摘要： In an audio network system constructed from a main node and a plurality of satellite nodes each having a plurality of ports, the main node generates and transmits a main packet including audio signals of a plurality of channels. Each satellite node selects one of the plurality of ports in turn, and confirms whether the main packet arrives at the selected port every predetermined period or not. When the main packet arrives at the selected port every predetermined period, the main packet is received via the port by continuing selection of the port. In the case where reception of the main packet is lost, one is selected from the plurality of ports in turn, the operation to confirm arrival of the main packet is restarted, and another port at which the main packet arrives at the present stage is automatically found.

摘要： A processing apparatus includes a network of interconnected processors comprising a plurality of signal processors for digitally processing input signals in real time to generate output signals and one or more control processors, each control processor controlling the operation of a plurality of signal processors. The processing apparatus automatically schedules control tasks in a plurality of time slices, where more than one control processor is provided for coordination between control processors, a wired-OR configuration connection can be provided to synchronise the beginning and/or end of the time slices. A control processor can change an address field of microcode instructions of a signal processor for implementing a multiplexer function. A control delay list can be provided for scheduling control task delays. Control tasks can be allocated to more than one control processor, each control processor then communicating to the other control processors if it completes the task so that the other control processors may abandon further processing of the task.

摘要： An analog-to-digital conversion arrangement converting an input analog signal into an output digital representation. Two or more analog-to-digital conversion paths each applying a conversion mapping between input analog signal magnitudes and respective digital values generate an intermediate representation of the input analog signal, the conversion paths being operable to apply different respective conversion mappings. An output circuit combines the intermediate representations from at least two conversion paths to generate the output digital representation, the intermediate representations being combined according to a weighting dependent on the magnitude of the input analog signal. At least one of the conversion paths has an enhanced sensitivity mode appropriate to a range of magnitudes of the input signal that are below a threshold magnitude. Control logic inhibits operation in the enhanced sensitivity mode if the magnitude of the input analog signal exceeds the threshold magnitude.
