A Topfield Application Program (TAP) is a software application which extends the standard functionality of the Topfield products designed for digital TV. Examples of TAPs are electronic programme guides, digital photo viewers and MP3 players.
Anyone with the necessary computer programming skills may create a TAP to meet their needs. This is possible because Topfield have specified an open (or public) API which allows TAPs to be created using the C or C++ programming languages. They can be installed into most Topfield PVR models.
Some people have created TAPs and made them available for others to download and use, either free of charge or for a small fee. There are several internet forums dedicated to TAPs where information and support can be exchanged.
Famous quotes containing the words application and/or program:
“I conceive that the leading characteristic of the nineteenth century has been the rapid growth of the scientific spirit, the consequent application of scientific methods of investigation to all the problems with which the human mind is occupied, and the correlative rejection of traditional beliefs which have proved their incompetence to bear such investigation.”
—Thomas Henry Huxley (1825–95)
“In former years it was said that at three o’clock in the afternoon all sober persons were rounded up and herded off the grounds, as undesirable. The tradition of insobriety is still carefully preserved.”
—For the State of Vermont, U.S. public relief program (1935-1943)
