Description

Technical Field

[0001] This utility model relates to the field of set-top box technology, specifically to a remote connection circuit for an Android set-top box device. Background Technology

[0002] With the widespread use of smart terminal devices, Android set-top boxes, as important terminal devices for home entertainment and service access, are becoming increasingly complex in function and diversified in application scenarios. During product development and testing, especially when prototypes are delivered to customers for field testing, development teams often need to perform real-time debugging and troubleshooting on remotely deployed Android set-top box devices. However, due to factors such as dispersed device deployment locations, complex network environments, and varying user skill levels, traditional local debugging methods are no longer sufficient to meet the needs of efficient technical support.

[0003] Currently, Android application debugging primarily relies on connecting to a development computer via USB cable and using ADB (Android Debug Bridge) tools to perform operations such as log capture, application installation, and debugging. However, this method requires the device to be physically close to the debugging host and demands a certain level of technical expertise from the user, making it difficult to implement in remote customer scenarios. Furthermore, some manufacturers have attempted to implement wireless ADB debugging (ADB over Wi-Fi) via a local area network, but limitations imposed by the customer's on-site network configuration (such as NAT and firewall policies) typically prevent penetration to the public network, resulting in significant difficulties for remote access.

[0004] On the other hand, existing remote control solutions mostly rely on pre-installing dedicated client software on the device and using cloud services to relay remote desktop or screen projection. While such solutions can achieve the goal of remotely viewing the device interface to a certain extent, they have the following shortcomings: First, they depend on the support of the device's operating system, requiring prior integration of the SDK or modification of the system source code; second, they are subject to customer network policy restrictions, making it difficult to guarantee a stable connection; and third, the deployment process is complex and unsuitable for plug-and-play rapid support scenarios. Therefore, how to quickly connect Android set-top box devices to the public network using network penetration tools, ensuring that technicians can easily access and debug the devices, has become a pressing technical challenge.
