5. Q&A
Q1: DVI, HDMI, VGA and CV Port Definition.
A:
DVI: Digital (HD) Video Signal, an interface standard jointly introduced by DDWG
(Digital Display Working Group) combined by Silicon Image, Intel and etc. It has been optimized
in speed, resolution, HDCP agreement and so on. Its signal source is often desktop and laptop.
HDMI: High Definition Multimedia Interface, a digital audio/video interface technology. It’s
specialized digital interface and can send audio and video signal at the same time with the quickest
data transmission of 5Gbps. Its signal source is usually camera, laptop and information publication
system.
VGA: Analog Video Signal (Video Graphics Array), a video transmission standard
introduced together by IBM in 1987 with PS/2 at the same time. VGA enjoys high resolution,
rapid display rate, rich color and is widely applied among color displays. Its signal source is often
desktop, laptop, VOD and Matrix.
CV: Composite video signal, also called composite video, which can pack all signals together
and transfer it as a whole. Its signal source is usually camera, DVD, Cable Box, VOD and video
matrix.
Q2: Please give a brief introduction of the connection method of graphics, splicer,
transmitting card, receiving card and LED.
A:
Connect graphics DVI (VGA) output port with splicer DVI-IN(VGA-IN) input---output
splicer DVI-OUT to transmitting card---connect transmitting card with terminal receiving card of
the back screen by network cable---connect receiving card with each screen body with control and
cover whole screen by cascade.
Q3: What is output resolution?
A:
Output resolution is pixel mode output by single port of splicer and the largest control
range of splicer output. Regular resolutions are: 1024*768, 1280*1024, 1600*1200 and
1920*1080, which are set with the same resolution mode of transmitting card.
Q4: What is administrator password set in PC Software.
A:
There is no password and it’s allowed to enter into with just a click.
Q5: What are the reasons for failure of serial connection with the application of serial
splicing processor?
A:
Possible reasons are as follows:
1. Wrong selection of COM port. Just click “Confirm” and re-click “opening serial port” key.
