Abstract: An analog color video signal is prevented from being satisfactorily copied by inserting a phase-shifted color burst signal of predetermined duration into a predetermined location of the usual burst interval of that analog color video signal. The predetermined location may precede the normal color burst signal, or it may follow the normal color burst signal or it may be located in the middle of the burst interval.

In one embodiment, the system comprises a record circuit, an analog storage array, a playback circuit, and a control circuit that independently controls signal storage segments and duration capability. The record circuit receives an audio signal and generates a filtered signal, which is stored in the analog storage array. The playback circuit is coupled to the storage array for retrieving the stored signal for playback. The system further includes a mixer circuit which receives an auxiliary signal and mixes the auxiliary signal with the stored signal during playback. The control circuit also features a novel audio, visual, and input/output functionality.

Also included is a first submemory for storing the waveform data, and a second submemory for storing the system-sequence data. A sound signal generator generates sound signals based on the waveform data and the system-sequence data stored in submemories. A controller controls the entry of waveform data and system-sequence data of a selected music title, stored in the main memory, into the first and the second submemories, respectively. The controller also controls the sound signal generator based on the system-sequence data stored in the second submemory. A communication controller controls the entry of waveform data and system-sequence data, received from a host unit over a telecommunication line, into the main memory.
