Abstract
The invention discloses a device for automatically identifying an insert signal source, which is used in televisions. The device comprises a television chip, a signal source input port and a signal wire input terminal, wherein a signal source automatic identification circuit is arranged between the television chip and the signal wire input terminal. The invention also discloses a method for automatically identifying an insert signal source, which comprises the following steps: a. when the signal wire input terminal is inserted into the signal source input port, the signal source automatic identification circuit detects the input/output port of the television chip; b. the corresponding relation between the signal wire input terminal and the port with which the television chip is connected, is judged according to the voltage change of the input/output port of the signal source input port; and c. the television is switched to the signal source input port channel which is currently inserted. The invention can automatically identify the terminal inserted into the signal wire and automatically switch to the corresponding channel, so that the user can use the television conveniently and can not be bothered by the connection problem of complicated signal wires.
Description
Technical field
The present invention relates to TV tech, relate in particular to the apparatus and method that information source is inserted in a kind of automatic identification that is used for TV.
Background technology
Traditional television information source need be checked specification or the prompting of the information source above television set silk-screen, holding wire could be inserted corresponding ports accurately.This structure must just can accurately be inserted corresponding port with holding wire to audio-video system is familiar for the people who uses TV.
Along with the continuous expansion of TV functions, signal port also increases thereupon, therefore, how to make the user not become an important topic for the holding wire connection worry of complexity.
Summary of the invention
The objective of the invention is to overcome above-mentioned problems of the prior art, propose the apparatus and method that information source is inserted in a kind of automatic identification that is used for TV.
The device that information source is inserted in the automatic identification that the present invention proposes comprises: TV chip, information source input port and holding wire input terminal.Be provided with an information source automatic identification circuit between described TV chip and the holding wire input terminal.
Described information source automatic identification circuit comprises the switch that is arranged in the information source input port, each information source input port of TV is connected to the I/O port of TV chip, as signal input pin, when the holding wire input terminal inserts, described switch disconnects or is closed, thus, in the variation that the I/O port that is connected with TV chip produces level, described information source automatic identification circuit switches to TV according to the voltage height of information source input port the information source input port passage of current insertion.
The method that information source is inserted in the automatic identification that the present invention proposes comprises the following steps:
A, when the holding wire input terminal inserts information source input port, the information source automatic identification circuit detects the I/O port of TV chip;
B, according to the I/O port change in voltage that the holding wire input terminal connects, judge the corresponding relation of holding wire input terminal and TV chip institute connectivity port;
C, TV switched to the holding wire input port passage of current insertion.
Compared with prior art, the present invention can automatically discern the holding wire input terminal of insertion, and automatically switches to the apparatus and method of respective channel, can make the user be convenient to use TV, and is no longer worried for the connectivity problem of the holding wire of complexity.
Description of drawings
The present invention will be described in detail below in conjunction with accompanying drawing and preferred embodiment, wherein:
Fig. 1 is the schematic representation of apparatus that the present invention proposes;
Fig. 2 is the schematic flow sheet of the method that proposes of the present invention.
Embodiment
The device that information source is inserted in the automatic identification that the present invention proposes comprises: TV chip, information source input port and holding wire input terminal are provided with an information source automatic identification circuit between TV chip and holding wire input terminal.This information source automatic identification circuit is connected to each information source input port of TV GPIO ((the General Purpose Input Output of TV chip, general I/O) mouth, as signal input pin, and TV is switched to the holding wire input port passage of current insertion according to the voltage of holding wire input port height.
As shown in Figure 1, be provided with a switch in the described information source input port, when the holding wire input terminal did not insert information source input port, the switch in the port was closed or disconnects; When the holding wire input terminal inserts information source input port, because of touching the switch in the port, this switch is disconnected or closure, thus, produce the variation of level on the GPIO mouth that is connected with TV chip, the information source automatic identification circuit switches to holding wire input port passage according to the height of voltage with TV.
As shown in Figure 2, the method for information source is inserted in the automatic identification that the present invention proposes, and comprises the following steps:
A, when the holding wire input terminal inserts information source input port, the information source automatic identification circuit detects the GPIO mouth of TV chip;
B, according to the GPIO mouth change in voltage that information source input port connects, judge the corresponding relation of the information source input port that the holding wire input terminal is connected with TV chip;
C, TV switched to the information source input port passage of current insertion.
The present invention is by increase information source automatic identification circuit between television signal line input terminal and TV chip, and supporting corresponding software, and when making the user that holding wire is inserted port, TV can be discerned automatically, and passage is switched to corresponding passage.
Hardware of the present invention is achieved in that each input port with TV is connected to the GPIO mouth (as signal input pin) of TV chip.When holding wire inserted, the voltage (according to the requirement of different chips and difference) of this PIN pin can be drawn high or drag down to the GPIO mouth, thereby the notice TV chip is which port has been connected.
Software implementation method of the present invention: use the establishment detection function in the information source identification circuit, the change in voltage of correspondence when GPIO mouth signal lines input terminal inserts, the corresponding relation of the PIN pin of the GPIO mouth that connects according to each port number and connection holding wire input terminal switches to TV in the information source input port passage of current insertion.
The present invention is very easy to the TV user, and they are just passable as long as the holding wire input terminal is inserted information source input port, need not be worried for judging complicated signal wire interface.
