The detection and recording of commercials ( 12 ) within content ( 10 ) to provide viewers with a choice to avoid watching commercials or view commercial content at a selected time. This invention proposes a way to allow the user to navigate through commercials ( 12 ) of interest without having to sit linearly through the commercials by recording the commercials and presenting the commercials to the user as a set of thumbnails, a menu or a Table of Contents mechanism. Content analysis algorithms can be used to choose the most representative key frame for the thumbnail. The invention can be used in conjunction with techniques to automatically delete commercials from recordings. The commercials are not watched by the viewer during initial viewing but are presented at user-selected times so the user can selectively view the commercials.
