Interactive Multimedia Engine with Dynamic Scenario Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interactive multimedia systems are inflexible and require extensive reprogramming to adapt to different applications, leading to high maintenance costs and complexity, as they are designed with statically defined real-time media processing capabilities that cannot easily accommodate varying virtual scenes and user interactions.
Innovation Solution
A device and method featuring a real-time media processing engine with a virtual scenario description repository, parser/loader, and plug-in modules that allow for dynamic loading and creation of processing chains based on descriptor streams and triggering rules, enabling the creation of a wide range of interactive multimedia applications with a single engine by separating scenario and engine components and using a scenario programming language.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a statically defined real-time media processing module is used, then the system structure is simple and easy to implement, but the system cannot adapt to different applications and requires extensive reprogramming
Solution Approach 1:
The system is divided into a core engine with stable architecture and separate scenario-specific modules (virtual scene, media processing, interaction handling) that can be independently configured and replaced. This allows the core to remain simple while enabling adaptability through modular components.
Solution Approach 2:
The core engine is designed as a universal platform that can handle multiple different applications and scenarios through configuration rather than code changes. The same engine core supports diverse virtual scenes, media types, and interaction modes by loading different scenario modules.
2Adaptability or versatility
If the system is designed with fixed processing capabilities, then development and maintenance are easier, but any adaptation to new applications requires extensive reprogramming
Solution Approach 1:
The system transitions from static fixed capabilities to dynamic configurable capabilities. The core engine dynamically loads and executes scenario-specific modules based on configuration files, allowing the system behavior to change without modifying the core code structure.
Solution Approach 2:
Scenario-specific configurations and modules are prepared in advance as separate files or modules that can be loaded into the core engine. This preliminary preparation allows quick adaptation to new applications by simply loading pre-configured scenario packages rather than reprogramming.
3Adaptability or versatility
If extensive reprogramming is required for different applications, then the system can be highly customized, but maintenance costs and complexity increase significantly
Solution Approach 1:
By segmenting the system into a maintainable core engine and replaceable scenario modules, maintenance is confined to the stable core while scenario customizations are isolated in separate configuration files or modules that do not affect the core maintenance burden.
Solution Approach 2:
Scenario configurations are stored as external files or modules that can be copied, duplicated, and modified without affecting the core engine. This allows multiple applications to share the same core while having their own independent configuration copies.
4Productivity
If a generic core engine is used for multiple applications, then distribution and installation are simplified, but the engine must support a wide variety of scenarios
Solution Approach 1:
The core engine is designed as a universal platform with built-in support for multiple scenario types through configuration rather than code. A single core binary can be distributed once and will support diverse virtual reality setups by loading appropriate scenario modules from configuration files.
Solution Approach 2:
Configuration files serve as intermediaries between the generic core engine and specific application requirements. These files translate diverse scenario needs into a standardized format that the universal engine can process, enabling wide versatility without requiring engine modification.
