Abstract: A method for the remote sharing of a computer office generated by an application executed in a server in response to commands issued by client terminals accessing this server via a telecommunication network, the commands of a client terminal being entered by means of an entry area termed the focus. The client terminals transmit, to the server, commands dedicated to office sharing, and entered by means of various focuses, in accordance with a graphics interface transmission protocol of the RUI type, standing for “Remote User Interface”, so that the server matches up, by means of the focuses, the commands received and the offices shared so as to transmit, in response to the commands from the terminals, a graphics interface representative of this office of the server by means of indications of the state of the pixels in this graphics interface in accordance with the RUI protocol.

Abstract: To modify a stream of encrypted multimedia data, a device connected to a control source and receiving said stream as an input performs the following steps: receiving a message coming from the control source, including information for identifying a separation of the incoming stream into at least one first substream and one second sub stream; deciphering the encrypted data of the first substream or substreams identified; modifying the encrypted data of the first substream or substreams identified, the modification being done using information received coming from the control source; encrypting the modified data of the first substream or substreams; and combining the first data substream or substreams, modified and encrypted, with the second substream, so as to obtain the stream of encrypted multimedia data sent as an output by the device.
