Claim 10:
11. A prediction decoding apparatus, comprising:
a processor; and
a memory configured to store computer programs which, when executed by the processor, are operable with the processor to:
determine first multiple neighbouring reference samples of a coding block, wherein the first multiple neighbouring reference samples comprise reference samples in a reference row or a reference column neighbouring the coding block;
for the reference row, determine a value of K according to a length of the reference row, or for the reference column, determine the value of K according to a length of the reference column;
determine, from a starting position of the reference row or the reference column, positions corresponding to K reference samples, wherein K is a positive integer;
determine second multiple neighbouring reference samples according to the determined positions corresponding to the K reference samples, wherein the second multiple neighbouring reference samples comprise neighbouring reference samples among the first multiple neighbouring reference samples, wherein reference sample positions for the second multiple neighbouring reference samples are determined based on a sampling starting position indicative by the value of K; and
perform prediction decoding on the coding block according to the second multiple neighbouring reference samples,
wherein the processor configured to determine, from the starting position of the reference row or the reference column, the positions corresponding to the K reference samples is configured to:
for the reference row, determine, from a leftmost position of the reference row to the right, positions corresponding to K consecutive reference samples; or
for the reference column, determine, down from a topmost position of the reference column, positions corresponding to K consecutive reference samples.
