First Claim
1. A device for programming a video recorder using time and date information contained in a teletext page, which device comprises an input terminal for receiving the information contained in a teletext page, a date detector for detecting a date present in the information of the teletext page, and a time detector for detecting a time present in the information of the teletext page, wherein the improvement comprises:
- the time detector includes means for detecting time information from at least four consecutive characters in the information of the teletext page, in a form other than exactly four consecutive digits, for detecting time information in the form of exactly four consecutive digits in the information of the teletext page, and for accepting the four consecutive digits as a time unless the time detector has detected time information in a form other than exactly said four consecutive digits in the information of the teletext page.

Abstract
An improved programming of a video recorder comprising a first step enables time information as included in a teletext page by, for example, the BBC to be identified as such. A second step enables the date detected from the teletext page to be incremented by one day in the case of date allocation for programs starting after midnight.

13. A device for programming a video recorder, comprising:
-
a) an input terminal for receiving the information contained in a teletext page; b) date detection means for detecting a date present in the information of the teletext page; c) time detection means for detecting a time present in the information of the teletext page; d) means for assigning a date detected by the date detection means to a time detected by the time detection means; and e) means for assigning an incremented date, equal to the detected date incremented by one day, to the detected time if a time subsequently detected from the teletext page represents an instant prier to the previously detected time. - View Dependent Claims (14)
