Abstract
The present invention relates to a turnon and turnoff control method for a dual-CPU television via an SCART interface. The method comprises the processes that a subsidiary CPU is arranged for controlling the signal detection and the arousal of a complete machine, a user respectively set a first and a second SCART ports of the complete machine via a remote controller, and the zone bits of the level detection and turnon control information of ADC1 and ADC2 are written into an EEPROM of the subsidiary CPU. In the stand-by state, if detecting the turnon signal of the SCART 1 port or the SCART 2 port, the subsidiary CPU firstly reads the arrangement of the SCART of the user and judges the corresponding zone bit, if the zone bit is 1, turn operation is executed, if the zone bit is 0, no operation is executed, and the turnon operation is executed according to the normal mode until a remote control or key turnon signal comes; when the turnoff operation is executed, a main CPU receives an SCART turnoff signal, the turnoff operation is executed according to the normal process, etc. The present invention can lower power consumption, can cause the user to directly control the turnon and the turnoff via the SCART interface and temporarily close the function, and can be widely used for televisions which adopt dual-CPU and are exported to Europe.
Description
Technical field
The invention belongs to the TV set circuit technical field, more particularly relate to the design of double CPU TV set, to realize by the controlled function of SCART interface to switching on and shutting down by the on-off control method of SCART interface.
Background technology
Along with the development of TV signal digital processing technology, the performance of television set also obtains lifting at full speed.But in general, the high-performance of television set must be brought high power consumption.In order to reduce power consumption, to raise the efficiency, many high-end television sets adopt the processing mode of two CPU controls, and host CPU is handled various signal datas, and sub-CPU only is responsible for switching on and shutting down.It can solve the contradiction that high-performance must be brought high power consumption, in the high performance while of improving television set, reduces its power consumption greatly.
Television set need be controlled switching on and shutting down by the SCART interface when the outlet European Region.The control level signal is arranged in the SCART interface, and shutting down is low level, and starting shooting is high level, and the TV main frame need detect this signal.For example set-top box links to each other with TV by the SCART interface, when the closure plane top box, and the shutdown of TV automatic stand-by; And when opening set-top box, the TV Auto Power On.But the television set of this pair of CPU control is very difficult to the detection and the processing of SCART signal, thereby is difficult to by the SCART interface switching on and shutting down be controlled.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and the on-off control method of a kind of double CPU TV set by the SCART interface is provided.It had both adopted two CPU controls, can reduce power consumption, raise the efficiency, can allow the user pass through switching manipulation again to the audio ﹠ video equipment (as DVD or set-top box etc.) that is connected with the SCART interface with television set, the directly switching on and shutting down of control television set, and can pass through certain operation setting of remote controller with this function temporary close.
In order to achieve the above object, the present invention includes and be provided with that host CPU is responsible for complete machine software systems operations, digital video signal goes functions such as interlacing processing, integral image control, main, sub-CPU is set passes through I
2C bus SCL, SDA connection carrying out communication is also passed through special circuit connection I/O mouth separately.It is further comprising the steps of:
(1) input, the system wake-up function that sub-CPU is responsible for complete machine is set;
(2) by remote controller 1 port and 2 ports of the SCART of whole set of television are carried out setting operation respectively by the user: will to the level detection start control information of analog to digital converter ADC1 and analog to digital converter ADC2 totally two flag bits write among the EEPROM of sub-CPU;
(3) under holding state, sub-CPU is if detect 1 port of SCART or the starting-up signal that 2 ports send, and the SCART that reads the user earlier is provided with, and its corresponding flag bit analog to digital converter ADC1 or analog to digital converter ADC2 are judged, if 1, the operation of then starting shooting;
(4) if 0, then ignore this SCART starting-up signal, do not carry out any operation, arrive until remote-controlled start-up signal or button starting-up signal, press normal mode again and start shooting;
When (5) shutting down, because master, sub-CPU, press the normal step shutdown again and get final product so receive the SCART off signal by host CPU in operate as normal at this moment.This time has only sub-CPU different in work with start.
Except that general conventional func, the present invention is provided with that host CPU is responsible for the software systems operation of complete machine, digital video signal goes functions such as interlacing processing, integral image control; Input/system wake-up function that sub-CPU is responsible for complete machine is set.And make main, sub two CPU pass through I
2C bus SCL, SDA connection carrying out communication is in addition by special circuit connection I/O mouth separately.By this I/O mouth, the shutdown command quilt CPU that host CPU sends receives and carries out corresponding operating, can realize operations such as timing shutdown; And under holding state, sub-CPU is provided with (existing among the EEPROM of sub-CPU) if detect starting-up signal by the SCART that reads the user, and operation judges whether to start shooting.
Specifically, when the user carries out setting operation by remote controller to SCART, host CPU is communicated by letter as the slave unit transmitting terminal with sub-CPU as the main equipment transmitting terminal, will to the level detection of analog to digital converter ADC1 start control information with to the level detection start control information of analog to digital converter ADC2 totally two flag bits write among the EEPROM of sub-CPU; In when start, sub-CPU judges these two flag bits, if 1, then open corresponding port level detection power up function; If 0, then do not operate, press the normal mode start.
Task of the present invention comes to this and finishes.
The invention provides the on-off control method of a kind of double CPU TV set by the SCART interface.It had both adopted two CPU controls, can reduce power consumption, raise the efficiency, can allow the user pass through switching manipulation again to the audio ﹠ video equipment (as DVD or set-top box etc.) that is connected with the SCART interface with television set, the directly switching on and shutting down of control television set, and can pass through certain operation setting of remote controller with this function temporary close.It can be widely used in adopting in the television set in two CPU outlets Europe.
