Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data communication systems with limited computing resources struggle to decrypt and process encrypted video data, leading to performance degradation, as decryption and video parsing require significant computational resources.
Innovation Solution
The system segments video data into uniform segments with embedded segmentation data elements, allowing devices to identify and process segments without decryption, leveraging the non-encrypted MPEG TS header to store segmentation points, thus reducing processing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If decryption and video parsing are performed on devices with limited computing resources, then the data can be processed, but the system performance degrades due to significant computational resource requirements
Solution Approach 1:
The patent segments video data into multiple data segments with uniform size, where each segment contains a portion of the encrypted video content. This segmentation allows receiving devices to process only the necessary segments without decrypting and parsing the entire video stream, thereby reducing computational resource requirements and improving system performance while maintaining the capability to handle encrypted video data.
2Loss of information
If encrypted video data is communicated without segmentation, then data security is maintained, but receiving devices must perform extensive decryption and analysis which requires significant computational resources
Solution Approach 1:
The patent applies preliminary action by segmenting the encrypted video data into uniformly sized segments before transmission. Each segment is properly formatted and can be independently processed by receiving devices. This pre-segmentation eliminates the need for receiving devices to perform extensive decryption and parsing operations on large amounts of data, significantly reducing computational resource consumption while maintaining data security through encrypted transmission.
3Productivity
If video data is segmented into uniform segments with segmentation data elements, then processing requirements are reduced, but the device complexity increases due to segmentation and reassembly operations
Solution Approach 1:
The patent introduces segmentation data elements as intermediaries that accompany each video data segment. These elements contain metadata such as segment sequence numbers, timestamps, and length information that facilitate efficient processing and reassembly. The intermediary segmentation data elements standardize the segment format, enabling receiving devices to process segments uniformly without complex customization, thereby improving processing efficiency while managing device complexity through standardized operations.
Data Source
AI summary
A data processing system receives video data from a data source and separates the video data into multiple video data segments. Each of the multiple video data segments are substantially the same size. The system generates a data segmentation element associated with each video data segment. The data segmentation element describes content in the associated video data segment. Each video data segment and the associated data segmentation element are communicated to a destination device.
