By using the utility model, multipath high-definition video signals input to the display terminal are switched easily through the switchers. Compared with the prior art, the utility model has the advantages of energy saving, low power consumption, strong antistatic capability and the like. Multiple HDMI high-definition video switchers can be connected in series or parallel to switch multipath input HDMI high-definition video signals.
Description
Technical field
The utility model relates to the HDMI technology, and particularly a kind of HDMI HD video equipment switched system is used for the mutual switching between the multi-path high-definition signal source.
Background technology
HDMI (High Definition Multimedia Interface) is that a kind of full digitisation image and sound transmit interface, can transmit audio signal and the vision signal of not having compression.HDMI can be used for equipment such as set-top box, DVD player, PC, holder for TV playing, comprehensive enlarger, numerical digit sound equipment and television set.And can transmit the Voice ﹠ Video signal simultaneously, because the Voice ﹠ Video signal adopts same cable, simplified the installation of system greatly.
Along with the improvement day by day of people's life, increasing family all has more than one high-definition signal source, for example blue-ray DVD, PC household PC, PMP (hand-held recreation terminal), SETBOX set-top box and DIGITAL CAMERA (camcorder) etc.And generally, in the time of these high-definition signal sources need being connected to a display terminal (as LCD TV or projecting apparatus), will have the not enough problem of HDMI interface of display terminal.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of HDMI HD video equipment switched system, to solve the not enough problem of HDMI interface that present multi-path high-definition signal source is connected on the display terminal and produce, realize the light switching between the multi-path high-definition signal source, made things convenient for user's selection.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of HDMI HD video equipment switched system, satisfy the HDMI1.3a standard, comprise a plurality of HDMI input ports, HDMI output port, display terminal, controller and at least one switch, described HDMI input port is connected with switch, described switch is connected by controller control and with the HDMI output port, and the HDMI output port is connected with display terminal.
Wherein said switch is preferably two.
Wherein said HDMI input port is preferably six.
Wherein this system also includes a switching button, and this switching key is connected with controller.
Wherein this system also includes an infrared receiver, and this infrared receiver is connected with controller.
Wherein said switch is the BU16018KV chip.
The utility model realizes that by switch the multi-path high-definition vision signal is input to the light switching of display terminal, compared with prior art, the utlity model has following beneficial effect:
1, energy-conservation, low in energy consumption: thus the switch master chip operating current that native system adopted only needs 120mA. to make the operating current maximum of entire product be no more than 150mA, and so low power consumption just can directly be powered by the 5V voltage of HDMI interface itself.Therefore but without external power adapter operate as normal just.Reached the purpose of energy-conserving and environment-protective.
2, antistatic height: what HDMI input port and HDMI output port adopted in this system is the interface method for designing of ground connection nearby, and the design antistatic effect of switch BU16018KV is 10KV, therefore can guarantee that this product has higher antistatic effect.
What 3, the utility model adopted is to advance one to go out HDMI HD video equipment switch circuit more, and its design is more reasonable, more energy-conservation.By a plurality of HDMI HD video switchs being carried out serial or parallel connection to realize the switching of multi-channel video signal.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Embodiment
Core concept of the present utility model is: the utility model outputs to the HDMI output port after passing through HDMI HD video switch by the HDMI high-definition video signal with the multichannel input, wherein in the HDMI high-definition video signal of selecting input, control selection by controller, and each output signal can only be one the tunnel, when one road signal outputs to display terminal, other several signals then can not be imported, and the selection of controller can be undertaken or by realizing by the pressure-controlled button by remote controller.
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1ly, Fig. 1 is a theory diagram of the present utility model.The utility model provides a kind of HDMI HD video equipment switched system, is mainly used in when realizing that the multi-path high-definition signal source is input to display terminal light switching each other.
The utility model mainly includes a plurality of HDMI input ports, be preferably six in the present embodiment, be INPUT1, INPUT2, INPUT3, INPUT4, INPUT5, INPUT6, HDMI output port OUTPUT, a display terminal HDTV, a controller IC 3 and at least one switch, be preferably two in the present embodiment, see IC1, IC2 among the figure.
Wherein said HDMI input port INPUT1, INPUT2, INPUT3 are connected with switch IC1; HDMI input port INPUT4, INPUT5, INPUT6 are connected with switch IC2, and described switch IC1, IC2 control by controller IC 3, and are connected with HDMI output port OUTPUT, and HDMI output port OUTPUT is connected with display terminal HDTV.
In addition, also include a key switch SW in the native system, an infrared receiver IR, described key switch SW is connected with controller IC 3 with infrared receiver IR, can realize switching between switch IC2, the IC1 by press of key switch SW, promptly the input state between may command INPUT1, INPUT2, INPUT3, INPUT4, each input signal of INPUT5, INPUT6 switches.Utilize remote controller to pass through infrared receiver IR and also can realize the control of controller IC 3 couples of switch IC2, IC1, the input state between INPUT1, INPUT2, INPUT3, INPUT4, INPUT5, the INPUT6 input signal is switched thereby reach.
What switch IC2, IC1 adopted is the BU16018KV chip, and as the master chip of HDMI HD video equipment switch, the operating current of this chip only needs 120mA.So just make the operating current maximum of entire product be no more than 150mA, and the 5V of so low power consumption by HDMI interface itself just can directly power.Therefore this system can get final product operate as normal without external power adapter, has reached the very purpose of energy-conserving and environment-protective.In addition, because the static of human body and the static and the spike of other signal source can cause damage to the interface of HDMI HD video equipment switch.Therefore require this system to have enough anlistatig abilities.And the antistatic of BU16018KV is 10KV, by the interface method for designing of ground connection nearby.Can guarantee that this system has the antistatic effect up to 10KV.
That is adopted in the utility model six advances one and goes out HDMI HD video equipment switch circuit and design more science, more energy-conservation.The master chip BU16018KV support three of HDMI HD video switch is advanced one and is gone out, and in this programme two HDMI HD video switchs are carried out parallel connection, realized entering and exporting of five road signals or six road signals, and when one of them HD video switch work, another one is not then worked, and greatly reduces job costs.
More than be that a kind of HDMI HD video equipment switched system provided by the utility model is described in detail, used specific case herein structural principle of the present utility model and execution mode are set forth, above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
