A non-linear junction detector designed for counter surveillance measures achieves superior performance by transmitting a series of pulses and receiving harmonics of the transmitted pulse signals that are re-radiated by a non-linear junction such as would be found in an eavesdropping device containing a semiconductor. The transmit power of the series of pulses is varied and the amplitudes of the harmonics received at the different power levels are compared to determine the type of non-linear junction detected. The received harmonic signals are demodulated to create signals having a frequency in the audible range of human ears. The demodulated signals are broadcast so that an operator of the non-linear junction detector can audibly distinguish between the noise responses produced by the different types of non-linear junctions. The harmonic signals are analyzed to determine if the harmonic, signals correspond to signals produced by a known type of non-linear junction device such as a video camera or tape recorder. Data generated by the non-linear junction detector is displayed to an operator of the detector and may be stored for later analysis.

A system for transferring data from a television receiver to a display device and a shared data device includes a digital television receiver, a display device, at least one shared data device, and a communications channel coupled to the television receiver and the shared data devices. The television receiver receives, decodes, and processes a digitally encoded television signal (e.g., MPEG). This processed signal is provided to a display device (e.g., television monitor). In addition, an auxiliary data signal, sent with the digitally encoded television signal, is sent to at least one shared data device. Each of the shared data devices may be a printer, another television receiver, a digital video tape recorder, or a personal digital assistant (PDA). With a system as described herein, the auxiliary data may be an electronic program guide such that a viewer may print a program menu for subsequent review. Upon reviewing the printed program menu, the viewer may then select a channel for viewing or program a video tape recorder to record a selected channel. Alternatively, a viewer may transfer the electronic program guide to a PDA, review the program menu on the PDA, and subsequently program the television receiver, via the PDA, to select a channel for viewing or program a video tape recorder, via the PDA, to record a selected channel.

In a digital video tape recorder (VTR) which reproduces digital video and audio signals from a magnetic tape, a copy protect bit in the reproduced digital video signal is detected, and on the basis of the copy protect bit, a code is generated and inserted into the vertical blanking interval of the reproduced video signal. When a video signal (which may be in analog or digital form) having the code in the vertical blanking interval is received in a digital VTR, the code is detected and recording of the video signal and an associated audio signal is inhibited if the code indicates that the received video signal is copy protected.

A system provides messages from deceased relatives and friends, which messages are readily accessible. Before death a person records various messages for loved ones. The system stores these messages at a location and associates PIN numbers with each individual for whom there is a message. Either the intended recipient is given information about the message or leaving of a message by a symbol located in a conspicuous place, e.g., on the headstone of the deceased. The person then calls a 900 number or logs onto a specific website. In response to the correct answers to certain questions, the intended recipient is given their PIN. Using the PIN, the person can contact the system and received the recorded message at any time, e.g., by cell phone at the grave site. Alternatively, the grave site itself can be wired to provide the message, e.g., from a tape recorder over headphones or at special kiosks at the cemetery.

An audio or other program signal is modified to provide protection against copying on a magnetic tape recorder. The signal from a source (10) is amplified (16) and then subjected to Fourier analysis (11) to determine the signal amplitude in a plurality of subbands across the audible range. The subband containing the component of greatest magnitude is selected on an adaptive basis and applied to a stored psycho-sensorial model (12), which determines the maximum amplitude of interference which can be masked by the selected subband. An anti-copy signal is generated (14) by complex division of the desired interference by a stored representation of the response of a tape recorder (13).

An audio / visual surveillance system for use in mobile vehicles such as patrol cars includes two video cameras producing video signals and four audio sources producing audio signals. The signals are MPEG-2 compressed and streamed in real time with geographic and time data to a digital cartridge-type tape recorder located in the vehicle. A full patrol car shift is recorded on a single tape and, at the end of the shift, the tape is placed in a master sled bay. An MD5 hash authenticates the data for court use. Up to four videos can be synchronized frame-by-frame for simultaneous monitoring. An MPEG-1 stream is sent via wireless to headquarters in real time. One camera captures data external to the vehicle, while the other captures data internal to the vehicle. One audio source captures audio inside the vehicle and another captures dispatcher communications. The other two audio sources are carried by officers.

A helical scan tape recorder (30) comprises a rotatable scanner (84) and a transport system for transporting magnetic tape proximate the rotatable scanner in a manner so that information is recorded during a revolution of the scanner. A controller performs a pause routine (120) for pausing during a recording operation on tape. The pause routine, when executed, performs the steps of: determining a tape pause position reference value indicative of a pre-pause last recording position on the tape; recording an erase signal on the tape after the pre-pause last recording position; rewinding the tape; transporting the tape in a forward direction and obtaining a current tape position value; determining when the current tape position value reaches a predetermined value relative to the tape pause position reference value; and at beginning of a next revolution of the scanner, commencing recording of one or more post-pause stripes on the tape. In an example implementation, the predetermined value relative to the tape pause position reference value is a sum of the tape pause position reference value and an offset.

A process and facility supports recipient-specific customization of mass-duplicated tapes. Video from a master tape is passed through a VBI encoder whose output feeds two or more overlay units, each associated with a tape recorder. Recipient-specific watermarking instructions and address information for each tape are fed to the VBI encoder where they are encoded into the VBI of the video. Each overlay unit reads the VBI and decodes the address, and if relevant for that unit, applies the overlays to the video, which is recorded by its associated recording deck. Optionally, each tape and overlay unit includes a barcode that is scanned into a database where associations between tapes and the overlays are stored. Alternatively, high-density barcode labels that include the overlay instructions are printed and applied to tapes. The barcodes are scanned into the overlay units and applied following the receipt of a timecode or other trigger.
