Patent number: 8804968Abstract: 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.Type: GrantFiled: March 16, 2012Date of Patent: August 12, 2014Assignee: Yamaha CorporationInventors: Nathan Bentall, Peter Charles Eastty

Patent number: 7884745Abstract: 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.Type: GrantFiled: March 21, 2006Date of Patent: February 8, 2011Assignee: Sony United Kingdom LimitedInventors: Peter Charles Eastty, Nicholas George Tembe
