Electronic Programme Guide (EPG); Protocol for a TV Guide using electronic data transmission
Specification of the EPG as an application of Electronic Data Transmission (EDT) within analog TV transmissions. The service provided by the EPG is scalable: Type 1: the user gets a Now and Next EPG for one braodcaster. Type 2: the user gets an EPG for today for one braodcaster. Type 3: the user gets a full EPG for more than one braodcaster. The tansport mechanisme is Teletext (see JTC work item DE/JTC-TTEXT-EACEM). The data transmission within Teletext (Coding) is subject of JTC work item DE/JTC-TTEXT-DT).

Page 7ETS 300 707: May 1997ForewordThis European Telecommunication Standard (ETS) has been produced by the Joint Technical Committee(JTC) of the European Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique(CENELEC) and the European Telecommunications Standards Institute (ETSI).NOTE:The EBU/ETSI JTC was established in 1990 to co-ordinate the drafting of ETSs in thespecific field of broadcasting and related fields. Since 1995 the JTC became a tripartitebody by including in the Memorandum of Understanding also CENELEC, which isresponsible for the standardization of radio and television receivers. The EBU is aprofessional association of broadcasting organizations whose work includes theco-ordination of its Members' activities in the technical, legal, programme-making andprogramme-exchange domains.

Page 9ETS 300 707: May 19971ScopeThis European Telecommunication Standard (ETS) specifies the data formats for data broadcastingapplications in general, and, specifically, for the Electronic Programme Guide (EPG) or TV Guide, alsoknown by some other commercial slogans. The data required for these applications is transmitted bymeans of a data broadcasting protocol using the Vertical Blanking Interval (VBI) lines of a TV signal. It isalso intended to coexist with other data-broadcasting applications running on affordable TV-sets, VCRs, ormulti-media PCs. The EPG enables a receiver/decoder to store a programme database (and, if available,a navigation database), which can help the viewer to find the programmes of his preference.2Normative referencesThis ETS incorporates by dated and undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter. For dated references, subsequent amendments to or revisions of any of these publicationsapply to this ETS only when incorporated in it by amendment or revision.

It comprises a number of streams.composite: A composite decoder is able to receive and to decode EPGs from more than one networkand to combine them into a single composite EPG.control data: This term is used to denote a combination of data fields in the EPG data structures whichundergo a special encoding procedure.escape sequence: A means of introducing additional, more complex display components into text strings(e.g. national characters, pictures).event: A predefined action which may be selected in a product's user interface menu.far programme: A programme which is not a near programme.Filtered (EPG): The EPG presented to the user is filtered if it contains less information than the EPGtransmission. The filter in the decoder disregards unwanted or undesirable items, e.g. networks orprogrammes of certain types.full EPG: A Multiple Channels EPG which, as a broadcast type includes navigation and sortinginformation, or as a decoder type makes use of such information if it is available.SIST ETS 300 707 E1:2003

The nature of an EPG as a database stored in aproduct and accessed by the user via on screen menus is also introduced. To accommodate the widerange of products and broadcasts possible with such a system the idea of "Types of EPG" is introduced.-Presentation Techniques:The image seen by the user is crucial to the success of the EPG. The menus and screen layouts are veryfar removed from the traditional image of Teletext. In short the product is now responsible for the menuson the screen layout. The user will be able to perform interactively with these menus. It is essential thatthe information provider be aware of possible screen layouts to ensure that the information is displayed ina pleasing and correct way. Therefore this clause outlines a "code-of-practice" between TV setmanufacturer and information provider on "how the information will look".-Installation and Consistency:Care needs to be taken to ensure that products can handle the volume of data efficiently and accurately.Also products will probably be able only to handle one Full EPG; however more than one may be availableso how to choose the right one is important.-Scheduling:The parties involved in providing a TV Guide need flexible and efficient means to modify (delete, insert,alter) data already stored in the receiver's EPG database.-The Data Groups (clauses 8 to 11):Now that the functions and requirements of the TV Guide have been listed the required data is groupedtogether in functional blocks, and the detailed encoding and numbering of the data takes place.NOTE:This ETS is independent of the transport layer (according to OSI layers). EPG data willbe broadcast via a Teletext data channel. The actual transportation system is laiddown in ETS 300 708 [1].4.2How does an EPG benefit a TV / VCR userIn the era of cable / satellite TV a user can expect to receive maybe 30 channels offering perhaps morethan 1 000 programmes per day. A system to allow the user to quickly and efficiently find the programmeSIST ETS 300 707 E1:2003
Page 12ETS 300 707: May 1997of his choice is becoming ever more attractive. While history has shown that paper can be a very usefulmedium to convey programme information, simply giving information is no longer enough.The value of an EPG to a user is to be informed of the most interesting programmes that fit his viewingcriteria. Now the user can see if a programme of his choice is available within the next few days and onwhat channel. Or, the user can select to be informed of the best programmes by means of the rating aninformation provider has associated with the programme data. Similar attributes such as the language ofthe programme, its subtitles and audio description or the indication of the unsuitability of the programmefor viewing by children can be included.Integration into the products will also support more comfortable ways of interacting with the devices -e.g. VCRs can be programmed (also for VPS / PDC) by "point-and-click" paradigms rather thancomplicated manipulation of cryptic keys.It has also been an additional goal to define a protocol that is able to allow a TV or VCR with currentanalogue signals to have a comparable functionality and those planned with DVB. Future products willstrive to minimize the differences between signals coming from an analogue source and those from adigital one when presenting information to the user.The EPG provides the functionality required by the viewer to select the programmes that are to be viewedand providing an easy route to transfer this information to the TV set or Video recorder by:-"storing" the data as a database in the TV set or VCR;-"separating" the way the information is presented or displayed from the way in which the data istransmitted;-allowing the viewer to selectively sort and store information according to h
