Abstract
Abstract A sound transmission method is carried out in a data way system comprising at least one controller, more than two data input modules and more than two data output modules all of which are connected to one another by a series of data transmission lines making a single loop while linking them together. The data input modules and output modules each are given an address. One or some of the data input modules are constructed as a sound input module or modules, while one or some of the data output modules are constructed as a sound output module or modules. The controller specifies the addresses of the sound input and output modules more frequently than those of the other data input and output modules.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
218 words
A method of effecting a data way system comprising (i) interconnecting with data transmission lines at least one controller, more than two data input modules and more than two data output modules to form a loop, each said module having a single address assigned thereto in advance, said controller being adapted to specify the address of any one of said data input modules to input a data into the loop, at least one of said data input modules including a sound-to-electricity converter such as a microphone, a low-pass filter circuit and an analog-to-digital converting circuit so as to provide a second input module, and at least one of said data output modules including a digital-to-analog converting circuit and an electricity-to-sound converter so as to provide a cound output module, and (ii) causing said controller to address a said sound input module for causing said sound input module to put data representative of sound into the loop, and to address a said sound output module for causing said sound output module to convert data from the loop into a sound output, and to address said sound input module and said sound output module at a frequency greater than said other data input and output modules so that said system relays sound and data between selected said modules with fidelity.
Claim 2
Independent Claim
218 words
A method of effecting a data way system comprising (i) interconnecting with data transmission lines at least one controller, more than two data input modules and more than two data output modules to form a loop, each said module having a single address assigned thereto in advance, said controller being adapted to specify the address of any one of said data input modules to input a data into the loop, at least one of said data input modules including a sound-to-electricity converter such as a microphone, a low-pass filter circuit and an analog-to-digital converting circuit so as to provide a second input module, and at least one of said data output modules including a digital-to-analog converting circuit and an electricity-to-sound converter so as to provide a cound output module, and (ii) causing said controller to address a said sound input module for causing said sound input module to put data representative of sound into the loop, and to address a said sound output module for causing said sound output module to convert data from the loop into a sound output, and to address said sound input module and said sound output module at a frequency greater than said other data input and output modules so that said system relays sound and data between selected said modules with fidelity.
Claim 3
Dependent Claim
40 words
The method of claim 1, wherein the data way system has a characteristic message transmission frequency A and includes n different addresses of sound modules, and wherein step (ii) includes addressing each sound module at a rate greater than A/(n+1).
Claim 4
Dependent Claim
48 words
The method of claim 1, wherein the data way system has a characteristic message transmission frequency A and includes n different addresses of sond modules and m non-sound data modules, and wherein step (ii) includes addressing each said non-sound data module at a rate not more than A/nm.
Claim 5
Dependent Claim
62 words
The method of claim 1, wherein the data way sytem has a characteristic message transmission frequency A, and wherein step (ii) includes addressing each said sound module at a fixed frequency A/(n+1) and addressing each non-sound module at a second rate which is a divisor of said first rate, where n is the number of addresses of sound modules in said system.
Claim 6
Dependent Claim
34 words
The method of claim 1, wherein step (ii) includes the step of addressing a second module with a frequency which is substantially an integral multiple of the frequency for addressing a non-sound data module.
