1、CEPTERUREC 25-10 E Page 1 Distribution: B CEPT/ERC/RECOMMENDATION 25-10 E (Bonn 1995) FREQUENCY RANGES FOR THE USE OF TEMPORARY TERRESTRIAL ENG/OB VIDEO LINKS DURING EVENTS IN OTHER CEP“ MEMBER COUNTRIES Recommendation proposed by the Working Group “Frequency Management“ (FM) Text of the Recommendat
2、ion adopted by the “European Radiocommunications Committee“ (ERC): INTRODUCTION Temporary terrestrial ENG/OB video links are used for a number of applications, mainly relating to services ancillary to broadcasting. The video links are operated to cata for a variety of broadcasting reqwirements, incl
3、uding TV Outside Broadcasting (programmes made outside a studio) and TV news gathering, including Electronic News Gathering. A feature of News Gathering is that the event to be reported upon may be unpredictable (time and location) and may necessitate a very rapid response. In such cases, it is very
4、 important that the delay and the procedures for frequency coordination and licensing are limited to the minimum. OB, on the other hand, is normaily planned in advance of an event. ENG/OB video links operate makly in non-harmonised frequency bands above 1 GHz, moreover, the use of this equipment is
5、not harmonised in CEPT member countries due to divergent national fieqnency plans and requirements. The Recommendation draws attention to the frequency bands currently used and identifies harmonised frequency tuning ranges that can be used for ENG/OB video links in other CEPT member countries. The c
6、oncept of harmonised tuning ranges has been adopted so as to enable standardised ENG/OB equipment to be used both in frequency bands allocated on a national basis for ENGIOB video links, as well as for occasional use in other fequency bands within the harmonised tuning range. With this concept maxim
7、um operational flexibility is assnred and there is no need for CEE wide harmonisation of specific frequency bands for ENG/OB video links. Furthermore guidance is given for the issuing of (temporary) licences. “The European Conference of Postal and Telecommunications Administrations, considering a) t
8、hat video link equipment such as Electronic News Gathering (ENG) and Outside Broadcasting (OB)3 are increasingly being used at national and international events in CEPT member countries; Tuning range is the frequency range within which the equipment is capable of being tuned to any one in a range of
9、 specified frequencies whilst maintaining the required technical and operational characteristics. ENG = Electronic News Gathering (ENG) is the collection of television news stories without the use of film, using small hand-held, electronic, colour cameras with microwave links to the news-room and/or
10、 portable video tape recorders. (CCIR report 803-2, annex to Volumes X and XI, parts 3). OB = Outside broadcasts is the temporary provision of programme making facilities at the location of ongoing news, sport or other events, lasting fom a few hours to several weeks. Outside Broadcasts are generall
11、y planned in advance, but it is often necessary to accommodate short notice changes of venue or unforeseen requirements. Video links are required for mobile links, portable links and cordless cameras at the OB location. Additionally. Video links may be required as part of a temporary point to point
12、connection between the OB van and the studio. Edition of May 1, 1995 STD-CEPT CEPT/ERC/REC 25-10 E-ENGL 1995 H 232b414 0014503 945 CEPT/ERC/REC 25-10 E Page 2 that the current analogue video link equipment has no continuous frequency tuning range and bandwidth adaptation facilities; that national br
13、oadcasters and programme makers may be required to operate in other CEPT member countries; that coordination may be required to ensure that the use of this equipment does not cause interference to other systems and service.; that the use of ENG/OB video link equipment on board aircraft shail be coor
14、dinated or authorid, if required, with the national civil aviation authorities; that lack of harmonised kxpency tuning ranges creates difidties for national broadcasters and programme makers when operating in other CEPT member countries; that there is a need for the identification of lequency timing
15、 ranges for the use of temporary terrestrial video link equipment during events in CEPT member countries; that identification of such frequency tuning ranges will also facilitate the development of standardised equipment; noting that the introduction of new technology may facilitate the development
16、of terrestrial ENG/OB video link equipment capable of operating more flexibly; recognising 1) that the ERC has agreed Report no. 25 relating to the Table of Harmonised Frequency Allocations and Utilisations in the frequency band 960 - 3400 MHz as the first step in development of the Table to be impl
17、emented in CEFT member countries not later than June 2008; 2) that in several CEFT member countries temporary terrestrial ENG/OB video links have already successfully shared frequency bands with tactical relay systems for military purposes and the fued service for Public Telecommunication Network or
18、ganisations; 3) that the CEPT Administrations have identified frequency bands and technical characteristics as set out in Annex 1 (to be developed) “Frequencies for temporary video links (services ancillary to broadcasting)“ ; recommends: 1) that CEPT Administrations should be flexible in considerin
19、g requests from foreign broadcasters and programme makers for the use of frequencies for temporary terrestrial ENG/OB video links as mentioned in : a) the table of national allocations for ENGIOB as given in Annex 1; b) Annex 2 of the Recommendation; Edition of May 1,1995 that the frequency tuning r
20、anges for future terrestrial ENG/OB video link equipment for temporary use in CElT member countries should be established in accordance with Annex 2, and that the technical characteristics for ENG/OB video links should be in conformity with Annex 3; that CEPT Administrations shaii indicate through i
21、ssning an individual licence, after coordination has been successfully obtained, that the use of ENGIOB video links equipment is authorised during a temporary stay, on a non-protected and non-interference basis; that CEFT Administrations should use simplified and flexible procedures for issuing temp
22、orary licences for the use of this equipment; that CEW Administrations should have readily available temporary licences and application forms for ENG/OB video Ws equipment. The application form may take the form as set out in Annex 4; that CEFT Administrations should encourage use of frequency range
23、s above 5 GHz for ENG/OB applications and only permit use of frequency ranges below 5 GHz for ENG/OB applications where required by propagation characteristics; that CEFT Administrations should encourage the introduction of ENG/OB video link equipment having continuous frequency tuning range and pos
