Research on Multimodal Optimization of 5G Using Adaptive Bitrate Stream Algorithm

This study focuses on the technical challenges of multimodal interaction requirements in immersive tourism scenarios, and proposes a multimodal optimization system based on an adaptive bitrate stream algorithm. The system aims to provide users with high-quality immersive experience by intelligently allocating network resources and dynamically adjusting video bitrates, and ensure smooth interactive performance in multimodal interactive scenarios such as virtual reality (VR), augmented reality (AR), and speech recognition. In order to verify the effectiveness of the system, this paper designs a complete solution including algorithm modules and simulation models, and conducts comprehensive tests in combination with multimodal interactive scenarios. The experimental results show that under the 5G network environment, the system significantly optimizes the key performance indicators of immersive tourism.
