    摘要: In a voice data communication system comprising a switchboard for switching lines, a network, interworking units for interworking a protocol on the network with a protocol for a line switching, and IP extension terminals connected to the interworking units through the network, a switchboard notifies a communication between interworking units to the interworking units when recognizing the communication between the interworking units, which are provided corresponding to each of IP extension terminals, and establish a relay route to the interworking unit according to a notification from the switchboard and establish a voice data packet route to a route between the IP extension terminals through the network by using the relay route in response to a route establishment request from the IP extension terminals accommodated, or when the interworking unit is a single and the notification is received from the switchboard, establish a voice data packet route to a route between the IP extension terminals through the network according to a route establishment request from the IP extension terminal accommodated.

    摘要: By using a high-range sub-band signal, a correction coefficient corresponding to importance of auditory sense is calculated to correct a noise level and generate additional signal information, thereby accurately reflecting the noise level of the sub-band important in the auditory sense. Thus, it is possible to calculate additional signal information reflecting the noise level of the sub-band important in the auditory sense according to importance with a small calculation amount. The calculation amount can further be reduced by using a correction coefficient based on the characteristic of an ordinary audio signal.

    摘要: [Problems] To provide a high-quality audio signal encoding technique by controlling the number of time/frequency groups in a frame.[Means for Solving Problems] An audio encoding device includes: a time group boundary candidate position extraction unit (101) for analyzing a sub-band signal (2001) obtained by frequency-changing an input signal and calculating a candidate position of the time group boundary; a time group quantity generation unit (103) for outputting a maximum value of the time group quantity; a time group selection unit (102) for generating a time group quantity not greater than the maximum time group quantity by using the candidate position; and a frequency group generation unit (104) for generating a frequency group by using the generated time group information. The device generates a time/frequency group accurately reflecting a change of the input signal and performs operations while controlling the number of time/frequency groups in the frame.
