Improvement for intra-inter prediction mode

An apparatus for video encoding, the apparatus comprising:

• at least one memory configured to store computer program code;
• at least one hardware processor configured to access the computer program code and operate as instructed by the computer program code, the computer program code including:
• receiving code configured to cause the at least one processor to receive video data;
• and
• encoding code configured to cause the at least one processor to encode the video data to signal decoding based on:
• selecting based on whether an intra mode uses different initial weighting factors of position dependent intra prediction combination (PDPC) than PDPC, a set of weightings in an intra-inter mode, and
• applying PDPC to modify at least one of an inter prediction sample and another sample.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

• receiving video data;
• and
• encoding the video data to signal decoding of the video data based on:
• selecting, based on whether an intra mode uses different initial weighting factors of position dependent intra prediction combination (PDPC) than PDPC, a set of weightings in an intra-inter mode, and
• applying PDPC to modify at least one of an inter prediction sample and another sample.
