Abstract

An information acquisition system for acquiring information which includes responses in answer to questions which participants have been asked by a radio or television broadcast program includes terminal equipment for inputting a response from a participant, an ATM network for transmitting, to a broadcasting station, information which includes the response inputted from the terminal equipment, network terminating equipment provided in the broadcasting station and connected to a predetermined ATM exchange in the ATM network, and an information acquisition unit, which is connected to the network terminating equipment, for receiving, collecting and totalizing the information, which includes the response inputted from the terminal equipment, via the ATM network and the network terminating equipment.

Claims

1. An information acquisition system for acquiring information which includes responses to questions which participants have been asked by broadcast program, comprising:

a plurality of terminal equipment for inputting responses from unspecified audiences of a predetermined broadcast program;

an ATM (Asynchronous Transfer Mode) network connected to said plurality of terminal equipment and receiving information including responses from unspecified audiences of said broadcast program and transmitting said information to a broadcasting station, said information including a response inputted from a predetermined terminal equipment of a participant of said broadcast program;

network terminating equipment provided in the broadcasting station and connected to a predetermined ATM exchange in said ATM network; and

an information acquisition unit, which is connected to said network terminating equipment, for receiving and collecting, via said ATM network and said network terminating equipment, information from unspecified audiences of said broadcast program, said information including the response inputted from said predetermined terminal equipment,

wherein when said predetermined terminal equipment calls the broadcasting station, said ATM network performs call control to decide a path between said terminal equipment and the broadcasting station and designates different virtual channel identifiers for said terminal equipment and said broadcasting station,

said terminal equipment produces a data cell by adding the virtual channel identifier designated by said ATM network to the information which includes the response to the question, and sends the data cell produced to said ATM network,

said ATM network sends the data cell via said path to the ATM exchange to which the network termination equipment of the broadcasting station has been connected, and

said ATM exchange replaces the virtual channel identifier that has been added to the data cell by the virtual channel identifier that has been designated for said broadcasting station, and sends this data cell to said network terminating equipment; and

wherein, when a call is made at said predetermined terminal equipment, said terminal equipment produces a signal cell by adding a special virtual channel identifier determined for a call to information which includes an originating number and a terminating number, and sends said signal cell to said ATM network,

said ATM network performs the call control in response to reception of the signal cell and, prior to sending of a data cell, said ATM exchange as a terminating exchange produces a signal cell by adding a special virtual channel identifier determined for termination to information which includes a virtual channel identifier, designated for the broadcasting station, as well as the originating number, and sends said signal cell to the network terminating equipment of the broadcasting station, and

said network terminating equipment receives said signal cell and stores the correspondence between the virtual channel identifier and the originating number; and

wherein said network terminating equipment includes;

a cell distributor for identifying an incoming cell from said ATM network as being a data cell or a signal cell, distributing the data cell to said information acquisition unit and distributing the signal cell to a signal assembling circuit, which is a subsequent stage;

the signal assembling circuit which, when the incoming cell is a signal cell, is for assembling information contained in said signal cell;

a call controller which, in a case where said information contains an incoming message, sends an answer cell back to the terminating exchange and, upon reception of the data cell, sends back a call-disconnect cell; and

means for preserving the correspondence between the virtual channel identifier and the originating number contained in the assembled information.

2. The information acquisition system according to claim 1, wherein said information acquisition unit comprises:

identifying means which, when the data cell is received, is for identifying the virtual channel identifier contained in said data cell;

memory means for storing response data, which is contained in said data cell, in correlation with the virtual channel identifier; and

totalizing means for analyzing and totalizing the response data stored in said memory means.

3. The information acquisition system according to claim 2, wherein said information acquisition unit correlates and stores the originating number and the response data by using a correlation between the virtual channel identifier and the originating number as well as a correlation between the virtual channel identifier and the response data.

4. The information acquisition system according to claim 2, wherein when the response data contains gender or place of residence, said information acquisition unit analyzes and totalizes responses by gender or by place of residence.

5. An information acquisition system for acquiring information which includes responses to questions from unspecified audiences which have been asked by broadcast program, comprising:

an information acquisition unit for receiving and collecting information which includes the responses from unspecified audiences of a predetermined broadcasting program, said information acquisition unit being connected to a network terminal equipment which transmits a response to said information acquisition unit as a data cell,

wherein said information acquisition unit comprises;

identifying means which, when an incoming data cell is received from said network terminal equipment, is for identifying a virtual channel identifier contained in said data cell;

memory means for storing response data, which is contained in said data cell, in correlation with the virtual channel identifier; and

totalizing means for analyzing and totalizing the response data stored in said memory means.

6. The information acquisition system according to claim 5, wherein said information acquisition unit correlates and stores an originating number and the response data by using a correlation between the virtual channel identifier and the originating number as well as a correlation between the virtual channel identifier and the response data.

7. The information acquisition system according to claim 5, wherein when the response data contains gender or place of residence, said information acquisition unit analyzes and totalizes responses by gender or by place of residence.

8. An information acquisition system for acquiring information including responses to questions from any participants of a broadcast program, comprising:

terminal means for transmitting a response from a participant of the broadcast program;

information acquiring means; and

ATM (Asynchronous Transfer Mode) network means for establishing a communication channel between said terminal means and said information acquiring means and for transmitting the response to said information acquiring means;

said information acquiring means including identifying means which, when a data cell is received therein, identifies a virtual channel identifier contained in said data cell;

memory means for storing response data from said participant, which is contained in said data cell, in correlation with the virtual channel identifier; and

totalizing means for analyzing and totalizing the response data stored in said memory means.

9. The information acquisition system according to claim 8, and further comprising a network terminating equipment provided in a broadcast station and connected to said ATM network means, wherein said network terminating equipment includes:

a cell distributor for identifying an incoming cell from said ATM network as being a data cell or a signal cell, distributing the data cell to said information acquiring means and distributing the signal cell to a signal assembling circuit, which is a subsequent stage;

the signal assembling circuit which, when the incoming cell is a signal cell, is for assembling information contained in said signal cell;

a call controller which, in a case where said information contains an incoming message, sends an answer call back to the ATM network means and, upon reception of the data cell, sends back a call-disconnect cell; and

means for preserving the correspondence between the virtual channel identifier and the originating number contained in the assembled information.

10. The information acquisition system according to claim 8, wherein when a call is made, said terminal means produces a signal cell by adding a special virtual channel identifier determined for a call to information which includes an originating number and a terminating number, and sends said signal cell to said ATM network means;

said ATM network means performs a call control in response to reception of the signal cell and, prior to sending of the data cell, produces a signal cell by adding a special virtual channel identifier determined for termination to information which includes said virtual channel identifier, designated for a broadcasting station, as well as the originating number, and sends said signal cell to the broadcasting station; and

the broadcasting station receives said signal cell and stores the correspondence between the virtual channel identifier and the originating number.
