1. A method for analyzing a multimedia content, constituted by a temporal succession of elementary entities, aimed at checking whether or not the multimedia content includes a portion of at least one reference content referenced in a base of reference contents, wherein the method comprises the following steps for at least one elementary entity, of the multimedia content that is to be analyzed, and that is selected according to a predetermined selection rule, called a current elementary entity: allocating, with a device, a likelihood probability to each elementary entity of a set of current candidate elementary entities, said likelihood probability taking into account a similarity between said elementary candidate entity and said current elementary entity of said multimedia content; allocating a transition probability between said current candidate elementary entity or entities and at least one previous candidate elementary entity; allocating an identification probability of at least once scenario formed by a temporal succession of candidate elementary entities, taking into account: the likelihood probabilities allocated to the candidate elementary entities of said scenario; and the transition probabilities allocated to the candidate elementary entities of said scenario; and deciding to perform at least one of recognizing one of said reference contents or continuing analysis by a following elementary entity of said multimedia content, as a function of said identification probability.
