A device for provisioning, retrieving, and using data guide information transmitted in a digital broadcast signal is disclosed. A receiver receives the digital broadcast signal which includes digital television programming packets multiplexed with data packets and thereafter routes the received signal to a demodulator. The demodulator provides a demodulated signal to a detector which identifies data packets contained therein. A processor then determines the types of data in the data packets, as well as the respective channels on which the identified types of data are transmitted. The processor prepares a menu for a display screen enabling a user to select the channel of interest, and enables the user to be connected accordingly.

The device of claim 1 wherein the at least one data packet includes at least one link to a website, the operator interface module enables the at least one website to be selected, and wherein the processor enables the at least one website to be accessed. 8. The device of claim 1 wherein the data guide software code generates a data guide in menu format for display on the operator interface module. 9. The device of claim 8 wherein the operator interface module enables the operator to scroll through the menu before selecting a particular channel. 10. A method of providing a data guide summarizing types of data transmitted in a digital broadcast signal and the channels corresponding to the types of data comprising the steps of: receiving the digital broadcast signal containing digital programming packets and data packets;demodulating the digital broadcast signal;detecting the data packets;storing the data guide based on information contained in the data packets; and,displaying the data guide. 11. The method of claim 10 wherein the digital broadcast signal is transmitted in multiple channels, and wherein the receiving step is performed by scanning through the multiple channels. 12. The method of claim 10 further including the step of selecting one of the identified channels and gaining access to data transmitted on the selected channel. 13. The method of 10 performed by a central processing unit of a personal computer, wherein the displaying step is performed using a video monitor connected to the personal computer. 14. The method of claim 10 performed by a processor of a television, wherein the displaying step is performed using a video screen of the television. 15.
