Case Study 2: 4K Residential AV Distribution Network
A privately owned home needs a retrofit 4K video distribution system. Sources are
located in the basement rack room and are distributed to TV and surround sound
receiver locations throughout the house. The desired system requires two satellite
receivers, two cable set-top boxes (STBs), two streaming boxes, and one disc player.
The media room and family living room require surround sound systems with a local
4K HDR Blu-ray™ player and 4K HDR displays. All other rooms require external speakers
with stereo output. The kitchen, master bedroom, and master bathroom require
in-ceiling speakers. Touch screens are the desired control surfaces. The media room and
family living room are not able to have wire runs for the touch screens—only local power
is available. Existing network infrastructure can be reused.
Solution:
• The Crestron design is based on the use of DM-NVX-350C cards as encoders,
DM-NVX-351 surface-mountable endpoints as decoders, and the
DM-NVX-DIR-80:
- Seven DM-NVX-350C cards are installed in a DMF-CI-8 chassis in the
basement rack. Each of the seven video sources in the basement rack room
connects to a DM-NVX-350C encoder.
- The kitchen, master bedroom, and master bathroom each have a
DM-NVX-351 decoder that connects to a display and provides audio
downmixing. The stereo line audio output of a DM-NVX-351 connects to a
two-channel amplifier with two Crestron Saros® IC4T in-ceiling speakers per
room.
- Bedrooms 1, 2, and 3 each have a DM-NVX-351 decoder that connects to a
display and provides audio downmixing. The stereo line audio output of a
DM-NVX-351 connects to a Crestron Saros SB-200-P sound bar.
- The media room and family room each include a surround sound system that
connects to a DM-NVX-351. The HDMI OUT from a surround sound system
connects to a display. In-room speakers connect to the surround sound
system.
- A DM-NVX-DIR-80 is used to set up, control, and monitor the DM NVX
system.
• The kitchen and three bedrooms each use a TSW-760 touch screen. The rooms
can also be controlled using the Crestron App for mobile and tablet devices.
• Due to a cable routing constraint, the media room and family room each have a
TST-902 wireless touch screen for control. The rooms can also be controlled using
the Crestron App for mobile and tablet devices.
• A Crestron PRO3 control processor with expansion cards controls the entire
system by providing IR and other peripheral control.
