Advertising data is incorporated into predictively encoded, for example MPEG encoded, digital video representing a video feature such as a film or movie or television show or program or video game by re-encoding one or more sequences or groups of pictures of the video feature with reference to at least one frame of advertising data representing at least one advertisement so that the sequence of the video feature cannot be decoded without decoding the advertising data, thereby making it difficult, when the video feature is delivered to an end user by, for example, downloading or streaming over a network, for the end user to skip or delete the at least one advertisement from the video feature, without detrimentally affecting the video feature.
