An apparatus and a method for inserting and displaying one or more signals during 
processing and display delays encountered in digital STB-receivers, including those delays encountered during channel changes. Moreover, a means for increasing the channel change 
delay period, while maintaining subscriber satisfaction, and thereby freeing up bandwidth for other services, is provided. These signals can be advertisements, entertainment, or other messages. When a channel 
change request occurs on a digital set-top 
receiver, a local watchdog module detects the channel change event and causes to be generated a 
signal that is immediately displayed on the TV, while the MPEG-2 subsystem of the 
receiver acquires, stores, 
decodes and presents the new program to the television. Providing advertisements or entertainment during the 
delay period allows for increase in the 
delay period thus allowing for higher compression and increased availability of bandwidth.
