What is abrivation of PAL broadcasting?

Answer 1

PAL is the abbreviation of "phase alternate line". It is a color encoding system for standard definition television developed in Europe and first used in England and Germany for color broadcasts. The encoding system allowed a full color television signal to be carried on a single cable or transmission channel and still remain entirely compatible with monochrome television receivers.

It is now used across almost all of Europe, Asia and Australasia with much of Africa and South America adopting it as well. The major alternative to PAL is NTSC- the encoding standard used throughout North America, parts of South America and Japan. Both encoding systems do the same job but are no directly compatible with each other.
