This sample demonstrates using the Microsoft Video Control in C++ to view ATSC digital television in a window. This is a simple ATL application that merely hosts the control and allows you to adjust the channel up or down.
When CPPVideoControl launches, it will look for an ATSC Network provider on your system. If a working tuner is found, CPPVideoControl builds the digital television filter graph, tunes to channel 46, and displays the broadcast signal. It may take several seconds to completely build the digital television filter graph, so please be patient.
