摘要： There is disclosed a method and a system for rendering a page encoded in a mark-up language source. Many particular embodiments relate to rendering documents encoded in Hypertext mark-up language ("HTML"). The method comprises a translating step in which the mark-up language source is translated into data in an intermediate format and a display step in which a display rendering the page is generated. The intermediate language data preferably includes all information needed to generate the display in the display step, such that the mark-up language source need not be referred to in the display step. The intermediate language data is preferably binary format data.

摘要： A method for broadcasting over an IP multicast network an offer of multimedia services received in form of a bundle of transport streams, comprises attributing for each offer (offer 1, offer 2) a determined service provider offer localisation (LN0,1, LNO,2) of the IP multicast network, and creating a file of offer information (701) describing for each offer a relation to its attributed service provider offer localisation. For each offer transport stream information is extracted from its bundle, the transport stream information comprising a transport stream identification (TS1,1 TS1,4, TS2,1 TS2,3) for each transport stream. For each transport stream identification is attributed a determined stream localisation (LN1,1 LN1,4, LN2,1 LN2,3) within the IP multicast network. For each offer is created a file of stream information (702, 703) describing for each transport stream a relation to its attributed stream localisation.

摘要： The invention concerns a method for revoking access rights to an audio-visual programme received by a decoder (11) comprising the following steps: transmitting first messages (ECM) containing encrypted control words, each control word (CW) being used to descramble for a given time period the audio-visual signal received, second messages (EMM) comprising each data allocating user rights; decrypting in the decoder, or a portable object associated therewith, the first messages to produce control words (CW) for descrambling said audio-visual signal received by the decoder (11), transmitting third hybrid messages resulting each from the combination of at least one encrypted control word (CW), a decoder address and a right revoking information.

摘要： A digital satellite television system has a plurality of set-top-boxes associated with a plurality of end users' television receivers, a modem and a decoder housed in each STB, a Subscriber Authorization System (SAS) incorporating or having associated therewith a plurality of communication servers, means included in the SAS for generating Electronic Managements Messages (EMM), a back channel interconnecting each of the STBs individually with the SAS, means included in the SAS and each STB so that the necessary information required to inject a relevant EMM into the system is supplied directly to the relevant communication server included in or associated with the SAS to authorise the release of the said EMM and/or means to connect the modem to the back channel and means whereby an EMM is transmissible to the decoder directly from a relevant communication server included in or associated with the SAS. Further important features are also disclosed.

摘要： A method for pairing a first element and a second element, wherein the first element and the second element form a first decoding system among a plurality of receiving decoding systems in a broadcasting network. Each receiving decoding system is adapted to descramble scrambled audiovisual information received over the broadcasting network. A first key unique in the broadcasting network is selected. A second key is determined according to the first key, such that a combination of the first key and the second key enables to decrypt broadcasted encrypted control data that is received to be decrypted by each receiving decoding system, the encryp ted control data being identical for each receiving decoding system. The first key and the second key are assigned respectively to the first element and the second element.
