Page 5ETS 300 105: December 1991ForewordThis European Telecommunication Standard (ETS) has been prepared by the Terminal Equipment (TE)Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS has been produced in the light of:a)Videotex services being implemented in different countries using different data syntax profiles (asdescribed in ETS 300 072 [32]);b)the International Radio Consultative Committee (CCIR) expressing the view that terminal equipmentcompatibility should exist between broadcast Teletext 1)
systems for general reception and publicnetwork-based database systems;c)the right of different countries to use their existing systems;d)the possible requirement for transcoding and/or conversion to permit interworking between Videotexservices in different countries;e)interworking between Videotex services may be provided by using different types of networks suchas the Public Switched Telephone Network (PSTN), Packet Switched Public Data Network(PSPDN), Circuit Switched Public Data Network (CSPDN), Integrated Services Digital Network(ISDN), etc;f)the need for Videotex interworking protocols to offer a large degree of compatibility with thoseprotocols used in other telematic services.This ETS provides a number of technical provisions to enable the interworking of different Videotexservices at the international level, identifies the parameters required to communicate with Videotexterminals and certain technical recommendations for the potential interworking of other telematic serviceswith Videotex services.This ETS is also closely related , and normatively references, to three other ETSs (ETSs 300 072 [32],300 106 [33] and 300 107 [34]). Full details are given in Clause 2 (Normative references) of this Standard.
1)The term "Teletex" has not yet been definitively adopted by the CCIR.SIST ETS 300 105 E1:2003

Page 7ETS 300 105: December 19911ScopeThis ETS describes the characteristics of coded information that is exchanged between countriesparticipating in the international interactive Videotex service.Videotex systems are text communication systems having, in addition, the capability of a given level ofpictorial representation and a repertoire of display attributes. The text and pictures obtained are intendedto be displayed using the current television (TV) raster standards of the different countries.Different data syntax profiles are offered as a choice for the service providers to implement their services.Substantial degrees of compatibility exist between these options, but some transcoding and/or conversionmay be necessary to facilitate interworking.For the purpose of the international service, different data syntax profiles have been identified in ETS 300072 [32]:a)Profile 1;b)Profile 2;c)Profile 3;d)Profile 4;e)"ASCII";f)other data syntaxes are for further study.NOTE 1:"ASCII" uses the International Reference Version of the character set of the CCITTRecommendation T.50 and additional control functions for characters specified in ISOstandard 6429.NOTE 2:The use of this non-videotex data syntax is provisional and is pending the result of thework undertaken in the ETSI TE1/VT group as well as in CCITT.2Normative referencesThis ETS incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.
