Electronic Device for Automatic Digital Stream Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic control devices for broadcasting digital audio and/or video streams in passenger transport vehicles do not offer optimal user interaction, leading to inefficient management of stream switching.
Innovation Solution
An electronic control device with a reception module, acquisition module, detection module, and switching module that automatically or manually switches to preferred digital streams based on user profiles and detected events, such as unwanted content, stream endings, or user instructions, using metadata, automatic content recognition, and user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic switching mode is implemented, then switching speed and user interaction efficiency are improved, but user control and confirmation capability are reduced
Solution Approach 1:
The system dynamically adjusts the switching mode between automatic and manual based on user preferences and situational context. The switching module can operate in automatic mode for quick switching when users want efficiency, or switch to manual mode when users desire control and confirmation, making the system adaptable to different user needs and situations.
2Ease of operation
If manual switching mode is implemented, then user control and confirmation capability are improved, but switching speed and interaction efficiency are reduced
Solution Approach 1:
The system allows users to dynamically select between manual and automatic switching modes based on their current needs. When users want precise control, they can choose manual mode to confirm switches, and when they prioritize speed, automatic mode takes over, optimizing the balance between control and efficiency.
3Measurement precision
If user confirmation is required for switching, then switching accuracy and user intent verification are improved, but interaction complexity and time consumption are increased
Solution Approach 1:
The detection module performs preliminary analysis to identify triggering events and detect preferred digital streams before switching occurs. By pre-detecting the optimal switching opportunity and preparing the recommended stream, the system reduces the complexity of user confirmation while maintaining high switching accuracy, as users only need to confirm pre-analyzed recommendations.
4Productivity
If automatic stream detection and switching is implemented, then stream management efficiency is improved, but system complexity and processing requirements are increased
Solution Approach 1:
The system segments the stream management function into distinct modules: a reception module for receiving digital streams, a detection module for identifying switching opportunities and preferred streams, and a switching module for executing the transition. This modular segmentation improves stream management efficiency while organizing system complexity into manageable, specialized components.

AI summary
An electronic device for controlling the broadcasting of digital audio and/or video streams that includes: a module for receiving a list of upcoming streams able to be broadcast; a module for acquiring a set of profile(s) of a group of user(s); a module for detecting, among the received list and based on the acquired set, a preferred digital stream intended to be broadcast after a current digital stream; and a module for switching from a broadcast of the current stream to a broadcast of the preferred stream. The detection module is configured to detect an event triggering a switch to the preferred stream, and the switching module is configured to operate at least according to an automatic mode, where it is able to switch from the broadcasting of the current stream to that of the preferred stream upon the detection of the triggering event.
