Video Clip Delivery Using Hierarchical Temporal Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating and distributing high-quality video clips, such as those from live sporting events, are inefficient due to the delays caused by MPEG compression and uploading processes, which hinder rapid distribution and engagement.
Innovation Solution
A computer-implemented method that converts video feeds into a compressed format with a hierarchy of temporal resolution levels, allowing for quick uploading and playback, including the use of an electronic edit decision list to define editing operations, enabling fast and flexible video clip generation and distribution without relying on MPEG format files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If MPEG compression is used to generate video clips, then video quality can be maintained, but the processing time and distribution delay increase significantly
Solution Approach 1:
The video data is segmented into discrete packets that can be independently processed and transmitted. This allows parallel processing of multiple video segments simultaneously, reducing overall processing time while maintaining quality through selective decompression of only necessary frames for editing operations
Solution Approach 2:
Video data is pre-compressed into a format with hierarchical temporal resolution levels before editing occurs. This preliminary structuring enables rapid random access to specific time periods without requiring full decompression, allowing editors to quickly navigate and select clips while preserving original quality
2Ease of operation
If MPEG files are uploaded to servers for distribution, then video clips can be made available, but the upload time and network bandwidth consumption increase
Solution Approach 1:
The video stream is divided into smaller packets that can be uploaded and distributed independently. This segmentation enables parallel upload channels, reduces the impact of network failures, and allows receivers to process and display video segments as they arrive without waiting for complete file uploads
Solution Approach 2:
The system transmits video data at varying quality levels based on the specific needs of different segments and receiver capabilities. Full quality is transmitted only where necessary, while other areas use compressed representations, optimizing bandwidth usage while maintaining adequate quality for distribution purposes
3Adaptability or versatility
If multiple versions of video clips are generated for different devices, then compatibility is improved, but the processing complexity and time increase
Solution Approach 1:
The system dynamically adapts video delivery based on receiver characteristics and network conditions. Rather than pre-generating all possible versions, the system adjusts compression levels, resolution, and frame rates in real-time based on feedback from the receiving device, reducing processing complexity while maintaining broad compatibility
Solution Approach 2:
A single universal video packet format is designed that can be efficiently decoded by multiple device types. This universal format incorporates hierarchical temporal resolution that naturally adapts to different playback requirements, eliminating the need for separate processing pipelines for different devices
4Productivity
If video feeds are made publicly available, then viewer engagement increases, but the risk of unauthorized redistribution and piracy increases
Solution Approach 1:
The system employs dynamic parameter changes in video encoding, including variable bitrate, resolution adjustment, and frame rate modification based on authentication status. Authorized users receive high-quality streams with full features, while unauthorized access automatically receives degraded quality or blocked access, reducing piracy value without impacting legitimate viewership
