| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 99 === The objective of this thesis is to implement a tiled digital display system. This
system expects to have no platform-specific and hardware-specific constraints, and is
possible to operate well in all general-purposed PCs, laptops and handheld devices.
It will also support all media formats of the MPEG system. Users can use several
standalone machines to collaborate with each other to compose a digital display
system. In which every machine just has the ability to play MPEG format media
files, and it can range from handheld devices up to PCs. In the case of
implementation techniques, this system provides a master clock server to provide an
absolute time so that machines can synchronize to each other externally. Beside
external synchronization, it also deals with the popular lip sync problems. In the
case of software development cost, it is based on the free, cross platform and
open-source projects. It is not only low-cost but also cross platform. The
portability is also better.
