<P> Digital Visual Interface (DVI) </P> <Li> <P> HDMI </P> </Li> <Li> <P> DisplayPort </P> </Li> <P> Video can be transmitted or transported in a variety of ways . Wireless broadcast as an analog or digital signal . Coaxial cable in a closed circuit system can be sent as analog interlaced 1 volt peak to peak with a maximum horizontal line resolution up to 480 . Broadcast or studio cameras use a single or dual coaxial cable system using a progressive scan format known as SDI serial digital interface and HD - SDI for High Definition video . The distances of transmission are somewhat limited depending on the manufacturer the format may be proprietary . SDI has a negligible lag and is uncompressed . There are initiatives to use the SDI standards in closed circuit surveillance systems, for Higher Definition images, over longer distances on coax or twisted pair cable . Due to the nature of the higher bandwidth needed, the distance the signal can be effectively sent is a half to a third of what the older interlaced analog systems supported . </P>
