REAL TIME - RELAY CAST STREAMING PROTOCOL, RT-RCSP

摘要

A real-time relay cast streaming protocol is provided to enable quality differentiation of services according to requirements of users and to perform an effective performance maintenance function based on organic information exchanging and active decision between a server and a client. Clients(004-007) are able to relay(009-011) self-received multimedia data to other clients(005-007) according to ranks. The ranks of the clients are divided into 4 types. When the ranks are classified by a physical distance between a server and the clients and a logical distance including states of transmission lines, the best classified rank is defined as the first rank client, and a relatively stable but not good as the first rank is defined as the second rank client.
