(EN) SYSTEM AND METHOD FOR SEARCHING VIDEO SIGNALS
(FR) SYSTÈME ET PROCÉDÉ DE RECHERCHE DE SIGNAUX VIDÉO
Abrégé
(EN)
There is provided a system and method for searching video signals for content. More specifically, in one embodiment, there is provided a method comprising receiving video programming containing text data and video data, wherein the text data is associated with the video data, extracting the text data from the video programming, determining time information for the extracted text data, and generating an index file containing the extracted text data and the time information for the extracted text data.
