The DirecTV Ethernet Coaxial Adapter (DECA) is a upcoming technology DirecTV is developing to aid in networking receivers. The DECA networking operates at similiar speeds to a traditional wired network and provides better speeds than commonly used wireless or powerline networking.
This enables another method of networking DirecTV receivers to enable key features including On Demand, DirecTV2PC, MediaShare, and Multi-Room Viewing (future feature in development). The DECA connects to H21, H23, and all HR2x receivers (no word on R22 yet).
The DECA requires a SWM environment. It will not work with traditional LNBs / switches. It will work with the SWM LNB or external switch. If using an external SWM switch, all DECA adapters must be fed off the same port.
DECA operates using bandwith from the SWM setup, and therefore prevents the ability to diplex OTA signals into the configuration. DECA uses the same bandwith a diplexer would use for OTA, the 500-600mhz range.
HR20-100 receivers have a special need of connecting to both satellite inputs on the receiver for additional power, despite using an SWM configuration. Only one connection to the SWM is required though. The HR20-100 simply doesn't put enough power out of one receiver connection to power DECA properly (although that could change in the future).
This is a networking setup that requires some additional parts. There is a DECA Coax adapter (picture attached) that is essentially the network interface adapter.
There is a SWM filter that blocks the 500-600mhz range to prepare for DECA signals. This filter is placed at the output of the SWM before any splitters.
There is a power inserter required that operates at 21 volts, and is very similiar to the existing 29 volt SWM power inserter. In a setup with SWM and DECA, a user would need two power inserters.
Lastly, there is a splitter used at a receiver to integrate the internet connection.
Here is a basic diagram of how DECA would work:
SWM LNB on dish outside --------> SWM Power Inserter ---------->DECA Filter---------->SWM Splitter (2, 4, or 8 port splitter up to 2300mhz)
From the SWM Splitter ----------> DECA Adapaters --------------> Receivers
except the room with an internet connection:
From the SWM Splitter ---------> Supplied DECA Splitter -----------> DECA Adapter ------> Receiver
From the SWM Splitter ---------> Supplied DECA Splitter -----------> DECA Adapter ------> Internet Connection
Networking two receivers would require three DECA Adapters.
Networking three receivers would require four DECA Adapters.
All configurations require one DECA filter, one DECA 21v power supply, and one DECA splitter. All configurations require SWM.
Tests have indicated sppeds comparable with traditional wired networks and the ability to playback HD content (including 1080p) without video breakups and flawless audio.
No word on price, availability, or timeline, as this product is still in development.
