Video Stream Thumbnail Generation During Partial Packet Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems struggle with efficiently generating and depicting complex digital video streams, particularly in advanced broadcast standards like ATSC 3.0, due to high data volumes and compute-intensive processes, leading to resource spikes and inefficient utilization.
Innovation Solution
A mechanism is introduced to generate thumbnail images for video segments during partial reception, limiting concurrent generation based on available processing units and hardware limitations, ensuring smooth processor usage and optimal operator experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thumbnail images are generated for all video segments in real-time, then operator experience and monitoring efficiency are improved, but processor capability is overwhelmed causing resource spikes
Solution Approach 1:
The patent segments the thumbnail generation process by prioritizing only key frames (I-frames) over all video frames. This selective segmentation reduces the processing load while maintaining effective monitoring, as key frames contain sufficient visual information for thumbnail generation without requiring processing of all video segments.
Solution Approach 2:
The patent applies partial action by generating thumbnails only for key frames rather than all video frames. This partial processing approach provides sufficient monitoring capability without the excessive computational burden of processing every frame, thereby avoiding processor overload while maintaining effective operation.
2Reliability
If all video packets are processed to ensure complete data reception, then data integrity is maintained, but processing time and computational resources are significantly increased
Solution Approach 1:
The patent extracts only the essential information needed for monitoring from the complete video stream. By identifying and processing only key frames (I-frames) rather than all video packets, the system extracts sufficient visual data for thumbnail generation while discarding redundant information, thereby maintaining data integrity for monitoring purposes while significantly reducing processing time.
Solution Approach 2:
The patent applies partial action by processing only a subset of video packets (key frames) rather than the complete stream. This partial processing maintains sufficient data integrity for effective monitoring while dramatically reducing the time and computational resources required compared to processing all video packets.
3Loss of information
If complex data visualization is implemented to display all packet information, then monitoring completeness is improved, but system complexity and difficulty of detection increase
Solution Approach 1:
The patent extracts only the most visually representative information (key frames) from the complex video stream for display. This extraction creates simplified thumbnail images that convey essential monitoring information without requiring complex visualization of all packet data, thereby maintaining monitoring completeness while significantly reducing system complexity.
Solution Approach 2:
The patent creates simplified copies (thumbnails) of the video content using only key frames rather than displaying the complete complex data stream. These thumbnail copies preserve the essential visual information needed for monitoring while presenting it in a simplified, easily interpretable format that reduces system complexity and difficulty of detection.

AI summary
A method and apparatus is described. The method includes receiving a media stream, that includes a video segment, determining, while receiving the media stream, when a portion of the video segment that is capable of generating a thumbnail image has been received and generating a thumbnail image for the video segment using the portion of the video segment based on the determination, and providing the generated thumbnail image for display. The apparatus includes a network interface that receives a media stream, the media stream including a video segment, a video signal processor configured to determine when a part of the video segment that is capable of generating a thumbnail image has been received and generate a thumbnail image for the video segment when it if determined that the part of the received for the video segment has been received, and a display interface for providing the thumbnail image for display.
