Description
Technical field
The utility model relates to a kind of HDMI to the SDI transducer.
Background technology
Along with social development of science and technology; People to video quality require increasingly high; Video quality constantly develops from the SD to the high definition; Application like video formats such as HDMI, SDI is more and more general, to SDI equipment on the present stage market also be not very general and cost higher relatively, a plurality of if desired SDI equipment will occur causing cost too high because buying the cost of a plurality of SDI equipment.
The utility model content
In order to overcome the defective of prior art; The utility model discloses a kind of HDMI to the SDI transducer; It is integrated HDMI and SDI accepting device and SDI modulation output equipment can transfer 1 road HDMI signal to 4 road sdi signals and 1 road sdi signal transfers the multichannel sdi signal to, has practiced thrift cost.
The technical scheme of the utility model is following:
A kind of HDMI is to the SDI transducer, comprises 1 minute 4 unit of HDMI input interface, SDI input interface, HDMI signal conversion unit, sdi signal converting unit, sdi signal driver and signal, four road SDI output ports, control unit; Said HDMI input interface is connected with said HDMI signal conversion unit; Said SDI input interface is connected with said sdi signal driver and 1 minute 4 unit of signal.Said HDMI signal conversion unit is connected with the sdi signal converting unit; Said sdi signal converting unit is connected with sdi signal driver and 1 minute 4 unit of signal; 1 minute 4 unit of said sdi signal driver and signal is connected with four SDI output ports respectively; Said control unit is connected with said HDMI signal conversion unit, sdi signal converting unit respectively.
Compared with prior art, the beneficial effect of the utility model is following:
The utility model can realize that HDMI changeed 4 road SDI and sdi signal 1 minute 4, thereby has saved the cost of buying a plurality of SDI equipment, and it has not only utilized existing HDMI equipment to reduce the wasting of resources well, has also reduced the purchase cost of SDI equipment.
The utility model also has the following advantages:
The first, support 1 road HDMI input or 1 road SDI input, various video form (720P, 1080P etc.) is supported in 4 road SDI output.
The second, this equipment is the conversion of signals of numeral to numeral, disturbs for a short time, can well guarantee to be collected in the consistency of display frame.
The 3rd, self adaptation is supported different high definition resolution.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment HDMI to the SDI transducer.
Embodiment
The below combines accompanying drawing and specific embodiment that the utility model is done further description.
Embodiment
Like Fig. 1; A kind of HDMI is to the SDI transducer, comprises 1 minute 4 unit of HDMI input interface 11, SDI input interface 16, HDMI signal conversion unit 12, sdi signal converting unit 13, sdi signal driver and signal 15, four road SDI output ports 17, control unit 14.
HDMI input interface 11 is connected with HDMI signal conversion unit 12; SDI input port 16 is connected with sdi signal driver and 1 minute 4 unit 15 of signal.
HDMI signal conversion unit 12 is connected with sdi signal converting unit 13; Sdi signal converting unit 13 is connected with sdi signal driver and 1 minute 4 unit 15 of signal; 1 minute 4 unit 15 of sdi signal driver and signal is connected with four SDI output ports 17 respectively; Control unit 14 is connected with HDMI signal conversion unit 12, sdi signal converting unit 13 respectively.
Introduce the course of work of each unit below in detail:
S1:HDMI input interface 11 receives the HDMI signal in one tunnel external world, and it is transferred to HDMI signal conversion unit 12.
The HDMI conversion of signals that S2:HDMI signal conversion unit 12 receives is the signal of BT1120 agreement, and it is transferred to sdi signal converting unit 13.
S3:SDI signal conversion unit 13 will receive the sdi signal that conversion of signals is a pair of difference, and this is transferred to sdi signal driver and 1 minute 4 unit 15 of signal to signal.
1 minute 4 unit 15 of S4:SDI signal driver and signal converts the sdi signal of above-mentioned a pair of difference into the sdi signal of two pairs of difference.
S5: the sdi signal of two pairs of difference is respectively from 17 outputs of four road SDI output ports.
Wherein, control unit 14 is used to dispose reading of HDMI and SDI register and various information and shows.
During practical implementation, can also directly import the sdi signal in one tunnel external world, be converted into 4 road sdi signals from the SDI input interface.
In the present embodiment, working power is 12V, 2A, DC power supply.
Compared with prior art, the beneficial effect of the utility model is following:
The utility model can realize that HDMI changeed 4 road SDI and sdi signal 1 minute 4, thereby has saved the cost of buying a plurality of SDI equipment, this both use good use existing HDMI equipment reduced the wasting of resources, also reduced the purchase cost of SDI equipment.
The utility model also has the following advantages:
The first, support 1 road HDMI input or 1 road SDI input, various video form (720P, 1080P etc.) is supported in 4 road SDI output.
The second, this equipment is the conversion of signals of numeral to numeral, disturbs for a short time, can well guarantee to be collected in the consistency of display frame.
The 3rd, self adaptation is supported different high definition resolution.
The utility model preferred embodiment just is used for helping to set forth the utility model.Preferred embodiment does not have all details of detailed descriptionthe, does not limit this utility model yet and is merely described embodiment.Obviously, according to the content of this specification, can do a lot of modifications and variation.These embodiment are chosen and specifically described to this specification, is principle and practical application in order to explain the utility model better, thereby person skilled can be utilized the utility model well under making.The utility model only receives the restriction of claims and four corner and equivalent.More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection range.
