Title:
ポイントクラウド符号化における改善された属性サポート
Document Type and Number:
Japanese Patent JP7130853
Kind Code:
B2
Abstract:
A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a plurality of coded sequences of point cloud coding (PCC) frames. The plurality of coded sequences of PCC frames represent a plurality of PCC attributes including geometry, texture, and one or more of reflectance, transparency, and normal. Each coded PCC frame is represented by one or more PCC network abstraction layer (NAL) units.The mechanism also includes parsing the bitstream to obtain, for each PCC attribute, an indication of one of a plurality of video codecs used to code the corresponding PCC attribute. The mechanism also includes decoding the bitstream based on the indicated video codecs for the PCC attributes.
