 The DVB Multimedia Home Platform (DVB-MHP) defines a Java-based platform for the development of consumer video system applications.In addition to providing abstractions for many DVB and MPEG-2 concepts, it provides interfaces for other features like network card control, application download, and layered graphics.DVB has standardised a number of return channels that work together with DVB(-S/T/C) to create bi-directional communication.
