Claim 17:
18. A method for deblocking filter of palette mode, comprising:
receiving a video frame for processing;
generating two or more coding units for the video frame, wherein each coding unit of the two or more coding units have one or more coding blocks;
determining whether at least one of a first coding block of two neighboring coding blocks and a second coding block of the two neighboring coding blocks is coded in an intra prediction mode;
in response to the first coding block and the second coding block being not coded in the intra prediction mode, determining whether at least one of the first coding block and the second coding block is coded in an CIIP (combined inter and intra prediction) mode;
in response to the first coding block and the second coding block being not coded in the CIIP mode, determining whether at least one of the first coding block and the second coding block is coded in a palette mode; and
setting a boundary filter strength to 1 in response to the first coding block being coded in palette mode and the second coding block having a coding mode different from the palette mode.
