An information delivery system including a head end broadcasting a data stream of media objects, the head end being coupled to a broadcast television interface and at least one information service provider and including an encoder for encoding information in the media object is disclosed. The system may deliver and implement a programming guide delineating programming information available on the information delivery system in one or more media objects in the data stream in an encoded fashion by the encoder. A user terminal is coupled to the head-end and receives the media objects. The user terminal has an output and includes a decoder for the media objects. Also provided in one aspect is a user interface, at least partially stored in the user-terminal, which selects a user-defined subset of media objects for provision to the output of the user terminal. Further, an information navigation system for an information delivery system is provided. The navigation system functions with the electronic program guide and includes a user interface having a plurality of icon representations of various functions of the system, and including a broadcast television interface. The navigation system also includes a smart service navigator which interacts with the user interface and the electronic program guide to provide an output to the user.

[ What is claimed is:] [1.] An information delivery system for delivery of audio, video, and user data through a communication medium from a head end to a user end, the user end including a display device, the communication medium having a plurality of transmission channels, said channels carrying a variety of broadcast programming information on ones of said plurality of transmission channels, comprising:a server node having means for broadcasting a data stream on a subset of said transmission channels, the data stream comprising a plurality of compressed data objects, each data object comprising at least one media object, each media object comprising a still image, a motion video image, an audio clip, or text in encoded form, the data objects further including broadcast programming content information and instruction code, directing the placement of the data and media objects on the display device to provide a broadcast programming information program guide, the data stream being substantially repeated at regular intervals in multiplexed fashion over the communication medium;a client node coupled to the display device, the client node having means for receiving the data stream, for decompressing at least selected portions of the stream, and for producing a user-detectable output on the display device in response to the data stream.
