For solving technical problem of the present utility model, the utility model discloses a kind of television set with clocking capability, comprising: be used for the TV signal that receives is carried out the control circuit unit that the demodulation sign indicating number is handled; And the display unit that is connected described control circuit unit output; Described control circuit unit comprises: the timing module that is used for carrying out work statistics service time after television set is opened; Be used to store the timing memory module of the time data that described timing module adds up; And be used to control the statistics television set timing control module of total work service time, be connected with described timing memory module with described timing module respectively; And among described timing module, described timing memory module and the integrated central processing element that is arranged in the described control circuit unit of described timing control module.

More excellent, described control circuit unit comprises: the demodulation module that is used for the TV signal that receives is carried out demodulation process; Be connected the demodulation module output, be used for doing respectively the audio decoder module and the video decode module of audio decoder and video decode processing; And system control module, connect described demodulation module, described audio decoder module, described video decode module and described timing control module simultaneously.

More excellent, described timing memory module is the built-in memory module of multiplexing described central processing element.

More excellent, described memory module is the sram memory module.

More excellent, described timing module is the built-in counter of multiplexing described central processing element.

Compared with prior art, the utlity model has following beneficial effect:

1, the utility model is by the counter in the multiplexing central processing element work of television set to be added up service time, and statistics deposited in the sram memory to the central processing element, form television set total work service time, therefore, the utility model can be noted television set total work service time clearly, can conveniently analyze and study the television set key components;

2, clocking capability of the present utility model is counter and the sram memory in the multiplexing central processing element, need not increase hardware device, and therefore, the utility model realizes having lower-cost advantage easily in addition.

Fig. 2 is the electrical block diagram of control circuit unit in the utility model.

Embodiment

Core concept of the present utility model is: the built-in counter of the central processing element of multiplexing television set (CPU), when opening television set, carry out timing at every turn, and finish timing during the closing television machine; And the control chronometric data that counter is each is stored in the sram memory of central processing element, on the basis that reaches the hardware cost that does not increase television set, obtains television set total work service time.

Please refer to shown in the figure.Television set of the present utility model comprises: be used for the TV signal that receives is carried out the control circuit unit 110 that the demodulation sign indicating number is handled; And the display unit 120 that is connected described control circuit unit 110 outputs.

Described control circuit unit 110 comprises central processing element and peripheral circuit thereof, please refer to detailed circuit structural representation shown in Figure 2.Wherein, central processing element is one of many moneys multimedia process chip that can buy on the market, such as, NXP multimedia processor PNX8536, picture quality enhanced system level chip PNX505x, etc.This enforcement is that to adopt model be the multimedia processor of PNX8536, and its internal structure and function are this area professional's common practise, at this enumeration no longer.

Described control circuit unit 110 comprises: the demodulation module 111 that is used for the TV signal that receives is carried out demodulation process; Be connected the output of described demodulation module 111, be used for doing respectively the audio decoder module 112 and the video decode module 113 of audio decoder and video decode processing; Be used for after television set is opened, carrying out the timing module 114 of work statistics service time; Be used to store the timing memory module 115 of the time data that described timing module 114 added up; Be used to control the statistics television set timing control module 116 of total work service time, be connected with described timing memory module 115 with described timing module 114 respectively; The system control module 117 that connects described demodulation module 111, described audio decoder module 112, described video decode module 113 and described timing control module 116 simultaneously.

That is to say, after the TV signal that receives is carried out demodulation process through described demodulation module 111, audio decoder is handled and the video decode processing because described audio decoder module 112 and described video decode module 113 are done respectively, and described audio decoder module 112 and described video decode module 113 reach the display unit 120 that is attached thereto with voice data and video data respectively.

And, among all integrated central processing element that is arranged in the described control circuit unit 110 of described demodulation module 111, described audio decoder module 112, described video decode module 113, described timing module 114, described timing memory module 115, described timing control module 116 and described system control module 117.

Described timing module 114 is the built-in counter of multiplexing described central processing element.When the user each when opening television set, start central processing element, counter picks up counting, and after central processing element is activated, promptly move the background work pattern, the chronometric data during from last user's closing television machine the described timing memory module 115 is that the basis adds up timing; When user's closing television machine, counter finishes timing, and described timing memory module 115 is exported and be stored to chronometric data.Treat to open next time the timing statistics that the television set hour counter continues to do accumulative total.

Certainly, the user can also check total use operating time of television set by the timing menu of television set, that is to say the chronometric data that reads storage from described timing memory module 115, timing menu by television set is shown to the user, understands television set total work service time to become the user.If television set breaks down when maybe needing to safeguard with upgrading, the attendant can also read the chronometric data of storage in the described timing memory module 115 by other fetch equipments, so that convenient the television set key components is analyzed, studied and improves.

Described timing memory module 115 is the built-in memory module of multiplexing described central processing element, and this memory module is the sram memory module.Thus, can not take system's external resource of television set, and timing statistics is at running background, do not take the internal memory and the running time of television set built-in system.

In sum, the utility model can be noted television set total work service time clearly, can conveniently analyze and study the television set key components, can make things convenient for after-sales service and the improvement of exploitation in the future more specifically.And can allow the consumer know the operating time that machine is total, need change or maintain, especially to LCD TV, the useful life that cans be compared to TV was above 10000 hours, because backlight is aging, can suitably remind the consumer manually to heighten brightness backlight, can increase the image quality and the visual experience of image like this.Clocking capability of the present utility model in addition is counter and the sram memory in the multiplexing central processing element, need not increase hardware device, and therefore, the utility model realizes having lower-cost advantage easily in addition.
