Document Type and Number:
WIPO Patent Application WO/2019/009319
Kind Code:
A1
Abstract:
Informations associated omnidirectional video in MPD (Media Presentation Description) are disclosed. They contain "region-wise quality ranking information" in a set of values using a comma separated list enclosed by delimiters. (See paragraphs [0180],[0216]-[0218],[0292],[0293] and Figure 10.) They also contain "view indicator", "yaw of a center point", "pitch of a center point", "roll angle", "horizontal range" and "vertical range". (See paragraphs [0218] and [0287].) They also contain "projection type" or "region-wise packing information" as a list of unsigned bytes. (See paragraphs [0356],[0359] and Figures 13A, 13B, 14A, 15A.) They also contain "top level element" and "common set of attributes". (See paragraphs [0009],[0010].)
