摘要：The present disclosure relates to a method and device of decoding video data.The device and method use a mapping process to simplify the calculation procedure for
intra prediction, to improve coding efficiency. The decoding of encoded data comprises:obtaining an indication indicating whether the intra-prediction mode for a picture block isin a set of most probable modes, MPM, or not; if the indication indicates that the intraprediction mode for the picture block is not in the set of MPMs, generating a mappingrelationship between at least one intra prediction mode in the first set of intra predictionmodes and at least one intra prediction mode in the set of non-MPMs; decoding theencoded data to obtain an intra prediction mode codeword for the picture block; andobtaining the intra prediction mode for the picture block according to the mappingrelationship and the intra prediction mode codeword.
