Claim 6:
7. A non-transitory computer readable medium having stored thereon a compressed image data, the compressed image data comprising at least one of:
a reference sample line index indicating one of a plurality of pre-defined reference sample lines or an MPM (Most Probable Mode) flag indicating whether an intra prediction mode of the current block is derived from MPM candidates,
wherein, in response to the MPM flag being equal to a first value, the intra prediction mode of the current block is derived from the MPM candidates or a default mode,
wherein, in response to the MPM flag being equal to a second value, the intra prediction mode of the current block is not derived from the MPM candidates and the default mode,
wherein, in response to the MPM flag being equal to the first value, the compressed video data further comprises a default mode flag indicating whether the intra prediction mode of the current block is set equal to the default mode,
wherein the default mode is representative of a Planar mode, and
wherein, in response to the reference sample line index being greater than a pre-defined value, the MPM flag is not comprised in the compressed video data and a value of the MPM flag is inferred to the first value.
