摘要： In one embodiment, a receiver for a frame of media packets employing the real-time transmission protocol (RTP) and forward error correction (FEC) is disclosed. The receiver comprises a packet buffer and an FEC decoder. After a packet is received by the packet buffer, the FEC decoder reads the packet and, as part of FEC processing, performs an XOR operation on the packet, without waiting for the entire frame (or, indeed, for any subsequent packet of the frame) to be received. The XOR operation results are accumulated until sufficient packets are received to reconstruct a missing packet in the frame. Because the XOR operations are performed immediately after a packet is received, without any delay from waiting for subsequent packets, the receiver has a very low latency, and the packet buffer may be relatively small.
摘要翻译：在一个实施例中，公开了一种采用实时传输协议（RTP）和前向纠错（FEC）的媒体分组帧的接收机。接收机包括分组缓冲器和FEC解码器。在分组缓冲器接收到分组之后，FEC解码器读取分组，并且作为FEC处理的一部分，在分组上执行XOR操作，而不等待整个帧（或实际上，对于帧的任何后续分组））被接收。积累XOR运算结果，直到接收到足够的数据包来重构帧中丢失的数据包。由于在接收到分组之后立即执行XOR操作，所以接收机没有等待后续分组的任何延迟，所以接收机具有非常低的延迟，并且分组缓冲器可能相对较小。

摘要： A communication system transmitter comprises an adaptive error correction encoder. The adaptive error correction encoder is configured to generate a plurality of error correction frames with each such error correction frame comprising a plurality of data packets and one or more error correction packets. A given one of the error correction packets comprises information relating to the plurality of data packets of its corresponding frame and additional information relating to a different one of the error correction frames. The additional information may be inserted into a header of the given error correction packet, and may comprise a next frame sequence number indicator and a corresponding next frame mask value for a subsequent one of the error correction frames. Other aspects of the invention relate to a communication system receiver comprising an adaptive FEC decoder, adaptive FEC encoding and decoding methods, integrated circuits, and associated computer program products.

摘要： An attacker is prevented from obtaining information about the configuration of a computer system. Each of one or more revealing content elements that may be found in outgoing data transmitted by the computer system and that are capable of being used by the attacker to obtain the information about the configuration of the computer system is associated with one or more respective replacement content elements. Outgoing data to be transmitted by the computer system are then scanned for these one or more revealing content elements. A revealing content element found in the outgoing data is replaced by a replacement content element from the one or more replacement content elements associated with that revealing content element. This is done before the outgoing data is transmitted.
