The LYNX Technik CHD 1812 yellobrik is a versatile and compact HDMI to SDI converter with integrated frame synchronizer. It is an ideal solution for any application which requires a fully synchronized SDI input from an external asynchronous HDMI source.

The flexible reference sync input will accept any analog video sync format including SD bi-level sync, black burst, colorbars and tri-level HD sync. The sync input is auto detecting and fully cross lock compatible. For example: An SD black burst reference can be used to frequency lock an HD HDMI input. If no reference is present, the converter performs a standard asynchronous HDMI to SDI conversion.

A stereo pair of external analog inputs can be embedded into any AES channel. Inputs can be either professional balanced audio with selectable full scale level, or unbalanced consumer line level audio.

Any audio present in the HDMI stream will be embedded into the SDI outputs, or can be replaced with the external audio input.

On board SFP port is designed to for SDI fiber output (OH-TX-1) is also available as an add on option.

Note: For legal reasons, HDMI conversion products from LYNX Technik AG are designed not to capture, convert or transmit video or audio from HDCP copy-protected sources (e.g. Satellite receivers, Cable receivers, Blu Ray Players etc.)

          Comments about LYNX TECHNIK INC LYNX Yellobrik CHD 1812 HDMI to 3G SDI Converter w/Frame Synchronizer & SFP Port:

          Just keep in mind it doesn't split the 3D HDMI 1.4 into two separate camera feeds. It simply converts a SIDE by SIDE into two identical SDI Side by Side output signals. And it won't handle Frame Packing. Still useful if you have a 3D monitor like the Panasonic which only has SDI inputs. Probably other uses but I haven't thought of any. It works out of the box, no thinking...which is good.
