Video Interpolation Indicator for Source-Sink Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video source and sink devices often perform overlapping and potentially inferior temporal interpolation video processing, making it difficult to distinguish and manage interpolated video content, leading to inconsistencies in video quality.
Innovation Solution
Incorporating a method to interpolate source video content, generate a video signal with both interpolated and non-interpolated content, and include indicators to distinguish between the two, allowing video sink devices to redo or undo interpolation for improved quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If temporal interpolation video processing is performed by video source devices, then video content can be converted between formats and frame rates, but the video quality may deteriorate due to inferior algorithms and it becomes difficult to distinguish interpolated from original content
Solution Approach 1:
The patent introduces an intermediary indicator (such as a flag or metadata) that is embedded in the video signal to mark temporally interpolated content. This intermediary element allows the video sink device to identify and differentiate between original and interpolated content, enabling selective processing while maintaining format conversion capabilities.
Solution Approach 2:
The patent segments the video signal by marking specific portions as temporally interpolated through the use of indicators. This segmentation allows the video sink device to process different segments differently - preserving original quality where possible and selectively applying or removing interpolation based on the marked segments.
2Adaptability or versatility
If temporal interpolation video processing is performed by both video source and sink devices, then format conversion can be achieved, but device complexity increases and processing efficiency decreases
Solution Approach 1:
The patent implements a feedback mechanism where the video source device provides indicators about the temporal interpolation status of the video signal to the video sink device. This feedback allows the sink device to adjust its processing accordingly, avoiding redundant interpolation operations and reducing overall system complexity.
Solution Approach 2:
The video source device performs preliminary action by marking the video signal with indicators before transmission. This preliminary marking enables the video sink device to make informed processing decisions without needing to perform complex analysis, thereby reducing the processing burden on the sink device.
3Stability of the object's composition
If temporal interpolation is applied to improve video smoothness, then playback quality may improve, but the ability to perform accurate video processing and analysis deteriorates
Solution Approach 1:
The patent uses a form of 'state change' indication by embedding metadata flags that visually or programmatically distinguish interpolated content. This allows processing systems to identify and handle interpolated content differently, preserving accuracy for analysis while maintaining smoothness for playback.

AI summary
Spatial or temporal interpolation may be performed upon source video content to create interpolated video content. A video signal including the interpolated video content and non-interpolated video content (e.g. the source video content) may be generated. At least one indicator for distinguishing the non-interpolated video content from the interpolated video content may also be generated. The video signal and indicator(s) may be passed from a video source device to a video sink device. The received indicator(s) may be used to distinguish the non-interpolated video content from the interpolated video content in the received video signal. The non-interpolated video content may be used to “redo” the interpolation or may be recorded to a storage medium.
