Description
[technical field]
The present invention relates to a kind of circuit and method that realizes TV functions, relate in particular to a kind of circuit and method that realizes the television set intelligently sleep mode function.
[background technology]
The modern society rhythm of life is accelerated, work strain in addition, and people regular meeting when watching TV night so not only wastes electric energy because tired fall asleep forgotten closing television, minimizing TV useful life, and influence other people rest.
See also Fig. 1, be United States Patent (USP) the 5th, 894, a kind of method flow schematic diagram of realizing the TV sleep mode function that is disclosed for No. 331, this method is characterized in that: the user sets in advance the sleep pattern time, and TV entered sleep pattern and show remaining time (as: 60 minutes) on screen in this time.After this TV will gradually reduce this remaining time, and show (as: 50 minutes, 40 minutes according to the predetermined time interval (as: 10 minutes) on screen ... 10 minutes).When reaching zero remaining time, system detects whether there is the button input response that comes from the user, does not think that then the user is sleeping if having, automatically closing television.
Said method is realized the TV sleep mode function by regularly closing, its weak point mainly is: during TV is carried out sleep mode function, the user need regularly pay close attention to video screen shown sleep pattern remaining time, but the user is under fatigue state, often be difficult to focus one's attention on and have no time to pay close attention to screen shown sleep pattern remaining time, thereby cause TV under no alert status, to be closed suddenly.
[summary of the invention]
Technical problem to be solved by this invention is to provide a kind of circuit and method that realizes television set intelligently type sleep mode function, it can not realize automatic closing television under the user has the situation of button input after the user is provided with sleep pattern, can realize progressively reducing stage by stage of volume and brightness simultaneously in a period of time before the closing television automatically.
The technical solution adopted in the present invention is: a kind of circuit of realizing television set intelligently type sleep mode function is provided, and this circuit comprises: a control chip, in order to the output of control television audio and vision signal; One audio frequency amplifier, the audio signal strength of importing in order to reduce.Wherein control chip further comprises a digital signal processor, and a timer that links to each other with digital signal processor respectively, a PWM (Pulse Width Modulation, pulse width modulation) output port, a LVDS (Low-voltage differential signaling, low-voltage differential signal) output port.Wherein digital signal processor further comprises a micro-control unit, a RAM and the EEPROM in order to storage user setting message in order to temporary data.Audio frequency amplifier links to each other with the PWM output port.Digital signal processor to realize sound control, is controlled display unit to realize brilliance control by the LVDS output port by PWM output port control audio amplifier.
The present invention provides a kind of method that realizes television set intelligently type sleep mode function in addition, and this method comprises: the user can freely open or the sleep mode function of closing television.TV is carried out normal running when not being in sleep pattern.TV is provided with an initial condition and is picked up counting by timer when entering sleep pattern, timer time arrives at the predetermined sleep pattern time after a period of time, if system does not detect the user key-press input during this period, then automatically television sound volume and brightness are reduced; After this arrive at another predetermined sleep pattern time through timer time after a while again,, then automatically television sound volume and brightness are reduced once more if system does not detect the user key-press input during this period.After so progressively reducing stage by stage, if do not detect user key-press input, the automatic closing television of system yet through volume and brightness for several times.
During above-mentioned no matter when, if system judges then whether it is power button when detecting the input units such as button of user on infrared remote controller or casing and importing a button, and the input button is non-to be power button, then automatically reply the sleep pattern initial condition, timer restarts timing; If detecting the user, to import button be then closing television of power button.
Utilize circuit of the present invention and method, TV sends early warning and reminds the user before closing automatically, and can directly not close suddenly.So do not influencing the useful life that effectively to save electric energy under the situation that other people have a rest and prolong TV.

Fig. 2 is the TV structure schematic diagram that comprises intelligent sleeping mode function circuit of the present invention.
Fig. 3 is the method flow schematic diagram that the present invention realizes television set intelligently type sleep mode function.
[embodiment]
Seeing also Fig. 2, is the TV structure schematic diagram that comprises intelligent sleeping mode function circuit of the present invention.This intelligent sleeping mode function circuit comprises: a control chip 10, in order to the output of control television audio and vision signal; One audio frequency amplifier 20, the audio signal strength of importing in order to reduce.Wherein control chip 10 further comprises a digital signal processor 11, and a timer 12, the one PWM output ports 13, the LVDS output port 14 that link to each other with digital signal processor 11 respectively.Wherein digital signal processor 11 further comprises a micro-control unit 111, a RAM112 and the EEPROM113 in order to storage user setting message in order to temporary data.Audio frequency amplifier 20 links to each other with PWM output port 13.Digital signal processor 11 to realize sound control, is controlled display unit to realize brilliance control by LVDS output port 14 by PWM output port 13 control audio amplifiers 20.
Seeing also Fig. 3, is the method flow schematic diagram that the present invention realizes television set intelligently type sleep mode function.The user can freely open the sleep mode function of TV, and system at first judges whether to be in sleep pattern (step 100), if when not being in sleep pattern, does not then carry out sleep mode function; If be in sleep pattern, then carry out following operation:
The initial condition of sleep pattern is set, timer pick up counting (step 200); Timer time arrives at predetermined sleep pattern time T 1 after a period of time, system detects whether user key-press input (step 300) is arranged during this period, if system does not detect the user key-press input during this period, then automatically television sound volume and brightness are reduced (step 400); If system detects the user and imports a button from the input units such as button on infrared remote controller or the casing during this period, judge then whether it is power button (step 310), the input button is non-to be power button, then automatically reply the sleep pattern initial condition, timer resets and restarts timing (step 200); The input button is a then closing television (step 600) of power button.
Television sound volume and brightness reduce after (step 400) again through after a while, timer time arrives at predetermined sleep pattern time T 2, system detects whether user key-press input (step 500) is arranged during this period, if system does not detect user key-press input, then closing television (step 600) during this period; If system detects the user and imports a button from the input units such as button on infrared remote controller or the casing during this period, judge then whether it is power button (step 510), the input button is non-to be power button, then automatically reply the sleep pattern initial condition, timer resets and restarts timing (step 200); The input button is a then closing television (step 600) of power button.So reduce the automatic closing television of back system stage by stage through volume and brightness.
In the present embodiment, after only reducing via volume and brightness, system does not detect user key-press and imports promptly closing television automatically, but in actual the use as required, after process several volume and brightness progressively reduce stage by stage, system does not detect the just automatic closing television of meeting of user key-press input, and in actual applications, this number of steps is generally four times.
