![]() In the UK PAL televisions operates at 25 frames a second with 50 fields a second (USA 30 frames a second with 60 fields a second). So each half frame is shown and is slightly different. Interlacing is when these two fields are shown in sequence at twice the rate of the actual frame and at half the resolution. One of the two fields contains the odd lines and the other field contains the even lines. AnswerOn an Interlaced Picture the scan lines of a frame are arranged in two fields each. Stations have already committed to either one of the standards and will be unlikely to change anytime soon. When will they switch to 1080P? They won't it took over fifty years for the government to change the standard and it hasn't even been effect yet. ![]() #What is better 1080p or 720p tv#over 85% of tv networks are being broadcast into 1080i the rest is 720P. It also depends on the output of the signal being sent into the HDTV. So technically 1080p is better especially when you watch closely. Because each frame is composed of two separate lines being displayed and two moments in time, if the recorded object moves fast enough to be in different places when each field is captured it creates a 'combing' affect. 1080p is technically better to watch, but theoretically worse because it does not have the two sets of 540 interlaced lines being displayed alternately. The human eye can actually tell the difference very well, especially when watching fast action or sports. For a 1080p screen to be noticably better than a 1080i one, you would probably need a screen size of over 60". ![]() I think that 1080p does give a better picture, but you can only start to appreciate it on the bigger sized tv. Human eye cannot differ the two resolutions, so paying an extra £1000+ for 1080p is definitely wasted money. 1080p - the frame is produced by using a single progressive scan.ġ080i - the frame is produced by using two simultaneous diagonal scans.
