Abstract

Remote controller code format(s), transmitting/receiving apparatus thereof, and transmitting/receiving method(s) thereof are provided by which data can be transmitted/received using an intrinsic remote controller code format to prevent reciprocal compatibility with another remote controller of a different manufacturer. The remote controller code format(s) may include a header code, a custom code, a data code, an inverse data code, and an inverse custom code. One frame of the remote controller code format may be arranged in a sequence of the header code, the custom code, the data code, the inverse data code, the inverse custom code, and an end code. One frame of the remote controller code. format may be arranged in a sequence of the header code, the custom code, the inverse custom code, the data code, the inverse data code, a check sum code, and an end code. Also, one frame of the remote controller code format may be arranged in a sequence of the header code, the custom code, the inverse custom code, the data code, the inverse data code, and an end code. A high pulse may have the same length as a low pulse in the header code.
