Since various applications is converged in digital televisions, playing game on DTV will be available in the immediate future. Game programming of DTV is more difficult than that of PC in a viewpoint of game development. Since TV use very simple remote controller as user interface, mapping type, choice type, and one-button type are used among mobile game user interfaces. In addition, we suggest to use text class, numeral class, bitmap class, and shape class of DTV OSD middleware which is proven software, instead of developing new DTV-oriented game engine. The proposed interfaces can be applied in various game situations and allow intuitive and fast operations. By using OSD middleware, game actions can be subdivided into state structures, OSD objects can be used as game objects, and events and actions of remote controller keys are easily defined.

In this paper, wd design the Program Specific Information (PSI) parser and its On-Screen Display (OSD) on the middleware of ALi M3330 MPEG-2 decoder processor to analyze DVB-T Transport Stream(TS) information. To test the functional operation of the designed parser, we implement the DVB-T test board including the RF-tuner using ALi M3330 MPEP-2 decoder processor and confirm the correct operation using the input TS stream generated by DVB-T stream generator. The developed PSI parser could be used for the test environment, various channel extension, and the development of DVB-T reception module.

This paper presents the development of DVB-T reception module including the RF-tuner. For the development of the reception module, we design the board using the ALi M3330 MPEG-2 decoder processor and implement its device driver. Simple On-Screen Display (OSD) applications are also designed on the middleware of ALi M3330 MPEG-2 decoder processor. To evaluate the performance of reception module, we test the decoding operations using the input TS stream generated by DVB-T stream generator and confirm the correctness of its functional operations.
