Abstract
A test signal generator presents a test signal of pseudorandom data in a format which simulates the Grand Alliance Transmission Layer Signal for the 8- or 16- vestigial sideband (8/16-VSB) signal for Advanced Television (ATV) systems. An actual (non-test) Transmission Layer 8/16-VSB signal for ATV is in a particular format with properly formatted sync information and includes data which have been randomized, Reed-Solomon coded, interleaved, and trellis coded. The test signal generator provides data in the particular 8/16-VSB format which simulates the Grand Alliance transmission signal.
