The Design And Implementation Of IGRS And UPnP Supported DMA-SDK And Its Application

With development of 3C integration technology, consumer electronic products are more and more popular, and new products continue to appear. In recent years, product based on home networking has also been a rapid developing. Many domestic or international standards organization has come out. In China, UPnP standard and IGRS standard affect home media application deeply. As the ever-changing consumer electronic products, and therefore the response speed of new applications, and the efficiency of product developers, it is particularly important. This paper focuses on digital media adapter (DMA) related applications, and brings forward the IGRS and UPnP DMA-SDK. Developing DMA applications based on the SDK, developer can flexible configure, reuse modules provided by SDK efficiently. As a result, developer can focus on GUI and some special need modules, thus greatly improving the efficiency of DMA application developing. Our works in this paper are showed as follow:1. Project background, there are including the developing of 3C integration; anaylsis of the common features and difference of domestic and international home standards organization; and the developing of UPnP and IGRS. Then survey the research about digital media application about UPnP and IGRS. On this basis, illustrate the significance of the project of this paper.2. IGRS and UPnP analysis, there are including standard compositon; analysis about IGRS and UPnP protocol stack SDK. And then focuses on study of its AV Application Framework. And then illustrates the concept about DMA.3. The design and implementation of the DMA-SDK, there are including cross-platform common tools SDK, IGRS-DMA SDK, UPnP-DMA SDK, Http file accessing SDK, Mp3 music player SDK, and dual-protocol software framework. This article first describes the overall relevance and dependencies of each sub-SDK, and then illustrates the design and implementation of sub-SDK's core modules and feature one by one.4. Dual Protocol DMA-SDK's application, Major research on SDK's python usage and application of dual-protocol digital photo frame (DPF). Analyze the design and implementation of DPF to reflect the DMA-SDK's ease of use, and the advantages about development based on the DMA-SDK. 5. DMA-SDK testing, according to each sub-SDK's major functions and operations, we design the corresponding test program and test cases. The DMA-SDK is proved the correctness, fault tolerance and stability.
