USB Recording Function Activation in Digital TVs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many users do not utilize the USB recording function in digital TVs due to their viewing habits, resulting in unnecessary patent fees for digital TV manufacturers, as the USB recording function is often activated by default.
Innovation Solution
A method and device that allow users to customize and activate the USB recording function by obtaining and matching activation keys, enabling users to activate the function only when needed, thereby reducing unnecessary costs for manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the USB recording function is activated by default, then the TV provides complete functionality, but users who do not use the function still incur patent fees
Solution Approach 1:
The patent implements a dynamic activation mechanism where the USB recording function transitions from a static default state to a user-controlled dynamic state. Users can activate or deactivate the function based on their actual needs through a remote control interface, allowing the system to adapt its functionality and cost structure to individual usage patterns.
Solution Approach 2:
The patent changes the activation state parameter of the USB recording function from a fixed default value to a user-modifiable variable. By introducing activation keys and remote control commands, the system allows users to change the functional state, directly linking functionality availability to actual user demand and reducing unnecessary patent fee payments.
2Loss of energy
If the USB recording function is deactivated by default, then users save on patent fees, but the function is not available when needed
Solution Approach 1:
The patent implements preliminary action by providing users with activation keys in advance and enabling them to activate the USB recording function at any time before actual use. The remote control interface allows users to perform the activation action beforehand, ensuring the function is ready when needed while maintaining cost savings when not in use.
Solution Approach 2:
The patent enables self-service by allowing users to independently activate or deactivate the USB recording function through the remote control without requiring technical assistance or complex configuration. The system provides a user-friendly interface where users can manage their own function activation status based on their needs.
3Loss of energy
If activation keys are required, then unnecessary patent fees are reduced, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism (activation keys and remote control interface) that mediates between the user and the USB recording function. This intermediary layer simplifies the user experience by providing a straightforward activate/deactivate workflow while managing the underlying complexity of patent fee calculations and function state changes.

AI summary
Disclosed is a method for customizing a USB recording function, which includes: judging whether the USB recording function corresponding to a program cache instruction is in an open state, on condition that the program cache instruction is acquired; if the USB recording function is in an un-open state, acquiring a first request key and obtaining a first activation key based on the first request key; and acquiring information at a WEB end according to the first request key, matching the first activation key with a second activation key acquired from the WEB end, and activating the USB recording function on condition that the first activation key is consistent with the second activation key. The present disclosure further provides a device for customizing the USB recording function and a computer readable storage medium.
