Summary - J.1113 (12/2025) - Specification for IP-based digital video convergence service

As digital broadcasting services are being rapidly deployed, many service operators are considering more effective transmission of these services. Recently, digital broadcasting services have evolved and are using resources more efficiently to more easily accommodate the varying needs and environments of subscribers. Therefore, it is necessary to redefine Internet protocol (IP)-based digital video convergence service (DVCS) for maintaining quality of service (QoS) and using bandwidth effectively for transmission on broadband network environments.
IP-based DVCS is a service system for distributing digital video via IP-based broadband networks. It is the service system for providing interfaces and functionalities to enable service operators to offer QoS-guaranteed broadcasting to subscribers via IP-based converged broadband networks.
Recommendation ITU-T J.1113 defines the specification of IP-based DVCS, considering the convergence environment. It defines the specification of IP-based DVCS including IP-based switched d4gital video (SDV) technologies considering the convergence environment. It is based on Recommendation ITU-T J.1111 "Requirements for the advanced IP-based digital video convergence service" and Recommendation ITU-T J.1112 "Functional requirements for IP-based digital video convergence service".
