Comité Consultatif International des Radiocommunications
The Comité Consultatif International des Radiocommunications ( acronym : CCIR ; dt. International Advisory Committee for the radio service ) was a sub-organization of today's International Telecommunication Union (acronym: ITU - International Telecommunication Union). It was founded in 1927 at the Radiotelegraph Conference in Washington, DC and officially existed until 1992. In that year, the organization of the ITU was restructured; the CCIR merged into the newly created ITU-R ( Radiocommunication Sector ).
In its standardization work, the CCIR dealt among other things with the format of the analog BAS signal (which is why it is often referred to as "CCIR signal" for short). This is not to be confused with the digital signal CCIR 601 derived from it .
tasks
It was a permanent establishment of the ITU with its own organization. The contractual basis was contained in Article 14 of the International Telecommunications Treaty of Montreux 1965.
The tasks of the CCIR were the study of technical questions of the radio service and the issuing of recommendations for the most favorable solution of these questions. The recommendations were prepared in study commissions set up by the general assembly and decided in the general assembly. All ITU member countries were able to take part in the general assemblies and in the work and deliberations of the study commissions. Operating companies, industrial, scientific and international organizations could be admitted to the specialist consultations.
Facilities
General Assembly
The general assembly met as a rule every three years, for example in Oslo 1966. It elected the director about every six years, set up the study commissions and gave them assignments. The results of the plenary assembly were recorded as recommendations, reports and so on in the “final documents” of the respective plenary assembly, with the color of the cover indicating the language. The “Green Papers” are written in English and the “Blue Books” in French .
Director and Secretariat
The director ran the CCIR and coordinated the work of the plenary assembly and study commissions. The technical secretariat supported the director and took care of the day-to-day administrative work.
Commissions
The study commissions are appointed by the plenary assembly to carry out necessary investigations. In the late 1960s there were the following:
- a. Radio transmitter
- b. Radio receiver
- c. Fixed radio service systems
- d. Telecommunication systems of the space service
- e. Tropospheric wave propagation
- f. Ionospheric wave propagation
- G. Standard frequencies, time signals
- H. International radio surveillance
- i. Directional radio
- j. Sound broadcasting and program recording
- k. watch TV
- l. Tropical broadcasting
- m. Mobile radio services
- n. dictionary, symbols etc.
There was also the mixed working group CCI / IEC Graphic Symbols and the mixed committee CCIR / CCITT, CMTT, TV and sound transmission over long distances. There were also international correspondence working groups of the study commissions within the CCIR.
