Topfield

Established in South Korea in 1998, TOPFIELD Co., Ltd. is a consumer electronics manufacturer making broadcasting receivers, other video and audio related apparatus.

Their main business is making products such as set top boxes (STBs) and personal video recorders (PVRs) to be used with satellite television or digital television.

Topfield produces PVRs for standard- and high-definition television program recording.

[3] Various unofficial alternative versions of operating software with additional features and bug fixes have been made available, and the operation of Topfield PVRs can be substantially modified by installing third-party Topfield Application Programs (TAPs).
