摘要： A frame synchronization signal detection apparatus includes a synchronization signal detector, a main frame synchronization signal generator, a sub frame synchronization signal generator, and an output unit. The synchronization signal detector detects and outputs a synchronization signal from a digital data signal. The main frame synchronization signal generator detects and outputs a first valid synchronization signal from the synchronization signal, as an internal frame synchronization signal, and generates and outputs a first insertion synchronization signal, as the internal frame synchronization signal, if the first valid synchronization signal is not detected in a predetermined first time period. The sub frame synchronization signal generator detects and outputs a second valid synchronization signal from a synchronization signal. The output unit outputs a frame synchronization signal. The main frame synchronization signal generator stops generating the first insertion synchronization signal, and detects and outputs a first valid synchronization signal as an internal frame synchronization signal.

摘要： An optical disc reproducing apparatus including a viterbi detector for an optical disc in which digital data is stored includes an optical pick-up for reading digital data stored in the optical disc and for generating a high frequency signal, an analog-to-digital converter for sampling and quantizing the high frequency signal, and a viterbi detector for decoding a quantized signal output from the analog-to digital converter and reproducing an eight to fourteen modulation (EFM)/EFM+signal. The viterbi detector includes a branch metric calculator for receiving a signal constituted of n bits, for comparing the signal with previously set three variables, and for calculating a branch metric with respect to the input signal. A path metric update and storage unit receives the branch metric, adds the branch metric to values stored therein, compares the error content of all the possible paths with each other, and stores a metric with respect to the path having the smallest amount of errors. A path memory receives the output signal of the path metric update and storage unit and generates a viterbi decoded recovery signal. A stable eight to fourteen modulation (EFM)/EFM+signal is reproduced.
