XDS enhancement system
First Claim
1. A system for facilitating use of extended data service (XDS) data by a television user, comprising:
- a tuner adapted to receive a television signal, the television signal including a video signal and an XDS signal;
a video display for receiving the video signal from the tuner to produce a video image;
a data slicer coupled to the tuner adapted to extract the XDS signal from the television signal;
a data port coupled to the data slicer for providing an output of the XDS signal to a peripheral device; and
a computer coupled to the data port for monitoring information in the XDS signal, the computer comprising a display;
wherein the computer includes a connection to an on-line service and a processor for interpreting URL data in the XDS signal and without user intervention displaying on-line information in response to the URL data on a display independently of the video display and simultaneously with the video image produced from the video signal.

Abstract
A television system and method for facilitating use of closed caption text or other information that may be included in an extended data service (XDS) system. The system includes a tuner adapted to receive a television signal, the television signal including a video signal and an XDS signal, and a television display for displaying a video image corresponding to the video signal. A data slicer coupled to the tuner extracts the XDS signal from the television signal, and sends the XDS signal out a data port to a peripheral device, such as a text display. The text display may be used to display text information included in the XDS signal, such as closed caption and/or other information included in text fields of the XDS signal. Alternatively, a computer may be coupled to the data port to monitor information, such as URL data, in the XDS signal to access on-line information. The computer may also be used toe control the tuner and/or other components of the system in response to information included in the XDS signal.
