As the ceaseless promotion of flat TV technology, the interface that its deploy is increasing, the not know what to do when product of consumer preference flat, be like certain and optional interface even " interface of USB, blue tooth " the only standard when elect flat product, so after all what interface is is flat product necessary? The author visited TV of much home flat technically to produce manufacturer to be stationed in orchid the project technology personnel of the orgnaization, be as follows all sorts of interface introductions now:
Necessary interface:
HDMI interface: It is interface of newest video of high-definition number sound, watch high-definition program, fall in HDMI passageway only, ability achieves first-rate result, it is the basic interface that high-definition flat TV must have.
DVI interface: It is the video interface that total number word transmits, can not add digital signal changeover ground to be transmitted directly in monitor, compare with HDMI photograph, can transmit video signal only.
Interface of off color heft: It is current in all sorts of video output interface a better kind. Compare the AV in the past and S terminal, off color is signal cent is planted for red, green, La San base color will input, picture qualitative respect is ambitious cross S terminal.
AV interface: AV interface realized the depart of frequency and video to transmit, because,avoided sound / the picture quality that video mixes interference and brings about drops, but because the transmission of AV interface remains a kind of brightness / signal of video of compound of of chroma Y/C, affect the picture quality that outputs finally thereby.
RF inputs interface:
Practical interface:
Fiber-optic interface: It is to be used extensively in result put enharmonic noisy equipment, the flat TV that uses this kind of interface has been illogical result it is OK to put go to frequency join directly on sound box, it is at present the most advanced frequency outputs interface.
RS-232 interface: It is one of communication interface on the computer, use at modem, printer or the peripheral equipment join such as the mouse. The TV that takes this interface can pass this interface to undertake safeguard and upgrading to the software of TV interior.
