The present document is intended as a companion document to the full specifications, EN 300 707 [1] and EN 300 708 [2], covering the data format and transmission via Teletext of an Electronic Programme Guide (EPG). It is primarily aimed at EPG/Teletext service providers and network operators with the intention that the specifications are interpreted in a consistent way while recognizing that there are many options available to all the parties involved in creating the total system.

The present document outlines the basic EPG concepts and highlights the key parameters for a successful service. It makes recommendations as to how aspects of the specifications should be implemented and suggests strategies to maximize the transmission efficiency of both normal Teletext and EPG services when they coexist in the same TV channel.

The present document has been revised in the light of the knowledge and experience gained from operating real services with a variety of decoders available. It is anticipated that the operation of enhanced EPG may require a further revision.
