Travelling up, down and across the yellobrik road
The latest update to the PVD 1800 sees Lynx Technik AG add up/down/cross and aspect ratio conversion, as well as scaler functionality, to its yellobrik frame synchroniser. The upgrade reportedly adds to the system’s flexibility as a ‘multi-faceted solution in a thrown down brick form factor, addressing multiple applications’ and comes as a free firmware update with the download of the most recent version of yelloGUI from the manufacturer’s website. The yelloGUI control software itself has also been updated with a suite of new tools for the control and configuration of the new features using a PC or Mac.
The up/down/cross converter and scaler provide the ability to convert between video formats for facilities operating across multiple formats, including 3G, HD and SD-SDI. The aspect ratio converter, meanwhile, enables the PVD 1800 to switch a video signal’s aspect ratio by converting to letterbox/pillarbox, centre cut, stretch to fill, 14:9 and other custom conversions. This functionality is accessed via the yelloGUI software.
A region of interest (ROI) tool is also delivered with the scaler, allowing users to crop a selected region on the original video signal, scaling it to be viewed on the SDI output as a full size video. With this, Lynx Technik AG states that the user ‘has full control over the input signal cropping as well as the sizing of the output signal display’.
A fast scale mode that reduces the processing delay to less than 10 lines is also offered with the scaler tool, designed for use in applications that require a short processing delay and rapid conversion. It is noted that when fast scale is activated, the module’s frame synchronisation functionality will be automatically deactivated.
