Problems solved by technology

[0005] At present, there has been some research on how to store and encapsulate multi-view video data, but the existing multi-view video transmission signaling only considers the overall presentation effect of the data, and does not add support for encapsulation and transmission signaling for users to control the viewing angle change in real time

Embodiment 1

[0030] attached figure 1 Shown is a system architecture diagram based on free-view video consumption proposed by the present invention, which mainly includes the following parts:

[0031] 1. The shooting system for shooting at the shooting location.

[0032] The shooting system is composed of multiple shooting cameras with different viewing angles. Each shooting camera shoots the shooting scene to generate a video stream. It is transmitted to the server (cloud) through a communication network (such as 5G).

[0033] Second, the server side (cloud).

[0034] The server side receives and stores video streams from multiple perspectives transmitted by the shooting system.

[0035] In order to manage the video stream and facilitate subsequent use, two organizational structures for this information are defined:

[0036] One is the structure of a camera that captures multi-view videos:

[0037]

[0038] The second is to represent an initial viewing angle provided by the server...

Embodiment 2

[0083] Embodiment two is basically the same as implementation one, the difference is as follows:

[0084] After receiving the information of the target angle of view, the server side analyzes and determines and selects the shooting cameras that the target angle of view depends on, and after the server analyzes the parameter information of each shooting camera that the target angle of view depends on and the corresponding media data stream, it generates the video of the target angle of view data stream and transfer to the client.

[0085] The client renders and presents directly after decoding.

[0086] The invention provides a transmission method and a receiving and processing method based on free viewing angle video data, which can provide real-time variable ranges of viewing angles for selection when users consume video media content. Users can freely change the viewing angle when consuming video media, and can obtain video media content that meets user needs and free viewi...

Abstract

The invention discloses a free view angle-based video data transmission method and a free view angle-based video data receiving and processing method, which are used for freely switching a viewing view angle when a user watches a video, a plurality of cameras with different view angles are used for cooperatively shooting a plurality of generated video streams, and a server side provides a variable viewing view angle range for a client side; a user selects a target view angle which the user wants to watch, the server selects parameter information of each shooting camera dependent on the target view angle and a correspondingly generated video data stream and transmits the parameter information and the video data stream to the client, and the user carries out rendering presentation after analysis and calculation. According to the invention, the consumption demand of the client for the interactive free view angle video is realized, the data transmission efficiency is improved, and finally, better experience is brought to the user.

Description

technical field [0001] The present invention relates to the field of design and application of free-view video data encapsulation and transmission process, in particular, to a transmission method and receiving processing method based on free-view video data. Background technique [0002] With the rapid development of information technology, the traditional video consumption mode based on fixed viewing angles is becoming more and more mature. How to provide users with a more realistic, interactive, and more personalized visual communication experience has gradually become a development hotspot. The new type of visual communication provides users with an immersive real experience that is not limited by time, region, and real conditions through multi-camera collaborative shooting, real-time content generation, high-efficiency codecs, adaptive transmission systems, and interactive terminals. , but also bring unlimited space for new applications. [0003] The generation, encapsu...
