Embodiment Construction

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

[0034] figure 1It is a schematic diagram of a virtual reality (VR) system according to an embodiment of the present invention. V...

Abstract

A video processing method, comprising: receiving virtual reality (VR) content; obtaining an image from the VR content; encoding the image to generate a partially encoded bitstream; and encapsulating the partially encoded bitstream into an ISO base media file format (ISO Base Media File Format, ISOBMFF) file. In one illustrative example, the ISOBMFF file may include a transformation properties item set to enable at least one of projective transformation, packet transformation, VR viewport selection, and VR region of interest (ROI) selection in trajectory derivation . In another illustrative example, the ISOBMFF file may include a first parameter, a second parameter, and a third parameter associated with the orientation of the viewport. The first parameter, the second parameter and the third parameter respectively indicate the yaw angle, pitch angle and roll angle of the center of the viewport. Furthermore, associated video processing means are provided.

Description

[0001] cross application [0002] This application claims US Provisional Application No. 62 / 475,944, filed March 24, 2017, US Provisional Application No. 62 / 476,939, filed March 27, 2017, and US Provisional Application, filed March 29, 2017 No. 62 / 478,062 rights. 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 (VR) content, and more particularly, to a method for deriving VR projection, fill (image), ROI and viewport related trajectories in the ISO base media file format, and supports A method and apparatus for a viewport scroll signal. Background technique [0004] Virtual reality (VR) has recently gained significant attention mainly due to the recent market availability of consumer devices such as head mo...
