Video communication is prevalent across industries for a couple of decades since globalization, as more and more businesses have offices or clients across the globe. This is one effective way of communication, which has gained even more traction from the last year since the pandemic. With strict restrictions and regulations imposed on human mobility, everything from business summits to formal project meetings to e-learning and recruitment now mostly relies on video conferencing. There is no secret that video files are large as well as bandwidth-intensive. The increasing demand to stream both live and on-demand videos can have a significant impact on the network performance as well as user experience. Seamless delivery of videos over the network requires a combination of sophisticated technologies, and this is where a video distribution system make a significant difference. The distributed video systems transmit uncompressed, unencrypted video signals to multiple outputs. By doing so, they reduce the overall wiring complexity and distribute the video content as required. This post discusses the video distribution system in detail. So, stay tuned.
A Quick Overview of Video Distribution System
A video distribution amplifiers or media distribution system is a network that comprises video sources and display devices. These networking devices are interconnected using structured wiring and a centralized system. Once the connection has been made, the system allows the output signals from video sources such as personal video recorder (PVR), video cassette recorder, or any other video device to be viewed on the systems connected within the network.
Detail Discussion on Designing a Distributed Video System
Designing a distributed video system demands a systematic approach intended to identify individual objectives, cabling, and controls required to achieve specific goals. The following are some important steps involved in the designing of a distributed video system.
- Identification of the Distribution Points: Be it residential or corporate environment, identifying the distribution points is one important aspect. Let’s take an example of a simple multi-room video distribution system. The homeowner will decide whether or not any room in a house is wired into a distributed video system. In a structured wiring environment, the selection of distribution points depends on the placement of the video system. Areas that share common video signals belong to the same video zone. Each room is potentially a separate zone when it has its source device. Whether to support single or multiple zones in the distributed system is a key decision that should be made during the early phase of the design.
- Evaluation of the Layout: Evaluating the layout of a particular area is another important consideration. This depends on several factors such as placement of the control system, the termination point of the video cable, types of extenders installed, and much more. In many scenarios, these things are considered during the structured wiring planning. It’s always best to place the video connection near to the video display sources. For instance, the video connector should be placed on the wall or close to the television that is to be connected to the distribution system.
- Decision on Control Systems: Next, it is important to decide on the control system installed in each zone. If all zones receive the same video signal, then only on/off and volume controls are required for each room. The on/off function can be controlled using a local handheld device, allowing audio and local control of the display device. If an individual wants to control a centralized source from a zone, then a multi-function controller is used. It is an all-in-one handheld remote programmed to control multiple source devices.
- Centralization of the Source Equipment: Whether it is a new connection or remodeling the existing one, where it’s pretty easy to run cables from the individual zone back to the centralized equipment, dedicated and direct wires are used for signal transmission. The list includes co-axial cable, HDMI, and much more. RF or IR signals can be converted by a built-in zone receiver and transmitted through wires to the centralized equipment. Choose the location of the centralized equipment in such a way that all cables from different zones should terminate there.
Benefits of Distributed Video Systems Analyzed
The following are some important benefits of video distribution systems:
- As the name implies, you can share a single video source among multiple devices. This results in minimizing the number of sources required for televisions in the house.
- It is possible to hide all the gear of televisions using the distributed system.
- In this, an HDMI switch with HDBaseT technology is used to distribute videos throughout the zone. The switch has ports wherein all the components get plugged in easily. This means, in one storage closet you can have cables, media players, gaming consoles, or anything you would like to watch on the television.
- In the distribution system, an IR repeater is used to control all hidden equipment.
