Abstract

The utility model discloses a Display Port signal selector, which comprises at least two input modules (1) for inputting audio and video signals, a switching module (2) for receiving the audio and video signals and carrying out output switching, an output module (3) for outputting the audio and video signals, a receiving module (4) for receiving operator switching instructions, a driving module (5) respectively connected with the input modules, the output module and the receiving module, and for gating the input module according to the switching instructions, and a power supply module (6) for supplying power to the above modules. Compared with the prior art, the Display Port signal selector can carry out selection to multiple Display Port input signals, select an appointed high definition video output device according to user instructions, and transmits the Display Port signals to a display device, such as a television set, and the like.

Description

A kind of Display Port signal selector

Technical field

The utility model relates to signal selector, relates in particular to a kind of selector of multichannel Display Port input signal being selected an output.

Background technology

There is multiple HD video output equipment (as: blue-ray DVD, high definition digital camera, computer etc.) progressively to be converted into Display Port interface in family or the market now, when these equipment need be connected to when televising, because the television set input interface is limited, need to change the incoming line that connects television set, use very inconvenient.A kind of selector is needed in market badly, and multichannel Display Port input signal is selected, and connects television set with the picture output device of selecting appointment.

The utility model content

The utility model is the problems referred to above that will solve prior art, proposes a kind of multichannel Display Port input signal to be selected, and selects the selector of an output.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of Display Port signal selector of design, it comprises: two-way is imported the input module of audio-video signal at least, receive the audio-video signal handover module that line output switches of going forward side by side, the output module of output audio-video signal, receive the receiver module of operator's switching command, connect input module, output module, receiver module respectively and according to the driver module of switching command gating input module, and to the power module of each module for power supply.

Wherein power module comprises external direct current 5V power supply and is 3.3 volts of power converting circuits of direct current 3.3V with external direct current 5V power conversion.

Wherein receiver module comprises press key input device.

Wherein receiver module comprises remote control signal receiver.

Compared with prior art, the utility model can be selected multichannel Display Port input signal, selects the HD video output equipment of appointment according to user instruction, and its Display Port signal is transferred to display unit (as television set etc.).

Description of drawings

Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:

Fig. 1 is the theory diagram of the utility model preferred embodiment;

Fig. 2 is the power module of the utility model preferred embodiment;

Fig. 3 is the circuit diagram of the utility model preferred embodiment.

Embodiment

The utility model discloses a kind of Display Port signal selector, it comprises referring to Fig. 1: two-way is imported the input module 1 of audio-video signal at least, receive the audio-video signal handover module 2 that line output switches of going forward side by side, the output module 3 of output audio-video signal, receive the receiver module 4 of operator's switching command, connect input module, output module, receiver module respectively and according to the driver module 5 of switching command gating input module, and to the power module 6 of each module for power supply.

In preferred embodiment, power module 6 comprises external direct current 5V power supply and is 3.3 volts of power converting circuits of direct current 3.3V with external direct current 5V power conversion.As can be seen from Figure 2, power module is by introducing 5 volts of direct currents among the plug DC, and the 5V power supply is powered to segment chip, and pressure regulation chip AMS1117-3 is transformed to 3.3 volts of direct currents with direct current 5V.C1 to C7 is a power filtering capacitor.Receiver module comprises press key input device and remote control signal receiver.

Circuit diagram referring to the preferred embodiment shown in Fig. 3, elder generation is at two input interface (J1 of input module 1 during use, J2) locate to connect two playing audio/videos of exporting Display Port signals, the operator is by press key input device 8 or remote control signal receiver 7 inputting switching commands in the receiver module 4, receiver module 4 is transferred to driver module 5 with switching command, driver module 5 is by input interface J1, J2 sends the gating control level, one of them is transferred on the output module 3 by the Display Port signal in the interface of gating handover module 2 with J1 or J2, output module 3 connects television set, thus the program in the television for play designated tone video playback apparatus.

Above embodiment is only for illustrating non-providing constraints.Anyly do not break away from the utility model spirit and category, and, all should be contained among the application's the claim scope its equivalent modifications of carrying out or change.
