standby mode consumes unnecessary power. Therefore, in this embodiment, a function for automatically changing the energization mode in the standby state according to the use state in the standby state is provided, and the power ON is always configured to start from the initially set state. .

FIG. 3 shows an operation flowchart of the recording / reproducing apparatus 100 when the high-speed standby mode is set as the initial setting as shown in FIG.
The point of FIGS. 2A and 3 is that, as shown in FIG. 2A, when the high-speed standby mode is set in the initial setting, the mode always shifts to the high-speed standby mode after the power is turned on. Thus, even if the power switch is turned off after the recording / reproducing apparatus 100 is not used for a long period of time and then the power switch is turned off, the high-speed standby mode with a short start-up time is always obtained, and the user convenience is good.

  Further, the standby mode for high-speed activation is selected, the activation signal K27 is output low, the transition is made from the activated state to the standby state, and the sub CPU 5 starts measuring time. When the measured time continues for one week or longer, the activation signal K16 is changed to Low output and the normal standby mode is entered. This is because it is estimated that the user forgets to change the setting of the standby mode when going out for a long time, and the recording / reproducing apparatus 100 shifts to the normal standby mode. In FIG. 3, T2 = 1 week in FIG. 2A is set as the predetermined time.

  In FIG. 3, first, it is checked whether or not the power of the recording / reproducing apparatus 100 is turned on (step S101). If Yes, the recording / reproducing apparatus 100 performs a recording / reproducing operation if the power is turned on (step S101). Step S102). If No in step S101, the process in subsequent step S104 is performed. Next, it is checked whether or not the recording / reproducing apparatus 100 is turned off (step S103). If No, the process of step S102 is continued. In the case of Yes, the process shifts to the initially set high-speed standby mode (corresponding to the high-speed standby mode from the power-on mode in FIG. 2A) and starts counting elapsed time. Check whether or not the power-off elapsed time has exceeded the set time (here, T2 = 1 week) (step S105). Then, it shifts to the normal standby mode (corresponding to the normal standby mode of FIG. 2A). The normal standby mode can suppress power consumption compared to the high-speed standby mode. If No, the process returns to step S101. When the normal standby mode is entered in step S106, this flowchart ends. However, if the power of the recording / reproducing apparatus 100 is separately turned on by the user, step S101 is executed using this as a trigger.

  Note that T2 = 1 week in FIG. 3 may be changed by the user. For example, when the predetermined time is set to 1 day, when the transition to the next standby state is made after the setting, if the time measurement in the sub CPU 5 is 1 day or more, the start signal K16 is changed to Low output, and normal standby is performed. Enter mode.

FIG. 4 shows an operation flowchart of the recording / reproducing apparatus 100 when the normal standby mode is set as the initial setting as shown in FIG. 2B, unlike FIG. 2A.
The point of FIG. 2B and FIG. 4 is that, as shown in FIG. 2B, when the normal standby mode is set in the initial setting, the mode always shifts to the normal standby mode after power-on. Thereby, the power consumption of the recording / reproducing apparatus 100 can be suppressed.

  In addition, when the user has a clear period of going out and knows when there is a possibility of resuming use (drama scheduled recording during the travel period), etc. Is set to normal standby mode, and before the specified time (T1) of the designated time (drama scheduled recording start time), it is possible to shift to high-speed startup standby mode to reduce power consumption during periods not used such as going out. It is.

In FIG. 4, the same operations as those in FIG. 3 are denoted by the same step numbers, description thereof is omitted, and only different portions from FIG. 3 are described.
In Step S103 of FIG. 4, if No, the process of Step S102 is continued. In the case of Yes, the normal standby mode (equivalent to the normal standby mode from the power-on mode in FIG. 2B) is shifted to the initial setting, and T1 (for example, drama reservation start time) at the specified time (for example, 1 hour ago) is checked (step S405). If Yes, in preparation for the drama reservation start, the mode shifts to a high-speed standby mode (corresponding to the high-speed standby mode in FIG. 2B). If No, the process returns to step S101. When the normal standby mode is entered in step S406, this flowchart ends. However, when the reserved recording time is reached, the recording / reproducing apparatus 100 is automatically turned on, and this is used as a trigger to execute step S101.

  In the recording / reproducing apparatus 100, when a plurality of remote control modes (for recording / reproducing apparatus, for TV, etc.) can be set, the set remote control code (recording / recording apparatus 100) can be used while waiting in the fast start standby mode. When a remote control signal (for TV) that is different from that for the playback device 100 is received, it can be assumed that the user is operating the TV near the recording / playback device 100, so the recording / playback device 100 can be operated. Therefore, even if the standby time in the startup mode for high-speed standby is determined to have elapsed for a predetermined time, it may be configured not to shift to the normal mode. . The time measurement in this case can be realized by initializing and measuring again from the time when a different remote control code is received (for example, the elapsed time is initialized in step S105 in FIG. 3).

FIG. 5 shows an operation flowchart when the high-speed standby mode is initialized by another remote control operation.
In FIG. 5, the same operations as those in FIG. 3 are denoted by the same step numbers, description thereof is omitted, and only the portions different from FIG. 3 are described.
When a remote control signal (for example, for TV) different from the remote control code for the recording / reproducing device 100 is received (Yes in step S110), the elapsed time is initialized (step S111). If No in step S110, the check in step S105 is performed.
