The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62514:2024 describes the general guidelines for typical applications of the home multimedia gateway in home networks supporting IP networking. This document specifies recommended functions and services to be supported by the home multimedia gateway and, where appropriate, refers to existing standards supported in the market. For general requirements, it is expected that widely adopted standards and technologies will be considered by implementers. This document gives supplementary applications to the IEC 62481 series, which specifies a central management model in home networks supporting various interfaces on the LAN side and on the WAN side (optional). This document is applicable to home multimedia gateways in the home network or networks of similar environments. IEC 62514:2024 cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of new multimedia processing functions and requirements the HMG shall support, including adaptive multimedia processing, audio/video remote processing, and play function enhancement, in Clause 6; b) addition of home automation functions and requirements of audio/video analysis, recognition and alarm services based on AI technologies in Clause 7; c) addition of upgrade function and requirements of HMG in Clause 12.
