Patent ID: 8238368

Claim:
A method of managing erratic interruptions in a transmission system where messages to be transmitted are composed of data packets and are represented by a polynomial of degree t−1, one or more senders and one or more receivers sharing information enabling referencing of the data packets, comprising the method of: in the course of the transmission of a message represented by a polynomial P, generating at least t′ points Ai and the evaluations P(Ai) of the polynomial P, with t′ greater than or equal to t, transmitting the evaluations P(Ai) of the t′ points to the receiver or receivers, with information allowing the receivers to detect transmission errors, each receiver: verifying reception of t valid evaluations, the valid evaluations being free of transmission errors, determining the points Ai based on the information referencing the data packets and the t valid evaluations P(Ai) of the polynomial, and on the basis of the P(Ai) and of the Ai, determining the polynomial P used based on the P(Ai) and Ai and deducing the message on the basis of said polynomial P; wherein a signaling C0 associated with a message C is transmitted, the signaling being composed of T0*N0 bits and seen as a polynomial of degree (T0−1) and on reception: T0 pages not containing any errors are collected, and each page using a different point from the other pages, on the basis of these pages the signaling CO is reconstructed using a polynomial interpolation, wherein N0 is a number of bits; the length of the message C and the way in which the message C has been sliced into F frames are deduced on the basis of C0, each frame sliced into q words, each of the words being represented by a polynomial of degree (T−1), T error-free evaluations of the polynomial are collected for each polynomial corresponding to a word, and by using distinct points, the message C is reconstructed using the polynomial interpolation.
