摘要： A method of signaling and negotiation between a client and a server in a multimedia streaming service regarding the adaptation of the data delivery process. In order to make sure that the client supports the adaptation mechanisms or capabilities to be used in data delivery, one of the parties provides information indicating the adaptation mechanism or capability that it supports to the other party. Upon receiving the information, the other party uses well-defined RTSP response to indicate the support of that mechanism or capability. Either the server or the client can initiate the negotiation. The implementation of the signaling and negotiation covers an AVPF usage, RTP Retransmission Playload Format usage, and an SPTP usage in a particular 3G PSS session.

摘要： A method for signaling and negotiation between a resource-limited client and a server in a multimedia streaming service regarding packet data delivery. In order to avoid dropping packets at the client side due to its maximum packet rate capability, the client signals to the server declaring the maximum packet rate capability. This capability can be signaled to the client via a capability exchange mechanism or using a multimedia streaming protocol. The client inserts a parameter indicative of the maximum packet data rate capability in a request sent to server. It is up to the server to take the necessary action and make the packet delivery rate adjustment.

摘要： In a multimedia streaming network where a client has a receiver buffer to store packets received from a server to compensate for difference between data transmission amount by server and data usage amount by client, server should be able to adapt the data transmission rate based on the status of the receiver buffer. For rate adaptation purposes, server reconstructs a list of packets in the receiver buffer based on information provided by client. Information signaled to server is indicative of the next unit to be decoded and the sequence number of the packet to which the next unit to be decoded belongs, or the next packet to be decoded in client, the DON number of the next NAL unit or the sequence number of the packet carrying the next NAL unit to be decoded and the DON indicative of the decoding order of that next NAL unit.

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 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。

摘要： A method used for communicating packets or other information units from a server (11) to a client (15) over a communication path including a packet scheduler (14-1) followed by a bottleneck path (14-2), with the packet scheduler (14-1) having a buffer for holding packets so as not to transmit over the bottleneck path (14-2) at a rate either too high or too low, the method providing that the server (11) communicate to the client (15) the last packet sent to the client (11) and do so via a mechanism by which the sender information is communicated over the bottleneck path (14-2) ahead of substantially all packets already in the buffer. The client (11) then uses the sender information to provide, as needed, information useful in adapting the rate at which the packets arrive at the packet scheduler (14-1).
