Abstract
A method and apparatus for perceptibly masking acquisition time in a digital broadcast system transmitting programs on multiple channels is incorporated in a receiver for the information signal transmission system. The apparatus and the method generate a reduced time response, independent of the acquisition time for complete video images, and provide an output for portraying a masking display from the receiver before the acquisition time has expired. A generator and the output display are easily employed with known video transmission systems by suing a microcontroller switch to select channels and retrieve audio or visual cues in response to an output response less than that necessary for communicating the entire program image.
