Abstract

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 Analysis

Total Claims: 5
Claim 1
Independent Claim 107 words
A text broadcast receiver comprising: data extraction means for extracting a data block in an encoded transmission-format text broadcast signal multiplexed to a vertical blanking period of a video signal; data group construction means for constructing a data group by assembling a plurality of extracted data blocks; first gate means for passing said data group when said data group contains a television program table; memory means for storing said television program table contained in said data group passed through said first gate means; and display control means for reading said television program table from said memory means and for displaying the television program table on a screen.
Claim 2
Dependent Claim 39 words
A text broadcast receiver as claimed in Claim 1, further comprising 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.
Claim 3
Dependent Claim 53 words
A text broadcast receiver as claimed in Claim 1, further comprising: second gate means for passing said data group when said data group contains a program index data; and program index processing means for processing said data group obtained from said second gate means for controlling the program numbers for text broadcast programs.
Claim 4
Dependent Claim 68 words
A text broadcast receiver as claimed in Claim 1, further comprising: third gate means for passing said data group when said data group contains a page data; and decoding means for decoding said data group obtained from said third gate means to either one of visual data for being able to display through a screen and audio data for being able to produce sound from a loud speaker.
Claim 5
Dependent Claim 232 words
A text broadcast receiver comprising: data extraction means for extracting a data block in an encoded transmission-format text broadcast signal multiplexed to a vertical blanking period of a video signal; data group construction means for constructing a data group by assembling a plurality of extracted data blocks; first gate means for passing said data group when said data group contains a television program table; memory means for storing said television program table contained in said data group passed through said first gate means; display control means for reading said television program table from said memory means and for displaying the television program table on a screen; select means for selecting at least one television program in the displayed television program table, said selected television program being identified as a reserved television program for recording; second gate means for passing said data group when said data group contains a program index data; program index processing means for processing said data group obtained from said second gate means for controlling the program numbers for text broadcast programs; third gate means for passing said data group when said data group contains a page data; and decoding means for decoding said data group obtained from said third gate means to either one of visual data for being able to display through a screen and audio data for being able to produce sound from a loud speaker.
