A method of generating a sequence of packets representing a stream of one or more media frames at an encoding system, the method comprising: in dependence on a measure of data loss over a network, determining a level of error correction data required in respect of a stream of media frames in order to substantially satisfy a recovery parameter expressing a target proportion of packets recoverable using error correction data; in dependence on the determined level of error correction data, identifying a target encoding bitrate so as to not exceed a target transmission bitrate over the network; encoding the stream of media frames so as to generate encoded data at the target encoding bitrate; and processing the encoded data and error correction data formed in respect of the stream of media frames so as to generate a sequence of packets at a rate commensurate with the target transmission bitrate. |
