Abstract
A media content-based adaptive method, device and system for Forward Error Correction (FEC) coding and decoding of a systematic code, and a medium are provided. The method includes: dividing, according to the importance of media content, source data into N types of source data packets according to priorities; generating N types of intermediate codes according to the N types of source data packets and the priorities thereof; setting, according to the N types of intermediate codes, recovery data of N types of source data according to a channel condition, and generating coded symbols of N types of systematic codes; receiving the coded symbols, and arranging and sorting the coded symbols according to decoding requirements; and decoding, according to the number of received coded symbols, intermediate codewords according to different situations, and recovering the corresponding source data packets according to the intermediate codewords.
