Abstract: An apparatus consisting of a connecting cable with a built-in FM tuner and transmitter that connects a portable entertainment device with an external entertainment system over a number of preset frequencies, and which the user can quickly operate without needing to look at the apparatus in order to select a different FM frequency for playback operation if the need arises.

Abstract: A system for processing a PPS (precise positioning service) signal from a GPS (global positioning system) satellite to obtain PPS based positioning information therefrom. A first GPS receiver is adapted to process a PPS signal from a GPS satellite. The first GPS receiver is further adapted to output CVas (Crypto Variable Anti Spoofing) and SA correction information corresponding to the PPS signal. A second GPS receiver is adapted to receive the CVas and SA correction information from the first GPS receiver. The second GPS receiver is further adapted to process the PPS signal using the SA correction information received from the first GPS receiver and generate PPS based positioning information therefrom. The second GPS receiver does not include a KDP(key data processor). Accordingly, the second GPS receiver is not as tightly controlled as the first GPS receiver.
