Incremental process of interprocess communication of different layers for digital television programming environments wherein the method includes two-way communication via callback function (203), which is activated depending on the functionality of digital television first draws a set of basic data structures and mechanisms for the specified service, so that encapsulates the minimum set (401,402,500,501) data structures and mechanisms, and then withdraw an additional set (502) of data structures and mechanisms required to activate this functionality service. Repair of digital television, for example EPG, PVR and Teletext, and each of said service in the transport stream described with the frequency of 501, video PiD and audio PID (500). TV application (103) is a Java TV applications for example EPG - electronic programmable application interface consisting of functions: Channel list, channel settings, current and next events. DTV Java API ( Application Programming Interface digital TV ) (201) consists of a package class management functionalities TV applications packages where classes can be EPG packages, HbbTV packages, PVR packages, Teletext Packs class Android operating system. |
