A memory operates for storing an information signal containing a video signal in response to the address signal. The address signal is periodically updated. A compression processing circuit operates for reading out the information signal from the memory, and subjecting the readout information signal to a compressively encoding process. A head of every frame represented by the information signal is detected. A state of the address signal is stored which corresponds to the detected frame head. Detection is made as to whether or not the information signal becomes discontinuous. The updating of the address signal and also the operation of the compression processing circuit are suspended when it is detected that the information signal becomes discontinuous. Detection is made as to whether or not the information signal returns to a normally continuous state after the information signal becomes discontinuous.

    Abstract: During decoding and processing of program clock reference (PCR) values in MPEG-2 transport streams, a first initial difference value is obtained by calculating a difference between a first detected PCR value and a system time clock (STC) value generated when the first PCR value is detected. Depending on the update status of the PCR values, a second initial difference value is obtained by calculating a difference between a second detected PCR value and a STC value generated when the second PCR value is detected. Thereafter, a composite difference value is obtained by further calculating a difference between the first initial difference value and the second initial difference value. Subsequently, the first and second initial difference values, and the composite difference values are calculated for a predetermined number of detected PCR values so that the decoder clock signal is generated and maintained at approximately the same frequency as an encoder clock signal.

This converted analog sine wave is phase compared to an input analog sine wave supplied to an input terminal of the synchronization apparatus. The phase of the digital sine wave is synchronized with that of the input analog sine wave by controlling a read address signal of the memory storage based upon a detected phase error signal between the input analog sine wave and the converted analog sine wave.
