Whether you need to insert Active Format Description data or read it, Crystal Vision can provide a suitable product. You'll find this AFD functionality in some of our synchronisers and up and down converters.
HD programmes are often made of a mixture of true High Definition sources and SD-originated sources that have been up converted and have black pillars at the sides. The AFD data in the signal gives information about which areas of the screen contain a picture and which areas have black 'padding'.
The AFD inserters add SMPTE 2016 AFD, WSS or Video index data to a signal which provides picture format information to downstream equipment to allow it to automatically select the appropriate aspect ratio. The AFD readers can dynamically select the best aspect ratio conversion based on the SMPTE 2016 AFD, WSS or Video index data present in the incoming video.
We no longer offer a dedicated aspect ratio converter, but our up and down converters range can be used for aspect ratio conversion if required.
