Some 819-line TV sets were available, like the Grammont 504-A-31 from 1951 [7] and the Philips 14TX100 multi-standard 625/819-line TV from 1952. [8] [9] The system was also adopted (with limited bandwidth, affecting image resolution) in 1953 in Belgium [1] [4] by RTB and in 1955 in Luxembourg by Télé-Luxembourg. [10]
The PAL-L (Phase Alternating Line with CCIR System L broadcast system) standard uses the same video system as PAL-B/G/H (625 lines, 50 Hz field rate, 15.625 kHz line rate), but with a larger 6 MHz video bandwidth rather than 5.5 MHz and moving the audio subcarrier to 6.5 MHz. An 8 MHz channel spacing is used for PAL-L, to maintain compatibility ...
A version of SECAM for the French 819-line television standard was devised and tested, but never introduced. [3] Following a pan-European agreement to introduce color TV only on 625-line broadcasts, France had to switch to that system, which happened in 1963 with the introduction of "la deuxième chaîne ORTF" France 2, the second national TV ...
C – Belgian 625-line system, 7 MHz video bandwidth; D – I.B.T.O. 625-line system, 8 MHz video bandwidth; E – French 819-line system, 14 MHz video bandwidth; F – Belgian 819-line system, 7 MHz video bandwidth; On UHF bands Bands IV and V only 625-line systems were adopted, with the difference being transmission parameters like channel ...
819-line was a monochrome TV system developed and used in France [2] [3] as television broadcast resumed after World War II. Transmissions started in 1949 and were active up to 1985, although limited to France, Belgium and Luxembourg. [4] It is associated with CCIR System E and F. [4]
CCIR System F was an adaptation of System E used in Belgium (1953, RTB) and Luxembourg (1955, Télé Luxembourg).With only half the vision bandwidth and approximately half the sound carrier offset, it allowed French 819-line programming to squeeze into the 7 MHz VHF broadcast channels used in those neighboring countries, albeit with a substantial loss of horizontal resolution.

The problem got worse with the introduction of color standards PAL, SECAM (both 625 lines), and the French black and white 819 line service. Until the 1980s, standards conversion was so difficult that 24 frame/s 16 mm or 35mm film was the preferred medium of programming interchange.
CCIR System E is an analog broadcast television system used in France and Monaco, associated with monochrome 819-line high resolution broadcasts. [1] Transmissions started in 1949 [2] and ended in 1985.
