1. A decoder for decoding a block on a bitstream, the decoder being operable to extract triangular prediction configuration information from the bitstream, on the basis of which the decoder is operable to generate a prediction comprising two parts corresponding to a triangular partition of the block, at least one of the parts being predicted using information obtained by intra-prediction, and wherein the decoder is operable to extract, from the bitstream, triangular prediction information comprising an index to one of a plurality of sets of prediction configuration attributes, each set of prediction configuration attributes being capable of being used to configure the decoder to generate a prediction in accordance with a particular triangular partition-based prediction mode, wherein each set of prediction configuration attributes comprises at least one of:
an inter-prediction mode indicator on the basis of which the decoder is to form an inter-prediction for the samples in a triangular partition;
an intra-prediction mode indicator on the basis of which the decoder is to form an intra-prediction for the samples in the triangular partition.
