Description

Technical Field

[0001] This utility model relates to the field of audio and video processing technology, specifically to an audio and video data interaction management device. Background Technology

[0002] Audio and video data interaction management is a comprehensive process involving the transmission, sharing, and use of data across different devices, platforms, or applications. Data interaction management refers to a series of planning, organizing, controlling, and monitoring activities undertaken to ensure the secure, efficient, and consistent transmission and sharing of data between different entities. It aims to reduce risks during data interaction, improve the efficiency and accuracy of data interaction, and simultaneously ensure data security and compliance.

[0003] For example, in the prior art, patent application number CN202211436077.4 discloses a big data-based intelligent interactive management system. The system's operation method includes importing information based on the application scenario of the IoT service platform, establishing a communication transmission channel, and potentially binding relevant transmission protocols. It then retrieves the camera module of the IoT service platform to collect the user's facial features and height / body shape characteristics. Based on existing facial recognition technology and these characteristics, it identifies and determines the user's age. The system also constructs an operation time interval table and a menu progress table in the background to collect and analyze user behavior. The menu progress table includes first-level, second-level, and third-level menus. While this system can identify the IoT service platform's installation scenario and regional division, and demonstrates good interactivity and practicality through its analysis of the operation time interval table and menu progress table, it still suffers from problems such as complex operation, inability to monitor system device operating status and abnormal conditions, inability to guarantee audio quality, and insufficient stability and reliability.

[0004] Traditional data management platforms rely on internet connectivity for their equipment and often only have a single management function, such as video processing or a specific application. Their processing capabilities are limited and their functions are singular. They require a large amount of hardware, software, and internet connectivity to operate, making them complex to use. Furthermore, they cannot monitor the system's operational status or any abnormalities when offline. Therefore, it is necessary to design a new hardware-based audio and video data interaction management device that can operate offline. Utility Model Content
