Claim Text:
1. A method for reducing interference in a passive optical network (PON) having radio frequency video overlay during an idle frame transmission state, the method comprising: detecting an idle frame transmission state in response to a signal indicating that packet data is not available: generating a first random number as a random length for an idle pattern and generating a second random number as random data of the idle pattern; generating frames having headers comprising the first random length while idle frame transmission state is detected, generating frames having headers with destination addresses not associated with any optical network terminal of the PON while the idle frame transmission state is detected; generating frames for transmission on the PON using the idle pattern in response to the detection of the idle frame transmission state; and generating frames for transmission on the PON having source data while the idle frame transmission state is not detected.
