Objective: With the advancement of globalization and the progress of science and technology, communication between people of different cultural backgrounds has become increasingly frequent. Cross-cultural communication has become an increasingly common phenomenon in today's world, involving the collision and intermingling of different cultural backgrounds, values, languages and customs. In this process, cross-cultural context has become an inevitable part of people's lives. In this context, people from different cultural backgrounds need to understand, respect and adapt to each other's cultural differences. These differences include not only language, customs, social etiquette and other aspects, but also values, ways of thinking, behavioral norms and other aspects. Therefore, in the cross-cultural context, the dissemination of local cultures across countries is of great significance. By transmitting native cultures to a wider range of people, it can enhance people's knowledge and understanding of native cultures in different places, and thus improve their sense of identity and cohesion. At the same time, the transmission of local culture in the cross-cultural context also helps to promote the exchange and understanding between different cultures, and promote the development of the diversity of world culture. Virtual Reality (VR) technology as a computer simulation system that can experience the virtual world, through the technology virtual and reality combined with each other, with immersive, interactive features into the audio-visual arts, for the dissemination of local culture provides a new way. Audiovisual arts is an art form that uses sound and picture as the means of expression and visual and auditory perception. It includes movies, TV dramas, TV variety shows, dances, dramas and other types. Through the organic combination of picture and sound, it creates artistic images with a sense of time and space and a sense of dynamics, which directly affects the audience's visual and auditory senses and thus produces a unique artistic effect. In the radio and television industry, the innovative integration of VR technology with audiovisual arts brings a new immersive experience by simulating human audiovisual perception, making users feel as if they were immersed in a virtual, three-dimensional, audiovisual environment with a sense of reality. In the meantime, in VR audiovisual arts, the audience can also interact with the virtual environment, and through their own perception and experience to stimulate unlimited imagination and creativity. In the figurative presentation of local culture, VR audiovisual arts in the radio and television industry can be delivered to the audience in a more realistic and vivid way, so that the audience can understand and perceive the history, traditions and customs of the local culture in a more in-depth way. Compared with traditional audiovisual arts, this immersive and in-depth experience can enhance the audience's cognition and perception of local culture, and improve their sense of identity and cohesion. Methods: This experiment adopts the qualitative analysis method to research and analyze the audience effect of VR audiovisual arts in the form of in-depth interviews. The topic of the in-depth interview focuses on the VR cultural variety show "Poetry and Painting of China", which won the "Asia-Pacific Broadcasting Television Union Award", and discusses the communication effect and influence of the program among the audience groups in a specific and in-depth manner. Ten domestic scholars and experts in related fields were selected for the study, and these experts' fields of study include art, culture, media, etc., to ensure that the research results have interdisciplinary depth and breadth. And all of them are audiences who have watched the program and have rich experience and unique insights in cultural communication and artistic expression, providing rich information for the in-depth interviews. The whole interview content centered on the research theme of the communication effect of the VR program "Poetry and Painting of China" on local culture, and five related questions were designed to explore the actual communication effect of local culture through VR audiovisual arts in the audience group. Results: Through in-depth interviews with ten experts and scholars, it can be found that the VR audiovisual program "Poetry and Painting of China" has achieved a good effect of local culture dissemination among the audience. Specifically, the program brings audiences into an immersive Chinese traditional culture scene through VR technology, which immerses them in the unique charm of Chinese traditional culture. Meanwhile, the program has also made some breakthroughs in cultural inheritance and innovation, allowing the audience not only to be satisfied with the artistic form, but also to gain a rich harvest in terms of cultural knowledge, and to have a deeper understanding and knowledge of the characteristics and connotations of Chinese poetic and pictorial culture, which in turn stimulates the audience's awareness of cultural inheritance and cultural self-confidence. However, VR audiovisual programs still have some deficiencies in the dissemination of local culture, such as the limited level of technology, cross-cultural communication barriers, and limited dissemination channels that still need to be improved. In response to these problems, experts also put forward some specific suggestions, such as increasing R&D efforts on VR technology, expanding the scope of dissemination by utilizing multiple channels, and attracting audiences at different levels in content production, with a view to providing some references and help for VR audiovisual programs in disseminating local culture. Conclusions: This study finds that VR audiovisual arts is of great significance to the communication effect of local culture in cross-cultural context. Through the integration with local culture, VR audiovisual arts can not only enhance the audience's sense of cultural identity, promote cultural dissemination and inheritance, facilitate cross-cultural communication and understanding, and enhance the national image, but also expand domestic and international cultural communication channels. Therefore, we should fully recognize the potential and role of VR audiovisual arts in the dissemination of local culture. In addition, there are still some existing problems that need to be noticed and improved, such as limited technical level, cross-cultural communication barriers, limited communication channels and other deficiencies in the process of VR audiovisual art's dissemination of local culture in the cross-cultural context. In this regard, this art form will also be actively explored and applied in the future to promote the inheritance and development of local culture, advance global cross-cultural communication and exchange, and contribute to the prosperity and development of world culture.
