Technical notes / DSD4121 RV

The DSD4121 RV High Definition Satellite Television Decoder - Receiver or 'STU' (Set Top Unit) for short.

A clean compact unit that will fit comfortably in most entertainment units or a caravan for that matter.

Altech DSD4121 RV PVR Ready
Utilising the STi7111 microprocessor for handling video streams, this STU can comfortably handle MPEG2 and MPEG4 demands to support high definition viewing. 

This means extraordinary picture quality particularly when watching a movie or your favourite sport.

Key Features

VAST certified ... for any satellite decoder to legally read and display the VAST television and radio services, all receivers must meet exacting standards as set out by the body governing VAST transmission.


- 8 day Electronic Program Guide ... allowing you to see whats on for more than a week in advance but more so allowing you to highlight a particular program and receive an in depth review similar to what is offered by most printed TV guides that you find in news papers and magazines, (now you know where they get their information!).

- Multiple Video output formats ... allowing you to connect to almost any television.  Most importantly HDMI output is available allowing for true high definition viewing.



- Multiple Audio output formats ... giving you the options of both optical audio output and SPDIF coaxial output for true 5.1 surround sound.  Off course, old fashion stereo output is also available.

- Over the Air Software Downloads ... keeping your equipment up to date.  This is something quite special in that newer versions of the STU's operating software are automatically installed when they become available extending both the use and life of your unit.  This all happens in the background so you may not even be aware that this is happening.


- Subtitles / Closed Captions ... this may not be relevant for many but for those with hearing impediments, this can be a vital feature and is available.
