METHOD AND INSTALLATION FOR UPLOADING A USER'S DECODER PLATFORM

摘要

The invention concerns a method for uploading the software application particular to an operator in an unmarked platform of a digital television decoder, which consists in storing once and for all, in a protected and non-rewritable memory zone of the platform, an safety initialising and starting loader; periodically broadcasting, in the digital television signal coming from an operator arranged to be accessible, a message containing the application programme enabling the platform to decode the operator television signal data flow and to process the services. Said message comprises an electronic signature. At reception level, the messages containing the programme are selected, decoded and written in programme rewritable memory, optionally controlled by the user.
