METHOD AND APPARATUS HAVING VIDEO ENCODING FUNCTION WITH SYNTAX ELEMENT SIGNALING OF ROTATION INFORMATION OF CONTENT-ORIENTED ROTATION APPLIED TO 360-DEGREE IMAGE CONTENT OR 360-DEGREE VIDEO CONTENT REPRESENTED IN PROJECTION FORMAT AND ASSOCIATED METHOD AND APPARATUS HAVING VIDEO DECODING FUNCTION

摘要

A video processing method includes: receiving a current input frame having a 360-degree image/video content represented in a 360-degree Virtual Reality (360 VR) projection format, applying content-oriented rotation to the 360-degree image/video content in the current input frame to generate a content-rotated frame having a rotated 360-degree image/video content represented in the 360 VR projection format, encoding the content-rotated frame to generate a bitstream, and signaling at least one syntax element via the bitstream, wherein the at least one syntax element is set to indicate rotation information of the content-oriented rotation.
