Description

Guide broadcasting system under meta-universe scene

Technical Field

The invention relates to the technical field of virtual reality, in particular to a broadcasting guiding system in a meta-universe scene.

Background

With the development and maturation of metauniverse technology, human activity scenes expand to metauniverse to become necessary trends, such as metauniverse singing, metauniverse weddings, metauniverse conferences, metauniverse games and the like.

Due to current technological, knowledge, equipment and other threshold constraints, not all people can participate in the metauniverse, and these activities present a barrier to the real world presentation. The presentation of the meta-cosmic activity to the real world is a necessary requirement for technical development, and is also a necessary requirement for the public of users (for example, the elderly can only watch the meta-cosmic wedding of grandmother through video playing devices such as televisions and mobile phones). The current living broadcast technology based on the meta universe is single and crude, only a certain person can output signals from a visual angle, the multi-position switching and the omnibearing watching are difficult to realize, and the effect of television living broadcast (such as spring and night and sports event) is difficult to achieve. How to display activities in the metauniverse to the real world in a more professional, comprehensive, rich and artistic way through a broadcasting guide way is a problem to be solved in the metauniverse development process.

The prior art has the following disadvantages:

1. at present, virtual reality, three-dimensional games and the like are similar to meta-universe scene picture broadcasting, generally, pictures of a plurality of user nodes are summarized on a certain device in a video stream mode, external hardware devices such as a switching table, a sound mixing table, communication devices and the like are needed, and hardware cost is high.

2. The broadcasting team often needs professional support, and the technical cost is high.

3. The guiding, shooting personnel and tools are distributed in the virtual world (on line) and the real world (off line) at the same time, so that the connection is complex and the efficiency is low. The remote receiving of the video stream by the guide device is to have delay interference, so that deviation of guide work occurs.

For example: the publication number CN107333172A discloses a method and a device for guiding a broadcasting system and electronic equipment, wherein the broadcasting system comprises a first terminal device, a mobile terminal and a server, and the method for guiding the broadcasting system comprises the following steps: a first application running on a first terminal device captures a video stream of the first terminal device; the method comprises the steps that a second application program running on the mobile terminal obtains identification information of first terminal equipment, and obtains a video stream of the first terminal equipment after connection is established between the second application program and the first terminal equipment based on the identification information; and responding to the user instruction, and transmitting at least one path of video stream to the server after the video stream is led to be broadcast. The invention has the problem of disadvantage 3.

4. At present, the living broadcast view angle of the meta-universe program is single, and professional guidance is lacked. For example, a football game, because of the intervention of broadcasting, explaining, high power lens, slow lens playback, etc., the television broadcasting can be more obvious than the live view, all functions in the metauniverse world can be further improved, the visual angle is not limited, and the live atmosphere is not weakened.

Description of the embodiments

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Examples

1-4, a broadcasting guiding system in a meta-universe scene is characterized by comprising an identity selection module, a connection establishment module, a sharing module and a communication module;

the identity selection module is used for selecting the identity by the user; the user may select a variety of identities, such as a director identity, a camera operator identity (hereinafter OB, and an Observer), a comment identity, and the like.

The connection establishment module is used for establishing connection between different identities through the identification information; the connection between different identities can be established through the identification information to form a system, the connection quantity is not limited in theory, for example, one director can be connected with 4 OBs to form a director system, one total director, two secondary directives, 12 OBs and one explanation director system can be formed, the director can invite the OBs to enter the system formed by the director system according to the requirements, and the OBs can also be applied to be added into the existing director system.

The OB can observe contents such as people, objects, scenes and the like in the meta-universe from any angle and any scene without obstacle, and the OB can enable an avatar photographer to interact with a performer and can also enable any activity in the meta-universe to be unaffected by using a 'ghost' view.

The sharing module is used for establishing a sharing view angle between connected members; the view angle shared by the system members (between the guide and the OB and between the OB and the OB) in a multi-screen display and switching manner can be used, for example, in order not to crash with the view angle of OB2, whether the view angle of OB2 is the same as that of the user or not can be confirmed firstly by OB1, and whether the guide can know whether the repeated OB view angle exists or not through a multi-screen picture.

And the communication module is used for carrying out communication among the members establishing connection. Communication can be established among the system members to carry out voice communication. And, the voice can be an intercom, or can be set as an external voice (such as an explanation and a voice-over) through sound channel management, and synthesized into the final program.

And the video processing module is used for carrying out a series of processing operations on the video, synthesizing a path of total signal and providing a final program output interface. The guide has guide authority, and through the virtual guide station function, the OB video is monitored, switched, special effects, sound channel switched, caption and other operations, one path of total signal is synthesized, and a final program output interface is provided, which is similar to the principle of a guide station in reality. It should be noted that, in the related patent technology, the broadcasting station generally processes the video stream signal, and the video stream is affected by bandwidth and noise in the transmission process, and there are delays and interferences, which cause operation errors. The system is a meta-universe internal logic business relationship, and the problems of transmission and interference are avoided.

The identity changing module is also arranged for changing the identity of the member; the identity of the system member can be changed, for example, in the process of using the system member, the number of OB pictures is too large, one director can not control all pictures easily, and one OB can be changed into a second director to be responsible for picture switching of one part.

The system is also provided with a member management module which is used for managing members and carrying out conventional functions such as adding, removing, renaming, voice disabling/all voice disabling, locking and the like on the members.

The system is also provided with a templated preset module which is used for storing and calling related settings of previous activities; some program guides are fixed in the aspects of machine arrangement, personnel configuration and the like, and can save and call related settings, so that the working efficiency is improved. For example, the evening party in the present year may call the relevant settings of the evening party in the last year; team a may invoke team B settings.

An open expansion interface is also provided. And supporting big data, artificial intelligence, semantic recognition, image recognition and other technologies. For example, OB is not necessarily a real person, so that the robot can automatically operate through semantic and image recognition, and labor cost is saved; big data can feed back the most popular pictures or identify sensitive pictures, so that the program quality is improved.

The system can be compatible with any metauniverse platform (program) through a plug-in form. The activities in the meta universe can be displayed more clearly and abundantly, and the bridge function is achieved in the meta universe and the real world.

The live broadcast cost and threshold can be reduced, the popularization is strong, and the integration of the universe and the industries such as self-media, games, education and the like is facilitated.

The method can realize that people can conduct guide broadcasting, and is more beneficial to the culture of television guide broadcasting talents.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
