Television Automatic Demo Video Playback via External Storage Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for playing demo videos on televisions fail to effectively showcase the display advantages of television products, as they often require manual operation and do not automatically detect and play customized demo videos from external storage devices.
Innovation Solution
A method and system that automatically detect external storage devices, search for demo video files with preset names or formats, and start playing them without manual intervention, allowing for cyclic playback and integration with timer-based operations to manage user interactions and mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a uniform video signal is played on televisions in shopping centers, then the operation is simple and standardized, but the display advantage of the television cannot be effectively presented
Solution Approach 1:
The system performs preliminary actions by automatically detecting external storage devices and searching for demo video files with preset names before playback is requested. This automation eliminates manual operation complexity while enabling effective display presentation through customized demo videos.
Solution Approach 2:
The television system serves itself by automatically detecting connected external storage devices, searching for appropriate demo video files, and initiating playback without user intervention. This self-service mechanism resolves the contradiction by maintaining operational simplicity while achieving effective display presentation.
2Ease of operation
If manual operation is required to play demo videos, then the system operation is straightforward, but the user experience and efficiency are reduced
Solution Approach 1:
The system performs preliminary detection of external storage devices and searching for demo video files before playback is needed. This preliminary automation eliminates the time loss associated with manual operations while keeping the interface straightforward for users who may want to intervene.
Solution Approach 2:
The television system automatically detects external storage devices, searches for demo video files with preset names, and initiates playback without requiring user actions. This self-service approach eliminates manual operation time loss while maintaining operational straightforwardness.
3Productivity
If customized demo videos are played, then the display advantage is effectively presented, but the system complexity increases
Solution Approach 1:
The system performs preliminary detection and file searching automatically, which adds complexity to the backend but keeps the user interface simple. This preliminary automation enables customized demo video playback that effectively presents display advantages without requiring complex user interactions.
Solution Approach 2:
The television system automatically manages the complexity of detecting external storage devices, searching for customized demo video files, and initiating playback. This self-service mechanism enables effective display presentation through customized content while hiding system complexity from users.
4Extent of automation
If automatic detection and playback is implemented, then user experience is enhanced, but the device complexity increases
Solution Approach 1:
The system implements preliminary automatic detection of external storage devices and searching for demo video files with preset names. This preliminary automation enhances user experience by eliminating manual steps while concentrating system complexity in the background detection and search mechanisms.
Solution Approach 2:
The television system automatically detects connected external storage devices, searches for appropriate demo video files, and initiates playback without user intervention. This self-service automation enhances user experience while managing system complexity through automated background processes.

AI summary
The disclosure discloses a method for playing a demo video on a television and a television so as to play the demo video on the television automatically. The method includes: detecting whether there is an external storage device connected with the television; searching an external storage device connected with the television for a demo video file with a preset file name and in a preset file format upon detection of the external storage device; and starting a player to read and play cyclically the demo video file stored in the external storage device when the demo video file is searched.
