20110279658 | METHOD FOR SYNCHRONIZING REMOTE DEVICE - A method for synchronizing a function on a remote device with a function on a primary device includes selectively broadcasting, from a radio frequency (RF) transmitter of the primary device, data broadcast on channels at different times relative to a fixed period strobe signal of the primary device. Only the channels that have a noise level below a specified threshold level selectively broadcast the data and each of the channels have an associated fixed time frame offset relative to the fixed period strobe signal. Each of the channels is broadcast after their associated fixed time frame offset expires. An RF receiver of the remote device receives the data on one of the channels. The data on each of the channels is received at different times, depending on its associated fixed time frame offset, which results in the data on each received channel having an associated received time reference relative to a strobe signal of the remote device. The remote device strobe signal is synchronized to determine a received time reference and the fixed time frame offset. The remote device function is cyclically performed, which results in the remote device function being synchronized with the primary device function. The method may be used to synchronize a 3D video signal broadcast from a transmitter to sets of 3D glasses. | 11-17-2011 |
