摘要： PROBLEM TO BE SOLVED: To provide a method, a system, a transmitter, a network element, a receiver and a software application improved for data packet transmission in a system capable of point-to-multipoint transmission.
SOLUTION: One or more data packets are transmitted from a transmitter to one or more receivers, at least at one specific receiver of the receivers, a reception of repair data packets is required, repair information is signaled to a repair server in order to trigger a transmission of the repair data packets, and the repair information comprises information related to the number of transmitted data packets correctly received at the specific receiver. The transmission of data packets may for instance be controlled by file delivery over a unidirectional transport protocol and the signaling of the repair information may for instance be controlled by a hypertext transfer protocol.

摘要： PROBLEM TO BE SOLVED: To improve cooperation between adaptation of the bit rate of a packetized data and retransmission of a data packet. SOLUTION: A data packet is transmitted from a server to a client using a first bit rate. The transmitted data packet is stored in a server buffer. Then, the transmitted data packet is stored in a client buffer. Notification is given of defect information related to defects in the transmitted data packet, during transmission to the server. The server analyzes the defect information of which notification is given and determines whether retransmission of the data packet stored in the server buffer is required. Furthermore, the server is given notification of client buffer information related to the state of the client buffer. The server analyzes the client buffer information and decides whether retransmission of the data packet is required. COPYRIGHT: (C)2010,JPO&INPIT

摘要： A method to provide to a sender (20) of RTP packets the actual receiver (50) buffer (54) 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 (26) 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：在RTP分组的接收机中向RTP分组的发送器（20）提供RTP分组的发送器（20）的方法，该特定时刻在时间上表示为剩余播出持续时间。接收器在RTCP报告（26）中发送接收缓冲器中选定的RTP分组的序列号和该分组的调度播出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 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 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： 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.
