What is an AV Distribution System?
An audio/video (AV) distribution system is a network of components that allows you to distribute audio and video content throughout your home. An AV distribution system includes video sources like cable/satellite boxes, streaming media players, Blu-ray players, game consoles etc. It also includes displays like TVs, projectors and audio equipment like speakers.

The main components of an AV distribution system include:

Sources - Devices that output audio and video like cable boxes, streaming media players etc.

Distribution Equipment - Components like AV receivers, matrix switches, audio/video splitters and extenders that receive signals from sources and distribute them to displays and speakers.

Displays - Televisions, projectors or any other device that receives and displays video signals.

Speakers - Loudspeakers that receive and play audio signals from sources.

With an AV distribution system, you can watch or listen to the same content in multiple rooms simultaneously. It allows for centralized control of sources from different areas of the home.

Types of AV Distribution Systems
There are different types of AV distribution systems depending on your home, budget and needs:

Whole Home Audio
A whole home audio system focuses only on distributing audio to different speakers around the home. Audio components like a receiver and speakers are placed in multiple rooms and zones. This allows listening to the same music in every room.

Basic Room-to-Room Distribution
A basic setup involves distributing an AV source like a cable box to just 2-3 rooms. Components include splitters, baluns and extenders to transmit HDMI and optical audio signals over coax or CAT5/6 cables between rooms.

Full-fledged Multi-Room System
More advanced setups distribute multiple sources around the entire home. They utilize networking equipment, modular distribution boxes, app-based controls and more zones/speakers. Each TV and room has its own dedicated inputs and volume/source controls.

Outdoors Entertainment System
For integrating outdoor speakers, this type of system extends AV distribution outdoors. It is great for pool areas, patios and backyard movie nights. Waterproof speakers and amplifiers are used.

Components of an AV Distribution System
Now let's take a closer look at some of the key components that make up an AV distribution system:

Sources
As mentioned earlier, sources are the audio/video generating devices like cable/satellite boxes, Blu-ray/DVD players, streaming devices, gaming consoles etc. Multiple sources can be integrated.

AV Receiver
The AV receiver is essentially the control hub or 'brain' that receives and processes signals from sources. It splits and distributes these signals to displays and amplifies audio for speakers around the home. Higher-end AV receivers support more advanced distribution functions.

Matrix Switch / Multi-Zone Controller
A matrix switch or multi-zone controller takes the place of a standard AV receiver for larger whole home systems. It provides additional zone outputs, simultaneous distribution to multiple rooms and app/remote controls.

Cables and Connections
Different cables like HDMI, optical, 3.5mm, coaxial etc are used depending on the distance between components and types of signals being distributed (video, audio or both). Baluns may be required to convert between cable types.

Equipment for Whole Home Audio
For distributing multi-channel audio, devices like standalone networked music streamers, multi-zone amplifiers, networking switches and additional speakers are required in each room or zone.

Wireless Distribution
While wired is preferable for reliability, wireless HDMI systems, networked streamers and Bluetooth/WiFi speakers provide cable-free flexibility for some applications. However, wired is still favored for whole home setups.

Planning and Installing an AV Distribution System
Proper planning is essential before installing any home AV distribution system. Here are the key steps:

Assess Needs and Budget
Take inventory of rooms/devices requiring distribution. Determine distribution points and how many simultaneous streams are needed. Set a budget based on number of TVs/speakers and types of sources used.

Draw a Home Layout Map
Draw out the floor plan and map out equipment locations, source locations, cable routes between rooms, power outlet locations etc. This helps visualize the setup.

Choose Distribution Equipment
Select an AV receiver/controller, splitters, baluns, switches based on the map and necessary simultaneous video/audio streams needed in each room.

Run Wires and Cables
Run all necessary HDMI, audio, Ethernet and power cables throughout the house to each distribution point before drywalling/construction. Consider future expandability.

Connect and Set Up Sources
Once wiring is complete, connect sources to the receiver/controller and run through initial setup processes like input naming, room configuration, WiFi setup etc.

Calibrate Audio Levels
Balance volumes in each room and between rooms using test tones and SPL meters. Adjust EQ, Crossovers and delays according to room acoustics.

Program Remote Controls
Customize universal remotes or app controls for ease of use by others in the home for basic source/volume operations. Add optional automation integrations.

Proper planning is key to getting the most out of any home AV distribution system investment for years to come. With the right components and installation, the whole family can enjoy easy access to all their entertainment throughout the house.
