Television standards:Recently a lot has been accomplished to facilitate easy reception of foreigen broadcasts by simplifying television standards. The discontinuation of the high-difinition French 819 lines standard and the rather poor British 405 lines standard left the world with just 2 standards; 525 lines (generally accompanied by the American NTSC colour system) and 625 lines(usually in PAL or SECAM colour). The technical characteristics of the various transmission systems are given in the tables below.The colour standards (PAL, SECAM, NTSC) and television system used by each country are indicated at the top of the country entry. Antenna polarization varies from one transmitter to another and either (H)orizontal or (V)ertical.
