Multimedia Middleware Metadata Service Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia middleware technologies face challenges in maintaining and managing service components, requiring reconfiguration and replacement of existing service components for adding new functions, which complicates the management of multimedia applications in mobile terminals.
Innovation Solution
A multimedia middleware apparatus and method using metadata to manage and control multimedia middleware service components, where metadata includes API information for structural organization, enabling easy addition, deletion, or change of services by identifying and applying service implementation codes through a service management section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service components are reconfigured and replaced to add new functions, then new multimedia services can be added, but the complexity of managing multimedia middleware increases
Solution Approach 1:
The patent introduces a metadata file as an intermediary between service components and the multimedia middleware management system. This metadata file contains structured information about service components including their identifiers, dependencies, and configuration parameters. The metadata serves as a mediator that automates the identification, selection, and configuration of service components, thereby reducing the complexity of managing multimedia middleware while enabling flexible addition of new services.
2Adaptability or versatility
If service components are reconfigured to add new functions, then new multimedia services can be added, but the difficulty of maintaining service components increases
Solution Approach 1:
The patent applies preliminary action by pre-defining and storing all necessary service component information in metadata files before the services are actually deployed or executed. The metadata files contain complete information about service components including their identifiers, dependencies, versions, and configuration parameters. This preliminary organization of information enables automated service component management, making maintenance easier as the system can automatically identify and manage service components based on the pre-prepared metadata without requiring manual reconfiguration.
3Adaptability or versatility
If existing service component files are replaced for new multimedia applications, then new services can be supported, but significant design changes are required in mobile terminals
Solution Approach 1:
The patent implements universality by creating a standardized metadata file format that can describe multiple types of service components and multimedia applications. The metadata structure uses universal elements such as service component identifiers, dependency relationships, and configuration parameters that can accommodate various multimedia services. This universal metadata framework allows the mobile terminal to support new multimedia applications without requiring significant design changes, as the same metadata-driven mechanism can handle different service types through a common management interface.
Data Source
AI summary
A multimedia middleware apparatus using metadata, a control method and a storage medium are provided which can receive metadata in multimedia middleware provided in a terminal, easily add/delete/change a service, and effectively maintain and manage middleware components. When an open multimedia terminal processes multimedia contents, a multimedia middleware service structure for expressing information of a name, configuration, version and application programming interface (API) update is configured in the form of metadata. Lists of standard and non-standard services of multimedia middleware are then generated and managed.
