Summary

Recommendation ITU-T H.248.66 provides guidance on mapping real time streaming protocol (RTSP) methods, error/status codes and header fields to ITU-T H.248 protocol information elements, packages and procedures. RTSP is used to control the playout of media resources. A media gateway controller (MGC) may be required to support the RTSP and request an ITU‑T H.248‑controlled media gateway (MG) to playout media resources and provide other associated functionality. Several packages are defined to enhance interoperability between RTSP and ITU‑T H.248, however the functionalities defined in these packages may be used for other applications/services.
