In addition to WebTV there is an optional component called "Wave Top" that can be installed. WaveTop is a free service that offers high-value information over the web on the Public Broadcasting System's VBI signal. VBI is the Vertical Blanking Interval; this is a portion of the television signal used to send data along with the video and sound.
The information WaveTop offers will mainly consist of major newspapers and other consumer news services. Since the Public Broadcasting Service's signal reaches 99 percent of all domestic households over broadcast airwaves or via cable, this information will be readily available to you 24 hours a day, 7 days a week. Installation for WaveTop will require you to reboot at least twice, depending on hardware configuration.
To include WaveTop in your WebTV installation, do the following:
Make sure the WebTV for Windows option is selected, then choose details.
Click the check box next to "WaveTop Data Broadcasting"
Click OK to Return to the Add/Remove Programs screen, then click OK again to finalize the installation of WebTV for Windows and WaveTop.
