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: Error flags are generated for use in source decoding of a source-coded bit stream transmitted through a channel of a communication system. The source-coded bit stream is channel coded using at least one channel code, and the channel code is decoded in a soft-decision channel decoder to generate a received version of the source-coded bit stream and one or more reliability measures associated with a designated portion of the received version of the source-coded bit stream. The reliability measures are processed to generate one or more error flags indicative of the presence of an error in the corresponding portion of the received version of the source-coded bit stream. The invention allows different detection capabilities to be used for different portions of the received version of the source-coded bit stream, and further allows these detection capabilities to be changed dynamically at the receiver. The error flags may be used to trigger an error mitigation/concealment algorithm in the source decoder. Advantageously, the error flags can be matched to frames or subframes of the source-coded bit stream, such that the performance of the error mitigation/concealment algorithm is substantially improved relative to its performance when using error flags generated from a conventional outer block code.

Abstract translation: 生成错误标志用于通过通信系统的通道发送的源编码比特流的源解码。 源编码比特流使用至少一个信道码进行信道编码，并且在软判决信道解码器中解码信道码，以产生源编码比特流的接收版本和与 源编码比特流的接收版本的指定部分。 处理可靠性度量以产生指示在源编码比特流的接收版本的对应部分中存在错误的一个或多个错误标志。 本发明允许将不同的检测能力用于源编码比特流的接收版本的不同部分，并且还允许在接收机处动态地改变这些检测能力。 错误标志可用于触发源解码器中的错误减轻/隐藏算法。 有利地，错误标志可以与源编码比特流的帧或子帧匹配，使得当使用从常规外部块码产生的错误标志时，相对于其性能，误差减轻/隐藏算法的性能被显着改善。

Abstract: A wireless relay system (1) comprises a wireless camera (11) and a reception relay station (12). The reception relay station (12) comprises a plurality of external reception units (13) arranged at spatially different positions and an internal reception unit (14). Each reception section (16) in the internal reception unit (14) demodulates a signal received in the external reception unit (13) and outputs a transport stream. At this time, each reception section (16) sets an error indicator flag to 1 for a TS packet causing a transmission error which exceeds the error correction capability. A TS synthesizer section (17) in the internal reception unit (14) completely synchronizes a plurality of input transport streams by referencing synchronization bytes, PID, and CC values, and selects to output a TS packet having the error indicator flag not set to 1.

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. Particular classification operations performed by at least one of the first and second classification circuitry are programmable via software that may be supplied to the processor via an associated host device. The processor may be configured as a network processor integrated circuit to provide an interface between a network and a switch fabric in a router or switch.

Abstract: Transmission units such as packets of coded data are received in a transmission layer, converted to coding units, supplied to a coding layer, and decoded in the coding layer. Errors in arriving transmission units are detected in the transmission layer. The results of error detection in the transmission layer are used when the coding units are decoded in the coding layer, preferably by having the transmission layer provide the coding layer with error information explicitly indicating which of the coding units are free of errors and which are not.

Abstract: Frame quality information is transmitted and updated within a core network (CN) and a RAN downlink to UE. In the CN, CRC checks are done and the FQC field is set according to the results of the CRC check and the received FQC field's value, and transferred to the next node in the communication path. A server, or servers, instruct(s) MGWs and RNCs within the communications path to apply CRC checks and generate the FQC field according to the received FQC field and the applied CRC check. The lu framing protocol is used to transfer the FQC between the CN and RNC. A radio protocol, such as RRC protocol, is used between the RNC and the mobile to transport the FQC field in the downlink to the UE. Within the CN, the FQC field is transported over the Nb interface

Abstract: A receiver including an error masking unit for masking an error in a digital signal received by the receiver, and a transmission system including such a receiver. The transmission system includes a transmitter which sub-band codes a wide-band digital signal into sub-band signals having signal blocks containing a predetermined number of samples which the transmitter quantizes and combines with bit allocation information denoting how many bits each of the samples in the signal blocks are quantized by and scale factor information relating to scale factors for the signal blocks into a digital signal. That digital signal is error correction encoded and then applied to a transmission medium by the transmitter. The receiver receives a digital signal from the transmission medium which substantially corresponds to the digital signal applied to the transmission system by the transmitter and decodes that digital signal so as to produce a replica of the wide-band digital signal encoded by the transmitter. The error masking unit is used during decoding for error masking information having uncorrected errors. The error masking unit is capable of masking an uncorrected error pertaining to the quantized samples, the bit allocation information, the scale factor information and/or sync information included in the digital signal received by the receiver.
