#CMT# #/CMT# The system uses a broadcast to update the remote signal decoders, to minimise inconvenience to users. #CMT# : #/CMT# The method for updating data held within a video signal decoder for a television receiver includes transmission of the necessary updating data by a communication centre to terminals through a broadcasting network. This may be a satellite broadcast, a radio signal broadcast or by means of a coaxial or optical fibre cable offering one-way communications. The terminals inform the centre concerning their updating through a two-way network. The broadcast centre renews its updating campaign, or stops the present campaign on the basis of the number of updated terminals. Once the campaign has been stopped, the terminals can be updated using the two-way link. #CMT#USE : #/CMT# Updating decoding information used in video signal decoders and receivers. #CMT#ADVANTAGE : #/CMT# Enables most receivers to be updated with minimum inconvenience to users. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows the system for broadcast update of decoding information.
