Control broadcast programme signal, control write and read systems, related production and broadcasting channel
First Claim
1. A broadcasting program signal, comprising:
- primary data for the reproduction of the passive main content of the program, wherein it comprises secondary data watermarked in the primary data not altering the reproduction of the main content of the primary data, and secondary data comprise the commands for triggering at least one application related to the main content of the primary data.

Abstract
The invention relates to programs enhanced by applications. It relates, furthermore, to the associated production and broadcasting systems, in particular to interactive digital television. The activation of an interactive application associated with a broadcast program may be done manually in the broadcasting channel. This solution is expensive, lacks accuracy, and the control of the application is managed not by the production channel but the broadcasting channel. The invention therefore proposes to use a broadcasting program signal comprising primary data for the reproduction of the passive main content of the program and secondary data watermarked in the primary data. These secondary data comprise the commands for triggering at least one application such as, in particular, the controlling of one or more broadcasting parameters of said program signal and/or of one or more applications, for example interactive or broadcasting, related to said program signal.

9. A system for writing commands writing secondary data, allowing the triggering of at least one application, in a program signal comprising at least primary data for the reproduction of the passive main content of the program comprising:
-
a first input e1 receiving primary data for the reproduction of the passive main content of the program;
a watermarking device receiving the primary data of the first input e1 and secondary data, and generating a program signal comprising the primary data and the secondary data watermarked in the primary data, said watermarking not altering the reproduction of the main content of the primary data;
an output coupled to the output of the watermarking device;
a second input e2 receiving predetermined control criteria, a reproduction and editing device coupled to the first and second inputs e1 and e2, said device reproducing the main content of the primary data, which content is received on the first input e1, and editing on its output at least one secondary datum making it possible to control the triggering of at least one application related to the main content of the primary data, which application is reproduced according to the predetermined control criteria received on this second input e2. - View Dependent Claims (10, 11, 12)

13. A system for reading a command in a program signal comprising primary data for the reproduction of the passive main content of the program and at least one secondary datum watermarked in the primary data comprising:
-
a first input receiving the program signal, a watermark reading device, reading the secondary data watermarked in the primary data, the secondary data comprises commands for triggering at least one application related to the main content of the primary data, and in that said command reading system comprises an output receiving said application triggering commands. - View Dependent Claims (14, 15, 16, 23)

17. A program broadcasting channel comprising several devices, comprising:
-
a device for reading a program signal comprising primary data for the reproduction of the passive main content of the program and at least one secondary datum watermarked in the primary data, a program signal coder coupled to the output of said program signal reading device, and/or an interactive applications server, a device for broadcasting interactive applications coupled to said interactive applications server, a multiplexer coupled at least to the output of the program signal coder and/or to the interactive applications broadcasting device, a command reading system coupled to the output of said program signal reading device and/or to the output of said program signal coder, a coupling of said command reading system with at least any one of the devices of said broadcasting channel, the triggering commands generated by the command reading system controlling said device of said broadcasting channel, which device is coupled to said command reading system. - View Dependent Claims (18, 19, 20)
