随着三网融合和下一代广播电视网的全面推进,智能电视成为融合终端领域新的研究热点,受到了科研、运营机构和生产部门的广泛关注.针对智能电视资源竞争、业务缺乏有效的QoS保障等问题,提出一种QoS驱动的智能电视资源管理框架(QDRMF),该框架以任务QoS模型为指导,具有多个用以保障任务QoS需求的组件模块,支持资源调度算法的动态加载与替换,并实现了基于优先级的资源调度算法,提高了系统对任务QoS需求的保障能力,最后通过实验验证了QDRMF的有效性.
With the triple play and the next generation of radio and television networks to promote the overall, smart TV has become a new research hotspot in the field of convergence terminal, by the scientific research, operations and production departments of widespread concern.For smart TV resources competition, the business lacks effective QoS Security and other issues, this paper proposes a QoS-driven intelligent television resource management framework (QDRMF). This framework is guided by the task QoS model and has multiple component modules to ensure the QoS requirements of the task. It supports dynamic loading and replacement of resource scheduling algorithms , And implements priority-based resource scheduling algorithm to improve the system’s ability to support QoS requirements. Finally, the effectiveness of QDRMF is verified by experiments.
