Active Region Frame Playback for Smaller Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media content playback on smaller devices, such as smartphones, can be difficult due to the smaller screen size, which may not adequately display the action or important portions of the content, leading to a suboptimal viewing experience.
Innovation Solution
The use of active region data by media servers to prioritize and display only the important areas of an image frame, allowing viewer devices to 'zoom' in on these regions, ensuring that the primary action is prominently displayed on smaller screens, while larger devices can show the full frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the full image frame is displayed on smaller devices, then the complete content is shown, but the important portions are difficult to view clearly
Solution Approach 1:
The patent segments the image frame into multiple regions with different priorities, identifying and extracting the active region (highest priority) from less important regions. This segmentation allows the system to focus display resources on the most critical content areas, enabling clear viewing of important portions even on smaller screens by displaying only the high-priority active region.
2Loss of energy
If the full image frame is transmitted to all devices, then complete content is available, but bandwidth is wasted on devices that cannot display it properly
Solution Approach 1:
The patent applies local quality by transmitting different quantities of image data to different devices based on their specific characteristics. Small devices receive only the active region data (higher quality for critical content), while large devices receive the complete frame. This localized adaptation optimizes bandwidth usage by avoiding transmission of redundant data to devices that cannot utilize it, while maintaining device compatibility through selective data delivery.
3Ease of operation
If the entire image frame is displayed on small screens, then all content is visible, but the primary action is not prominently displayed
Solution Approach 1:
The patent extracts the active region (primary action area) from the complete image frame and transmits it separately as prioritized data. Small devices display this extracted active region prominently, ensuring the primary action is clearly visible. The extraction process identifies coordinates and dimensions of the active region, allowing it to be displayed in full detail on small screens without being diluted by less important surrounding content.

AI summary
Techniques are described for playing back a portion of an image frame of media content. The playback can be based on characteristics of the viewer device and active region data indicating important areas of the image frame.
