Abstract

A text broadcast receiver includes a data extraction circuit for extracting a data block in an encoded transmission-format text broadcast signal multiplexed to a vertical blanking period of a video signal, a data group construction circuit for constructing a data group by assembling a plurality of extracted data blocks, a data identifier for passing identifying the data group containing a television program table, a memory for storing the television program table contained in the data group passed through the data identifier, and display control circuit for reading the television program table from the memory and for displaying the television program table on a screen. The text broadcast receiver further includes a remote control selector for selecting at least one television program in the displayed television program table. The selected television program is recorded as a reserved television program for recording.

Claims

1. A text broadcast receiver comprising:

a data extraction means for extracting a data block in an encoded transmission-format text broadcast signal multiplexed with a vertical blanking period of a video signal;

a data group construction means for constructing a data group by assembling a plurality of extracted data blocks;

a data identifying means including a first means for passing said data group when said data group contains a television program table;

a memory means for storing said television program table contained in said data group passed through said first means of said data identifying means, said memory means including an area for storing channel information and an area for storing a starting time and an area for storing an ending time for each stored program in said television program table; and

a display control means for reading said television program table from said memory means and for displaying the television program table on a screen.

2. A text broadcast receiver as claimed in claim 1, further comprising a select means for selecting at least one television program in the displayed television program table, said selected television program being recorded as a reserved television program for recording.

3. A text broadcast receiver as claimed in claim 1, further comprising:

a second means of said data identifying means for passing said data group when said data group contains a program index data; and

a program index processing means for processing said data group obtained from said second means of said data identifying means for controlling the program numbers for text broadcast programs.

4. A text broadcast receiver as claimed in claim 1, further comprising:

a second means of said data identifying means for passing said data group when said data group contains a page data; and

a decoding means for decoding said data group obtained from said second means of said data identifying means into either one of visual data for display on a screen and audio data for producing sound from a loud speaker.

5. A text broadcast receiver comprising:

a data extraction means for extracting a data block in an encoded transmission-format text broadcast signal multiplexed with a vertical blanking period of a video signal;

a data group construction means for constructing a data group by assembling a plurality of extracted data blocks;

a data identifying means including a first means for passing said data group when said data group contains a television program table;

a memory means for storing said television program table contained in said data group passed through said first means of said data identifying, said memory means including an area for storing channel information and an area for storing a starting time and an area for storing an ending time for each stored program in said television program table;

a display control means for reading said television program table form said memory means and for displaying the television program table on a screen;

a select means for selecting at least one television program int eh displayed television program table, said selected television program being identified as a reserved television program for recording;

a second means of said data identifying means for passing said data group when said data group contains a program index data;

a program index processing means for processing said data group obtained from said second means of said data identifying means for controlling the program numbers for text broadcast programs;

a third means of said data identifying means for passing said data group when said data group contains a page data; and

a decoding means for decoding said data group obtained from said third means of said identifying means into either one of visual data for display on a screen and audio data for producing sound from a loudspeaker.
