Filter Planner for Video and Audio Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video and audio editing systems lack an efficient method to manage and execute complex filter operations across different domains and hardware/software platforms, requiring users to manually select and implement filter functions, which can be cumbersome and inefficient.
Innovation Solution
A system comprising a filter stack, registry, planner, and executor that specifies, accesses, and executes filter operations on video and audio clips, utilizing a filter planner to generate a plan that optimizes the use of hardware and software filters, allowing transparent operation and selection of appropriate filter functions based on domain and protocol identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually select and implement filter functions for video and audio editing, then flexibility and control are improved, but operation complexity and time consumption increase
Solution Approach 1:
The system performs automatic filter planning and selection without requiring user intervention. The filter planner automatically analyzes the filter stack, queries the registry for available functions, and generates an optimized execution plan, allowing the system to serve itself rather than requiring manual user configuration
Solution Approach 2:
The filter registry pre-stores information about all available filter functions including their capabilities, parameters, and compatibility. This preliminary organization of filter information allows the planner to quickly generate execution plans without real-time analysis, reducing operation time
2Adaptability or versatility
If multiple filter functions are available for different hardware and software platforms, then adaptability is improved, but system complexity increases
Solution Approach 1:
The filter registry serves as a universal interface that manages multiple filter functions across different hardware and software platforms. It stores standardized information about various filter operations (fade, blur, transition, etc.) and their compatibility, allowing the system to adapt to different platforms without increasing user-facing complexity
Solution Approach 2:
The filter registry acts as an intermediary layer between the filter planner and the actual filter execution functions. It abstracts the complexity of multiple hardware/software filter options by providing a unified query interface, managing the diversity of filter implementations without exposing complexity to the planner or user
3Speed
If hardware filters are used for filter operations, then processing speed is improved, but compatibility and flexibility decrease
Solution Approach 1:
The filter planning system dynamically selects between hardware and software filter functions based on the specific operation requirements, available resources, and performance needs. The planner queries the registry to determine which filter functions are available in hardware versus software, and makes adaptive decisions about which to use for each operation in the filter stack
Solution Approach 2:
Different filter operations within the same filter stack can be assigned to different execution modes (hardware or software) based on their specific requirements. Hardware-accelerated filters are used for operations that benefit from speed, while software filters are used for operations requiring greater flexibility or parameter control, optimizing the overall system performance
Data Source
AI summary
A system for modifying video including a source of a filter stack specifying filter operations to be carried out on a video clip, a filter registry of filter functions including information on filter operations that can be carried out by the filter functions, and a filter planner that receives the filter stack and accesses the registry in order to generate a filter plan specifying filter functions to be used in carrying out the filter operations specified in the filter stack.
