11. An apparatus comprising:
a receiver configured to receive an encoded video frame; and
a video decoder coupled to the receiver, the video decoder configured to decode the encoded video frame, to produce a decoded video frame, the video decoder comprising:
one or more processors; and
a non-transitory computer readable storage medium storing a program for execution by the one or more processors, the programming including instructions to:
determine an intra-prediction angle based on prediction information of the encoded video frame;
determine a plurality of reference samples for a prediction unit (PU) based on the intra-prediction angle;
determine a predicted sample based on linear interpolation of at least two of the plurality of reference samples; and
decode the PU based on the predicted sample.
