CA 2526016

To simulate film grain in a compressed video signal, a decoder (15, 28) receives a message containing information that contains a set of one or more parameters, each specifying certain attribute associated with the film grain. For example, one of the parameters will specify the model used to simulate the film grain, whereas other parameters each specify a particular factor associated with that model. Upon receipt of the message, the decoder selects the model, and simulates the film grain for addition to the video signal following decompression.

Afin de simuler le grain d'un film dans un signal vidéo comprimé, un décodeur (15, 28) reçoit un message contenant une information renfermant un ensemble d'un ou plusieurs paramètres, chacun spécifiant un attribut donné associé au grain du film. Par exemple, un des paramètres peut spécifier le modèle utilisé pour stimuler le grain du film, alors qu'un autre paramètre peut spécifier un facteur particulier associé à ce modèle. Après réception du message, le décodeur sélectionne le modèle et simule le grain de film en vue de son ajout au signal vidéo après décompression.
