Crystal Vision Introduction

ADDEC-310 User Manual R1.2 310/12/2007

1Introduction

ADDEC-310 is a broadcast decoder. It brings together onto one PCB both the functions

of a 12-bit broadcast decoder and synchroniser/delay module.

The ADDEC-310 will convert PAL/NTSC composite, Y/C or YUV/RGB component

video to SDI using a high quality 12-bit decoder which can deal with any source from

broadcast quality to VHS, and will accept damaged or jittery signals. The data is sampled

at 54 Mbit per second (four times oversampled) allowing the highest quality digital

filtering. It also offers the latest in comb technology, with a five-line comb resulting in

exceptional decoding. Timing, gains and levels are also adjustable.

The on-board video frame synchroniser allows untimed inputs to be timed to the local

syncs. It will sort out any incorrect frame rates plus any delays by taking its timing from

the external analogue reference and will automatically synchronise sources between 0 and

2 fields.

An audio follow pulse is also produced which allows ADDEC-310 to be used with an

external audio delay such as the TAD202

The ADDEC-310 will fully integrate with any other interface or keying product from the

Crystal Vision range. Further flexibility is afforded by the large choice of control options,

which include board edge control, local or remote active control panel and the Statesman

PC Control System.

The main features are as follows:

•12-bit digital decoder

•Suitable for all sources, from broadcast quality to VHS

•High quality digital filtering and 5-line comb

•Frame or line synchroniser or used as a fixed delay times input to local reference

syncs

•Flexible control, including PC software.

•Up to four Serial Digital outputs.

•Internal proc amp

•Audio follow pulse output

•Compact design for high packing density

•Full range of inter-changeable rear connector modules

Crystal Vision Introduction

ADDEC-310 User Manual R1.2 410/12/2007

ADDEC-310 12-bit Synchronising Decoder

The ADDEC-310 is a 100mm x 266mm module that fits in Crystal Vision’s four standard

frame sizes. 24 modules fit in 4U, 12 modules fit in 2U, six in 1U or two in a desktop box.

There are a range of rear connector modules available for the ADDEC-310 which offer

the system builder great flexibility in frame configuration.

1.1 Operating modes

Synchroniser and Delay Modes

There are two modes of operation, Synchronisation and Delay.

In Synchronisation Mode the unit takes its timing from the analogue external reference

and will automatically synchronise sources between zero and two fields. Synchronisation

Mode is ideal for external sources that are not timed to station references such as satellite

or remote contribution feeds.

In Delay Mode, timing is derived only from the analogue input. Typical applications are

where a source passes through a processor such as a DVE, Chroma keyer or standards

converter where the delay can be a few microseconds, multiple lines or up to two fields.

Crystal Vision Introduction

ADDEC-310 User Manual R1.2 510/12/2007

The video delay remains fully adjustable over two complete fields. This allows the output

of the ADDEC-310 in synchronisation mode to be timed into any edit suite irrespective of

the timing of the black and burst reference used.

Audio follow pulse

There is also a positive going external TTL level audio follow video (AFV) pulse output,

the duration of which reflects the current video delay. The AFV output can be used with

external audio delay processors such as the TAD202 if required.

Analogue video formats

The analogue video input can be selected to be composite PAL/NTSC and YC or

525/625-line component YUV/RGB. ADDEC-310 can accept an RGB input with sync

pulses on either all three components or Green alone. There is also an RGB external sync

input should the RGB video not have syncs present. Input standard selection is automatic

and will follow the input video. Data in the VBI (vertical blanking interval) of the

analogue composite input can be blanked or passed. NTSC- J and NTSC-M with or

without 7.5% IRE set up is also selectable when receiving an NTSC format video input.

Betacam input levels are also accepted.

Freezing the picture

The picture can be frozen and the freeze mode can be selected from freeze frame, field 1

and field 2. In situations where there is movement between fields a frame freeze may

show movement judder. To prevent this, a field freeze which works by repeating the same

field will produce a synthetic frame of video without movement judder. However a field

freeze is more likely to show jagged edges on near horizontal lines.

Video Input loss behaviour

The ADDEC-310 output will cut to blue immediately on loss of input video.

Status and control

Status and control of the ADDEC-310 is available using the board edge menu selection

switches and 10-digit display. Full function control and status reporting is also available

from either an active frame front or remote active control panel. PC control is also

available using Crystal Visions Statesman PC controller package.

Crystal Vision Hardware installation

ADDEC-310 User Manual R1.2 610/12/2007

2Hardware installation

The ADDEC-310 single height module uses the RM01, RM23, RM24, RM25 and RM27

rear connectors. The RM25 quad height module will only fit into the 2U and 4U frames,

although the rest will fit into all Crystal Vision rack frames. All modules can be plugged

in and removed while the frame is powered without damage.

2.1 Rear modules and signal I/O

The Indigo 4 4U frame will house up to 24 single height modules with up to three power

supplies. The Indigo 2 2U frames will house up to 12 single height modules and dual

power supplies. The Indigo 1 1U frames will house six single height modules and a single

or dual power supply. The Indigo desk top boxes both have a built-in power supply and

will house up to two single height modules.

Note: For details of fitting rear connectors please refer to the appropriate frame manual

Rear module connections with RM01

The RM01being a single height module will allow maximum packing density with the

maximum number of outputs available.

Module configuration

The ADDEC-310 has eight user selectable jumper links, which configure the Component

U / YC-C / Serial digital output, the Component V / SDI OUT, the RGB / SDI OUT and

the RGB sync input and the external reference input termination impedance.

There are also three preset potentiometers. These are factory set and should not require

any adjustment.

Note: Not all input/output combinations are available with all rear modules.

ADDEC-310 moveable links

V/R / SDI OUT port configuration

The Component V/R / SDI OUT port can be configured by setting the position of link

PL2 & PL5 (to be found just above the middle right hand edge of the module). When a

component input is required set jumper link PL2 & PL5 to their upper position. Set

jumper PL2 & PL5 to their lower position when a further SDI output is required.

Note: Links PL2 & PL5 must be moved together as a pair.
