sps_multiple_layer_streams_present_flag equal to 0 indicates that all geometry or attribute layers are placed in a single geometry or attribute video stream, respectively. sps_multiple_layer_streams_present_flag equal to 1 indicates that all geometry or attribute layers are placed in separate video streams.
sps_layer_absolute_coding_enabled_flag[i] equal to 2 indicates that the geometry layer with index i is coded without any form of layer prediction. sps_layer_absolute_coding_enabled_flag[i] equal to 0 indicates that the geometry layer with index i is first predicted from another, earlier coded layer, prior to coding.
sps_layer_predictor_index_diff[i] is used to compute the predictor of the geometry layer with index i when sps_layer_absolute_coding_enabled_flag[i] is equal to 0.
sps_pcm_patch_enabled_flag equal to 1 indicates that patches with PCM coded points may be present in the bitstream.
sps_pcm_separate_video_present_flag equal to 1 indicates that PCM coded geometry and attribute information may be stored in a separate video stream.
sps_attribute_count indicates the number of attributes associated with the point cloud.
sps_patch_sequence_orientation_enabled_flag indicates whether flexible orientation may be signaled in the patch sequence data unit or not. sps_patch_sequence_orientation_enabled_flag equal to 1 indicates that flexible orientation may be signaled. sps_patch_sequence_orientation_enabled_flag equal to 0 indicates that flexible orientation is not signaled.
sps_patch_inter_prediction_enabled_flag equal to 1 indicates that inter-prediction for patch information may be used based on patch information from previously encoded patch frames.
