scope:

This Recommendation describes some methods by which measurement information of IPTV service quality can be used to dynamically control the performance of an IPTV service such as network resource allocation, FEC redundant encoding, delivery path selection or media encoding bit rate if scalable encoding is employed.

This Recommendation defines the subset of QoS/QoE performance parameters to be obtained from the IPTV monitoring system and methods for analysing them to provide media resource and transport network resource control in support of high quality end-to-end delivery of IPTV services.

It also provides guidance on the collaboration between different providers and defines the metrics to be exchanged between them for resource management.
