What is the technology primarily used for video distribution in a multi-room setup?

The technology primarily used for video distribution in a multi-room setup is MoCA (Multimedia over Coax Alliance). MoCA technology allows for the transmission of video, audio, and data over existing coaxial cable infrastructure, which is commonly found in many homes. This is particularly beneficial in multi-room configurations because it enables reliable high-definition video streaming to multiple devices throughout the house without requiring extensive new wiring or the need for additional equipment like repeaters or switches.

MoCA works by effectively creating a high-speed network over coaxial cables, allowing for seamless sharing of video content from devices such as cable boxes or DVRs to various televisions or streaming devices in different rooms. This capability is essential for households with multiple TVs that need to access the same content without lag or degradation in quality.

In contrast, the other options serve different purposes. HDMI is primarily a connection interface for delivering high-definition audio and video between devices and is not specifically designed for multi-room distribution. DVR refers to a device that records and plays back television content but does not address the actual distribution of video among multiple rooms. DVD represents a media format for storing video but does not play a role in the distribution technology needed for a multi-room setup.
