摘要: | Advancements are rapidly being made in mobile computing environments and context aware multimedia streaming services that are based on information about a user\'s context. This work proposes a Context-Aware Embedded Multimedia Presentation System (CEMP) that is based on the context vocabulary ontology to provide a formal explicit description of the multimedia information domain and the formal context process model. The designed context recognition and context representation reasoning mechanism can perform context classification to deliver multimedia services of the required quality. Additionally, the CEMP system includes an adaptation reasoning mechanism that identifies the best adaptation control when the context changes. However, context modification may cause a context conflict problem among multiple adaptation requirements and resource limitations. The CEMP system provides a conflict resolution mechanism that calculates the context\'s priority and the context weight to improve context conflict resolution results. |
