A method and apparatus for synchronizing a randomized video signal to a phase-locked sampling system. The phase-locked system is part of a scrambling apparatus capable of scrambling and subsequent descrambling of video signals recorded on videotape recorders which undesirably introduce time-base errors into the luminance/chrominance phase relationship. These time-base errors are removed without use of a time-base corrector by programmable delay line memory circuitry which introduces a programmable amount of delay into the video path. The delay line includes a programmable length FIFO memory module.

Um método e um instrumento para sincronizar um sinal video randomized a um sistema fase-phase-locked da amostragem. O sistema fase-phase-locked é peça de um instrumento scrambling capaz de descrambling scrambling e subseqüente dos sinais video gravados nos registradores da videocassette que introduzem indesejàvel erros do time-base no relacionamento da fase de luminance/chrominance. Estes erros do time-base são removidos sem o uso de um corrector do time-base por programável atrasam a linha circuitos da memória de que introduz uma quantidade programável atrasa no trajeto video. Atrasa a linha inclui um módulo programável da memória do FIFO do comprimento.
