39、 Information. They are commonly carried via the same technical means, hence the confusion, but their uses and requirements are different and require to be analysed. 4.1 Electronic Programme Guides Programme guides provide users of television, radio, and other media applications with continuously upd
40、ated information displaying scheduling information for current and upcoming programming. Traditionally, these were print publications. The Radio Times debuted as early as 1923. It originally carried details of the BBCTMradio programmes. Initially newspapers boycotted radio listings because they fear
41、ed that people would listen to news on the radio instead of buying newspapers. Today most newspapers carry a selection of daily television and radio programming. With the rapidly increasing spread of television receivers beginning in the 1960s, electronic versions of programme information were made
42、available to viewers. They provide viewers with continuously updated on-screen menus displaying scheduling information. Their technological development happened in three phases: Teletext first made programme information available to viewers, when the BBCTMs Ceefax system debuted in 1976. The first T
43、V sets with integrated decoders came to the market in 1977. Today, Teletext i.1 is still the main source of electronic programme information for most viewers, notably in the less developed countries. Figure 1: Ceefax programme information from 1983 Non-interactive electronic programme guides (EPG) a
44、re typically available for television and radio, and consist of a digitally-displayed, non-interactive menu of program scheduling information shown by a cable or satellite TV provider to its viewers on a dedicated channel; much like an airport display. They were first introduced in 1981 in North Ame
45、rica, and this is where the term “EPG“ was coined. ETSI ETSI TR 102 988 V1.1.1 (2011-05) 9Figure 2: Electronic programme guide (EPG) from 1987 Interactive electronic programme guides (IPG) - though often referred to as EPG - allow television viewers and radio listeners since the early 1990s to navig
46、ate scheduling information menus interactively. Selecting and discovering programming by time, title, station, or genre is managed through an input device such as a keypad, computer keyboard, or TV remote control. Its interactive menus are generated entirely within local receiving or display equipme
47、nt using raw scheduling data sent by individual broadcast stations or centralized scheduling information providers. Figure 3: Interactive programme guide (IPG) from 2011 Nowadays, IPGs are more and more available on the Internet, either from sites specialized in programme information (sometimes affi
48、liated to print publications), or directly from the television channel itself. ETSI ETSI TR 102 988 V1.1.1 (2011-05) 104.2 Presentation techniques Already in 1997, ETS 300 707 i.2 suggested partitioning of the programme information into vies that relate to proximity in both, time and space: This Cha

There are many technical and organisational obstacles for pushing these updates to the consumers. There are large variations of the frequency of consumer-level EPG updates between markets and even within markets. Frequent updates present a challenge for EPG aggregators, because they make high-quality editorial work virtually impossible. Also, programme cancellation is
