480x576
480x576 is a digital image or video frame size defined by a width of 480 pixels and a height of 576 pixels. It is commonly associated with standard-definition video in PAL-region systems, where 576 lines contribute to the vertical resolution of the signal. When the frame uses square pixels, its native display aspect would be 480:576, roughly 5:6, but many pipelines apply a pixel aspect ratio to map the frame to standard display proportions such as 4:3 or 16:9.
In practice, 480x576 frames are often encountered as cropped, scaled, or downsampled variants of broader SD
From a data perspective, an uncompressed 8-bit RGB frame at 480x576 would be approximately 0.87 megabytes, while
Historically, PAL SD video commonly used 720x576 or 704x576 as standard framing sizes; 480x576 may appear when
