Proposal of application format for hybrid digital TV developed for cost effective STBs

Contemporary devices for playing of video and audio signal from DVB bitstreams use complex hardware structure due to high requirements specified by standards like Hybrid Broadcast Broadband TV (HbbTV). The main focus of this paper is the proposal of a software that runs on set-top boxes (STBs). Instructions and attributes for STBs are contained in Extensible Markup Language (XML) and therefore XML scheme Definition (XSD) is used for defining and validating of XML file to operate on appropriate device without lagging. Cost effective devices in developing countries usually don't have hardware specifications that are high enough for complex video rendering and Graphic User Interface (GUI). Thus in this paper the proposition of XML and XSD is made as the suitable solution for low budget Set-top Boxes. Therefore, in this paper the definition of XML, XSD, the parsing and the validation of the code and the capabilities of such software for media interpretation are analyzed.
