EPGs

An Electronic Program Guide (EPG) is a digital information service that provides scheduling, descriptive metadata and related details for television programs. It is delivered to set‑top boxes, televisions and other digital receivers to help users discover and manage content.

EPG data typically includes the channel name, program title, start time, duration, an overview or synopsis, genre, and content rating. Some guides also show cast, episode number, production year, and thumbnails. Many systems support now/next views or full-day grids to help users plan their viewing.

Delivery and standards: In digital television, EPG information can be generated from broadcast data streams and/or internet sources. In DVB systems, the Event Information Table (EIT) carries program events; in ATSC, PSIP provides program data. External guides and software may use XML-based formats such as XMLTV. Some platforms combine broadcast metadata with online data to enhance accuracy and coverage.

Uses: Users consult the guide to see what is currently on and what is scheduled to air, browse by channel or time, and choose programs to watch. EPG data enables reminders and recordings on DVR-enabled devices and supports search, filters, and genre-based discovery.

Evolution and context: EPG data has evolved from simple text listings to rich metadata that supports interactive grids, advanced search, and hybrid broadcast–broadband solutions. Hybrid approaches may supplement broadcast data with online guides for on-demand content and regional variations.

Limitations: EPGs depend on accurate and timely updates; data coverage can vary by region and channel, and some programs may lack complete metadata. Licensing and rights considerations can affect the availability and detail of guide information.
