摘要： A method and system for adaptively controlling level of a receiver buffer in a client in a multimedia streaming network. The multimedia streaming network has a server for providing streaming data to the client. The server is responsible for adapting the transmission rate to the reception rate or congestion control, and for adapting the sampling rate to the transmission rate. Thus, the server manages the shift and keeps it within the rate adaptation operating range. The client is responsible for compensating for the packet transfer delay variation, which is also known as network jitter. The client is also responsible for setting parameters of the server rate adaptation operating range. The client chooses and sends the shift parameters to the server, but it is up to the server to adapt its encoding rate or transmission rate when responding to the parameters.

摘要： A method for the client in a multimedia streaming network to control the receiver buffer fullness by way of effectively shifting the transmission clock in the server who provides streaming data to the client. In order to avoid buffer underflow or overflow, the client sends a message to the server requesting the shift of the transmission clock either forward or backward depending on whether the client wants to increase or decrease the receiver buffer. Based on the message, the server adjusts the data transmission amount by effectively shifting its transmission clock. The request from the client can be sent through RTCP or RTSP.

摘要： A method, system, device, and computer code product is disclosed in which a sender transmits data to a plurality of receivers via a point-to-multipoint session. The receiver sends data repair requests to the sender requesting data expected but not received and the sender retransmits the expected but not received data via the point-to-multipoint session. The sender can also schedule point-to-point data repair sessions with individual receivers if the retransmission via the point-to-multipoint session does not correct all errors. The sender can be configured to delay point-to-point repair sessions using a randomization mechanism based on the number of receivers using the point-to-multipoint session.

摘要： A method to provide to a sender of RTP packets the actual receiver buffer fullness level in a receiver of the RTP packets at a certain time instant represented as remaining playout duration in time. The receiver sends in an RTCP report the sequence number of a selected RTP packet in the receiver buffer and the time difference between the scheduled playout time of this packet and the current time. Based on this timing information, the sender calculates the amount of time it would take for the receiver buffer to empty if the receiver continues to playout at normal speed and no further RTP packets arrive to the receiver buffer. This receiver buffer fullness level information can be used at the sender to adjust the transmission rate and/or nominal playout rate of the RTP packets in order to maintain a targeted receiver buffer fullness level.
摘要翻译：向RTP分组的发送者提供RTP分组的接收机中的实时接收机缓冲器满量级的方法，该接收器在特定时刻即时表示为剩余播出持续时间。接收器在RTCP报告中发送接收缓冲器中选定的RTP分组的序列号以及该分组的预定播放时间与当前时间之间的时间差。基于该定时信息，如果接收机以正常速度继续播放并且没有其他RTP分组到达接收机缓冲器，则发送器计算接收器缓冲器将要花费的时间量。可以在发送器处使用该接收器缓冲器充满度级别信息来调整RTP分组的传输速率和/或标称播放速率，以便维持目标接收机缓冲器充满水平。
