Abstract

The invention provides a 360-degree video caching method and device. According to the method, an ST-LSTM model is used for modeling the popularity of 360-degree video content from a time-space angle, an LSTM model is used for modeling the viewing angle of a 360-degree video from a time angle, and then the ST-LSTM model and the LSTM model are used for predicting the popularity of the 360-degree video content and the viewing angle of the 360-degree video respectively. According to the popularity of the predicted 360-degree video content and the viewing angle of the 360-degree video, an equilibrium solution of a joint optimization model is calculated and deduced through an evolutionary game by combining an established cache node resource scheduling and collaborative cache optimization algorithm, and finally an optimal cache result is obtained. The negative influence that 360-degree video transmission occupies a large amount of bandwidth can be reduced, the network delay and the equipment energy consumption are reduced, and the network data processing rate is improved.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, and in particular, to a 360-degree video caching method and device. Background technique [0002] As a key field of the new generation of information and communication technology, virtual reality (VR) and augmented reality (AR) provide a fully immersive user experience, and have formed a relatively wide range of industries, military, medical, aerospace, education, entertainment and other fields. Exploring applications, also receiving attention from the research and industry communities. The application of VR / AR technology in virtual assistants, simulation teaching, urban planning, etc. is gradually changing the way humans interact with the digital world. Some experience venues and theme parks are increasingly valued by the market with their novel business models . According to Cisco's Visual Networking Index, traffic generated by VR / AR applications will increase 12-fold from 201...
