Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0042] In order to realize the real-time rendering and presentation of the media content within the user's field of view and the real-time switching of the field of view, it is necessary to indicate the spatial attributes of the media content. Considering that human eyes have different sensitivities to different areas within the field of view, it is also necessary to indicate the quality information of the panoramic video. In this way, the indexing of media content can be performed normally when r...

Abstract

The invention provides a panoramic video rendering and presentation attribute indication method and system. The method comprises the following steps: inserting first indication information, second indication information and / or third indication information in description information associated with panoramic video rendering and presentation for a panoramic video; the first indication information indicates a media content attribute of the panoramic video, and comprises an identifier of a mapping format of the panoramic video, and an identifier indicating whether the panoramic video covers a 360-degree view angle, the second indication information is used for indicating the space information of the panoramic video; the third indication information is used for indicating the quality information of the panoramic video. According to the invention, rendering and presentation of the media content based on the visual angle can be realized, and the panoramic video matched with the visual angle can meet the high-quality consumption demand of a user on the panoramic video as much as possible under the condition that the network bandwidth is limited.

Description

[0001] This application is a divisional application of the invention patent application "a panoramic video rendering and presentation attribute indication method and system" with an application date of December 14, 2016 and an application number of CN201611155809.7. technical field [0002] The present invention relates to the technical field of digital media, in particular to a panoramic video rendering and presentation attribute indication method and system, which provides necessary indication information for panoramic video and is used for real-time rendering and presentation of panoramic video. Background technique [0003] With the rapid development of digital media technology, immersive media has gradually become one of the development directions of future media. While industry and academia are extensively investing in panoramic video production and coding research, the transmission of panoramic video is also facing some problems that need to be solved. [0004] For th...
