Abstract
The utility model relates to an all-in-one machine of television and computer. The all-in-one machine of television and computer includes a computer function module and a television function module integrated on a main board. A bridge chip PS2 interface in the computer function module communicates with a PS2 interface circuit of the television function module. The television function module includes a master control module, an infrared receiving module and the like. The infrared receiving module receives a remote controller instruction and transmits to the master control module. If the remote controller instruction is judged to be a television signal by the master control module, corresponding operations are performed according to the instruction. If the remote controller instruction is judged to be a computer signal, the computer signal is transmitted to the computer function module through the PS2 communication interface circuit for processing. In the utility model, the computer function module and the television function module are integrated on the same PCB, thereby reducing connection lines between the two modules. And since the two modules communicates in a PS2 form, the master control module of the television function module is adopted as a control core, and the remote control is realized through a computer and a television, the switching is convenient, and operations of television playing, PIP, movements of television PIP in any position of a computer desktop and the like are realized.
Description
Technical field
The utility model relates to a kind of DTV, especially relates to a kind of television PC.
Background technology
Along with popularizing of DTV, existing most of television PCs all are merely able to support computer function, and can't support TV functions.Perhaps also have by computer function plate and TV integrated circuit board, each functional part of set-top box functionality plate independently to merge the computer and television integrated machine that forms, but it can only realize the simple switching of function between TV and the computer, can't satisfy user's diversified demand; Connecting line is complicated and tediously long between each feature board simultaneously, poor anti jamming capability, and be difficult for maintenance maintenance.
Summary of the invention
The problem that the utility model need solve provides a kind of television PC.
For addressing the above problem; The technical scheme that the utility model adopts is: a kind of television PC; Comprise mainboard, remote controller; Be integrated with computer function module and TV functions module on the said mainboard, said TV functions module comprises the PS2 interface circuit, and this PS2 interface circuit is connected with north and south bridge chip group in the computer function module.
As preferably; Said TV functions module also comprises main control unit, infrared receiver; Said infrared receiver is connected with main control unit, and main control unit is connected with the PS2 interface circuit, and infrared receiver receives remote command and is transferred to main control unit; Main control unit judges it is that the TV signal instruction is then carried out TV functions module corresponding operating according to instruction, is that the pcs signal instruction is then given the computer function resume module through PS2 communication interface circuit transmission.
As preferably, said remote controller is for adopting the remote controller of PS2 data frame format, and its instruction is sent with PS2 data frame format coding.
Compared with prior art; The said television PC of the utility model is integrated in computer function module and TV functions module on the pcb board; Reduce the loaded down with trivial details line between the two, and two modules being with conveniently PS2 form communication, serves as the control core with the main control unit of TV functions module; Through remote controller control main control unit, and then make the easy switching between TV and the computer.Realization is televised, PIP (picture-in-picture), computer media player, mail reception, and TV PIP such as moves at operation in any position of computer desktop.
Description of drawings
Fig. 1 forms schematic block diagram for the utility model principle.
Embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is done further to specify below in conjunction with embodiment and accompanying drawing.
Like Fig. 1; The computer and television integrated machine that the utility model disclosed comprises mainboard, remote controller; Be integrated with computer function module and TV functions module on the mainboard; Wherein the computer function module is mainly by north and south bridge chip group, and comprises that other function module circuit of core cpu control chip, north and south bridge chip group, internal memory, video card etc. constitutes.The TV functions module comprises main control unit, the PS2 interface circuit that adopts the core cpu control chip, and other element circuit that comprises circuit such as CA interface unit, tuning demodulator.
The north and south bridge chip group of computer function module is connected through the PS2 communications protocol with the PS2 interface circuit of TV functions module carries out data passes.North and south bridge chip group is the traditional die group framework of computer main board; South Bridge chip generally is positioned on the computer main board from CPU slot below far away; Near the PCI slot, this layout is to consider that the I/O bus that it connects is more, a little further helps wiring from processor.General north bridge chips is responsible for the exchanges data between CPU and internal memory, the video card, and data processing amount is big, needs the configuration fin.South Bridge chip generally is responsible for the communication between the I/O bus, like pci bus, USB, LAN, ATA, SATA, Audio Controller, KBC, real-time clock controller, APM etc., does not cover fin as the one of which; South Bridge chip does not directly link to each other with processor, but links to each other with north bridge chips through certain mode.
The utility model is provided with infrared receiver in the TV functions module, this infrared receiver cooperates with remote controller, and remote command is sent with PS2 data frame format coding.Infrared receiver receives the main control unit that remote command is transferred to the TV functions module; Judge through TV functions module main control unit; If what receive is TV signal then directly carries out the corresponding operating to TV functions according to instruction; If pcs signal then is transferred to the computer function resume module through PS2 communication interface circuit with instruction, carry out computation according to instruction by the computer function module.Here TV signal generally comprises program key, preview key, volume add-substract key of TV etc.; Pcs signal comprises functions such as computer multi-media play button, F.F., rewind down, web page browsing, mail are browsed, transmitting-receiving; Concrete function is determined by the related definition in the computer BIOS; Same group of button can be distinguished corresponding computer or television function on the remote controller, and the switching of carrying out PC pattern and TV pattern through remote controller gets final product.
Need to prove, more than be merely the utility model preferred embodiment, do not breaking away under the utility model design prerequisite any impartial protection range of in the prior art scope, the utility model circuit being done that all belongs to the utility model with modification that changes.
Claims (3)
1. television PC; Comprise mainboard, remote controller; It is characterized in that being integrated with on the said mainboard computer function module and TV functions module, said TV functions module comprises the PS2 interface circuit, and this PS2 interface circuit is connected with north and south bridge chip group in the computer function module.
2. a kind of television PC according to claim 1; It is characterized in that said TV functions module also comprises main control unit, infrared receiver; Said infrared receiver is connected with main control unit; Main control unit is connected with the PS2 interface circuit; Infrared receiver receives remote command and is transferred to main control unit, and main control unit judges it is that the TV signal instruction is then carried out TV functions module corresponding operating according to instruction, is that the pcs signal instruction is then given the computer function resume module through PS2 communication interface circuit transmission.
