Abstract
Abstract A VTR having video recording reserving function and capable of receiving teletext broadcasting selects a program list data out of the teletext data and stores the same in a picture data memory (10). The program list data includes character data related to the date, time and the like of programs to be broadcasted. A group classifying circuit (6b) determines types of characters constituting these character data one by one and collects continuous characters of the same type as one group, so as to classify the character data into various character groups. A decoding circuit (6c, 6d) decodes time or date information based on the character group indicative of numerals or the character group indicative of month. The information decoded in this manner is taken in a reservation data memory (19), and the reserved video recording is carried out based on the data.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
A video tape recorder capable of receiving teletext data transmitted multiplexed in a vertical blanking period of a television video signal and capable of taking at least character data indicative of time information related to a program to be broadcasted out of received said teletext data to utilize the same in reserving video recording of said program to be broadcasted, characterized by: character group classifying means (6b) for classifying said character data into at least one character group by determining types of characters constituting said character data one by one successively and by grouping continuous characters of the same type as one group; and time decoding means (6c) for decoding said time information based on an arrangement of a character group indicative of numerals out of said at least one character group classified by said character group classifying means.
Claim 2
Dependent Claim
139 words
A video tape recorder capable of receiving teletext data transmitted multiplexed in a vertical blanking period of a television video signal and capable of taking at least character data indicative of time information related to a program to be broadcasted out of received said teletext data to utilize the same in reserving video recording of said program to be broadcasted, characterized by: character group classifying means (6b) for classifying said character data into at least one character group by determining types of characters constituting said character data one by one successively and by grouping continuous characters of the same type as one group; and time decoding means (6c) for decoding said time information based on an arrangement of a character group indicative of numerals out of said at least one character group classified by said character group classifying means.
