Abstract (en)
[origin: WO03043329A2] The invention concerns application-enhanced programmes. It further concerns related production and broadcast systems, in particular interactive digital television. It is now possible to manually activate an interactive application associated with a programme broadcast in a broadcasting channel. That solution is expensive and inaccurate and the control of the application is not managed by the production channel but by the broadcasting channel. The invention therefore provides the use of a broadcasting programme signal comprising primary data for reproducing the main passive content of the programme and watermarked in the primary data. Said secondary data comprise the controls for triggering at least an application such as, in particular, the control of one or more broadcasting parameters of said programme signal and/or of one or more applications, for example interactive or broadcasting applications, related to said programme signal.
