Television / Online / Audio
The "Television/Online/Audio" department oversees and coordinates projects as well as the completion of tasks in the field of television technology, radio technology and television sound.
Projects are planned either with the input of IRT's Associates or in cooperation with industry partners and thereafter carried out by specialised fields of Research and Development at IRT.
Television Technology
encompasses both picture recording (lighting, camera, television studio), storage and editing of picture contents (coding, archiving, remote contribution insert) and finally specific issues of picture reproduction. As well technical processing of additional information for video signals as development of infrastructure for multimedia-based services up to Triple Play belong to the responsibilities of this department.
Great significance is attached to the digitisation of video signals. Both advancing digitisation in television studios for years and technical support of broadcast organisations in introduction of interactive Digital Television are principal topics in this department. Furthermore we are concerned with aspects of utilisation of IP networks for radio services.
