Abstract: This demodulator for signals transmitted by bursts of data packets and the corresponding method comprise receiving from a separate processor identifiers of bursts to be processed, filtering the signals to retrieve the bursts whose identifiers were received, processing said retrieved bursts, receiving from said separate processor timing information associated with the identifiers of bursts to be processed; and power management to drive at least some components of said demodulator between an idle state and an active state depending upon said timing information.

Abstract: This method for receiving a data stream transmitted over several radiofrequency channels each with a different frequency, comprises scanning the bandwidth to identify available radiofrequency channels, determining a quality indicator for each available radiofrequency channel and selecting a channel for receiving the data stream depending upon said quality indicators. The method further comprises determining a refreshing period for the quality indicator of each available channel and weighting every determined refreshing period depending on the value of the quality indicator of the currently received channel.

Abstract: This method is for processing data frames (Fi) received over a communication channel, each data frame (Fi) comprising a data section (Si) for forming part of a data table and location information (Mi) associated with the data section and designating a location of said section within the data table. The data table and a metadata table (MT) are built and stored as the data frames are received, to be made available to a host processor (2). The method comprises the following steps for each received data frame: —buffering (10, 12) the data section of the received frame and the associated location information; —determining (14) an address for the data section in a table memory (8) based on the location information; —writing the data section at the determined address into the table memory; and—writing an entry of a metadata table, wherein said entry comprises the location information.

Abstract: This invention concerns a method for receiving a data stream comprising data sections spread on data packets. An error correction code is associated with and transmitted with every data section. The method comprises the steps of receiving the packets of the data stream by an interface module and transmitting the data stream, packet-by-packet, from the interface module to a processing module. The method also comprises that upon reception of data by the interface module, incrementally computing an error correction code for the current data section and when the entire section has been received, verifying the incrementally computed error correction code to deliver a section validity indicator.
