Utility model content
The utility model provides a kind of signal distributor based on HDMI, can address the above problem.
A kind of signal distributor based on HDMI that the utility model embodiment provides, control module, for connecting the HDMI input interface of HDMI signal source equipment, for the HDMI signal that HDMI input interface is received, be converted to the HDMI transceiver module of the Y/Cb/Cr signal that includes row field sync signal and a plurality of for described Y/Cb/Cr signal being converted to the HDMI output module of HDMI signal, on each HDMI output module, connect respectively a HDMI output interface, control module connects respectively HDMI transceiver module and HDMI output module, in control module, be connected with respectively display screen and control panel, described control panel is provided with a plurality of control buttons that equate with HDMI output module quantity.
Preferably, described HDMI transceiver module adopts ANX9011 chip, and described HDMI output module adopts ANX9030 chip.
Preferably, HDMI transceiver module quantity is one, and the quantity of HDMI output module is four.
Technique scheme can be found out, because adopting control button, the utility model embodiment, by control module, certain idle HDMI output module is shielded to control, therefore, can control easily the output of a certain road HDMI signal, realize the controllable function of distributor, avoided the wasting of resources.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the electrical block diagram of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The utility model embodiment provides a kind of signal distributor based on HDMI, as shown in Figure 1, control module, for connecting the HDMI input interface of HDMI signal source equipment, for the HDMI signal that HDMI input interface is received, be converted to the HDMI transceiver module of the Y/Cb/Cr signal that includes row field sync signal and a plurality of for described Y/Cb/Cr signal being converted to the HDMI output module of HDMI signal, on each HDMI output module, connect respectively a HDMI output interface, control module connects respectively HDMI transceiver module and HDMI output module, in control module, be connected with respectively display screen and control panel, described control panel is provided with a plurality of control buttons that equate with HDMI output module quantity.
Wherein, in Y/Cb/Cr signal, Y-signal is luminance signal, and Cb/Cr signal is color difference signal, and those skilled in the art can obviously be known, repeat no more herein.
HDMI transceiver module described in the utility model embodiment adopts ANX9011 chip, and described HDMI output module adopts ANX9030 chip.
In the utility model embodiment, selecting the ANX90xx series IC of ANALOGIX company is based on Wide Eye signal recovery technology because of this product, thereby can provide high performance transmission or receiving ability, concrete parameter refers to this chip series handbook, does not repeat herein.This family chip can be supported the HDMI cable high speed transmission of signals much larger than the 15m of HDMI standard definition.Its actual support distance has surpassed 50m.Superpower driving transmittability allows client to use cheap cable (as UTP etc.) to carry out the transmission of high-speed multimedia signal, has also guaranteed the extremely low error rate simultaneously.ANX90xx family chip has very strong audio frequency and video disposal ability.This family chip can, with the speed rates of the highest 165Mpix/s up to 24 information datas, make whole processing frequency range approach 4Gb/s.It supports the conversion between RGB and various modes Y/Cb/Cr, supports the highest support of HDTV(1080p) and the highest support 1600 * 1200Hz of PC() application, also support 24 high accuracy number audio frequency outputs of 8 passage, I2S and S/PDIF standard output interface are provided.It not only can meet current state-of-the-art application, also possesses certain extended capability.ANX9030 chip is the transmission chip with HDCP, compatible with HDMI 1.2.Can support as number rate 165Mpix/s.To 720P and 1080i pattern, its power consumption is only 300mW.
