Video clip identification system unusable for commercial cutting |
摘要 |
<p>A tagged scene of a video stream transmitted from a first to second stations in television broadcasting system is collected while preventing the tags from being used for commercial cutting (i.e., indiscriminate tagged scene cutting). The first station generates for each scene a tag includes a category, a location for use in locating a beginning of the scene and a length. A second station obtains a desired category from the user. Detecting a tag in the video stream, if the category coincides with the desired category, the second station clips from the video stream a part of the length defined in the tag from a position located by using the location. Five solutions are disclosed: removing the length information from tag; inserting counterfeit tags: the first station encoding a part of tag and the second station decoding the encoded part; the first station encoding the category and sending a category-encoded category table the second station; and a syndrome of a combination of said category and a parameter is used as an encoded category. The parameter may be used as subcategory and/or super-category. <IMAGE></p> |
