Introduction

Material cultural heritage constitutes an essential component of China's outstanding traditional culture, carrying the historical memory and cultural genes of the Chinese nation. With the rapid development of digital technology, broadcasting and television technology is playing an increasingly important role in the digital dissemination of material cultural heritage. In recent years, the state has attached great importance to the protection and inheritance of material cultural heritage, issuing a series of policy documents that emphasize intensifying dissemination efforts and encouraging new media platforms to undertake related communication work. Guided by these policies, broadcasting and television, as traditional media, have actively employed digital means to record, disseminate, and promote material cultural heritage. This study leverages the powerful network infrastructure of the national broadcasting and television backbone network and the cable TV network interconnection platform, combined with advanced digital technologies such as large models, artificial intelligence, and 3D visualization, to collect, store, and enable online-offline interaction of digital resources related to Chinese culture and tourism, including images, text, panoramas, and 3D models. Based on television-side display, users can access and watch digital cultural interaction applications anytime and participate in interactive experiences, enjoying personalized recommendations of cultural content from cultural agents, engaging in intelligent Q&A with cultural agents, and conveniently obtaining in-depth knowledge about cultural and tourism resources across the country.

1. Key Technologies in Broadcasting and Television for Digital Cultural Interaction Applications

Advanced digital technologies such as large models, intelligent voice, and 3D visualization are profoundly transforming the world. Large models, as critical milestones in AI development, refer to deep learning models with parameter scales exceeding hundreds of millions or even hundreds of billions, such as GPT and BERT. Their characteristics are remarkable: they possess high capacity to capture complex patterns and distributions; they offer versatility to support multi-tasking and multimodal learning; they also feature scalability, enabling them to complete specific tasks with minimal samples or unsupervised fine-tuning based on pre-training.

1.1 Large Model Capability Foundation

The large model capability foundation is the basic architecture and technical system that supports the operation, development, and application of large models. It provides comprehensive support for computing, storage, data processing, and algorithm optimization, encompassing capabilities in language understanding, text generation, knowledge Q&A, multimodal interaction, logical reasoning, mathematical ability, and code capability. This includes intelligent computing servers and full lifecycle tools supporting large models from training to publishing and integration into applications. These tools cover core functions such as model training, model fine-tuning, dataset management, model management, API management, and online testing to meet the needs of large model development, deployment, and application in different scenarios.

In the broadcasting and television field, the large model capability foundation's powerful data processing ability can handle massive amounts of data transmitted through cable television, including video and audio streams, enabling efficient parsing and processing of these complex and diverse streams simultaneously. It can accurately identify every frame in videos and analyze every note in audio, ensuring no critical information is missed during high-speed data transmission, thus laying a solid foundation for subsequent content analysis and processing. User behavior data is equally an indispensable source of important data in the cable television field. Through in-depth insights into user behavior, broadcasting and television operators can better understand user preferences, viewing habits, and consumption patterns. The large model capability foundation can collect and integrate user behavior data from various channels, including operation records on television terminals such as channel switching, program searching, pause and fast-forward, as well as interactive behaviors on related applications like program reservations, comments, shares, and favorites. It aggregates and cleans these scattered data, transforming them into structured information for in-depth analysis. For instance, by analyzing information such as frequently watched program types, viewing time distributions, and device preferences, operators can precisely grasp user needs and provide more personalized services.

The large model capability foundation also possesses efficient model inference speed capabilities. In the broadcasting and television field, users have extremely high requirements for service response speed, expecting instant feedback whether switching channels, searching for programs, or engaging in voice interaction. With its powerful model inference speed, the large model capability foundation can quickly respond to various user requests. When a user presses a button on the TV remote control or issues a command through a voice assistant, the large model capability foundation can parse and process the request in a very short time. It rapidly retrieves information matching user needs from the vast program database or quickly generates personalized program recommendation lists based on user history and preferences. When users search for programs, the large model capability foundation can perform semantic understanding and analysis of input keywords within milliseconds, then conduct precise matching in the massive program library and swiftly return relevant program information to users. This rapid response speed not only enhances user viewing experience but also improves user satisfaction and loyalty with broadcasting and television services. For some real-time application scenarios, such as interactive segments in live programs, the large model capability foundation's fast inference speed is even more critical.
