Constructor Summary

SimpleProxyVideoOutProtocolUnit()
Creates new SimpleproxyVideoProtocolUnitBase

Method Summary

javax.media.protocol.DataSource	beginTx() Returns the DataSource to initialize the player
javax.media.Time	getTime() Requests the time of the presentation, returns null in case of error, and an explanation to the proxy frame.
void	init(ComponentInfo nextComponent, java.io.PrintStream out) This method initializes the protocol unit and if it was successfull it returns the component info of the socket where the proxy is waiting for commands otherwise it returns a null pointer
javax.media.rtp.SessionAddress	joinTx(javax.media.rtp.SessionAddress proxySessionAddress, IMetadata presentationMetadata) Requests the beginning of the session and returns the session address of the server, null in case there was any problem
boolean	leaveTx() Requests the leaving of the session
void	setTime(javax.media.Time t) Requests the setting of the presentation at a certain time
