A set-top box receives media transport streams from a content provider server, decodes the media transport streams to a video program, and records the video program to a storage system. The video program includes program titles, program sections, and advertisements. The set-top box generates a plurality of unique identities of frames in one program title using types and media transport stream quantities of the frames. The set-top box signs other program titles in the video program by comparing types and media transport stream quantities of the frames with the generated unique identities during recording the video program. The set-top box can filter the advertisements according to the signed program titles. |
