Description

The size of chroma component in text is same as 422, not 420. Change the PCM syntax 7.3.7.2 as follows.

pcm_sample( x0, y0, log2CbSize ) {
for( i = 0; i < 1 << ( log2CbSize << 1 ); i++ )

pcm_sample_luma[ i ]

for( i = 0; i < ( 1 << ( log2CbSize << 1 ) ) >> 2; i++ )

pcm_sample_chroma[ i ]

NumPCMBlock--
}

Current text is OK because Cb and Cr samples are parsed together in pcm_sample_chroma.
