Abstract
The TV set comprises a MCU and a ROM used for saving the TV signal intensity. The method comprises: the program in the MCU continuously makes cycle running at backstage, and reads out the value of the register every second; according to size of the read-out value of the register, the program calls the corresponding OSD to display and decides if the read-out value of the register is the same with the value previously read-out in order to decide if the OSD needs to be refreshed.
Description
[technical field]
The present invention relates to television set, relate in particular to the OSD display packing of TV set signal intensity.
[background technology]
Along with the raising of people's living standard, of a great variety, household electrical appliance that make rapid progress have been come into the family of ordinary people.Television set can also bring a lot of knowledge to people when fully enriching people's free life.It is as you know that present mobile phone has the function of detection signal strength, and can mobile phone can be judged according to the intensity of signal accept phone.But present television set does not have the function of the intensity detection of television signal, and the user can't see TV and can think that TV has problem sometimes.In fact, TV signal is bad all is to cause a little less than the TV signal to a great extent.Therefore, be necessary that the OSD that increases signal strength detection in TV shows, can remind the signal strength signal intensity of user's television set at any time, so that in time pinpoint the problems, trouble shooting better is users' service.
[summary of the invention]
Technical problem to be solved by this invention is, a kind of inspection television set OSD display packing is provided, and has solved the present situation that existing television set can't shows signal.
The technical solution adopted in the present invention is: the OSD display packing that a kind of TV set signal intensity is provided, this television set comprises the readable register of MCU and storage TV set signal intensity, it is characterized in that the OSD display packing of described TV set signal intensity may further comprise the steps:
A.MCU reads the signal strength values of register in the colour decoding module, calls corresponding OSD according to the signal strength values of the register of reading, and shows at television screen.
More specifically, described step a also comprises
Al.MCU judges whether the signal strength values of the register of reading is the same with the value of reading last time, and whether decision will show is refreshed OSD.
More specifically, if the signal strength values of the register read is different with the value of reading last time, described MCU calls the function that OSD refreshes and shows OSD, and behind the signal stabilization, OSD shows disappearance in 10 seconds.
More specifically, if the signal strength values of the register of reading is the same with the value of reading last time, described MCU never calls OSD and shows the program that refreshes.
More specifically, described MCU and colour decoding module are by the I of master chip inside
2The C bus connects.
The present invention compared with prior art, beneficial effect is: the OSD display packing that a kind of TV set signal intensity is provided, solved the present situation that existing television set can't detection signal, can allow the user judge the intensity of oneself TV signal, if really since TV signal bad, can do the maintenance and the detection of holding wire.
[description of drawings]
Fig. 1 is SN0, the SN1 of 03 register in the UOCIII chip, the register schematic diagram of SN2.
Fig. 2 is the signal amplitude table of the different value correspondence of SN0, SN1, SN2.
Fig. 3 is the flow chart of TV set signal intensity OSD display packing of the present invention.
[embodiment]
Television set of the present invention comprises the UOCIII chip, and described UOCIII chip comprises the readable register of MCU and storage TV set signal intensity.MCU in the described UOCIII chip is by inner I
2The C bus is connected with the readable register of storage TV set signal intensity, reads the signal strength values of 03 register in the readable register of this storage TV set signal intensity.
In the readable register of the signal strength signal intensity of the storage television set of described UOCIII chip, the register that three BIT positions of D1-D3 called after SN0, SN1, SN2 are arranged, the register of described SN0, SN1, SN2 is a readable register, deposits the amplitude of the signal strength signal intensity of TV.Described MCU is by UOCIII chip internal I
2The C bus is read the signal strength values of register in the described UOCIII chip at any time, just can know the intensity of current channel signal according to the signal strength values comparison of the signal strength values of the register of reading and register before, size according to readout, just can change the amplitude of OSD shows signal intensity on video screen, the user just can judge which kind of signal strength signal intensity TV is under according to the variation of OSD.
As shown in Figure 2, television set OSD display packing of the present invention may further comprise the steps:
Step 1: after the television boot-strap, the UOCIII chip power.
Tape program circulates on the backstage in the step 2:MCU, reads the signal strength values of SN0, SN1 in the UOCIII chip, SN2 register in per 1 second.
Step 3: described MCU reads the size of the signal strength values of SN0, SN1, SN2 register, and whether the signal strength values of judging SN0, the SN1 read, SN2 register is the same with the value of last time.If the value of SN0, SN1, SN2 and last sub-value are different, described MCU calls the function that OSD refreshes and refreshes OSD, and OSD is shown by the signal strength values of the register of new SN0, SN1, SN2, and during signal stabilization, OSD shows disappearance in 10 seconds; If the signal strength values of SN0, SN1, SN2 register is the same with the value of last time, just never calls OSD and show SN0, the SN1 that refreshes, the value of SN2.
During television boot-strap, repeat above-mentioned steps always.The user in time pinpoints the problems according to the intensity of the TV signal that shows, trouble shooting can be done the maintenance and the detection of holding wire.
Claims (5)
1, a kind of OSD display packing of TV set signal intensity, this television set comprise the readable register of MCU and storage TV set signal intensity, it is characterized in that the OSD display packing of described TV set signal intensity may further comprise the steps:
A.MCU reads the signal strength values of color register, calls corresponding OSD according to the signal strength values of the register of reading, and shows at television screen.
2, the OSD display packing of TV set signal intensity as claimed in claim 1 is characterized in that, described step a also comprises
A1.MCU judges whether the signal strength values of the register of reading is the same with the value of reading last time, and whether decision will show is refreshed OSD.
3, the OSD display packing of TV set signal intensity as claimed in claim 2, it is characterized in that if the signal strength values of the register read is different with the value of reading last time, described MCU calls the function demonstration OSD that OSD refreshes, behind the signal stabilization, OSD shows 10 seconds and disappears.
