Embodiment Construction

[0015]Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several figures, and more particularly to FIG. 1, a data guide system according to the present invention is generally depicted by reference numeral 10. The data guide system 10 includes a digital vestigial sideband (VSB) broadcast signal transmitter 11 (such as a digital television provider), and a datacasting receiver 12.

[0016]The datacasting receiver 12 includes a digital scanning receiver 13, a demodulator 14, a detector 16, a processor 18, a memory 20, and an operator interface module 21. The digital scanning receiver 13 is a tunable receiver which is able to scan through and be tuned to the RF channels within the bands allocated to the digital scanning receiver 13, including, for example, any of the RF channels in any of the bands allocated for digital television viewing. In operation, the digital scanning receiver 13 receives a digital VSB broadcast si...

Abstract

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.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to an apparatus that enables a user to receive and utilize data which is broadcast via a digital vestigial sideband (VSB) broadcast signal.BACKGROUND OF THE INVENTION AND PRIOR ART[0002]The ATSC digital broadcast standard for digital television allows for the transmission of 19 Mbits / sec in an RF channel having a 6 MHZ bandwidth. Although this allocated bandwidth is adequate for a single analog NTSC television channel, the ATSC bit rate permits the same channel to support the concurrent transmission of several standard definition television (SDTV) programs (i.e., programs displayable with a resolution comparable to that of the NTSC analog program). Alternatively, the allocated bandwidth at the ATSC bit rate permits a channel to support the transmission of a single high definition television (HDTV) program at a time. Moreover, the ATSC digital broadcast standard permits data to be transmitted in the channel along wit...
