Three products on one board
EMDEC-200 is Crystal Vision’s broadcast embedding decoder, designed to offer the functions of three products on one board.
It replaces a decoder with synchroniser, tracking audio delay and embedder and handles the whole input into an embedded system in a convenient, space-saving and inexpensive way.
With its ability to make systems 25% cheaper, EMDEC-200 is aimed at anyone who needs to bring analogue video into an embedded environment.
Deal with any signals
EMDEC-200 converts PAL/NTSC composite or Y/C 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.
Perfecting the output picture
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. Adjustable timing, gains and levels all help to perfect the picture.
Synchronise your input
The on-board frame video 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 up to one frame apart.
Embed analogue audio
EMDEC-200 allows you to embed analogue audio, just by fitting the 3G-AIP2 audio piggyback.
A 2 x 2 stereo router allows the shuffling of stereo pairs, while the audio can also be monitored from the front of the board using headphones. High quality audio is guaranteed with Crystal Vision’s audio protection.
Keeping the video and audio in time
The internal tracking audio delay tracks the video delay, running the audio fast or slow to ensure the video and audio stay correctly timed and to avoid lip sync errors. You can also add 20ms of fixed audio delay on top of the tracking to compensate for early audio. Predictive tracking can be used to minimise the offset between audio and video delay when video frames are dropped or repeated.
An audio follow output pulse also allows EMDEC-200 to be used with an external tracking audio delay.
Save rack space
EMDEC-200 is a 100mm x 266mm module which fits in the standard Indigo frames (2U, 1U and desk top box), allowing full integration with any other interface or keying product from the Indigo range. Up to 12 boards can be housed in a 2U frame.
It can be used with two different frame rear modules (RM04 and RM26) and gives a maximum of three SDI outputs.
Flexible control
The flexible control options include an integrated control panel on the AE frame, the VisionPanel remote control panel, SNMP, our ASCII and JSON protocols, the Statesman Lite PC Control System or the VisionWeb web browser control. Try the EMDEC-200 VisionWeb demo...

VIDEO TIMING ADJUSTMENTS
With a video timing reference the timing of the output (with respect to the reference in) may be adjusted by any number of lines up to a whole video frame. Horizontal timing adjustment is also possible in 37nS steps
With no video timing reference the delay from input to output is set by the same timing adjustments
DELAY THROUGH BOARD

FREEZE FUNCTIONS
Manual freeze allows EMDEC-200 to be used as a simple still store. Selecting single field output can counteract any flicker caused by the interlacing of two fields. Either field can be selected
AUDIO INPUTS
One 3G-AIP2 piggyback can be added to the main board to enable input of 2 x analogue stereo pairs to be embedded into a single audio group
AUDIO TIMING ADJUSTMENTS
The audio is normally delayed by the same amount as the video but an additional delay can be added to the audio of up to 20ms

What outputs do I get?
Signal inputs and outputs are accessed by using an appropriate rear module.
The Indigo rear modules slot on to the back of the frame and typically feature BNC, D-Type, RJ45 and optical connectors. The single and double slot rear modules can be used with all three frame sizes, while the quad slot rear modules just fit the 2U frames.
