Embedding DVE in Graphics Modeling for Real-Time Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Digital Video Effects (DVE) systems for live broadcast are limited by fixed parameters, restricting the types of effects that can be created and requiring skilled graphics artists for non-real-time content creation, which hinders rapid changes and increases production costs.
Innovation Solution
The User Enhanceable DVE (UE-DVE) embeds DVE functionality within a 2D and/or 3D graphics modeling system, allowing users to introduce new model elements and control parameters interactively, using a dynamic data structure and description language to create and modify effects in real-time, enabling true 3D modeling and expanded creative possibilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional DVE systems with fixed parameters are used, then real-time broadcast capability is maintained, but the types of effects that can be created are limited and require skilled graphics artists
Solution Approach 1:
The patent combines DVE functionality with a 3D graphics modeling system into a unified platform. This merging allows broadcast technicians to access both real-time video effects capabilities and 3D modeling tools within a single system, enabling creation of complex effects that were previously impossible with traditional fixed-parameter DVE systems while maintaining real-time broadcast capability.
Solution Approach 2:
The system transitions from fixed, static parameters to dynamic, user-controllable parameters. Users can interactively adjust parameters in real-time and introduce new model elements, allowing the system to adapt to diverse effect requirements without requiring pre-programmed fixed parameters, thus significantly expanding the types of creatable effects.
2Adaptability or versatility
If pre-built video effects are used, then complex effects can be created, but production time increases due to offline rendering requirements
Solution Approach 1:
The system performs preliminary setup of 3D models and parameters that can be quickly adjusted and rendered in real-time. By preparing the graphical model structure in advance with controllable parameters, the system enables rapid effect creation and modification during broadcast without requiring time-consuming offline rendering, thus reducing production time while maintaining effect complexity.
Solution Approach 2:
The patent replaces the traditional offline rendering mechanical process with real-time computational rendering enabled by modern graphics hardware. This substitution allows complex 3D effects to be generated and modified in real-time during broadcast, eliminating the time delay associated with offline rendering while maintaining high effect complexity.
3Ease of operation
If traditional DVE systems are used, then real-time control is maintained, but creative possibilities are restricted to factory-created parameters
Solution Approach 1:
The system provides universal control capabilities that work across multiple effect types and 3D model elements. A single set of interactive parameter controls can manipulate various aspects of 3D models, lighting, cameras, and video effects, giving broadcast technicians versatile creative control without requiring separate specialized systems, thus expanding creative possibilities while maintaining ease of real-time operation.
Solution Approach 2:
The system enables broadcast technicians to directly create and modify complex 3D effects without requiring assistance from skilled graphics artists. By providing intuitive real-time controls and a user-friendly interface to the 3D modeling system, technicians can independently adjust parameters, introduce new model elements, and create custom effects, making the system self-sufficient for diverse creative needs.
