Patent ID: 7565679

Claim:
A method of displaying slow motion sequences included in audiovisual transmissions received from a broadcasting network, wherein the method comprises prior steps of detecting the slow motion sequences of said transmissions and recording at least the detected slow motion sequences in a memory of a receiver; and a step of displaying the slow motion sequences displayed consecutively, the displaying of each recorded sequence being accelerated, the step of detecting slow motion sequences within transmissions composed of frames comprising: a) a step of motion detection operating on two consecutive frames extracted from the audiovisual transmissions, said step generating a string of values of motion or of absence of motion of binary indicators respectively indicating the presence or the absence of motion between the two relevant frames, b) steps of determining a frame repetition pattern composed of a motion value and of a consecutive string of at least one absence of motion value, said repetition pattern having a length, c) at least one step of constructing a reference pattern from a first frame repetition pattern, d) steps of detecting patterns composed of a string of values of motion and of absence of motion of a length equal to that of the reference pattern, e) steps of comparing between the reference pattern and patterns previously determined in step d), f) a step of reckoning up in a so-called confidence counter the number of identities between the reference pattern and the patterns determined during steps d), g) a step of validating the presence of a slow motion sequence when the value of the confidence counter is greater than a determined value.
