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： The invention relates to a method for packet switched streaming of media, such as video and/or audio, from a streaming server (111) to a mobile client device (101) over an air-interface. The method comprises noticing a change in a downlink air-interface bandwidth, sending from the mobile client device (101) to the streaming server (111) a request for adapting streaming server transmission bit rate, receiving the request at the streaming server (111) and adapting the streaming server transmission bit rate in accordance with the request. According to the method, the request indicates to the streaming server (111) a current downlink air-interface bandwidth and that said adapting of the streaming server transmission bit rate is performed in accordance with said current downlink air-interface bandwidth.

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： The present invention relates to a method for transmitting video information, in which a bitstream is formed comprising a set of frames comprising macroblocks. At least one switching frame is formed into the bitstream, macroblocks of the switching frame are arranged into a first and a second group of macroblocks, each macroblock of the first group of macroblocks are encoded by a first encoding method to provide a switching point for continuing the transmission of video information with another bitstream formed from the video information; and macroblocks of the second group of macroblocks are encoded by another encoding method. Errors in transmission of video information are reduced by forming at least one SP-encoded frame by predictively encoding the macroblocks; replacing part of the SP-encoded macroblocks with intra encoded blocks; and transmitting the encoded frame containing both predictively and intra encoded macroblocks instead of the SP-encoded frame.
