  • the present invention generally relates to a method for combining a first and a second video sequence into a combined video sequence, as well as a module, an apparatus and a computer-readable medium thereof.
  • the TV commercial is broadcasted in connection to a popular event or show
  • the viewers may switch channel or leave the TV during the TV commercials.
  • the advertising companies try to create more attractive TV commercials by means of better music, movie stars participating, etc., as well as replacing their TV commercials more frequent.
  • the TV commercials are made more attractive and are replaced frequently, many viewers will switch channel or leave the TV apparatuses during the TV commercials, and hence the messages from the advertising companies will not reach the viewers.
  • an objective of the invention is to solve or at least reduce the problems discussed above.
  • an objective is to present a method for generating a TV commercial by combining a first video sequence, corresponding to a newly sent sequence, e.g. a highlight of an original video sequence, with a second video sequence, herein also referred to as TV commercial template, configured to be combined with the first video sequence.
  • a unique TV commercial including a highlight sequence such as a touch down in the Super Bowl, may be generated rapidly and broadcasted in the TV commercial break.
  • An advantage of this is that there is a connection between the broadcasted show and the TV commercial. Therefore, since highlights are included in the TV commercial, more viewers will stay tuned during the TV commercial break.
  • Another advantage is that the TV commercial will vary from time to time, which means that more viewers will stay tuned and see the TV commercials. Still an advantage is the use of templates. In order to generate a TV commercial including a highlight, the editing of such a TV commercial must be made rapidly. This is solved by providing video sequence combination.

L'invention concerne un procédé permettant de combiner rapidement une première séquence vidéo et une deuxième séquence vidéo en un séquence vidéo combinée, telle qu'une publicité télévisée comprenant une séquence phare choisie dans une présentation radiotélévisée. Pour commencer, un certain nombre de premières séquences vidéo est généré à partir d'une séquence vidéo originale, de type spectacle en direct, au moyen de signaux de balise. Ensuite, une première séquence vidéo générée est sélectionnée pour être combinée à un certain nombre de deuxièmes séquences vidéo, les deuxièmes séquences vidéo étant configurées pour être combinées auxdites premières séquences vidéo.
