Embodiment Construction

[0033] In the following description and claims, some terms used will refer to a specific component. As is well known to those skilled in the art, manufacturers of electronic devices may use different names to refer to the same component. This document does not intend to distinguish between components that differ in name but do not differ in function. In the following descriptions and claims, words such as "including" and "comprising" are used as open statements, so they should be interpreted as "including, but not limited to...". Furthermore, the term "coupled" is used herein to denote a direct or indirect electrical connection. Accordingly, if one device is coupled to another device, that connection may be through a direct electrical connection or indirectly through other devices and links.

Abstract

A video processing method includes receiving a virtual reality (VR) content, obtaining a picture from the VR content, encoding the picture to generate a part of a coded bitstream, and encapsulating the part of the coded bitstream into ISO Base Media File Format (ISOBMFF) file (s). In one exemplary implementation, the ISOBMFF file (s) may include a transform property item that is set to enable at least one of a projection transformation, a packing transformation, a VR viewport selection, and a VR region of interest (ROI) selection in track derivation. In another exemplary implementation, the ISOBMFF file (s) may include a first parameter, a second parameter, and a third parameter associated with orientation of a viewport, with the first, second and third parameters indicating a yaw angle, apitch angle and a roll angle of a center of the viewport, respectively. Further, an associated video processing apparatus is provided.

Description

[0001] cross application [0002] This application claims U.S. Provisional Application No. 62 / 475,944, filed March 24, 2017, U.S. Provisional Application No. 62 / 476,939, filed March 27, 2017, and U.S. Provisional Application No. 62 / 476,939, filed March 29, 2017 Rights under No. 62 / 478,062. The entire contents of the above applications, including US Provisional Application No. 62 / 475,944, US Provisional Application No. 62 / 476,939, and US Provisional Application No. 62 / 478,062, are incorporated herein by reference. technical field [0003] The present invention relates to the processing of virtual reality (Virtual reality, VR) content, and more specifically, relates to a method for deriving VR projection, filling (image), ROI and viewport-related tracks in the ISO basic media file format, and supports Method and device for viewport scrolling signal. Background technique [0004] Virtual reality (VR) has recently gained significant attention primarily due to the near-term mar...
