Electronic Programme Guide (EPG) - Protocol for a TV Guide using electronic data transmission

This specification establishes a technical framework for the exchange of electronic program guide data within television broadcasting systems. It defines the necessary protocols for integrating digital data services with traditional TV signals, enabling viewers to access schedules, descriptions, and supplementary information directly through their reception equipment. The document outlines specific data structures and transmission methods required to ensure interoperability between different broadcast systems and receiving devices. It addresses the synchronization of program metadata with audio-visual content, facilitating a seamless user experience for information retrieval. The scope covers the signaling mechanisms used to initiate data reception and the format in which service information is encoded. By providing a unified approach to managing electronic data within the broadcast stream, this standard supports the evolution of teletext and data services in television environments. It serves as a reference for manufacturers and broadcasters developing compatible hardware and software solutions for enhanced television functionality.
