The first colour TV I saw was 405 50 NTSC (an experimental setup some years ago.) My mind wanders back to 1964 when I used to come home from school to watch the colour test transmissions at 4:00 PM every weekday on the BBC. They were 20 minutes long and comprised, IIRC, She Wore A Yellow Ribbon with John Wayne split into 20 minute segments and a series of very interesting documentary films which included the moving of the temple at Aswan and building an oil rig in the jungle. Most of the films that were used for these test transmissions were either promotional films from the likes of Shell or public information films. A few feature films appeared from time to time - all from RKO, as far as I can ascertain - and often only excerpts. The reason that longer films were split was that there was only one colour telecine machine at Lime Grove, so each reel had to be transmitted individually with colour bars and/or slides in between. Some that I recall a The Home-Made Car (BP), Hook, Line and Sinker (Esso), Beauty in Trust (National Trust), Coupe des Alpes (Shell), The Captive River (Shell), Colour Television (Mullard), Prospect for Plastics (Shell), A Question Of Springing (Shell), The Hydraulic Transmission of Power (Shell-Mex/BP), Evoluon (Philips), A Journey into the Weald of Kent (National Benzole), On the Safe Side (UKAEA), Overhaul (British Transport Films), The Power to Fly (Shell), Skyhook (BP), The Rival World (Shell) Diavolezza (BP), Crown of Glass (Shell). The full list is he http://www.testcardcircle.org.uk/ttcfatoz.html Thanks for that Terry, my mind only remembers a few highlights nowadays :o) The thing I didn't mention which was relevant to the discussion was that the test transmissions were on the 405 line setup and not the 625 line which came in later on in 1964. I started work in 1967 and joined the television trade just as colour sets became available. One of my jobs as an apprentice was assisting the engineers with installations as it took 2 men to even lift the sets in those days. While the engineer "installed" the set, I was able to drink tea and chat with a lot of well known people and celebrities as they were the only ones who could afford a colour set in those days. I still have all the autographed pictures. -- Frank Kelly |

Fascinating material and many of them still have interest. |

When I buy things like that, I Google them first with the keyword 'hack' or similar to find out if it's possible to enable multi-region. Related question; UK PAL is what, 625 lines @ 50fps, and US NTSC is 525 lines @ 60fps - so as well as being unlocked, does the DVD player also have to be capable of scaling and compensating for different frame sizes and rates on the fly? Note that your fps above refers to fields, not frames (as the picture is interlaced). Most players will just output at the relevant frame rate and leave the display to deal with decoding it. Even the last couple of generations of CRT TVs could usually handle any standard input signal. Some DVD players will output a "PAL60" signal which is a non-standard 60hz 525 line picture but with PAL colour subcarrier rather than NTSC (PAL was a better quality system than NTSC). Some modern players of course output upscaled pictures over HDMI or component video, and some will output a 480p picture from an NTSC disc. TV shows etc. recorded onto a DVD will typically have been shot originally in 50i (PAL) or 60i (NTSC). But movies are typically shown at 24 frames per sec at the cinema. When movies are shown on the 50Hz PAL system (either broadcast or on DVD), they are usually sped up to 25 frames per second, to fit in with the PAL frame rate. This results in slightly higher-pitch sound and a slightly shorter run-time. But on NTSC DVDs movies are typically recorded at 24frames per second and the player will insert additional frames to be able to output a 30 frames per second (60Hz) NTSC interlace signal. This can cause significant motion judder. Many modern TVs will accept a 24 frames per second progressive scan input, and upscaling DVD players will often have a 24 fps 1080p playback mode. In this mode, the DVD plays back at the original 24fps frame rate. |
