Abstract

A data broadcast receiving apparatus used in a system is combined with another transmission line such as telephone circuit. By receiving a television broadcast having a data broadcast signal, such as a teletext signal, superposed on the television broadcast signal, in which a first auxiliary information signal contained in the data broadcast signal and a second auxiliary information signal from the other transmission line are extracted, a control procedure is created responsive to the first and second auxiliary information signals, and the data broadcast signal and main information from the other transmission line are processed responsive to the control procedure.

Claims

1. A data broadcast receiving apparatus for receiving a television broadcast signal with a data broadcast signal superposed thereon wherein said data broadcast receiving apparatus is for use with a response server comprising:

a data broadcast decoder unit for extracting the data broadcast signal,

a display unit for displaying at least one of the television broadcast signal or data broadcast signal,

a modem connected to a telephone circuit for receiving information from an online service, and

a control unit for storing at least a respective telephone number of the online service from the data broadcast decoder unit, and dialing the telephone number through the modem to connect the online service with the response server when a user selects the telephone number in response to the online service information received through the modem.

2. A data broadcast receiving apparatus for receiving a television broadcast signal with a data broadcast signal superposed thereon wherein said data broadcast receiving apparatus is for use with a response server comprising:

a data broadcast decoder unit for extracting the data broadcast signal,

a display unit for displaying at least one of the television broadcast signal and the data broadcast signal, and

a modem connected to a telephone circuit,

wherein a telephone number of a respective online service is preliminarily stored in a respective empty channel, and the telephone number is dialed through the modem when a user specifies the empty channel corresponding to the respective online service, thereby connecting the online service with the response server.

3. A data broadcast receiving apparatus of claim 2, wherein dialing is effected when the respective empty channel corresponding to the respective online service is accessed for a specific duration.
