Crystal Vision Introduction
1 Introduction
The Up-Down 3G is a range of nine up-down converters that allow flexible up, down and
cross conversions between 3Gb/s, HD and SD sources, provide an output picture of
exceptional quality and include special features to allow studios to easily operate in HD and
SD at the same time.
The Up-Down 3G range consists of the following models: Up-Down 3G, Up-Down-A 3G, Up-
Down-AS 3G, Up-Down-AFD 3G, Up-Down-AFDS 3G, Up-Down-AT 3G, Up-Down-ATS
3G, Up-Down-ATX 3G and Up-Down-ATXS 3G.
The up conversions are SD to 720p, 1080i or 1080p. The cross conversions are 720p to
1080i or 1080p, 1080i to 720p or 1080p, and 1080p to 1080i or 720p. The down conversions
are 1080p, 1080i or 720p to SD. Up-Down 3G’s excellent picture quality is a result of motion
adaptive video de-interlacing, which maximises the picture’s vertical resolution while choosing
the best processing method based on the video content.
Up-Down 3G can perform two conversions at the same time, with two separate converters on
the board: one is used for the up and cross conversion, with the other used for the down
conversion, which makes it the perfect up/down/cross converter for installations that work in
multiple definitions, allowing simultaneously HD and SD copies of a feed from one board.
Up-Down 3G provides two feeds of the main output and three feeds of the secondary output.
The most common application is to have HD (720p, 1080i or 1080p) on one output and SD on
the other, and the input as either SD or the same HD as the output. Up-Down 3G is useful for
installations that work in both HD and SD because it allows them to easily create HD and SD
copies of a feed and so fulfil their requirement to offer HD and SD programming
simultaneously.
One of Up-Down 3G’s particularly powerful features is that it will always put out HD and SD in
the same place on the same pins, regardless of the input – meaning you always know which
output is going to be which and therefore don’t need to change your wiring. Each output will
either be converted from the input or be given a matching delay as required, with the
matching delay allowing all the signals to have the same timing and enabling the use of
common audio. Should you need an additional six input loop-throughs, a DA6 top board can
be added. Up-Down 3G can easily include integrated fibre connectivity by fitting the
appropriate fibre input or output option.
Noise reduction with detail and edge enhancement can be applied when up converting, cross
converting or down converting from 3G to 1.5G. Separate RGB and YUV proc-amps give lift
and gain controls to look after your picture colour fidelity and faulty video signal problems
provide warnings using SNMP traps. Status indications available (depending on model) are
video not present, video frozen, video black and both audio not present and audio silent on all
four groups.
Up-Down 3G will look after any aspect ratio conversion requirements when up or down
converting. All versions can be used as an SD to SD aspect ratio converter if required. Up-
Down 3G models AT / ATX / ATS / ATXS can be used as an HD to HD aspect ratio converter
for when the HD input and output formats are identical. This can be useful to correct the
aspect ratio of signals that were up converted using the wrong aspect ratio, resulting in an HD
image that is too squashed, stretched or cropped.
Up-Down 3G models AFD / AT / ATX / AFDS / ATS / ATXS additionally offer AFD code
activated aspect ratio conversion.

Crystal Vision Introduction
Up-Down 3G is a space-saving 100mm x 266mm module which fits in the standard Crystal
Vision frames, with the inputs and outputs accessed by using either the RM41 or RM57 frame
rear modules. Control options include an active front panel on the frame, a remote control
panel, SNMP and the VisionWeb PC software. Board edge control was also available prior to
2019.

• Transport and convert CEA-608 and CEA-708 closed caption data between standards.
• Carry teletext and subtitle information across different definitions - both SMPTE 2031 and
OP-47 supported.
The Up-Down-ATX 3G supports SMPTE 2031 and OP-47 to carry teletext information across
different definitions. When up converting teletext data can be taken out of the analogue coded
signal and the same data put in the SMPTE 2031 or OP-47 data stream created; when down
converting the teletext data can be taken out of SMPTE 2031 or OP-47 packets and be
encoded as analogue waveforms on an SD output. Up-Down-ATX 3G can be used to convert
between SMPTE 2031, OP-47 and teletext in any combination. It is also possible to specify
which line in the VANC space is used to carry SMPTE 2031 or OP-47, an advantage given
the increasingly crowded VANC space. Closed captions can also be transported across
different definitions using its CEA-708 and CEA-608 extractors and inserters.

conversion. This allows simultaneous creation of HD and SD copies from a single feed from
this one board.
Up-Down 3G gives dual outputs, with two output groups – A and B. Each output group can be
individually selected as either SD or HD (see Output Formats and Timing), making it possible
to configure both outputs as SD, both outputs as HD (720p, 1080i or 1080p), or one output as
HD with the other as SD.
One of Up-Down 3G’s most powerful features is that it will constantly put out HD and SD on
the same pins regardless of the input, thanks to its smart routing. Once set, the output
selection will remain true irrespective of any change in the input format – which means wiring
can remain unchanged.
Up-Down 3G will automatically select the correct conversion algorithm depending on the input
format and selected output formats.
