The quality of programme content and quantity can be made perfection and bring more programs to select for user and more preferable save by technology
Mesh mass effect, digital television system can transmit multiple business, such as high-definition television (being abbreviated as " HDTV " or " high definition "),
Standard definition television (being abbreviated as " SDTV " or " SD "), interactive TV, BSV be liquid crystal-spliced and data service etc..With mould
Intend TV to compare, DTV has picture quality height, program capacity (is 10 times of analog television transmission passage program capacity greatly
More than) and the good feature of sound accompaniment effect.
Coax transmission technology is a kind of interfacing of new release, and this new interfacing adopts optical fiber or coaxial electrical
Cable material (Coax cable) carries out the serial transmission of data.View data transmission can be realized by this cable, I/O interface controls, carries
Power supply source lamp function.This transmission technology has transmission range length (170 meters), and data volume is big (6.25Gbit/s), can concentrate solution
The certainly transmission speed of various coffrets at present, the various problem such as transmission range and transmission stability.In simulated television system
Parsing and the transmission of high-definition data cannot be realized, and the data based on HDMI is input to simulated television end as signal source
When it is impossible to realize the possibility of data transfer.
Utility model content
For overcoming the deficiencies in the prior art, the utility model provide a kind of simulation of COAX interface regard machine, by
Access COAX transmission mode between HDMI and image signal processing chip, realize transmission work(on simulated television for the high-definition data
Energy.
The utility model provides a kind of simulated television of COAX interface, including：HDMI, and and HDMI
Be connected COAX interface then, and the BCN coaxial connector being connected with described COAX interface, described BCN coaxial connector and
COAX decoder connects, and described COAX decoder is connected with way selectors, and described way selectors one end is connected to image letter
Number process chip, one end is connected to high-definition signal processing module, and described image signal processing chip is with common CRT display terminal even
Then.
Described high-definition signal processing module is made up of integrated circuit.
Described high-definition signal processing module adopts PW52 type integrated circuit to constitute.
Compared with prior art, the utility model, while the receiving data of HDMI port, is realized inside simulated television
The improvement of COAX transmission technology, realizes data transfer on high-definition interface, is processed by means of the high-definition signal increasing on simulated television
Module and way selectors, high-definition signal processing module is connected with image signal processing chip, and way selectors are believed with image
Number process chip connects, and the digital high-definition signal that HDMI port transmission comes can be converted to the image of existing simulated television
The signal that signal processing chip can be processed, that is, maintain simulated television technology maturation, reduces improving cost, also can meet mould
Intend the demand that digital cable customers watch digital high-definition signal.
Brief description
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the COAX interface simulated television in the utility model embodiment.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work
The all other embodiment being obtained, broadly falls into the scope of the utility model protection.
Accordingly, Fig. 1 shows the simulated television of the COAX interface in the utility model embodiment, specifically includes：
HDMI, and the COAX interface then that is connected with HDMI, and the BCN coaxial connector being connected with COAX interface,
This BCN coaxial connector is connected with COAX decoder, and this COAX decoder is connected with way selectors, this way selectors one end
It is connected to image signal processing chip, one end is connected to high-definition signal processing module, this image signal processing chip and common CRT
Display terminal is connected to.
In specific implementation process, this high-definition signal processing module is made up of integrated circuit, specifically adopts the integrated electricity of PW52 type
Road is constituted.
When television set reception is when being general analogue signal, directly transmit analog signals to image by way selectors
Signal processing chip, is transferred to common CRT display terminal and shows after process, high-definition signal processing module has no effect on this simulation electricity
Depending on the process to general analogue signal for the machine.When there is high-definition signal HDMI port, by HDMI port by this digital high-definition signal
Way selectors are transferred to based on COAX transmission technology, digital high-definition signal is sent to high-definition signal and processes mould by way selectors
Block is processed, and the unification of digital high-definition signal is converted into the YUV signal that image signal processing chip can be processed, high-definition signal is processed
