Summary
[edit]DescriptionSMPTE RP-133 small.png |
I (Rich Franzen) digitally built this image around 1987 using the SMPTE RP-133 specification as a base. It was originally used as a test image by the DFR-8000 digital film recorder in the mid-to-late 1980s. Both the recorder and its manufacturer, DBA Systems, Inc. are long gone, although L-3 Communications is the company which bought the company which bought DBA. I was granted permission to use the image freely, and it has appeared on my site since 1998. This "small" version is extracted from the full image. It deviates from the RP-133 specification in one respect. An apparant smaller SMPTE pattern is within it, but that pattern is heavily sampled downward. Admittedly this addition means the image is no longer fully compliant with the SMPTE specification. The formal name for the SMPTE specification in question is "SMPTE Medical Diagnostic Imaging Test Pattern". |
