  • Publication number: 20140115100
    Abstract: A video packets scheduling method for multimedia streaming toward a receiver (7) provided with a video decoder (72), via a transmission chain including an access point (11) and a proxy (3), said proxy (3) provided with post-encoder buffers (31) and with a controller (32), said access point (11) provided with a buffer (4) of lower layer, said method comprising a resolution step of an optimisation problem controlling the state of the buffer (4) in the access point (11) and the state of the post-encoder buffers (31) in the proxy (3).

  • Patent number: 8489968
    Abstract: A method for recovering transmission errors, comprising: receiving a data packet comprising an error detection code associated to data contained in the packet, wherein the data associated to the error detection code comprises primary data and secondary data, checking the error detection code of the received packet to detect an erroneous state of the associated data, when the erroneous state is detected, determining a finite set of candidate values for the primary data and, for each values of the set: determining a marginal likelihood of the candidate value as a function of the error detection code of the received packet, determining a first correlation between the primary data of the received packet and the candidate value, and selecting a corrected value for the primary data among the set of candidate values as a function of said marginal likelihoods and said first correlations.

  • Publication number: 20110087952
    Abstract: A method for recovering transmission errors, comprising: receiving a data packet (50) comprising an error detection code (51) associated to data contained in the packet, wherein the data associated to the error detection code comprises primary data (52) and secondary data (53), checking the error detection code of the received packet to detect an erroneous state of the associated data, when the erroneous state is detected, (86) determining a finite set of candidate values for the primary data and, for each candidate values of the set: determining a marginal likelihood of the candidate value as a function of the error detection code of the received packet, determining a first correlation between the primary data of the received packet and the candidate value, and selecting a corrected value for the primary data among the set of candidate values as a function of said marginal likelihoods and said first correlations.

  • Publication number: 20110083032
    Abstract: A permeable protocol layer decoder (10) for decoding a protocol data unit comprises an error detection code checking means (2) for checking an error detection code of the protocol data unit to detect an erroneous state of the control data, and a control data correction means (6) operable to determine a finite set of candidate values for the control data, to determine error detection code values associated to the candidate values of the set, to determine first correlations between the control data of the received protocol data unit and the respective candidate values, to determine second correlations between the error detection code of the received protocol data unit and error detection code values associated to the respective candidate values, and to select a corrected value of the control data among the set of candidate values as a function of said first and second correlations.
