Playback of a digital media is altered through identification of digital coding used to control playback. A promotion trailer not pre-recorded in the digital media is played (42, 44, 54) in addition to or in place of pre-recorded promotional trailers contained on the media (50, 54). For example, pre-recorded trailers pre-recorded on a DVD may be recognized (38), and instead of playing the pre-recorded trailer (50, 54), an updated trailer received from a broadcast is played (42, 44, 54). Promotion capabilities are enhanced since trailers, which are typically used to promote new movie releases, games related to movie releases and similar dated material, will have a short period of relevance. A new digital video player is used in the promotion method. The player includes the capability to receive, store, and play updatable trailers. |
