Digital data stream e.g. audio stream, restoring method for e.g. wireless fidelity network, involves transporting data stream i.e. degraded stream, corresponding to degraded version of distinct stream of nominal stream, and restoring stream

摘要

#CMT# #/CMT# The method involves requesting for a transport of a data stream i.e. nominal stream, having a quality level, by a client terminal (10). The stream transmitted by operator equipment (20) of a communication network is restored. A digital data stream i.e. degraded stream, is transported by the terminal, where the degraded stream corresponds to a degraded version of a distinct stream of the nominal stream and having a quality level lower than that of the quality of the nominal stream. The degraded stream transmitted by the equipment of the network is restored. #CMT# : #/CMT# Independent claims are also included for the following: (1) a digital stream restoration terminal comprising a request unit for the transportation of stream (2) a downloadable computer program product comprising a program code instructions for executing a method for restoring the digital stream. #CMT#USE : #/CMT# Used for restoring digital stream such as audio stream, and audio visual stream by client terminal within a communication network (claimed) such as Digital line subscriber and Wireless fidelity network that identifies a standard leading to the construction of wireless local area network and IEEE 802.11. #CMT#ADVANTAGE : #/CMT# The method permits to restore the degraded stream transmitted by the equipment of the network, thus permitting to rapidly change the program according to the perception of user in a framework of transmission of audio visual stream on a limited bandwidth line. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of initialization of diffusion of digital channels. 10 : Client terminal 12 : Nominal channel 14 : Internet group management protocol message 20 : Operator equipment 30 : Network connection.
