Zusammenfassung:Opportunistic data are transmitted only when the datum quality level in the transmission channel is reached by all video coders (A1-An) and the quality level may vary from coder to coder. A throughput allocation unit (50) distributes the throughputs among the coders and a multiplexer sends empty packets so as to fill up the transmission channel (54). The empty packets can be replaced by the opportunistic packets by a data inserter (53). Independent claims are included for a video data quality monitoring device and for a video data coding system.
