What Exactly Is A Network Video Distribution System?

The distribution of video, more precisely media distribution systems, are a crucial component of any large or medium-sized institution or holding. They provide information, entertainment, as well as security to institutions that serve large populations with different requirements.

In describing and delving into audio visual systems, we can dive into serious details, as well as pertinent. In this article, however we’ll try to grasp the essential components of the system and, generally speaking the way they work.

Easy Solutions, Limitations and Simple Solution

The fundamental definition of a network video distribution system typically can be described as the ability to deliver media from a source to a display or multiple screens, also known as sinks.

The most basic video distribution system is one source of video like an cable TV box, which is then distributed to multiple video sinks through a passive splitter. An example of this would be the sporting bar where a bar includes a range of video monitors that can be supplied with by the exact same sports event.

Although the splitter setup is able to work with analog systems with ease and low maintenance, however, it is not ideal for running cables of any length. The distances are based on a variety of variables, such as signal type and the quality of the cable. The issue is that without assistance or processing, an electrical signal is eventually subject to the effects of the wire and start to weaken the signal.

To show the effect that the length of cable can have on video signals, think of the video signal coming that comes from the cable box like a sequence of square waves, each with distinct edges. As the signal continues to travel along the cable, the inherent resistance starts to smooth out areas of signal. This makes the edges less distinct, and the signal is smaller in size. This results in an image that is much smaller and less clear in comparison to the first.

To counteract this loss of signals, several intermediary boxes may be included. They are placed within the line to amplify signals at different locations within the topology. These boxes could comprise power (or actively) splitters amplifiers, inline amplifiers, and monitor units. end.

A second of thought will show that any installation of a larger size will require a significant amount of equipment, cable management and the challenges to ensure that all monitors are identical.

More than Video

The above example is an easy method of demonstrating the fundamental structure and potential pitfalls that can arise from an old-fashioned video distribution method the most modern systems are much more efficient in moving video.

As mentioned at the beginning in this piece, the networks are often referred to as media distribution networks. They also offer video. networks also provide streaming content as well as libraries that are on demand and ethernet/internet data, digital signage messages and emergency alerts.

If we take the previous example and assuming that the network is a good fit, it is reasonable to assume there is a rise in the amount of goods to be distributed through the network will result in an increase in cable and hardware as well as the complexity.

The current version of distribution networks could be described as more complex and simple.

Current cable vs. New cable

It may be odd initially, starting with the cable, but its topology is the basis for the requirements of the of the system as well as how it functions.

In lieu of solid copper such as the coax cable used found in sports bars the most popular cable is a category cable that is twisted. The CAT cable has many advantages over the previous standard cables. It has a greater bend ratio, greater flexibility when it comes to getting around corners, and a tighter conduits, as well as better tools to deal with signal loss and error. Connectivity is also advantageous since almost everyone in IT and technology knows how to terminate the RJ45 that is used.

Most likely, you’ve assumed that you are seeing or shouting out ‘CAT 5 cable’ while reading the information above. While many manufacturers claim compatibility with wiring systems that are already in use, there are a few caveats to making such claims.

The CAT 5 cable, due to its loose twists per inch , and being an UTP (Unshielded Twisted Pair) It is not constructed to support for a significant length of the bandwidth and throughput speed required. An in-depth understanding of the specifications of the manufacturer and their limitations when using CAT5 or CAT6e is crucial.

It is possible to set up a well-known Twisted Pair distribution system using the existing cables. In most cases, this will lead to shorter lengths, or the requirement for more booster boxes in order to provide an equivalent coverage.

To ensure high reliability future proofing, as well as less requirement for compression and processing, it is recommended to replace CAT 5 with CAT6e for distribution of media.

Matrix (More of the to more of those)

It is unlikely that any university or corporate offices would require just the capability of sending one source to a series of dispersed monitors constantly. With the many sources of content available, we require an efficient method of routing the content to all, one or a specific amount of sinks.

The matrix offers us the capability to gather the various formats and sources and distribute them to the places they are requested or requested. All this has to be done without disrupting viewers who are watching other programming on the same channel.

Any matrix is expected to be able to manage the switching between sources regardless of the formats switching between them, with no artifacts. It may seem like a minor aspect to be focusing on however, it’s a crucial aspect. When a system is used over the long haul, an array that produces artifacts, glitches, or flashes in between sources can be a nuisance for users, distracting viewers, and appears less professional.

Matrix boxes are available in two different configurations.

First, there is the closed-chassis in which the quantity and type of connections are specified and the shell is sealed. The products that are constructed this way ensure an operation that is of high quality for a particular purpose and limit the entry of dust and hand-holds.

The second one is the model for a cage. It is where installers are able to create cards using the right configuration of connectors, and then process according to the requirements of the job. Card cages are generally slightly more costly initially but the possibility to upgrade or replace cards whenever needed can save the cost of buying an entire new unit or devices.

Receiver Boxes

Once the signal arrives at the monitor that is intended for it or, in the case of electrical signals”the sink, it has to be transformed to a compressed version (if it is compressed) and also the type of signal. The majority of video monitors don’t have a CAT 5 input since the variety of standards is simply too large to be able to handle all of them.

Receiver boxes are typically placed in a wall-mounted electrical box, which is located behind the monitor for video, or, more often, to on the side of the device. Twisted pair cables arrives in one end and is processed until it is broken out, corrected for errors and amplified according to match the required signal format.

The boxes at the sink end ensure that the received signal is at its best and minimizes the requirement for intermediate signals amplifiers or booster boxes. This easy, yet effective method improves reliability and lowers the costs of the entire system.

The basic concepts of the media distribution system are easy enough to comprehend. Understanding the process of designing and installing the system takes a little more research. It is recommended to study the technical manuals of products of companies both big and small, using the information in this post as your guide.
