Description
Technical field
The present invention relates to field of display devices, particularly relate to a kind of numeric display unit for decoding.
Background technology
Numeric display unit is the display for display digit signal, such as devices such as telescreens, for digital signal
Display, be unable to do without decoder module effect.Along with the development of science and technology, extensive with the numeric display unit that video information is characterized
Be applied to all trades and professions, meanwhile, the resolution of video and way are required more and more higher, but numerical monitor dress at present
The resolution that the decoder module put is supported is low and way is few, is difficult to meet requirement.
And current decoder module generally arranges single network interface, when this network interface hardware breaks down, then
The reception that can cause data stream is interrupted, and affects the display of numeric display unit.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of numeric display unit for decoding, can support multichannel
The decoding of 1080P digital signal, and the unimpeded of input signal when decoder module decodes can be ensured.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of numeral for decoding

Disturb unit, decoding unit and HDMI output interface；Interface unit is connected with main control module, and the quantity of interface unit is many
Individual；Interface unit is for input 4 road 1080P digital signals, and Descrambling unit is for descrambling digital signal, and decoding unit is used
In being decoded the digital signal after descrambling, HDMI output interface is for exporting decoded digital signal to master control molding
Block；Main control module is used for driving display module to show decoded digital signal.
Wherein, the quantity of interface unit is 2.
Wherein, decoder module utilizes individual interface unit to carry out the transmission of digital signal.
Wherein, decoder module is the most normal for the signal transmission judging interface unit, when judging transmission abnormality, and switching
To another interface unit.
Wherein, HDMI output interface is replaceable interface.
The invention has the beneficial effects as follows: be different from the situation of prior art, the numerical monitor dress for decoding of the present invention
Put and include main control module, decoder module and display module, interface unit that decoder module includes being sequentially connected with, Descrambling unit,
Decoding unit and HDMI output interface.Wherein, interface unit is connected with main control module, and the quantity of interface unit is multiple.
Wherein, interface unit is for input 4 road 1080P digital signals, and Descrambling unit is used for descrambling digital signal, decoding unit
For being decoded the digital signal after descrambling, HDMI output interface is for exporting decoded digital signal to main control
Module, main control module is used for driving display module to show decoded digital signal.By the way, the present invention is used for solving
The numeric display unit of code can support the decoding of 4 road 1080P digital signals, and can ensure input signal when decoder module decodes
Unobstructed.
Accompanying drawing explanation
Fig. 1 is the present invention structural representation for numeric display unit one embodiment of decoding.
Detailed description of the invention
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 1 is the present invention structural representation for numeric display unit one embodiment of decoding, such as Fig. 1
Shown in, including: main control module 10, decoder module 20 and display module 30, decoder module 20 includes the interface list being sequentially connected with
Unit 21, Descrambling unit 22, decoding unit 23 and HDMI output interface 24.
Wherein, interface unit 21 is connected with main control module 10, and the quantity of interface unit 21 is multiple, is preferably provided with 2
Individual.
The work process of above-mentioned each module is particularly as follows: interface unit 21 is for input 4 road 1080P digital signals, and descrambling is single
The digital signal of input is descrambled by unit 22, and the digital signal after descrambling is decoded by decoding unit 23, decoded number
Word signal is exported by HDMI output interface 24；After main control module 10 receives the digital signal of decoder module 20 output, drive
Dynamic display module 30 shows decoded digital signal.
In actual applications, the numeric display unit for decoding of the present embodiment is embodied in the digital screen of TV,
For showing TV signal.
Wherein, descrambling is for scrambling, and scrambling is the characteristic changing standard television signal, unauthorized to prevent
User receive picture-and-sound clearly, descrambling is that scrambled TV signal is reverted to standard television signal.Scrambling
Process be by multiplexing after transmission stream and a pseudorandom scrambling sequence carry out mould two and add computing, the generation of this pseudo-random sequence by
The control word that control word generator provides determines, the core that digital television conditional receives is exactly that the transmission to control word is controlled
System.
Wherein, interface unit 21 is Ethernet interface, its type have RJ-45 interface, RJ-11, SC optical fiber interface,
Fddi interface, bnc interface etc..
In the present embodiment, decoder module 20 utilizes individual interface unit 21 to carry out the transmission of digital signal, why sets
Put 2 interface units 21, if being to prevent from only arranging an interface unit 21, when it breaks down, connecing of whole digital signal
Receipts will be interrupted.
Wherein, decoder module 20, during decoding, when judging the signal transmission abnormality of interface unit 21, switches to
Another interface unit 21 carries out the transmission of digital signal.
In the present embodiment, HDMI output interface 24 is replaceable interface, can the most directly change interface board, and
When interface damages, convenient maintenance.
Wherein, HDMI(High Definition Multimedia Interface, HDMI) be
A kind of digitized video/audio interface, for the special digital interface of applicable image transmission, can transmit audio frequency and image letter simultaneously
Number.
In sum, the present invention can support the decoding of 4 road 1080P digital signals for the numeric display unit decoded, and
When can ensure decoding, input signal is unimpeded.High-resolution numeric display unit makes picture become apparent from, screen fineness
Higher, improve Consumer's Experience.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description and accompanying drawing content are made convert, or are directly or indirectly used in other relevant skills
Art field, is the most in like manner included in the scope of patent protection of the present invention.
