Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hard disk recorder, and more particularly, to a hard disk recorder capable of storing a program being received, displaying the stored program, and reproducing a digital video disk (DVD).
[0002]
[Prior art]
As a hard disk recorder, there is a TV program viewing apparatus described in JP-A-2002-44542. Such a hard disk recorder has been put into practical use as large-capacity hard disks can be manufactured at low cost.
[0003]
Whereas a conventional video tape recorder (VTR) cannot reproduce a recorded program until after the recording is finished, a hard disk recorder stores a program being received on a hard disk and performs a storage process. It has a time-shift playback function that displays the stored program from any location within the stored range and pauses the program display or changes the display speed during program viewing by the user's operation. I have. In addition, such hard disk recorders having a DVD playback function added thereto are also on the market.
[0004]

JP-A-2002-44542 [0005]
[Problems to be solved by the invention]
Compared with analog devices such as conventional video tape recorders, digital devices such as hard disk recorders require a large number of integrated circuits (ICs) that require control in order to realize many functions such as DVD playback functions. ).
[0006]
Further, since a complicated control is required, the configuration is not constituted by a hardware circuit but is constituted by software using a control IC such as a microcomputer. For this reason, the time required to control the internal IC is about tens of times longer than that of the conventional analog device.
[0007]
FIG. 4 shows a time sequence of power-on of a device in which a DVD function is mounted on a conventional hard disk recorder. When the power of the hard disk recorder is turned on, the DVD disk is checked after a certain period of time until the rotations of the motors of the HDD and the DVD are stabilized, and the operation of the HDD is stopped until the check of the DVD disk is completed. Subsequently, it is confirmed whether the DVD operates normally. The time required so far is, for example, 8 seconds. After confirming the normal operation of the DVD, the HDD is rotated again, and when the rotation is stabilized, it is confirmed whether or not the HDD operates normally. It takes, for example, 13 seconds after the power is turned on until the checking operation is completed.
[0008]
When the DVD and HDD are turned on simultaneously, a maximum current of 50 mA flows instantaneously. For this reason, not only the power consumption becomes large, but also a component having a high withstand voltage such as a capacitor used in an internal circuit needs to be used, and there is a problem that the cost is increased.
[0009]
Therefore, a main object of the present invention is to provide a hard disk recorder having a DVD reproducing function, capable of reducing power consumption at power-on, and capable of shortening a startup time.
[0010]
[Means for Solving the Problems]
The present invention accumulates a program being received on a hard disk, displays the program from an arbitrary position within a range in which the accumulated program is accumulated even during accumulation processing, and displays a program during program viewing by a user operation. A hard disk recorder having a time-shift playback function for temporarily stopping or changing a display speed, comprising: a DVD playback means capable of playing back a digital video disc; Immediately after the rotation of the disk motor of the DVD reproducing means is stabilized, the power of the hard disk is turned on to confirm the normal operation of the hard disk, and the power control means for confirming the operation of the DVD reproducing means. It is characterized by having.
[0011]
Another invention is a hard disk recorder that stores a program being received on a hard disk, displays the stored program, and has a DVD playback unit that plays a digital video disk. The digital video disk is detected by turning on the power first, and then, immediately after the rotation of the disk motor of the DVD reproducing means is stabilized, the power of the hard disk is turned on to check the normal operation of the hard disk, and the DVD reproducing means is checked. Power supply control means for confirming the operation of (1).
[0012]
As a result, the time from when the power is turned on to when the hard disk recorder can be used can be shortened, and the power-on timing of the DVD reproducing means and the hard disk can be changed, so that power consumption at the time of startup can be reduced.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a block diagram of a hard disk recorder according to an embodiment of the present invention. In FIG. 1, an externally input video signal is converted into a digital signal by an A / D converter 1 and provided to a compression processing unit 4. A video signal from an antenna is received by a tuner 2, and the video signal is received by an A / D converter 3. The signal is converted into a digital signal and supplied to the compression processing unit 4. The compression processing unit 4 performs a compression process to reduce the amount of information of the input video signal, and accumulates it on a hard disk (HDD) 6. The storage unit 5 is configured by a semiconductor memory or the like, and stores information on programs stored in the HDD 6.
[0014]
When the video signal stored in the HDD 6 is read, information related to the video signal is also read from the storage unit 5 and given to the decompression processing unit 7 to perform decompression processing on the video signal of the original program. Then, the video signal is converted into an analog signal by the D / A converter 8 and output to the outside. It should be noted that the hard disk recorder is also equipped with a DVD player 9, and a video signal is also output from the DVD player 9.
[0015]
The control unit 10 as a power control unit controls the compression processing unit 4, the HDD 6, the decompression processing unit 7, and the DVD player 9, and performs the power-on operation of the HDD 6 and the DVD player 9 in the embodiment of the present invention. In addition, the control unit 10 compresses the program being received by the compression processing unit 4 and accumulates the program in the HDD 6. Even during the accumulation process, the control unit 10 reads out the accumulated program from an arbitrary position within the accumulation range. The decompression processing unit 7 performs decompression processing and displays the data, and executes a time-shift reproduction function for temporarily stopping program display and changing the display speed during program viewing by a user operation.
[0016]
FIG. 2 is a flowchart for explaining the power-on operation of the hard disk recorder in one embodiment of the present invention, and FIG. 3 is a time sequence diagram.
[0017]
The flowchart shown in FIG. 2 shows a startup process after the power is turned on. When the power of the hard disk recorder shown in FIG. 1 is turned on, in step SP (abbreviated as SP in the figure) 1, the control unit 10 turns on the power of the DVD player 9 and detects a DVD disk. In step SP2, it is determined whether or not the rotation of the disk motor of the DVD player 9 is stabilized. If not, the process waits until the rotation is stabilized.
[0018]
When the rotation of the disk motor is stabilized, the power of the HDD 6 is turned on in step SP3. In step SP4, the process waits until the HDD 6 operates stably. At the same time, in step SP5, it is determined whether or not the DVD player 9 operates normally. If it is determined that the DVD player 9 operates normally, the boot process is terminated.
[0019]
Therefore, according to this embodiment, as shown in FIG. 3, when the power is first turned on to the DVD player 9, a current of, for example, 30 mA flows, and after the rotation of the DVD is stabilized, the power to the HDD 6 is turned on. Since a current of 20 mA flows, a current of 50 mA can be suppressed from flowing at the time of startup as shown in FIG. 4, and power consumption can be reduced.
[0020]
In addition, after the power is turned on to the HDD 6, the time from power-on to start-up is reduced to, for example, 8 seconds by checking the DVD disk and confirming the normal operation and confirming the rotation stability and the normal operation of the HDD 6 in parallel. be able to.
[0021]
The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
[0022]
【The invention's effect】
As described above, according to the present invention, when the power is turned on, the power of the DVD reproducing means is first turned on to detect the DVD disk, and then the power of the hard disk is turned on immediately after the rotation of the DVD disk motor is stabilized. Then, the normal operation of the hard disk is checked and the operation of the DVD reproducing means is checked, so that the time from when the power is turned on to when the hard disk recorder can be used can be shortened. In addition, the power-on timing of the DVD and the hard disk can be changed, and the power consumption at the time of startup can be reduced, so that the cost can be reduced in designing the power supply circuit.
