Video Content Processing via Selective Macroblock Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for modifying video content by adding supplemental elements, such as overlays or icons, require processor-intensive full decoding and re-encoding of video streams, which is inefficient and time-consuming.
Innovation Solution
The method involves converting content data into an intermediate format based on context description data, allowing selective processing and modification of only the necessary portions of the content, thereby reducing the need for full decoding and re-encoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is completely decoded to spatial domain for modification, then content modification capability is improved, but processor load and time consumption increase significantly
Solution Approach 1:
The patent segments the video processing task by identifying and processing only the specific macroblocks that contain or are affected by the supplemental content, rather than decoding the entire video stream. This selective processing approach divides the work into manageable portions that can be handled efficiently.
Solution Approach 2:
The patent applies different processing quality levels to different regions of the video. Areas containing supplemental content receive full decoding and processing, while other areas maintain their compressed format. This local differentiation optimizes processor usage by focusing computational resources only where needed.
2Adaptability or versatility
If video content is completely decoded and re-encoded for each end-user, then content customization is improved, but time consumption and latency increase
Solution Approach 1:
The patent performs preliminary processing by pre-identifying and extracting the relevant macroblocks that contain supplemental content from the compressed video stream. This preliminary action prepares the data in advance, allowing rapid customization when content needs to be modified for different end-users without requiring complete re-decoding.
Solution Approach 2:
The patent applies partial action by processing only the necessary portion of the video data (macroblocks containing supplemental content) rather than the entire video stream. This selective processing significantly reduces the time required for content customization while maintaining the ability to deliver personalized content to end-users.
3Productivity
If supplemental content is added to compressed video without full decoding, then processing efficiency is improved, but modification precision deteriorates
Solution Approach 1:
The patent uses the compressed video data structure itself as an intermediary, allowing access and modification of specific macroblocks without complete decoding. The supplemental content is integrated into the compressed domain representation, enabling precise modifications while maintaining processing efficiency through selective macroblock manipulation.

AI summary
Methods and system for processing data are disclosed. One method can comprise receiving content data in a first format and context description data relating to a portion of the content data. The method may further comprise converting the portion of the content data to an intermediate format, and converting the portion of the content data from the intermediate format to a second format based at least in part upon the context description data.
