Game Programming of Digital Television Using OSD Middleware

Abstract

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 developmemt. 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.
