Abstract: A system and method are disclosed for automatically inserting ITV-related data into a video signal based on the detection of certain events occurring during the show. According to the invention, certain components on the studio set are monitored for the occurence of corresponding events. Upon detecting one or more such events, a detection signal is output by a monitoring device (34), and a data encoder (38) then inserts corresponding ITV-related data into the video signal (40). In this manner, ITV-related data is automatically inserted into the TV program.

Abstract: A method and apparatus for delivering interactive television (ITV) data (Fig. 1) by using the same TV scan line that also carries closed caption data (12). The ITV data (14) is inserted into the scan line with CC data (12) by detecting a gap associated with a first CC data unit (12). If the gap is large enough to contain all of the group of ITV data units then electronically insert the entire group of ITV data units into the gap. If the gap is not large enough to contain the entire group of ITV data units, insert a subset of the entire group of the ITV data units into the gap and continue to the gaps associated with successive CC data units, inserting subsets of the ITV data into subsequent gaps until the entire ITV message has been inserted into the gaps between CC data units.

Abstract translation: 一种用于通过使用同样携带隐藏字幕数据（12）的TV扫描线来交付交互式电视（ITV）数据（图1）的方法和装置。 通过检测与第一CC数据单元（12）相关联的间隙，将ITV数据（14）插入到具有CC数据（12）的扫描线中。 如果差距足够大以容纳所有ITV数据单元组，则将整组ITV数据单元电子插入到差距中。 如果差距不足以容纳整个ITV数据单元组，则将整个ITV数据单元组的一部分插入到间隙中，并继续与连续的CC数据单元相关的差距，插入ITV数据的子集 进入后续的差距，直到整个ITV消息被插入到CC数据单元之间的间隙中。
