Microsoft is testing TV signals to see if it can accurately broadcast data using TV satellites and cables - an experiment which could lead to TV-based Internet access.
Twelve US TV companies are helping the software giant with its tests to find out if reliable Web access can be achieved with TV signals. The broadcasts use a portion of the TV signal to carry data to Windows 98 PCs, which store them for access at a later time.
The next step is to include Web pages with live TV transmissions. Microsoft chief executive Bill Gates demonstrated a mock-up of that system at the Win HEC conference in San Francisco last April.
