摘要： The present invention details a novel application of wireless networking and digital music technologies to achieve coordinated and synchronized music playback among peer listeners connected by wireless ad-hoc networks. Two or more listeners in local proximity allowed by short-range wireless transmission can participate and listen to the same song at the same time. Moreover, the present invention allows listeners in the transmission range to discover each other through profile matching. A high matching score may indicate similar preference or taste to a certain music style thereby easily locating mutual interests, which would not have been possible.

摘要： A method and an apparatus of loading a pre-load seed for a test code of a physical layer device (PHY). For a physical layer device including a scrambler and a Non-Return-to-Zero/Non-Return-to-Zero-Inverted (NRZ/NRZI) converter connected to the scrambler, where the NRZ/NRZI converter receives an NRZ signal outputted by the scrambler, and outputs an NRZI signal, the method includes the following steps. (a) Determine whether a plurality of starting bits of a frame are present. (b) Repeat from step (a) if the starting bits are not present. (c) Load the pre-load seed to the scrambler and transmitting the test code. (d) Set the NRZI signal in a high level when the NRZI signal is not in the high level. On the other hand, for a physical layer device having a descrambler, the method includes the steps of: (a) determining whether a plurality of starting bits of a frame are present; and (b) loading the pre-load seed to the descrambler to retrieve the test code. According to the invention, a frame starting-bits detector is used to determine the correct time to load the pre-load seed.
