摘要： Apparatus for encrypting a stream of audiovisual data generated by an encoder (11); comprises an encrypter (113) module that analyses the data stream to determine if said stream includes at least one slice relative to a layer of video codification; for encrypting at least a set of bit nearby or adjacent to a slice header; and inserts the generated encrypted set of bit into the data stream that will be transported by a digital telecommunications network (12) to a customer's local equipment.
