EP2681912B1 - Lossless data coding for bidirectional communication in a collaborative session of multimedia content exchange
Codage de données sans perte pour communication bidirectionnelle dans une session collaborative d'échange de contenu multimédia
Résumé
This method of coding data comprises, the exchange (E10) between the sender and the receiver, in the course of the session, of attributes of collaboration messages (CIU) able to be used in said session and of indices associated with these attributes, the attributes and their indices being used by these items of equipment to update a shared dictionary (ETU) of indexed attributes. On coding, the attributes of the collaboration messages are substituted (E50) by their indices; on decoding, the inverse operation is carried out. The shared dictionaries are destroyed (E100) at the end of the session.
