Embodiment
The present invention is a kind of control chip module and control method thereof, can utilize microprocessor to receive the information that is transmitted by network and is shown on the display panel of display, and then improve the just pure function that shows done of known display.
See also Fig. 2, the hardware structure block diagram that it is connected with a remote-control device for the display of preferred embodiment of the present invention.As shown in the figure, display 20 of the present invention can be connected with a remote-control device 24 by network 23, and in order to the information that receiving remote device 24 is exported, its framework mainly comprises display panel 21 and control chip module 22.Wherein, the information that control chip module 22 can come receiving remote device 24 to be exported by network 23, and the display panel 21 that the content of this information stored and be sent to display 20 shown.The core component of this control chip module 22 mainly comprises video decoder 111, release of an interleave scanner 112, scale controller 113, processor, screen treatment circuit, selector switch and storage unit etc.Because the framework and the principle of video decoder 111, release of an interleave scanner 112 and scale controller 113 belong to known technology, therefore repeat no more.
Please consult Fig. 2 again, in this embodiment, processor is a microprocessor (microprocessor) 221, and its major function is the information that network 23 is sent that is received from, and produces first control signal and second control signal according to the information that is received.Storage element can be dynamic RAM (RAM) 224, and it is subjected to first control signal control of microprocessor 221 and the content of information is stored in the specific region of microprocessor 221 appointments.The screen treatment circuit is good with on-screen display circuit (OSDCircuit) 222 then, it is controlled by second control signal of microprocessor 221 mainly, and read the content of appointed information in the specific region of the dynamic RAM 224 that arrives, and be shown on the display panel of display 20 21 after the content of this information handled by scale controller 113.
In addition, during for fear of microprocessor 221 and on-screen display circuit 222 random access memory 224 of access simultaneously signal being produced conflicts, control chip module 22 can be provided with a selector switch, multiplexer (Multiplexer) 223 for example, in microprocessor 22 1, between on-screen display circuit 222 and the random access memory 224, to implement the arbitration (Bus Arbitration) of bus, one of them deposits or reads the step of this information to dynamic RAM 224 can to select to permit microprocessor 221 or on-screen display circuit 222 by this, and then signal is produced when avoiding microprocessor 221 with on-screen display circuit 222 random access memory 224 of access simultaneously to conflict.
Please consult Fig. 2 again, the correctness of start picture when guaranteeing to start shooting, control chip module 22 also can be set up a ROM (read-only memory) (ROM) 225, and it is electrically connected with microprocessor 22 1.Because the content of dynamic RAM 224 is mess codes at random during electric power starting, it is not effective content, therefore microprocessor 221 must be according to the content of ROM (read-only memory) 225 when start, the mode that basic input and output system duplicates (BIOS Shadowing) during with similar computer booting, producing start picture inserts in the random access memory 224, and control on-screen display circuit 222 is shown in start picture on the display panel 21 correctness of start picture content when guaranteeing to start shooting.
Certainly, in the foregoing description, display can be cathode-ray tube TV (CRT TV), CRT monitor (CRT Monitor), LCD TV (LCD TV), LCD monitor (LCDMonitor), plasma television (Plasma TV), plasma monitor (Plasma Monitor), projection TV (Projector TV) or projection monitors (Projector Monitor).In addition, network 23 can be world-wide web, Ethernet (Ethernet), wireless network, USB (universal serial bus) (USB), fire-wire interfaces (Fire Wire) or Packet Switching Network PSN etc.
See also Fig. 3, the hardware structure block diagram that it is connected with a computing machine for the display of another preferred embodiment of the present invention.As shown in the figure, display 20 of the present invention is except that display panel 21 and control chip module 22, also can comprise a peripheral assembly connecting interface bridge (PCI Bridge), be used for carrying out the transmission of data with the peripheral assembly connecting interface network card (PCI NIC) 261 of a switch 26.Display 20 can utilize grid line to be connected between the two with switch 26 or adopt wireless (wireless) transmission manner to connect.
In this embodiment, switch 26 is online by Ethernet 27 and computing machine 28, just can be in regular turn when computing machine 28 produces information information be sent to the microprocessor 221 of control chip module 22 via peripheral assembly connecting interface bridge (the PCI Bridge) 25 of the peripheral assembly connecting interface network card (PCI NIC) of Ethernet 27, switch 26 and display 20, and the running by other circuit, and then this information dynamically is stored in the dynamic RAM 224, or the content of information is shown on the display panel of display 20 21.Certainly, the content of information can be coloured image, sound bite or video image content etc.
See also Fig. 4, it is for using the process flow diagram of control chip module controls display display message content of the present invention.At first, microprocessor 221 receives the information of being exported by remote-control device 24 by network 23, and produces first control signal and second control signal (step S40).Then, multiplexer 223 selects to permit microprocessor 22 1 with information storage (step S41) in the specific region of dynamic RAM 224.Subsequently, multiplexer 223 is selected to permit on-screen display circuit 222 and to the specific region of dynamic RAM 224 content of information is read (step S42).At last, the content of information is shown in 21 (step S43) on the display panel of display 20 after handling by scale controller 113 again.By the control flow of control chip module of the present invention, just the transmission of the information that remote-control device 24 can be exported by network 23 is stored in the dynamic RAM 224 or directly is shown on the display panel 21 of display 20.
In sum, control chip module of the present invention and control method thereof can be under the situations that does not have extra vision signal input, reach the function that directly shows information that remote-control device transmits by network, can improve the just pure defective of doing demonstration of known display by this in display.In addition, because control chip module of the present invention is set up a dynamic RAM, make the information content be able to dynamic change.And the setting of control chip module of the present invention by a multiplexer can be carried out the arbitration of bus, solves microprocessor and on-screen display circuit while contingent signal conflict during access information.
The present invention must be appointed by those skilled in the art and executes that the craftsman thinks and be to modify the protection domain of right neither disengaging claims as all.
