Blu-Ray, DVD And Multi-Region, Codefree, Region Free Variations And Super-Human Vision

Those are the basic standards and none are compatible with each other. Sometimes the A/C Hertz are 50 MHz (220 volt countries) and sometimes 60Mhz (110 volt countries) and this changes the scanning results of an electron tube, LVD or Plasma etc. 60Mhz, used in the USA for example, renders the image smoother, virtually no discernible flicker. With line doubling and quad-doubling (100 and 220 MHz and then 200 and 440 MHz).

Line doubling actually interlaces the picture into a single scan that reveals the entire frame and doubling again increased the scan lines providing for an even finer resolution and there a better sense of reality to the human eye. Technically it takes the original two-field frame and creates a progressive scan (single non-interlaced frame) output. This produces a higher resolution picture both brighter and smoother.

Some 3rd party Line-quadruplers can upscale to resolutions: 1365×1024, 720P, 1080i 852×480, 1024×1024, 1024×768 and 1365×768 and even higher. When the 澳門電子商務 newest technology in video images hits the world we will be seeing NHK images of more than 6000 lines, up from the maximum of 1080P today.

If they then begin to Line-quadruple an image like that who knows what the mind might achieve if plugged directly into the motherboard of the future. Perhaps an enlarging and enhancing of human vision will be needed in the order of 1,000 eyes, 360 degree views both laterally and longitudinally, 100,000,000 lines of resolution all far outpacing current human ability.

Back to PAL-NTSC for a moment.These many video systems were created due to incompatible electrical standards such as the Hertz, due to economic exigencies and even political motivations (for example, a country didn’t want its TV to be seen by another countries citizens nearby lest they get “ideas”!With the advent of DVD disc players Hollywood producers decided to take advantage of the new electronic potential inherent in this new groundbreaking technology to better market their movies.

With movies released in VHS VCR tape versions but in 5-6 different and non-competing systems the release of movies worldwide could be staggered according to best marketing practices so rake in as much profit as possible from every country. A movie released in April in the USA didn’t have to be released until the right time in South America and the idea of people in Argentina (PAL-N) wishing to buy the film from a US retailer was virtually a useless plan as the Argentine would have no VCR and no TV of the correct system to play and display the images with. PAL-N and NTSC simply do not display correctly on the wrong systems, even the speeds of recording and playback are different. This means an NTSC movie seen on a PAL or other standard would usually be in black and white, have terribly vertical scrolling problems, have a horizontal skew at the top of the picture and be in the wrong speed so even the voices were too fast or too slow. It’s a mess!
