A system for encoding a sequence of frames (171) of a data signal. The system comprises: a first encoding system (120) comprising at least: a first encoder (130) configured to encode the sequence of frames (171) according to a first encoding algorithm; and a first rate control unit (135) configured to control a first bit rate at which the first encoder (130) encodes said sequence of frames (171); a second encoding system (100) comprising at least: a second encoder (116) configured to encode a second sequence of frames (175) associated with the sequence of frames (171) according to a second encoding algorithm; and a second rate control unit (135) configured to control a second bit rate at which the second encoder (130) encodes said second sequence of frames (175) associated with the sequence of frames (171).
