Q1: DVI, HDMI, VGA and CV Port Definition.
A:
DVI:
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 normally desktop or 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 or 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 normally 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 normally 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
