Summary - J.1114 (12/2025) - General requirements for IP-based smart digital audio services

As digital broadcasting services have been deployed rapidly, service providers have been considering more effective services accommodating diverse needs of users, such as further efficiency of transmission resources, use of latest coding technologies, interoperability with various IP-based networks, metadata and auxiliary services.
Recommendation ITU-T J.1114 describes the requirements of IP-based smart digital audio services. For providing IP-based smart digital audio services using broadband and broadcasting networks, some requirements need to be considered: transmission and coding efficiency, bit rates and IP-based transport packaging for interoperability.
Recommendation ITU-T J.1114 is Part 1 of a multi-part deliverable composed of the following three parts:
Part 1: Requirements for IP-based smart digital audio services;
Part 2: Functional requirements for IP-based smart digital audio services (published as ITU-T J.1115);
Part 3: Specifications for IP-based smart digital audio services (to be published as ITU-T J.1116).
