When exhibiting a natively interlaced signal on the progressive scan gadget, the general spatial resolution is degraded by easy line doubling—artifacts, which include flickering or "comb" outcomes in transferring aspects of the picture that seem Until Unique sign processing gets rid of them.

An analog video structure includes more information compared to the noticeable content material from the body. previous and next the graphic are traces and pixels that contains metadata and synchronization facts.

Video can be interlaced or progressive. In progressive scan devices, Just about every refresh period updates all scan lines in Each and every body in sequence. When exhibiting a natively progressive broadcast or recorded signal, the result could be the optimum spatial resolution of both the stationary and transferring aspects of the picture.

In interlaced video, the horizontal scan traces of each finish frame are addressed just as if numbered consecutively and captured as two fields: an odd field (upper subject) consisting with the odd-numbered traces and an even area (decreased field) consisting from the even-numbered traces.
