Abstract: A vehicle active network (12) communicatively couples devices (14-20) within a vehicle (10). Device operation is independent of the interface (22-28) of the device (14-20) with the active network (12). Additionally, the architecture of the active network (12) provides one or more levels of communication redundancy. The architecture provides for the total integration of vehicle systems and functions, and permits plug-and-play device integration and upgradeability.

Abstract: A network processor or other type of processor includes first classification circuitry, scheduling circuitry and second classification circuitry. The first classification circuitry is configured to determine for a given packet received by the processor whether the packet has one or more errors. The scheduling circuitry in an illustrative embodiment receives an indication of the error determination made by the first classification circuitry, and based on the indication controls the dropping of the given packet from the processor memories if the packet has one or more errors, e.g., via a flush transmit command. The second classification circuitry, which may be implemented as a single classification engine or a set of such engines, may be configured to perform at least one classification operation for the given packet, e.g., if the packet is supplied thereto by the scheduling circuitry.

Abstract: In a low bitrate speech encoding system, encoded bits are strongly protected against errors produced on a transmission path. A decoding side checks the transmission errors using an error check code appended to a convolution decoded output and adjusts the decoding output depending on the results of check of transmission errors. At this time, it is necessary to maintain continuity of speech signals after speech decoding. To this end, a convolution decoder 16 convolution decodes the convolution coded output from the encoding device to provide a convolution decoded output of a crucial bit set with the appended error check code and a bit set excluding the crucial bit set. A CRC code comparator-frame masking unit 15 compares the CRC check code appended to the convolution decoded output from the convolution decoder 16 to the CRC check code computed from the bit group excluding the crucial bit set to adjust the convolution decoded output.

Abstract: Determination of the location of an error condition or a failure includes receiving at a network interface a first framed digital signal from customer premises equipment, and determining whether the first framed digital signal indicates a failure. Overhead bits are modified in the first framed digital signal to generate a second framed digital signal, such that the modification is equivalent to insertion of errors into the first framed digital signal at a bit error ratio (BER) of not greater than a predetermined ratio, if the first framed digital signal indicates a failure. The second framed digital signal is then sent from the network interface in place of the first framed digital signal to indicate that the failure reported by the first framed digital signal is located in the customer premises equipment. Otherwise, if no failure is indicated, the first framed digital signal is transmitted without any modifications.

Abstract: Digital packets, defined by a sync byte and then 130 MPEG2 compressed QPSK signal bytes, from a satellite transponder are reformatted prior to transmission to television receivers in apartments in a building wired to distribute video signals. A side byte between such sync and signal bytes in each packet indicates (a) any QPSK packet uncorrectable error and (b) processing information which allows automatic reconfiguration at the settop box. Additional FEC bytes correct to 8 errors within a MPEG2QPSK packet. The system removes the FEC bytes and reframes the MPEG2QPSK packets into a superpacket by converting a first number of the MPEG2QPSK packets to a second number of MPEG2QAM packets. An added sync byte indicates the beginning of each such MPEG2QAM packet. The system adds side data bytes including any uncorrectable errors in each MPEG2QPSK packet and adds a new, less complicated FEC to each MPEG2QAM packet. The system modulates and upconverts the bytes in each MPEG2QAM packet and passes them through a cable plant constructed to receive modulated QAM bytes (or NTSC signals) which are demodulated at the settop box. The additional FEC bytes correct to 8 errors within a MPEG2QAM packet and are then removed. The superpacket is deframed to obtain the MPEG2QPSK packets. After finding a television channel, the side bytes are processed to determine the frequency location of the other channels in the apartment receivers and the existence of uncorrectable errors. The MPEG2QAM bytes are decompressed and encoded to reproduce the television images in the apartment receivers.

Abstract: A method of communicating between nodes in a network where a node receives a sequence of symbols that will form a packet on a first communications channel and has a planned packet that it would send on a second communications channel. A destination is encoded into an arbitration portion of a header sequence of the packet, the header sequence comprising a sequence of symbols. The transmission on the second communications channel is as per the planned packet, for as long as the symbols of the planned packet match the symbols being received on the first channel. An arbitration decision is made when the symbols do not match, with the node either continuing to send the rest of the planned packet, or the rest of the packet being received on the first communications channel.
