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.

A system, and a method of operation thereof, for analyzing the performance of a tape recorder having a playback head is disclosed. The system allows for the recorded data of the tape recorder to be routed to a analog-to-digital converter whose output is delivered to a digital signal processor preferably having a routine to convert the digital data to an FFT data stream which, in turn, is routed to a microprocessor. The computer analyzes the FFT data and provides digital signals to external display devices that indicate the proper recording of the tape recorder, the need for the recorder's heads to be cleaned, the occurrence of excessive dropout data recording rate, or the need to manually or automatically adjust the bias and equalization levels of the tape recorder.

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.
