CHD 1412
12G-SDI HDMI to SDI Converter with Frame Synchronizer
The CHD 1412 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 sync. The sync input is auto detecting and fully cross lock compatible. For example: An SDTV 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. It can also lock to the HDMI input. A pair of stereo analog inputs can be embedded into any AES channel. Audio inputs can be either professional balanced audio with selectable full scale level, or unbalanced consumer line level audio. By default any PCM audio present in the HDMI stream will be embedded into the SDI output [encoded audio such as AC3 / DD+ etc. is not supported] or it can be replaced with the external audio signals.
The module is also compatible with LynxCentraal and yelloGUI software packages, which provide access to a host of additional internal settings including adjustable video delay for timing purposes.
An SDI fiber output is also provided with a variety of plug in SFP options available.
Note: For legal reasons, HDMI capture devices 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, etc.).
