Video distribution refers to the process of transmitting audio and video signals to different destinations within a home, facility or organisation. This is commonly used in settings such as homes, offices, educational institutions, conference centres, retail spaces, and more. The goal is to share consistent and synchronised AV content across various displays or audio systems throughout the venue. In a residential application, the video distribution allows the video sources such as TV boxes or players to be centrally located and be distributed throughout the house to various displays.
Centralised Source
There is a central location or source where the audio and video content originates. This could be a media server, a presentation system, a TV box like Foxtel or Apple TV, a broadcast studio, or any other device capable of generating AV signals.
Distribution Equipment
This includes devices such as matrix switchers, distribution amplifiers, and video extenders. Matrix switchers allow users to route specific sources to specific destinations, ensuring flexibility and control over the distribution. Distribution amplifiers replicate and boost signals to maintain signal quality over longer cable runs, while video extenders transmit AV signals over longer distances.
Cabling Infrastructure
High-quality cabling, such as CAT6A is essential for transmitting AV signals between the central source and the various destination points. The type of cabling used depends on the specific requirements of the distribution system.
Destination Points
These are the areas or zones where the AV content is intended to be displayed or heard. Each destination point may have its own display screen, projector, audio system, or a combination of these components.
Control System
A control system is often implemented to manage and coordinate the distribution of AV signals. This could involve a control panel, touchscreens, or software interfaces that allow users to select sources, control volume, and manage other aspects of the AV system.
Scalability
Video distribution systems should be scalable to accommodate the expansion or modification of the AV setup. This is particularly important in large facilities where the number of destination points may change over time.
Signal Quality and Synchronisation
Maintaining high-quality AV signals and ensuring synchronisation between audio and video is crucial to delivering a seamless and immersive experience. This involves using appropriate equipment and ensuring that signal delays are minimised.
AV distribution is the process of transmitting and delivering audio and video content from a source to one or more destinations.
HDBaseT (High-Definition Base-T) is a connectivity technology that allows the transmission of high-definition audio and video, Ethernet, controls, USB and up to 100W of power over a single cable, for up to 100 m/328ft.
Share AV sources
Use the same source in multiple areas
Locate your AV sources centrally in a different location like a comms room
Less hardware and boxes inside the room
One cable carries AV, control signal and internet
In a commercial application like a university you can broadcast content from a central location
HDBaseT (High-Definition Base-T) is a connectivity technology that allows the transmission of high-definition audio and video, Ethernet, controls, USB and up to 100W of power over a single CAT cable for up to 100 m. HDBaseT eliminates cable clutter without compromising performance and high quality.
AV over IP (Audio-Visual over Internet Protocol) refers to a technology and methodology that allows the distribution of audio and video signals over standard IP networks. Instead of using dedicated CAT cables, AV over IP leverages the existing data network infrastructure to transmit audio and video content to multiple endpoints, such as displays, projectors, or speakers.
