EPG stands for Electronic Program Guide, an electronically generated list of content broadcast by channels over a specific period. From a broadcaster’s perspective, it’s essentially a digital timetable for promoting their content. This schedule can span a day, week, month, or even longer, though viewers typically access information for shorter timeframes.
In IPTV (Internet Protocol Television), EPG serves as the central navigation system that allows users to browse available channels and view detailed program information. Unlike traditional TV guides, IPTV EPGs are interactive, allowing users to search, filter, and directly select programs for viewing or recording.
Modern EPG systems in IPTV environments are generated automatically, with broadcasters feeding content lists into the system as XML, HTML, or CSV files. This data is then processed and presented to viewers through an intuitive interface on their screens.
