Ifyou are good at programming with C++ language, you can
make a program executable in the digital receiver. We call
this Topfield Application Program (TAP).In making a TAP,
itis recommended to use Diab compiler of Wind River, whose
web site address is http://www.windriver.com. Some vari-

Forhow to transfer your program to the digital receiver, refer
to§7.7.
To run a TAPin the digital receiver, perform the following
steps:
