What are Progressive Segmented Frames (PSF)?

Progressive Segmented Frames (PSF) The end result of many years of interlacing meant that most broadcast systems, especially hardware, were built to read interlaced footage. These systems are still widely used today because SD still is interlaced. However, HD standards support progressive footage in addition to interlaced video. The younger generation of engineers had to find […]

Understanding Terminology – Scanning and Interlacing

  Scanning Traditional electrical systems use electrons to transfer data, and electrons travel one at a time through a wire (it’s much more complicated than that in practice but for our purposes it’s okay to think of them as such). This almost forced engineers to design systems to scan the image one line at a […]
