Multi-Room Video System
Multi-Room video system – is a video distribution on the premises. In fact, it’s the same thing as multi-room audio, however here we have to distribute not only the audio but both image and sound. Implementation of multi-room video is slightly more complicated and more expensive, but it allows the owner to control the system the same way as the audio multi-room and enjoy movies and tv-content in all designated areas.
As with the multi-room audio systems, video distribution networks can be centralized or local:
The centralized system usually is designed and installed during new home constructions or home repair projects. This is done mainly because it is rather complicated (although certainly not impossible) to supply a cabled video distribution network in the finished home.
As the name implies, all video sources, switches, and control systems are installed in one place, as a rule, in a special rack.
TVs and projectors in the designated rooms are connected either by HDMI cables, or (when the distance is significant) by network cables and signal converters on the receiving end.
If you want a better surround sound (such as 5.1, 7,1, Atmos or DTS:X), you will need to install it in a corresponding room. Speaker system is then connected to either a local amplifier or, via speaker cables, to the main unit in a rack.
All control is performed with a choice of several units such as touchscreen panels, portable consoles and mobile devices (tablets, smartphone etc).
This kind of system architecture is ideal in its design and structure and also very flexible for any future upgrades.
Local system involves the installation of media players on directly in the zones (rooms, outdoor areas etc), which are connected to a centralized source of content. There is a server with audio and video content from which media players in the rooms receive signal. In case you would want a better sound quality, you will need to insure that there is an AV receiver with a speaker set in a corresponding room.
The main difference between a centralized and a local multi-room video system is that at in a centralized design, all sources and all the players are concentrated in one place, and then using matrix switches are distributed to a different rooms via cables. In a local structure, there is usually one centralized source, but no central distribution or playback option. Basically, this is a more affordable and easy to install system, although it has many limitations.
