Monitoring

a. Except as otherwise provided in this act, no signal of any upstream communications channel may be transmitted from a subscriber terminal for the purpose of monitoring individual household viewing patterns or practices except with the written authorization of the subscriber, contained in a document separate from any contract entered into by the subscriber and a cable television company for non-interactive cable television services. b. Except as otherwise provided by law, no person shall intercept a signal of an upstream communications channel transmitted from a subscriber terminal except the subscriber and the intended receiver of the signal. c. Written authorization shall not be required for a cable television company to conduct system-wide or individually addressed monitoring for the purposes of verifying system integrity, controlling return path transmission, or for any purpose for which personally identifiable information may be lawfully acquired pursuant to this act, except that, if not for such purpose, the monitoring shall not result in the creation of personally identifiable information other than the name and address of the subscriber.
