Problems solved by technology

In the prior art, the terminal needs to store the code stream of the panoramic space object in the local storage space, and then select the corresponding code stream to present according to the new space object. Occupies local storage space, and also causes a waste of network transmission bandwidth for video data transmission, poor applicability

Embodiment Construction

[0110] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0111] The current client-oriented system layer video streaming transmission solution can adopt the DASH standard framework, such as figure 1 , figure 1 It is a schematic diagram of a framework instance of DASH standard transmission adopted by system layer video streaming transmission. The data transmission process of the system layer video streaming media transmission scheme includes two processes: the server side (such as HTTP server, media content preparation...

Abstract

The embodiment of the invention discloses a processing method and device of video data based on HTTP (Hyper Text Transfer Protocol) dynamic adaptive steaming media. The method comprises the steps of:receiving a media presentation description; acquiring instruction information; if the instruction information is to view an author view code rate, obtaining a subsection of a first representation; andif not, obtaining the subsection of a second representation. The media presentation description includes information of at least two representations; the first representation of at least two representations is the author view code rate; the author view code rate includes multiple images; spatial information of spatial objects related to at least two images of multiple images is different; the second representation of at least two representations is a static view code rate; the static view code rate includes multiple images; and the spatial information of the spatial objects related to multiple images is the same. By adoption of the embodiment of the invention is advantaged in saving the transmission resources of the video data, improving the flexibility and the applicability of the videopresentation, and enhancing the user experience in viewing videos.

Description

technical field [0001] The invention relates to the field of streaming media data processing, in particular to a video data processing method and device. Background technique [0002] With the development and improvement of virtual reality (English: virtual reality, VR) technology, more and more applications for watching VR videos such as 360-degree viewing angles are presented in front of users. During the VR video viewing process, the user may change the viewing angle (English: field of view, FOV) at any time, and each viewing angle corresponds to a video stream of a spatial object. switch. [0003] In the prior art, VR panoramic video is divided into multiple code streams corresponding to multiple fixed spatial objects in the VR video preparation stage, and each fixed spatial object corresponds to a set of dynamic Adaptive streaming (English: dynamic adaptive streaming over HTTP, DASH) stream. When the user changes the viewing angle, the terminal selects one or more fi...
