Device for programming of recording by reference signals recognition
First Claim
1. A device for driving a recording apparatus for selective recording of an audio and/or video sequence from a set of received signal sequences, comprising:
- reducing means for reducing the set of received signal sequences to generate reduced data;
selecting means for selecting a reduced reference portion from the reduced data;
storing means for storing the selected reduced reference portion;
comparing means for comparing the stored reduced reference portion with the reduced data picked up from the set of received signal sequences and output by the reducing means; and
control means for controlling the recording apparatus to be activated to begin recording only when the comparing means detects a positive comparison between the stored reduced reference portion and the reduced data picked up from the set of received signal sequences.

Abstract
A driving device for driving a recording apparatus for selective recording of audio/video sequences, which is to actuate the recording apparatus at a precise instant of a beginning or of an ending of the audio/video sequence to be recorded. The driving device reduces picture datum from at least one reference picture belonging to the sequence to be recorded and a memory stores the reduced reference picture datum. A comparator compares the stored reduced reference datum with reduced picture data picked up from the set of picture sequences. A controller controls the recording apparatus to be activated to begin recording at the time the comparator detects a recognition of a picture similar to the stored reduced reference datum in the set of picture sequences.

10. A device for driving a recording apparatus for selective recording of a picture sequence from a set of electronic picture sequences, comprising:
-
means for reducing the set of electronic picture sequences to generate reduced picture data; selecting means for selecting at least one reduced reference picture from the reduced picture data; a memory for storing the selected reduced reference picture; a comparator for comparing the stored reduced reference picture with the reduced picture data picked up from the set of electronic picture sequences and output by the means for reducing; a controller for controlling the recording apparatus to be activated to begin recording only when the comparator detects a positive comparison between the stored reduced reference picture and the reduced picture data picked up from the set of electronic picture sequences. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A device for driving a recording apparatus for selective recording of at least one of an audio or video sequence from a set of received signal sequences, comprising:
-
a circuit for video recognition comprising; a reducing means for reducing video images from the set of received signal sequences to generate reduced video data; a selecting means for selecting a reference video portion from the reduced video data; a first memory for storing the selected reduced reference video portion; a first comparator for comparing the stored reduced reference video portion with the reduced video data picked up from the set of received signal sequences and output by the reducing means; a circuit for audio recognition comprising; sampling means for sampling audio signals from the set of received signal sequences and selecting a reference audio portion; a second memory for storing the selected reference audio portion; a second comparator for comparing the stored reference audio portion with the sampled audio signals picked up from the set of received signal sequences; a controller for controlling the recording apparatus to be activated to begin recording only when at least one of the first or second comparators detects a positive comparison.
