摘要： The invention relates to the generation of error correction data for available data packets 53 and to the reconstruction of missing data packets based on available data packets and available error correction data. In order to enable an efficient error correction, the data packets 53 are distributed at an encoding end to at least one block of data symbols 54, each data symbol 54 being of equal size (steps 403,404). Then all data symbols 54 of a respective block are used in an encoding operation for forming a respective one of at least one error correction symbol 56 for this block (step 405). At a decoding end, received data packets 83 are distributed again to a block of data symbols 84 and missing data packets are reconstructed based on these data symbols 84 and on error correction symbols 86 associated to the block.

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.
摘要翻译：一种用于多媒体流网络中的客户端的方法，用于通过有效地将提供流数据的服务器中的传输时钟转移到客户端来控制接收器缓冲器充满度。为了避免缓冲器下溢或溢出，客户端向服务器发送请求向前或向后移动传输时钟的消息，这取决于客户端是否希望增加或减少接收缓冲区。基于该消息，服务器通过有效地移动其传输时钟来调整数据传输量。来自客户端的请求可以通过RTCP或RTSP发送。
