Some parts of the line (horizontal blanking) are reserved for signaling for the TV and don’t get “drawn” (in CRT-speak, the picture is “painted” or “drawn” by the electron gun in the CRT). For analog NTSC there are 525 horizontal lines in a frame and 29.97 frames/s. In the US, a broadcast TV signal has 6 MHz of bandwidth available to it. It wasn’t until MPEG-2 that support for fields came along. Even MPEG-1, an ISO standard, got it wrong (from the vidiot’s perspective) with only support for (progressive) frames. Are you crazy?), pixel aspect ratios (square? Square? Maybe you are, but our pixels aren’t!)…and not the least of which was an utter lack of understanding of interlaced video. There were a number of complaints – performance (dropping a field is not acceptable under any circumstances), color spaces (no we do not use graphics RGB. Back in the 80s and 90s when computers were first being used to manipulate TV, one of the common complaints (at least from my “vidiot” colleagues from the true video side of the industry, like Ampex and Abekas), was that computer (graphics) people didn’t know video. The introduction of computers to analog television wasn’t exactly graceful. Interlaced video grew out of analog television, and understanding exactly how interlaced video works in the analog world gives a lot of insight into how it’s best handled in a progressive world. And no, you are not allowed to slap two fields together that way. Well if you see things like that, then the video’s being processed incorrectly. Most people think of the dreaded fingering that can occur when two fields are slapped together: There’s a huge misconception about interlacing artifacts, particularly among those who grew up in the digital television age with flat panel displays. Generally here its preferable to sacrifice a bit of resolution in favor of a higher (full-frame) refresh rate. Sports (and in general content that has high motion) tends to benefit more from progressive frame video.

The reason is that there aren’t 60 frames/s to begin with, and through some processing (telecine in the case of 24p source content), it’s possible to recover something resembling the original frame at the television. Movies and shows shot in 1080p/24 or 1080p/29.94 tend to do well when broadcast at 1080i.

Some types of content benefit from 1080i more than others, of course. 1080p/59.94 generally requires a higher bitrate than 1080i/59.94 to achieve the same perceptual quality, especially when you consider the amount of work that’s gone into post-processing interlaced content so it looks good on a progressive display. Progressive video is always easier to deal with than interlaced, and it’s so easy to process interlaced video incorrectly and get weird artifacts. Given a choice between interlaced and progressive video at the same resolution…and no bitrate constraints…I’d of course choose progressive. Perhaps it’s my analog video background, but I have a far more favorable view of interlaced video. Interlaced video, in comparison is said to be Just Plain Evil. progressive video and how progressive video is inherently superior. There’s been a lot of chatter about interlaced vs.
