TopfieldApplication Program
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,

web site address is http://www.windriver.com. Some vari-

http://www.i-topfield.com.
YourTAPs will be run under the following conditions:
Their extension name is tap. If they have any other ex-

Theyare in the Program Files folder. If they are in other

Forhow to transfer your program to the digital receiver, refer
to§ 9.3.
To run a TAPin the digital receiver, perform the following
steps:
