A.3. PRODUCTION, CLEAN APERTURES AND ANALOG TRANSMISSION BLANKING
The production aperture as defined above is the maximum possible image area that can be supported by
the video standard. The clean aperture is a slightly smaller image area of similar, but not necessarily
exactly the same aspect ratio and is usually concentric with the production aperture.
In PAL and NTSC, the nominal transmission blanking (analog aperture), is smaller than the production
aperture. Because the transmission blanking varies from location to location the calculations of aspect
ratio and size are usually referenced to either the production aperture or the clean aperture, which are
fixed for a given video standard.
