Abstract: A method and an apparatus using a system level clocking scheme to remove jitter from multi-media packets distributed over an asynchronous network. The present invention overcomes the problems associated with jitter introduced in an asynchronous network by using various time stamps to synchronize a client device clock to a headend clock and to control the data flow in the client device to match the rate that the data is received by a broadband receiver coupled to the headend. The present invention allows the client device to synchronize to a selected one of a plurality of headend clock by including a clock adjustment factor along with the time stamps. The time stamps are added at the physical layer so that the time stamps correspond to the time the data packets are placed onto and received from the asynchronous network.

Abstract: A Bluetooth module that corrects real-time data contains a synchronous connection-oriented link, a memory, and a signal correcting circuit. The signal correcting unit circuit receives packets of audio data from the synchronous connection-oriented link. When a failed packet has been determined, the signal correcting unit circuit determines the similarity between the data in the packets received before and after the failed packet and the data in two of the packets received before the failed packet with one packet therebetween to obtain two-packet data having similarity to the data in the packets received before and after the failed packet. The signal correcting unit circuit then interpolates the packet data between the obtained two-packet data in place of the data in the failed packet.

Abstract: A decoding method and an apparatus operate by performing error correction on code words of an error correcting code block in one direction selected from a row direction and a column direction, indicating in error flags the remaining code words except at least some code words from code words having uncorrectable errors, and performing error correction on code words in the other direction based on the error flags. Accordingly, errors that have been conventionally considered as being uncorrectable may now be corrected.

Abstract: A fault region identification system adapted for use in a network, such as a storage area network (SAN), includes logic and/or program modules configured to identify errors that occur in the transmission of command, data and response packets between at least one host, switches and target devices on the network. The system maintains a count at each of a plurality of packet-receiving components of the network, the count indicating a number of CRC or other errors that have been detected by each component. The error counts are stored with the time of detection. The system alters the EOF (end-of-file) delimiter for each packet for which an error was counted such that other components ignore that packet, i.e. do not increment their error counts for that packet. Link segments adjacent single- or multiple-device components of the network are identified as fault regions, based upon the error counts of those components.
