Abstract:
The errors that may occur in numerical transmitted data on a channel (240, 260) affected by burst errors, are corrected via the operations of: - ordering the numerical data in blocks each comprising a definite number (k) of data packets; - generating for each block a respective set of error-correction packets comprising a respective number (n-k) of correction packets, said respective number identifying a level of redundancy for correcting the errors; and - modifying dynamically the level of redundancy according to the characteristics of the bursts and of the correct-reception intervals between two bursts. Preferential application is on local networks, such as W-LANs for use in the domestic environments.
Abstract:
A system for controlling operation of a network such as a WLAN (200, 300) where at least one information stream is delivered to at least one user (250, 260; 350, 360) via at least one link exposed to variable operating conditions. The system includes:
a controller module (410) configured for monitoring the operating conditions (400, 410) of said link, and at least one transcoder (210, 310) configured for selectively transcoding (210, 310) the information stream by selectively varying one or more transcoding parameters as a function of the operating conditions monitored.
