Abstract

A television signal receiving apparatus is provided having a program schedule display function. The apparatus includes a tuner, a television signal processing circuit connected to the tuner, a digital signal processing circuit connected to the tuner for generating a program schedule display signal based on program schedule data obtained through the tuner, and a switch connected to the digital signal processing circuit for selectively generating a local program schedule display signal based on the Standard Time selected by the switch.

Claims

1. A television signal receiving apparatus having a program schedule display function, comprising:

tuner means;

television signal processing means connected to said tuner means;

digital signal processing means and associated switch means connected to said tuner means for generating a local program schedule display signal based on program schedule data obtained through said tuner means; and

said switch means being switchable between at least two time zones, and said digital signal processing means providing said local program schedule display signal with times based on a time zone selected with said switch means.

2. A television signal receiving apparatus as claimed in claim 1 wherein said switch means selects one of a plurality of different types of program schedule data for different Standard Times obtained from said tuner means.

4. A television signal receiving apparatus according to claim 1 wherein said television signal processing means includes de-scrambling means, and scrambled television signals obtained from said tuner means are supplied to said de-scrambling means.

5. A television signal receiving apparatus according to claim 4 wherein said digital signal processing means generates a Standard Times display signal based on the Standard Time selected by said switch means.

3. A television signal receiving apparatus having a program schedule display function, comprising:

tuner means;

television signal processing means connected to said tuner means;

digital signal processing means and associated switch means connected to said tuner means for generating a local program schedule display signal based on program schedule data obtained through said tuner means;

said switch means connected to said digital signal processing means selectively generating said local program schedule display signal based on a Standard Time selected by said switch means; and

said digital signal processing means including time schedule conversion means which changes time data included in the program schedule data to a selected one of a plurality of Standard Times.

6. A television signal program schedule display system, comprising:

a tuner means;

television signal processing means connected to said tuner means;

processing means and associated switch means connected to said tuner means for generating a local program schedule display signal based on program schedule data obtained from said tuner means; and

said switch means being switchable between at least two time zones and, depending upon the time zone selected, said digital signal processing means creating said local program schedule display signal based on said time zone selected.

7. A system according to claim 6 wherein said tuner means receives program schedule data based on a first of said at least two time zones, and said digital signal processing means includes conversion means for converting program schedule data containing data relating to the first time zone to data relating to the second time zone when said switch means is in said second time zone position.
