Recently, the most big
issue in CCTV market must be the expansion of Full - HD (High Definition)
system. The change of resolution from the existing SD (Standard - Definition)
class (720x480 in case of NTSC) to Full HD (1920x1080, 1080p) requires the
whole system change, not only the video quality enhancement of camera simply.
Because the conventional SD - CCTV (NTSC/PAL) is based on analog TV standard, it
could not meet the market request for the high - resolution, clearer video
image in digital era of HD TV. The first step for high resolution was started
from Megapixel IP camera adopting HD class image sensor, and recently HD - SDI
transmission technology which have been used for digital video transmission
between broadcasting equipment was grafted into CCTV market , and introduced as
the name of HD - CCTV system.
