| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 105 === With the progress of technology, the development of television has been greatly changed from the original cable transmission, analog signal to today's wireless transmission and digital signals. By the popularity of Set-Top box, the Digital TV has become the source of free messages for people. The advantages of digital broadcasting can transmit a variety of different information and will not be limited by time and space. It can also be used on different platforms. In addition to simple TV channels, the digital broadcasting can even add interactive content, such as the weather and important laws. Each kinds of the messages can be transmitted through the digital broadcast to the public.
In this paper we use the ISB293 STB development board provided by Aonvision Technology Corporation as the development platform of embedded system. In order to realize the function of broadcasting TV and browsing BML information. First of all, we recompile the system development kit, then upgrade the system by using USB or USB ICE Tool. After building up the system of the platform, we need to add BML browser SDK to the platform system by linking the underlying API. To complete the above steps we can achieve the ability to play digital TV channels and BML.
BML function which complete in the platform has improvement of the SDK transplant and system speed. So by BML browser development, we attempt to find out where the speed can be optimized. And the completion BML browser can save more development time in the transplant to other platforms.
