Digital Video Broadcasting (DVB) protocol provides an alternative digital signage design, it does not use the Internet, while in DVB as the transmission mode, so that high-definition multimedia content can be steadily spread the display, so it can be removed to plug the control panel display side to significantly reduce system costs. Because DVB itself has broadcast features, implement synchronous multi-display digital signage easier and fit. This thesis is based on the DVB transmission technology, implementation, develop a functional and cost competitiveness of the digital signage system. In this thesis, using Ubuntu 12.04 with QT creator as a development platform for digital signage, computer software and provides many unique features, such as the integration of VLC, FFmpeg with gtk-recordmydesktop and other software features.
