Abstract: A method for providing a context datum associated with a source and/or destination device based on an address datum associated with the device, including addressing, based on the address datum, a unit for providing an index, the unit containing, for each address datum, an indicator indicating whether the device is active; and addressing, based on the index provided by the unit, a context memory for providing the context datum associated with the device.

Abstract: A method is provided for controlling the rates of concurrent digital transmissions using at least a first queue having a plurality of locations. For each transmission, an index corresponding to a data cell of the transmission is written at one of the locations in the first queue, and the locations of the first queue are successively surveyed at a rate corresponding to a cell transmission rate. If the surveyed location in the first queue contains an index, the corresponding data cell is transmitted, the location is freed, and the index is rewritten at the location in the first queue that is distant from the surveyed location by a value determined by the rate of the corresponding transmission. In one preferred method, indexes corresponding to high priority transmissions are written into the first queue and indexes corresponding to lower priority transmissions are written into a second queue. Also provided is a method for controlling the rates of concurrent digital transmissions using at least first and second queues.

Abstract: A device for associating indexes to addresses chosen from among a greater number of values than the number of available indexes, including a memory containing indexes and respective check words corresponding to predetermined bits of the addresses associated with the indexes; a packing circuit receiving a current address and suppressing in this address bits determined by a pattern such that the suppressed bits correspond to bits of the check words, the packed address provided by the packing circuit being used to select in the read mode a memory location; and a comparator indicating that the current address corresponds to the selected memory location if the bits of the check word of the selected location are equal to the corresponding bits of the current address.

Abstract: A method and a system for coding digital data represented by source symbols (Si) with an error-correction code. The error-correction code generates parity symbols (Pj) based on, for each parity symbol, several source symbols and at least one parity symbol of preceding rank. At least a part of the source symbols is submitted to at least a first ciphering. The obtained ciphered symbols and the rest of the unciphered source symbols are submitted to the error-correction code.

Abstract: A method and a system for coding digital data represented by source symbols (Si) with an error-correction code. The error-correction code generates parity symbols (Pj) based on, for each parity symbol, several source symbols and at least one parity symbol of preceding rank. At least a part of the source symbols is submitted to at least a first ciphering. The obtained ciphered symbols and the rest of the unciphered source symbols are submitted to the error-correction code. Accordingly, the present disclosure improves the security of the transmitted data. The present disclosure is also compatible with the management of different groups of users. The present disclosure is well adapted to large-scale broadcasting systems and provides a solution compatible with any ciphering algorithm. In addition, the present disclosure is particularly well adapted for use with LDPC-type error-correction codes.
