Organization Internationale de Radiodiffusion et de Télévision

from Wikipedia, the free encyclopedia
Former members of the OIRT

The Organization Internationale de Radiodiffusion et de Télévision (OIRT; German : International Radio and Television Organization ) was the umbrella organization for radio and television broadcasters in Central and Eastern Europe , based in Prague . It was founded on June 28, 1946 under the name Organization Internationale de Radiodiffusion (OIR) in Brussels .

After the fall of the Berlin Wall, the members decided to dissolve themselves in 1992. Their radio stations or broadcasting corporations were incorporated into the European Broadcasting Union (EBU) founded in 1950 . Most recently, members of the OIRT were broadcasters from Bulgaria , Finland , Cuba , Hungary , North Korea , Poland , Romania , the successor states of the Soviet Union , Syria and Vietnam ; Associate members ARD , ZDF and Mongolian radio .

OIRT and Intervision

The task of the OIRT was the mutual exchange of information about program design and the promotion of technical development as well as, via Intervision, the program exchange between the members and on Eurovision . In 1966 there were 24 OIRT members, 13 of whom also participated in the Intervision. The broadcasting corporations of the neutral states Austria ( ORF ) and Finland ( YLE ) were members of the western EBU (Eurovision) as well as the eastern OIRT (YLE) or at least participated in the Intervision (ORF).

All member states (with the exception of the GDR ) used a special frequency band for VHF broadcasting stations that was below VHF band II (87.5–108.0 MHz) used in Western Europe . This OIRT band (65.9 MHz – 73.1 MHz), also known as FM low or FM-OIRT , is still used in Russia today, but is rarely used anywhere else. Most of the stations have now switched to Band II, known as FM- CCIR (high) . There are also radio sets on the market that can switch between the two radio bands.

The OIR / OIRT standard was used for television transmission with a difference between the image and sound carrier frequencies of 6.5 MHz ( intercarrier method ). Initially also in the GDR, but there was a change to the CCIR standard (distance 5.5 MHz) in 1956/57.
