Communication system for remote sound monitoring with ambiguous signal processing
First Claim
1. A communication system for monitoring sounds of a first place at a second place remote from the first place through a communication line, the communication system comprising:
- a first communication apparatus that is disposed at the first place and that is equipped with an input section for collecting various sounds generated at the first place containing a first type of sound information which should be monitored and a second type of sound information which should not be monitored, and for converting the collected sounds into a signal capable of conveying the sound information, and a transmission section for transmitting the signal to the second place through the communication line;
a second communication apparatus that is disposed at the second place and that is equipped with a reception section for receiving the signal transmitted from the first place, and an output section for reproducing the sounds from the received signal; and
a signal processing section that is disposed in either of the first place and the second place or interposed therebetween, and that processes the signal for creating ambiguous sound information by masking, trimming or modifying the second type of the sound information, whereby the first type of the sound information is monitored from the reproduced sounds at the second place while the second type of the sound information is not monitored from the reproduced sounds since the second type of the sound information is altered to the ambiguous sound information by the signal processing section.

Abstract
A communication apparatus is disposed at a target place for use in monitoring of sounds. An input section collects various sounds generated at the target place. The collected sounds contain a first type of sound information which should be monitored and a second type of sound information which should not be monitored. The input section converts the collected sounds into a signal capable of conveying the sound information. A signal processing section processes the signal for creating ambiguous sound information by masking, trimming or modifying the second type of the sound information. A transmission section transmits the processed signal to a remote place, where the sounds are reproduced from the transmitted signal and the first type of the sound information is monitored, while the second type of the sound information is not monitored, since the second type of the sound information is altered to the ambiguous sound information.

17. A communication apparatus disposed at a remote place for use in monitoring of sounds generated at a target place through a communication line, the generated sounds containing a first type of sound information which should be monitored and a second type of sound information which should not be monitored, the generated sounds being collected at the target place and converted into a signal capable of conveying the sound information, the communication apparatus comprising:
-
a reception section that receives the signal from the target place through the communication line;
a signal processing section that processes the received signal for creating ambiguous sound information by masking, trimming or modifying the second type of the sound information; and
an output section that reproduces the sounds from the processed signal such that the first type of the sound information is monitored from the produced sounds while the second type of the sound information is not monitored from the reproduced sounds since the second type of the sound information is altered to the ambiguous sound information. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
