      @thecreativeone91 Broadcast isn't standardized, as every network may choose to broadcast at a different resolution or aspect ratio.

      That's not true for broadcast.

        What? 720 is the entry HD thing that was a way to ease into higher resolutions. Full HD is the 1920x1080.
        Also the P is irreverent to resolutions. That refers to progressive video. Many broadcast stations still do interlaced which manes two "frames" are put in one by using upper and lower fields of the video. HD, SD etc, etc. Can be either Progressive or interlaced.

          "Commonly" is a tough term here. Commonly by consumers being sold cheap displays? Commonly people know that marketing people will use this term to fool them? Sure, that might be common, or maybe not. Normal people don't understand any of these terms. The number of people being sold them is many times higher than the number of people with some understanding of them and the number of people who really know what is intended or being said is a small subset of that.

          Ask an average person what HD means, and they will probably have no idea what 1080p is but they will likely state that it is "high definition", which is the opposite of what 720p is today.

            My Dreamcast was 480p SD. No widescreen, but it looked good.

              @thecreativeone91 Maybe broadcast is more locked down in the US, but with Digital Broadcasting, a network can stream at the resolution and aspect ratio that it wants. The TV receiving it will downsample or stretch the image, but that's up to the hardware on the user end. And HD does not refer to Interlaced Scan video, only Progressive Scan. Interlaced is used for TV broadcasting, and the occasional piece of professional equipment, most everything else is progressive scan.

                Broadcast is VERY stringent in the US. What is allowed to be broadcast is crazy specific because it uses publicly shared airwaves. Broadcasters get a few choices, yes, but they are all pre-determined and very, very specific.

                  The FCC lockdowns are useful in ensuring that television reaches the poor who haven't bought a new television in decades. But it also guarantees broadcast television irrelevance. It was useful long ago, today I think it is self defeating.

                      That's not true for broadcast.

                      Here is what the FCC allows.

                      1280x720 Square Pixels
                      Progressive Frame Rates: 23.976 24 25 29.97 30 50 59.94 60
                      Interlaced: Not allowed

                      1920x1080 Square Pixels
                      Progressive Frame Rates: 23.976, 24, 25, 29.97, 30
                      Interlaced Frame Rates: 25, 29.9, 30

                        HD does not refer to either one. It's resolution only. Resolution, Frame rates and Progressives vs Interlaced is are all separate things. You are badly misinformed.

                          None of that is "common" besides someone who is misinformed about the specifications.

                            @Dashrender There's your answer. Film is done to look good, TV is done to comply to stringent FCC rules.

                              @thecreativeone91 If all categorization was based off of ACTUAL common knowledge, the world would be in misinformed chaos, consumers don't know what they're even buying, much less how it works on the inside. The world of technology is far too specialized to rely on common knowledge for anything.

                                  The FCC only adopts the rules created by the broadcast associations. It would be impossible to do the level of a Film OTA. You get shipped multiple harddrives that create a raid to plug directly into the the digital projector both because of size and needed data rates to get high quality. Film is DPX files, one file per frame (it's actually just a large picture file with no compression). Audio is done separately, and synced with timecode.

                                      You are confusing TV with Broadcast TV. Only Broadcast TV, which is a trivial component of TV today, has FCC rules. Most TV has not had any FCC oversight for a very long time (cable, Internet, etc.)

                                        Which is why we need to work with specifics, not non-standard marketing terms when specifying things. Terms like HD, 4K, UHD, etc. are used to confuse, not to inform. There is no governing body overseeing them so even attempts to "standardize" them are marketing attempts as they cannot be standardized after the fact - it simply can't be done. Thinking that a standard can be applied after the fact is part of the problem - consumers believe that there is some ratified standard that protects them and stop paying attention when, in fact, there is no such thing and no one to enforce it. So the more we "feel" it is standardized, generally is just an artifact of being marketed to very well.

                                          That's completely made up. That is in no way an agreed upon use of English, common knowledge, industry accepted standard of anything. If there is one thing that HD routinely is not, this is it.

                                            Keep in mind that films actually have a vested interest in you wanting to come out and watch a good high quality movies.

                                            Broadcast and cable, just care that you happen to see commercials when a TV is on. They could careless if you watch or like it. And Cable even more so since there is a lot of double dipping (subscription price + ad revenue) Imagine if Netflix charged you then showed you a lot of ads. Granted Hulu does this I think.
