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 between 0 and 2 fields.

Embed analogue or digital audio

EMDEC-200 allows you to embed exactly what you need, just by fitting the appropriate audio piggyback from Crystal Vision’s standard range. Fit the HD-AIP2 piggyback to embed analogue audio, the HD-DIP2 for synchronous AES or the HD-DIP2-RS for asynchronous AES. If you’re embedding analogue audio you must also fit a HD-DCDCV18 PSU.

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 frames (4U, 2U, 1U and desk top box), allowing full integration with any other interface or keying product from the Crystal Vision range. Up to 12 boards can be housed in a 2U frame.

It can be used with four different frame rear modules (RM04, RM07, RM26 and RM30) and gives a maximum of three SDI outputs.

Choose your control

The flexible control options include board edge, an active front panel on the frame, a remote control panel, SNMP or the Statesman PC Control System.
