Abstract
The utility model discloses a data integration switcher with multiple input channels, and is characterized in that the switcher comprises three signal input ports, a signal output ports, a TMDS receiver, a CPU and a change-over switch for switching between input signals; the three signal input ports and the signal output port are connected with the TMDS receiver; the output port of the CPU is connected with the control end of the TMDS receiver; and the input port of the CPU is connected with the change-over switch. The switcher can realize VPbPr high definition 720P signal switching as well as 1080P/1/3V high definition HDMI signal switching while providing simultaneous switching of three input signals to one output signal.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of data integration switch with multiple input path.
Background technology
Existing signal switching apparatus, can only switch analog signal, such as the color difference signal that can switch YPbPr, the high definition picture that can not switch data reaches 10Gbt, signals such as film, therefore, existing signal switching apparatus can not satisfy people's needs, is necessary existing signal switching apparatus is improved.
The utility model content
The utility model wants the technical solution problem to provide a kind of data integration switch with multiple input path, this device can overcome the shortcoming of existing signal shifter, can switch 3 road HDMI high definition input signal to an output port [being sent to high-clear display], easy to implement.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of data integration switch with multiple input path is characterized in that, comprises 3 signal input ports and signal output port, TMDS receiver, a CPU and is used for the change over switch of switched input signal; Described 3 signal input ports all are connected with the TMDS receiver with a signal output port; The output port of described CPU connects the control end of TMDS receiver, and the input port of described CPU connects the conversion switch.
The Chinese of HDMI is the english abbreviation of HDMI (High Definition Multimedia Interface), and TMDS is the english abbreviation of transition minimized differential signaling (electronic protocol).
Described data integration switch with multiple input path also comprises infrared remote receiver and 3 signal lamps that are used to indicate switching result, and described infrared remote receiver is used to indicate the signal lamp of switching result all to be connected with CPU with 3.
The beneficial effects of the utility model:
Characteristics of the present utility model are to realize that by CPU control TMDS receiver 3 road input signals freely switch to output port and are sent to high-clear display, have solved the indeterminable technical barrier of prior art.This programme is provided with indicator light, and which signal can indicate the current signal of user immediately is.This device is provided with manually and the instruction input mode of remote control, is user-friendly to.Therefore, the utility model is practical, and is easy to implement, can satisfy the switching requirement of high-speed data.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
A kind of data integration switch with multiple input path is characterized in that, comprises 3 signal input ports and signal output port, TMDS receiver, a CPU and is used for the change over switch of switched input signal; Described 3 signal input ports all are connected with the TMDS receiver with a signal output port; The output port of described CPU connects the control end of TMDS receiver, and the input port of described CPU connects the conversion switch.Described data integration switch with multiple input path also comprises infrared remote receiver and 3 signal lamps that are used to indicate switching result, and described infrared remote receiver is used to indicate the signal lamp of switching result all to be connected with CPU with 3.
As shown in Figure 1, this product needed 5V/1.2A power supply, power supply are from the input of power input mouth, through offering cpu controller and TMDS receiver after the power regulator voltage stabilizing.During use, the user connects 3 input interfaces of high-definition signal source to this product respectively with 3 tunnel inputs, and the receiving equipment that will be used for the high-definition signal demonstration is received output port.User's remote control or press change over switch, just receive user's instruction or pass to cpu controller by infrared receiver earlier by the instruction of change over switch input, by cpu controller control signal is delivered to the handover operation that the TMDS receiver is carried out signal again, the while cpu controller also passes to switching channel information signal switching indicator light and comes index signal and corresponding passage connection.The TMDS receiver switches to output port to deliver to the high definition receiving equipment with the signal [being the input signal of this product] of pairing high-definition signal source device.This product can switch the high definition 720P signal of YPbPr, also can switch the high definition HDMI signal of 1080P/1.3V.
Claims (2)
