These modules convert HDMI video to and from SDI video signal formats up to 3Gbit/s, providing a means to use consumer hardware such as camcorders and TV screens in a professional digital environment with no image compression. Part of the Yellobrik range manufactured by Lynx Technik, they all offer fibre input/output capabilities by means of optional SFP fibre modules. HDMI to SDI converters are available with or without frame synchroniser and analogue audio embedding. An SDI to HDMI conversion module offers, in addition, audio de-embedding and on-screen monitoring of data embedded in the SDI signal. The range includes designs for use with either unbalanced AES digital or balanced analogue audio. Modules may be used alone, or mounted in an optional rack-mounting frame.
yelloGUI Software Application for Yellobriks
Where required, key settings for yellobriks are controlled via the rotary switches and DIP switches on the front panel, with status shown on indicators on the front panel. The new yelloGUI, software application provides extended and enhanced access to internal yellobrik settings and controls, many of which are not accessible from the unit's controls and switches. It is free to download and permits selected yellobriks to be controlled and configured over USB using a PC. The yelloGUI user interface, like the yellobrik modules, is simple and intuitive to use. Once the module is connected, a virtual image of the module is displayed showing the user an enhanced range of all switches, controls and module indicators. yelloGUI also displays status information such as the detected video format, HDMI output resolution and frequency, as well audio signals. The internal signal flow inside the yellobrik is displayed graphically and changes dynamically when a setting is changed.

Included accessories: All Yellobrik modules are supplied with a plug-top power supply with UK, US, Australian and European plug fittings, wall-mounting brackets and a plastic transport case.
Optional accessories: Fibre transmitter or transceiver modules, see below. Power adapter cables for 12V working, alternative power supplies and a rack-mounting frame for to 14 Yellobrik modules are available. Please see Lynx Yellobrik power supplies and mounting accessories.
This simply converts an HDMI input into an SDI output, 3D is supported. Any audio present in the HDMI stream will be embedded into the corresponding channels on the SDI output. Applications might include using the HDMI output from an inexpensive camcorder in a digital environment using no image compression.
There are BNC connectors for two SDI outputs. A type A connector provides the HDMI input. LEDs indicate HDMI video and power are present.
The CHD 1802 is compatible with the yelloGUI software application.
Included accessories: An HDMI cable is provided in addition to the standard inclusions.
Optional accessories: Either an OH-TX-1 or OH-TX-3-1550 fibre transmitter SFP module may be fitted, see below, to provide an SDI output over fibre. A range of CWDM fibre transmitter modules may also be fitted, see CWDM SFP modules.
CHD 1812 - HDMI to SDI - Frame Sync - Audio Embedder
This provides a fully-synchronized SDI input from an external asynchronous HDMI source. 3D is supported. The reference sync input will accept any analogue video sync format including SD bi-level sync, black burst, colour bars 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. External audio and HDMI inputs are frequency-locked to the external reference.
A stereo pair of analogue inputs can be embedded into any AES channel. A rotary switch selects the audio channels; a second rotary switch select the full-scale level for the balanced audio outputs, which may also be used unbalanced. Any audio present in the HDMI stream will be embedded into the SDI outputs, or can be replaced with the external audio inputs, which over-write the channel.
Reference input: SDTV, analogue 525 or 625 bi-level sync, black burst or colour bars; HDTV, all tri-level sync standards (exceptions 1080p 50/59.94/60Hz); SMPTE 274M, SMPTE 296M, 75 ohms, BNC.
The CHD 1812 is compatible with the yelloGUI software application.
Included accessories: An HDMI cable and a pair of RCA(phono) to jack adapters are provided in addition to the standard inclusions.
Optional accessories: Either an OH-TX-1 or OH-TX-3-1550 fibre transmitter SFP module may be fitted, see below, to provide an SDI output over fibre. A range of CWDM fibre transmitter modules may also be fitted, see CWDM SFP modules.
CDH 1813 (replaces and enhances CDH 1811) - SDI to HDMI
The CDH 1813 yellobrik replaces the CDH 1811 SDI to HDMI converter and offers an enhanced feature set for audio/video monitoring and display applications. It will convert any SDI video signal into a standard HDMI signal for monitoring and display. Input standard and format is detected automatically. The HDMI output displays the native input resolution therefore no scaling artefacts are introduced. A new feature in the CDH 1813 module is the addition of 3D format support, making this yellobrik suitable for monitoring single-link 3D SDI streams on a 3D HDMI monitor. This supports side-by-side, top and bottom, as well as frame-packing 3D HDMI display modes.
Two channels of audio can be de-embedded from the incoming video signal and provided as AES digital outputs and analogue audio signals. A rotary switch selects the audio channels; a second rotary switch selects the full-scale level for the balanced audio outputs, which may also be used unbalanced. The two selected audio channels can also be embedded into the HDMI output; alternatively eight channels may be selected from the input signal, either channels 1-8 or channels 9-16.
The module has the capability to overlay data from the incoming video signal on the HDMI output. There are windows for time-code, four groups of four embedded audio channels, key metadata information as well as AFD code.
There are BNC connectors for SDI in and out, AES audio out. Two 3-pole 6.35mm jacks provide analogue audio out. A type A connector provides the HDMI output. LEDs indicate video, audio and power are present.
An optional fibre interface allows the module to be used for monitoring fibre connections and also function as a SDI to fibre converter. When the fibre transceiver option is fitted the module may be used with either an electrical SDI input or a fibre input signal, selected by a DIP switch. The module will provide both a fibre and electrical SDI output of the selected input signal as well as the HDMI output.
The CDH 1813 is compatible with the yelloGUI software application.
Included accessories: An HDMI cable and a pair of RCA (phono) to jack adapters are provided in addition to the standard inclusions.
Optional accessories: Either an OH-TR-1 or an OH-TR-3-1550 fibre transceiver SFP module, may be fitted, see below, to provide a fibre SDI input and a re-clocked, fibre loop-output. A range of CWDM fibre transmitter modules may also be fitted, see CWDM SFP modules.
These plug into the 'cage' on the side of the module and can be added at any time, to provide an SDI output over fibre. They use an LC/PC single mode fibre connection.
Note (1): Maximum.
Fibre Transceiver SFP Modules - OH-TR-1, OH-TR-3-1550
These plug into the 'cage' on the side of the module and can be added at any time. The 'transceivers' can receive one SDI signal from one fibre and transmit an SDI signal over a second fibre simultaneously. They use an LC/PC singlemode fibre connection.
Note (1): Maximum.
