Picture signal handling part 21 is selected required channel and the receiving broadcast signal of user, the broadcast singal that demodulation in selected frequency channel (modulation) receives, the broadcast singal (transmission data flow) of decoding demodulation, it can be regenerated and store, and the view data in the data of decoding is counted processing, it be may be displayed in the display part (50).
The image that display part 22 is handled above-mentioned picture signal handling part 21 is presented in the picture.
Control part 23 is made up of general central processing unit (CPU or MPU), control above-mentioned picture signal handling part 21 and the 1st, 2 storage parts 25,26, the image that stored broadcast image and user record in each storage part 25,26 etc., and above-mentioned image is presented in display part 22 pictures after above-mentioned picture signal handling part 21 is handled.
The the 1st and the 2nd storage part 25,26 is by hard disk drive (HDD), and memory card and other set of storage devices become, and the image of recording according to the above-mentioned broadcast image of the control store of above-mentioned control part 23 and user etc.
Under this state, when above-mentioned control part 23 is made video recording image at above-mentioned the 1st storage part 25,, then control it and provide power supply to above-mentioned the 2nd storage part 26 if problems such as the hardware power supply is bad take place, above-mentioned image is continued to be recorded in above-mentioned the 2nd storage part 26.
For this reason, image recording device for personal use also should comprise: according to the control of above-mentioned control part 23, with any one optionally is connected and provides the switch portion (FET switch element) 24 of working power in above-mentioned the 1st storage part 25 or above-mentioned the 2nd storage part 26.
Again, when above-mentioned control part 23 is recorded image at above-mentioned the 1st storage part 25,, then control above-mentioned switch portion 24, provide power supply, continue to continue program recording in above-mentioned the 2nd storage part 26 to above-mentioned the 2nd storage part 26 if its storage appearance capacity exceeds.And above-mentioned the 2nd storage part 26 can be made up of a plurality of hard disk drives.
Fig. 3 is the control method flow chart of image recording device for personal use among the present invention.
As shown in the figure, comprise among the present invention among the present invention: the power supply unit 20 that working power is provided to the 1st and the 2nd storage part 25,26; The broadcast singal of demodulate reception in the selected channel frequency, the broadcast singal of decoding demodulation can be regenerated and store it, and decoded image signal is counted the picture signal handling part 21 of handling and exporting; The image that above-mentioned picture signal handling part 21 is handled is presented at the control method of the image recording device for personal use of the display part 22 in the picture, comprises: the image that broadcast image that above-mentioned picture signal handling part 21 is handled and user record etc. is stored in stage S101, the S103 in above-mentioned the 1st storage part 25; When above-mentioned the 1st storage part 25 is made video recording image, if problem S104 such as the hardware power supply is bad take place, then provide power supply to above-mentioned the 2nd storage part 26, continue in above-mentioned the 2nd storage part 26, to record stage S105, the S107 of above-mentioned image.Again, when in above-mentioned the 1st storage part 25, recording image,, then provide power supply, continue in above-mentioned the 2nd storage part 26, to record above-mentioned image to above-mentioned the 2nd storage part 26 if its memory capacity exceeds.
To having said structure, effect of the present invention is described in detail as follows:
At first, as shown in the figure, power supply unit 20 receives AC power (AC) commonly used and is converted into DC power supply (DC), and provides it to the each several part of device.
Picture signal handling part 21 is selected required channel and the receiving broadcast signal of user, the broadcast singal that demodulation in selected frequency channel (modulation) receives, the broadcast singal (transmission data flow) of decoding demodulation, it can be regenerated and store, and the view data in the data of decoding is counted processing, it be may be displayed in the display part 50.
The image that display part 22 is handled above-mentioned picture signal handling part 21 is presented in the picture.
As mentioned above, under the state of carrying out general image processing work, the user begins the PVR recording function S101 of taped broadcast data flow.
Therefore, control part 23 will be by the broadcasting of above-mentioned picture signal handling part 21 outputs, or the image of from external instrument the user being recorded is stored in the 1st storage part 25.
At this moment, above-mentioned switch portion 24 links to each other with the 1st storage part 25, and above-mentioned power supply unit 20 offers above-mentioned the 1st storage part 25 with the 1st power supply, drives above-mentioned the 1st storage part 25, sees Fig. 3 S102-S103 step.
Under this state, when recording image, if problem such as the hardware power supply of generating means is bad, the work of then above-mentioned the 1st storage part 25 is terminated and can't program recording.
At this moment, above-mentioned control part 23 among the present invention as mentioned above, when above-mentioned the 1st storage part 25 was recorded image, problem S104 then provided power supply to above-mentioned the 2nd storage part 26 in time if the hardware power supply of generating means is bad etc., continues to record above-mentioned image in above-mentioned the 2nd storage part 26.
That is, according to the control of above-mentioned control part 23, switch portion 24 links to each other with the 2nd storage part 26, the 2nd power supply of above-mentioned power supply unit 20 outputs offers above-mentioned the 2nd storage part 26, drive above-mentioned the 2nd storage part 26, continue the data that above-mentioned the 1st storage part 25 of storage is recorded, see Fig. 3 S105-S107 step.
Therefore, can not lose important information when hardware is bad yet, can continue to record.
Again, when above-mentioned control part 23 is recorded image at above-mentioned the 1st storage part 25,, also control above-mentioned switch portion 24, provide power supply, continue in above-mentioned the 2nd storage part 26, to record above-mentioned image to above-mentioned the 2nd storage part 26 if its memory capacity exceeds.
At this moment, for the compound TV of general DVR, the 1st storage part (primary storage portion; HDD) the 25 and the 2nd storage part 26, that is, auxiliary storage portion (HDD, memory card, 1394 instruments etc.), its power line provides the 1st and the 2nd power supply separately by switch portion 24, data and control line walk abreast (parallel).During primary storage portion (HDD) generation problem (hardware faile), the power line of primary storage portion the 1st storage part 25 cuts off the input power supply by switch portion 24, the 2nd storage part 26 provides power supply to auxiliary storage portion, the 2nd storage part 26 (HDD, memory card, 1394 instruments etc.) continue to record by data and control line.
Moreover above-mentioned the 2nd storage part 26 can be made up of a plurality of hard disk drives, and this change can main thought according to the present invention be carried out numerous variations.
Above-mentioned enforcement does not limit the present invention in any form, and all technical schemes that form obtained of taking to be equal to replacement or equivalent transformation all drop within protection scope of the present invention.
