There are various forms of displays and sign boards installed in public places. An electronic form of display used in various places is known as digital signage. They have various intensions to be installed in public area. These are normally used for passing information or for advertising purposes. They can also be used for entertainment purposes as well. The main advantage of these displays which helped them to replace the traditional sign boards effectively is the easiness in changing the content of the display.
Another advancement seen with the growth of technology is the use of video over IP. They use some standard video codec for reducing the material to the size of a bit stream. IP network is largely used to carry the bit stream, by encapsulating them in various packets.
Carrying IP video as packets has more challenges than the most of the non-time-critical traffic. This often comes in need of a higher level of engineering requirements. The delay in network could be minimised with the help of a proper network backbone. This ensures that the video traffic never faces any delays in the queue. Adequate bandwidth could be used to ensure that, there are no overloads in the network.
