Synchronizing device and method that adjusts readout speed according to remaining quantity of data in memory while operating decoder on fixed frequency system clock

A synchronizing device comprising:

• a memory for storing therein data temporarily;
• a data reading-out means for reading data from said memory device;
• a data remaining quantity detection means for detecting remaining quantity of the data in said memory device;
• a decoder for receiving data from said data reading-out means;
• a fixed-frequency system clock for providing timing signals to the decoder;
• a number of data increasing/decreasing unit for receiving data from said decoder;
• and
• a data reading-out speed control means for causing remaining quantity of data in said memory device to be within a prescribed range by controlling data read-out speed of said data reading-out means such that it controls quantity of data outputted from said number of data increasing/decreasing unit based on detection of remaining quantity of data detected by said data remaining quantity detection means.

A synchronizing method comprising the steps of:

• storing data temporarily in a memory device;
• reading data of said memory device by data reading-out means, and passing the data to a decoder;
• operating the decoder according to a fixed-frequency system clock;
• detecting remaining quantity of data of in said memory device;
• and
• causing remaining quantity of data in said memory device to be within a prescribed range by controlling data reading-out speed of said data reading-out means based on detection of remaining quantity of data detected in said data remaining quantity detecting step.
