Abstract
The utility model discloses an HDMI data distributor which is characterized by comprising a signal input port, four signal output ports, a TMDS receiver and a CPU, wherein the signal input port and the four signal output ports are respectively connected with the TMDS receiver; and the output port of the CPU is connected with the control end of the TMDS receiver. The signal distributor can divide a high definition 720P signal of YPbPr into four high definition signals, and also can distribute high definition HDMI signals of 1080P/1.3V.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of HDMI data distributor.
Background technology
Existing signal allocation equipment, the function that realizes is for being assigned to 1 road input signal arbitrary port of two-way output port, as shown in Figure 1, still, the shortcoming of this switching device is: can only switch analog signal, such as the color difference signal that can distribute YPbPr, the high definition picture that can not distribute data reaches 10Gbt, signals such as film, therefore, existing signal allocation equipment can not satisfy people's needs, is necessary existing signal allocation equipment is improved.
The utility model content
The utility model wants the technical solution problem to provide a kind of HDMI data distributor, this device can overcome the shortcoming of existing signal distributor, can distribute 1 road HDMI high definition input signal to 4 output port any or a plurality of on be sent to high-clear display again, 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 HDMI data distributor is characterized in that, comprises 1 signal input port and 4 signal output ports, TMDS receiver and CPU; Described 1 signal input port all is connected with the TMDS receiver with 4 signal output ports; The output port of described CPU connects the control end of TMDS receiver.
Described HDMI data distributor also comprises 4 signalling channel indicator lights that are used to indicate allocation result, and described signal lamp all is connected with CPU.
HDMI is the english abbreviation of high definition media interface, and TMDS is the english abbreviation of transition minimized differential signaling (electronic protocol).
The beneficial effects of the utility model:
Characteristics of the present utility model are to realize that by CPU control TMDS receiver 1 road input signal is assigned to 4 road output ports and is sent to high-clear display, has 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.Therefore, the utility model is practical, and is easy to implement, can satisfy the distribution requirement of high-speed data.
Description of drawings
Fig. 1 is existing signal distribution equipment structural representation;
Fig. 2 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 HDMI data distributor is characterized in that, comprises 1 signal input port and 4 signal output ports, TMDS receiver and CPU; Described 1 signal input port all is connected with the TMDS receiver with 4 signal output ports; The output port of described CPU connects the control end of TMDS receiver.Described HDMI data distributor also comprises 4 signal lamps that are used to indicate allocation result, and described signal lamp all is connected with CPU.
As shown in Figure 2, this product (being the HDMI data distributor) needs the 5V/1.2A power supply, and power supply is from the input of power input mouth, through offering cpu controller and TMDS receiver after the power regulator voltage stabilizing.During use, signal source is received signal input port, again 4 signal output ports are received the high-definition signal display respectively with producing.By cpu controller control signal is delivered to the batch operation that the TMDS receiver is carried out signal, cpu controller also will distribute channel information to pass to the signalling channel indicator light to come index signal and corresponding passage connection simultaneously.The TMDS receiver is assigned 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 also can distribute the high definition HDMI signal of 1080P/1.3V to the high definition 720P signal allocation of YPbPr.
This product can link use with the high definition product of HDMI.As, with the high definition DVD that has the HDMI port, have the computer of HDMI port, have the HDTV of HDMI port, have the projector of HDMI port, have the high definition mobile phone of HDMI port, have the high definition camera of HDMI port etc.This product links use except the high definition product with HDMI, can also link use with the electric equipment that DVI is arranged.As, with the high definition projector that has the DVI port, have the computer of DVI port, have the display of DVI port, have the high definition camera of HDMI port etc.This product can connect 4 display devices such as digital TV in high resolution simultaneously.
Claims (2)
