Abstract
An entertainment service consists of program material which is encoded, supplied and stored in receivers for later retrieval at the convenience of a subscriber or user. A number of unique options are available and include a format for the presentation of audio/video commercials and other message materials without interfering with the delivery of the program materials within which the message materials are to be inserted. Message materials may be targeted at specific program subscriber groups and specific program categories. The entertainment materials are electronically supplied in a unique format of the program and message materials selectively interspersed with program break flags and message flags. The flags identify and provide preselected access to the materials previously determined by the subscriber's service. The program break flags indicate where message materials are to be inserted in the program material, and the message flags identify the specific message to be inserted as well as provide time related information. The subscriber may select program material at his or her convenience in non-real time from a menu corresponding to the subscribed services.
