Dynamic Video Content Segmentation for Personalized Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering online video do not effectively handle dynamic image changes, making it difficult to modify video content in real-time for different viewers while maintaining efficient compression and storage, as compression techniques eliminate similar data regions which complicates accurate image region modification.
Innovation Solution
A method involving a processor that compresses contiguous frames with modified content separately from unmodified content, allowing for efficient delivery by storing only changed sections and providing relative temporal position information, enabling dynamic content alteration without altering existing compression algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If video compression techniques are applied to eliminate similar data regions, then transmission and storage costs are reduced, but accurate image region modification becomes difficult
Solution Approach 1:
The patent applies preliminary action by pre-identifying and marking regions of interest (ROIs) in the video frames before compression occurs. These ROIs are tagged with metadata that preserves their location and boundaries through the compression process, enabling accurate modification later despite the lossy nature of compression. The ROIs are prepared and marked in advance so that when modification is needed, the exact regions can be located and altered without needing to fully decompress the video.
2Adaptability or versatility
If dynamic image changes are implemented to create viewer-specific content, then content personalization is improved, but compression efficiency deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the video content into distinct regions of interest (ROIs) that can be independently modified for different viewers. Instead of creating entirely different compressed video streams for each viewer, the system segments the video into modifiable ROIs and only compresses/transmits the unchanged portions. This allows multiple viewer-specific versions to be created from a single compressed base, maintaining compression efficiency while enabling content personalization.
3Adaptability or versatility
If contiguous frames with modified content are compressed separately from unmodified content, then modification flexibility is improved, but processing complexity increases
Solution Approach 1:
The patent applies merging by combining multiple contiguous frames that share the same ROI modifications into a single compressed data structure. Instead of processing and storing each frame separately with its own modification markers, the system merges consecutive frames that require the same modifications, reducing redundancy in the processing logic and data structures while maintaining the ability to apply modifications flexibly across multiple frames.

AI summary
A system and method is presented that segregates portions of a video file into distinct sections based on whether the sections contain original content or modified content. For each segment, portion, section or scene with modified content, a compressed file is created which includes at least one instance of a set of frames which includes modified content. For some sections there may be two or more versions of modifications. These alternative versions may be compressed as a single distinct file. This permits efficient edge caching of video files with modified content, for example for selective provision of alternative versions of the video file to various end users in a transmission efficient manner.
