Ever since Thomas Alva Edison made an experimental movie, videos came into being with movies being their most common and renowned implementation. Earlier, the videos used to be a state of the art, analog based technology.Soon came the digital video, implemented in the early 1990s. The videos had progressive interlacing and better definition.With the advancements in video technology, the world saw: digitized video: interactive video, real time video, streaming video. The real time video, and the streaming of videos to video a distribution infrastructure, all this is a part of AV over IP. The transmission of audio/visual data over a network such as LAN, WAN or Internet by making use of standard network equipment is called AV over IP.
DIFFERENCE BETWEEN CONVENTIONAL AV AND AV OVER IP:
The purpose of conventional A/V systems was the extension and switching of audio and video data. To be able to let users see and hear on the video and audio system, the source needs to be captured, moved, switched and displayed. An AV over IP infrastructure is a steaming infrastructure. In AV over IP, you have encoders, decoders and an IP switch just like a traditional AV setup has a transmitter, receiver and video switch.
The difference between a conventional AV and AV over IP is the facility of expandable switching. In the hardwired circuit based switching the transmission techniques used, was point to point. But with video over IP, the number of ports can be expanded almost indefinitely, depending on the network bandwidth. Since ,there are no limited number of sources attached to the IP switch, you can have as many as inputs and as many as outputs as the network allows.
AV over IP makes use of standards to for transmission on IP networks and compatibility with the IP switches. This facilitates interoperability between products from different vendors.
With the help of packet-based switching technology, the complication of distance as well as the limited number of sources is fixed.
BENEFIT OF AV OVER IP
Now with the help of AV over IP, audios and videos can be created, processed, compressed, and sent over any network circuit, following are the benefits of video over ip:
The AV over IP network has layers that provide enhanced command and control security with password permissions. The content can also be encrypted to prevent any unsanctioned access.
With AV over IP, the quality of the output be it an audio or a video is significantly improved.
Latency is a major issue in the digital signage. The issue of time lapse between audio and the displayed video is reduced by the compression algorithm used in high end AV over IP.
AV over IP can be easily installed in your existing network so the cost of separate cabling gets eliminated. Since the content can be dynamically altered remotely, there is no requirement for any party to physically move and change signage.
With the demand for more and more real time, AV over IP provides the much desired benefit of good quality video content , that can be customized remotely and has an easy installation process.
