一种基于分层构件的智能电视驱动设计

In recent years, the function of smart TV is becoming more and more complex and diversified, more over, Android has big change every year. In order to meet the new needsm the chip manufacturers have to upgrade the chips very frequent. Chip manufacturers's SDK includes the drive for hardwares, and includes an abstraction layer to make the driver be called convenient by application, and supporting API (relative to the upper Android framework layer, generalized the three referred to as driver system). The bottleneck of driver system is how to make it quickly adapt to the emerging new applications. The early driver system of smart TV comes from set-top box or other HD/BD player. The driver system generally connect DEMUX, Decoder, Output with waterfall way to achieve a particular function, which makes it more relevant between modules.In the new application scenarios, the connections between modules are very flexible, and the types of data are varied. To maintain the driver system, manufacturers need to spend a lot of resources to modify the original system to meet the new requirements, but with the increase in the complexity of the system, this process will be more and more difficult. In this paper, we presents a smart TV driver system design, it based on component based development (CBD) , which make it be flexibly to meet the changes in application and middleware. Meanwhile, its internal components also use layered design structure, so that it can be applied in different chips. Through the practice of specific projects, it is feasible to shorten the period of project development and maintenance, and make the driver system versatility, scalability, reusability and robustness. .
