Summary

This Recommendation defines protocols between a server and a client in order to distribute sound and television programs by J.120, i.e. perform "webcasting", over a general IP network, which is a non-QoS guaranteed network where data error or packet losses may occur. The use of these protocols results in an improvement of quality.

A scheme is provided wherein a quality report is sent from a client to the server, and the server performs optimum data distributions according to the client's report.

This Recommendation defines the kinds of parameters that a client should report to the server, as well as a transmission protocol that is used for sending the report from the client to the server. This Recommendation also defines transmission of supporting parameters that are useful for the server to analyze the client's report.
