Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the scene schematic diagram that the embodiment of the present invention is suitable for.
Display device is connected with HDMI switch output port, and HDMI switch input port HDMI1 to HDMIn is connected with n media player respectively, and described n is the positive integer more than or equal to 1.
The HDMI switch adopts the two-way Power supply, one the tunnel is the DC5V DC power supply that provides for main frame, other one tunnel pin18 pin for HDMI switch input port provides the 5V power supply, even powered-down does not affect the normal operation of HDMI switch yet like this, as long as there is the input of HDMI vision signal just can work.
The HDMI switch can carry out multichannel HDMI vision signal and switch, the built-in HDMI signal processing chip of described HDMI switch receives a plurality of HDMI vision signal inputs simultaneously, the HDMI signal that can carry out multichannel switches, the HDMI signal processing chip receives the input of a plurality of HDMI vision signals simultaneously, and selects wherein one the tunnel as output.The HDMI vision signal is imported the HDMI signal processing chip into from media player (as DVD), the register of HDMI signal processing chip can read the port numbers etc. of on line state (on line state refers to the connection status of HDMI switch and media player), signal condition (signal condition refers to whether each media are provided to the signal of HDMI exchange normal), input time and the use of each road HDMI vision signal, then wait for that the built-in micro-control unit of HDMI switch (Micro Control Unit, MCU) chip obtains.the built-in MCU chip of HDMI switch plays the real-time control action of function, and (in real time control action refers to that described MCU working frequency of chip is less than inferior/0.5 second here, close to fully in real time), obtain the on line state of each road HDMI vision signal from the register of HDMI signal processing chip by communication interface, signal condition, the port numbers of input time and use, search the normal HMDI vision signal of on line state and signal condition, in on line state and the normal signal of signal condition with input time HDMI vision signal the latest find out, generate HDMI vision signal output command, described vision signal output command carries the sign of the input time of HDMI vision signal the latest, the MCU chip can be kept at the information of obtaining and the information that processing obtains in the RAM of MCU chip, final HDMI signal processing chip is according to described vision signal output command, with described input time HDMI vision signal the latest send to display device by HDMI OUT port.
When the media player that therefore need to watch as the user is opened, restart media player by remote controller, namely the HDMI vision signal of media player can be outputed to display device, when the media player that need to watch as the user is in closed condition, use a teleswitch and directly open media player, HDMI vision signal on display device just can output to display device, reached the effect of selecting very simply input signal, solved prior art and switched the pretty troublesome problem of different media players by remote control.
Need to prove, the embodiment of the present invention is not limited to the HDMI interface just take HDMI interface (HDMI signal) as example describes, and can also be other interfaces and the signals such as analog video interface, DVI interface, VGA interface.
The method that the embodiment of the present invention provides input signal to select, described method as shown in Figure 2, concrete steps comprise:
S11, receive a plurality of input signals.
