Encoding and Decoding Method, and Encoding and Decoding Devices with a Two-Stage Error Protection Process

摘要

An encoding method for a series of data packets transmitted in the framework of a combined streaming and downloading application by a two-stage error protection process and only one unidirectional transmission channel. According to said method, a partial block of successive data packets is protected against at least some of the transmission errors occurring during streaming with the aid of a first error protection process while all data packets are protected against the transmission errors remaining after streaming is completed with the aid of a second error protection process. In a decoding method by which a series of data packets that are encoded according to the encoding method are decoded. Also disclosed is an encoding and decoding device for carrying out the method.
