Content Playback Authorization for Switching Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content playback devices often unintentionally stop or switch to another content item due to user operation errors or automatic updates, leading to unwanted content changes during remote viewing.
Innovation Solution
A content playback device with a communication unit, display unit, and input unit, equipped with a content playback authorization determination unit that assesses the need for user confirmation before switching content, ensuring that the user is prompted for authorization before playing acquired content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the content playback device automatically plays acquired content without user confirmation, then the productivity is improved, but the reliability deteriorates due to unintentional content switching
Solution Approach 1:
The system implements a feedback mechanism by displaying a confirmation screen that requests user input before automatically playing acquired content. The content playback authorization determination unit receives feedback from the user through the input unit and adjusts the playback authorization accordingly, thereby preventing unintentional content switching while maintaining efficient automatic playback when authorized.
Solution Approach 2:
The system performs a preliminary action by displaying the content playback confirmation screen before executing the automatic playback of acquired content. This preliminary step asks the user for authorization to switch from the currently displayed content to the acquired content, ensuring that the automatic playback only occurs when the user intentionally approves.
2Reliability
If the content playback device displays a confirmation screen for every content switch request, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The content playback authorization determination unit operates autonomously by automatically determining whether to display the confirmation screen based on the playback instruction received from the control device. It self-manages the authorization process, handles user input through the input unit, and controls the playback switch without requiring complex external intervention, thereby maintaining reliability while avoiding excessive system complexity.
3Productivity
If the content playback device continuously monitors for content updates, then the productivity is improved, but the energy consumption increases
Solution Approach 1:
The system employs periodic action by monitoring for content updates at specific intervals rather than continuously. The content playback authorization determination unit checks for new content instructions from the control device periodically, allowing the device to maintain responsive content update detection while reducing energy consumption compared to continuous monitoring.

AI summary
A content playback device includes a communication unit which communicates with a control device; a display unit which displays content; an input unit which accepts input; and a content playback authorization determination unit which determines whether to switch from content being displayed to acquired content, wherein the content playback authorization determination unit determines whether it is necessary to acquire an instruction as to whether to switch from the content being displayed to the acquired content, and when the content playback authorization determination unit acquires an authorization instruction or determines that it is not necessary to acquire the instruction, the content playback authorization determination unit switches from the content being displayed to the acquired content, and when the content playback authorization determination unit acquires a rejection instruction, the content playback authorization determination unit causes the display unit to continue display of the content being displayed.
