摘要： There is provided a broadcast router that includes a plurality of input cards, a plurality of output cards, at least one programmable device, and a configuration control card. The plurality of input cards input data into the broadcast router. The plurality of output cards output the data from the broadcast router. The configuration control card stores configuration information for configuring the at least one programmable device to perform a first set of functions. The configuration control card is adapted for removal and replacement by at least one other configuration control card that stores other configuration information for configuring the at least one programmable device to perform a second set of functions having a difference from the first set of functions so as to change a functionality of the broadcast router.

摘要： A bi-phase decoder suitable for use in a broadcast router and an associated method for extracting subframes of digital audio data from a stream of digital audio data. Logical circuitry within the bi-phase decoder extracts subframes of the digital audio data by constructing a transition window from an estimated bit time, sampling the stream of digital audio data using a fast clock and applying the sampled stream of digital audio data to the transition window to identify transitions indicative of preambles of the subframes of digital audio data.

摘要： A router, for routing at least one input signal to at least one output, comprises at least one input module and at least one output module. Each of the input and output modules includes at least one clock selector circuit for selecting from among a first and second clock signal, and an oscillator signal, as a common output clock signal for the at least first router, based in part on whether at least one of the first and second clock signals has toggled. The clock selector circuit provides redundancy as well as distribution of clock signals among elements within each module.

摘要： A centrally located stage of a time division multiplex switching network is partitioned into blocks and a separate processor is provided to control each such block. The partition is extended to the edge of the network by having each partition processor control through the network both the network equipment in adjacent stages directly coupled to the controlled block, and a preassigned portion of the remainder of the network out to the edge thereof which can be reached either through such controlled equipment or through similar equipment of other partitions. In addition, translating, scanning, and service functions are advantageously separated out of the partitioned processors and performed by separate processors that communicate through the call switching network with the partition processors and/or the network-edge ports.

摘要： A method for extracting selected time information from a stream of serialized AES digital audio data. A first transition of a first preamble of said stream of serialized AES digital audio data is detected and, upon detection of the transition, a time count initiated. A second transition indicative of a subsequent preamble of said serialized AES digital audio data is subsequently detected and the time count halted. The time separating the first and second transitions is then determined. The separation time, which preferably is determined in the form of a fast clock pulse count, is then transferred to a decoding logic circuit for use in decoding the stream of serialized AES digital audio data.

摘要： A broadcast router includes a router matrix having input and output sides. Coupled to the input side of the router matrix are first and second reference inputs. The first reference input is configured for application of a first reference signal thereto while the second reference input is configured for selective application of either a second reference signal or a redundancy of the first reference signal thereto. The broadcast router further includes N inputs, M outputs and a routing engine, coupled between the N inputs and the M outputs, for applying selected ones of the N inputs to the M outputs. A reference select circuit is coupled between the first and second reference inputs and the routing engine.

摘要： An iterative method of correcting errors in a data block. Bad bytes are first identified using information derived from an 8B/10B decoding of the data block. Within each identified bad byte, suspect bits are subsequently identified using information derived from parity decoding of a row of the data block. Each suspect bit is then classified as either a confirmed error bit or an unconfirmed error bit using information derived from parity decoding of a column of the data block in which the suspect bit is located. Confirmed error bits are then corrected, the parity bits corresponding to the confirmed error bit reset, and the bad byte cleared. The process is then repeated if one or more bad bytes remain in the data block.
摘要翻译：一种纠正数据块错误的迭代方法。首先使用从数据块的8B / 10B解码得到的信息来识别坏字节。在每个识别的坏字节中，随后使用从数据块行的奇偶校验解码得到的信息来识别可疑位。然后，使用从可疑位所在数据块的列的奇偶校验解码得到的信息将每个疑犯位分类为确认的错误位或未确认的错误位。然后校正确认的错误位，与确认的错误位复位相对应的奇偶校验位和坏字节清零。如果数据块中存在一个或多个不良字节，则重复该过程。
