Video data processing method of holographic fan screen

Abstract

A video data processing method of a holographic fan screen comprises the following steps: 1, a GPU (Graphics Processing Unit) of the holographic fan screen is programmed, a plurality of groups of animation templates is made and each group of animation templates is encoded; 2, terminal equipment selects original 2D characters or pictures, corresponding animation template codes and video playing parameters to form a data packet and transmit the data packet to the holographic fan screen; 3, after receiving the data packet, the holographic fan screen analyzes corresponding 2D text or picture, animation codes and video playing parameters; 4, the holographic fan screen takes 2D characters or pictures as display objects, loads animation templates with corresponding numbers, and renders and outputs 3D animation in real time according to given video playing parameters; and 5, a user can interact with the holographic fan through terminal equipment. According to the processing method, the transmitted data volume is greatly reduced, the workload and cost of customers are reduced, the problem of distortion is avoided, diversified display is realized, and interactive operation is realized.

Description

technical field [0001] The invention relates to a video data processing method, in particular to a video data processing method of a holographic fan screen. Background technique [0002] The holographic fan screen is a new type of advertising display device. Its main advantages are low energy consumption, cool effect, full sense of technology, and the display effect is higher than that of traditional advertising machines. At present, in addition to displaying general static text and patterns, the holographic fan screen can also display dynamic text and patterns, that is, video display. [0003] In the process of video data transmission, the existing holographic fan screen generally makes a video of 3D text or pictures with a black background, and then transmits the video to the audio and video codec of the holographic fan screen, and finally decodes and plays it. [0004] However, the above-mentioned processing method has the following problems: 1. The data volume of the vi...

Problems solved by technology

[0004] However, the above-mentioned processing method has the following problems: 1. The data volume of the video is huge, and the transmission process is slow. Even if the video is compressed in the prior art, the adopted The compression methods are all lossy compression, and the display has a certain degree of distortion; 2. Since the video played by the holographic fan screen is the data information that has been recorded by the terminal, the user cannot interact with the holographic fan screen, and the flexibility of the display style is small
