Modification signal generating method for use during broadcasting of infographic sequence, involves inserting modification information relative to infographic composition in signal, where signal modifies sequence to obtain modified sequence

摘要

The method involves inserting modification information (B1) relative to a modifiable infographic composition (C1) in a modification signal (S2), where the modification signal modifies the modifiable infographic sequence for obtaining a modified infographic sequence to be diffused by a playback apparatus (140). Characterization frame is inserted in the modification signal, where the frame includes a frame identification key and a control field that includes the modification information to define parameters of a part of the sequence. Independent claims are also included for the following: (1) a modification signal used in a method for broadcasting an infographic sequence by a playback apparatus (2) a storage unit comprising a modification signal readable by a computer (3) a computer program product comprising a program code instructions for executing a method for generating a modification signal (4) a method for generating a info graphic sequence used in a method for broadcasting an infographic sequence (5) an infographic sequence used in a method for broadcasting the infographic sequence (6) a storage medium comprising an infographic sequence (7) a computer program product comprising program code instructions for executing a method for generating a infographic sequence (8) a method for broadcasting an infographic sequence by a playback apparatus (9) a computer program product comprising program code instructions for executing a method for broadcasting an infographic sequence (10) a broadcasting device, comprising a info graphic sequence playback apparatus (11) an infographic sequence managing system, comprising a infographic sequence generating device.
