摘要： The invention includes a mostly conventional digital television system (2000) to transmit compressed digital signals. A multiplexer (2004) receives a plurality of further input signals, assembles one or more transport streams and transmits compressed digital signals to a transmitter (2008) of the broadcast centre via linkage (2010). The transmitter (2008) transmits electromagnetic signals via uplink (2012) towards a satellite transponder (2014), where they are electronically processed and broadcast via notional downlink (2016) to earth receiver (2018). The signals received by receiver (2018) are transmitted to an integrated receiver/decoder (2020) connected to the end user's television set (2022). The receiver/decoder (2020) decodes the compressed MPEG-2 signal into a television signal for the television set (2022). A conditional access system (3000) is connected to the multiplexer (2004) and the receiver/decoder (2020), and is located partly in the broadcast centre and partly in the decoder. It enables the end user to access digital television broadcasts from one or more broadcast suppliers. A smartcard, capable of decrypting messages relating to one or several television programmes sold by the broadcast supplier, can be inserted into the receiver/decoder (2020). Using the decoder (2020) and smartcard, the end user may purchase commercial offers in either a subscription mode or a pay-per-view mode. A number of features of particular interest are disclosed, involving the randomization of EMMs, mixing parameter length and identifier on EMMs and the like to save space, dynamic allocation of bandwidth for specific EMMs, and the STM being separate from the SMS.

摘要： A receiver/decoder (for example for digital television) normally receives and/or decodes transmitted data in a normal transmitted signal. In order to test an application running on the receiver/decoder, a special test signal could be generated, or a normal signal could be modified before supply to the receiver/decoder. However, this is costly and complex. To overcome these problems, the receiver/decoder simulates the reception of such transmitted data to produce simulated data; and the application to be tested processes such simulated data in addition to, or instead of, such transmitted data.
Simulation may involve generating the simulated data in the receiver/decoder, or controlling the generation of the simulated data by a workstation and receiving the simulated data from the workstation. Data generation may employ a model of the transmitted signal, the model having various parameters which can be varied.
Data representative of the simulation may be stored in the receiver/decoder and/or transferred from the workstation to the receiver/decoder, for example in parts on a when-required basis.

摘要： The protocol detection mode used in the portable object comprises the following steps: a) an initial signal is received from the interface device after transmission of a response (E2) when (E1) the portable object is connected; the initial signal is sampled in the portable object according to at least one of the first and second speeds associated with the respective first and second protocols; c) at least one resulting sample of a sampling signal is compared to at least one key protocol condition proper to one of the first and second protocols (E4); d) the data exchanged according to one of the first and second communication protocols is treated in the portable object according to the result of said comparison. The portable object can be a chip card or a chip key.

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： The invention concerns a method for controlling access, in digital pay television, to data contained in the signal received by a subscriber receiving station (21) comprising steps which consist in transmitting first right allocation control messages (ECM) enabling proposal to subscribers of an on-demand operation mode and second right allocation management messages (EMM) to a user device (26), generating in the user device an access authorization signal (CW), wherein first right allocation control messages are transmitted having a parameterable profile content enabling at least one service or one programme to be authorized during a time slot based on the profile of a specific subscriber, so as to ensure an interactivity between the content of said first messages and the content of the user's device in terms of subscription for the subscriber.
