Apparatus and method for controlling buffer data level in receiver of data communication system, and apparatus and method for playing streaming data with adaptive clock synchronizer

摘要

buffer data amount adjusting apparatus and method in a receiver of a data communication system, and having an adaptive real-time clock synchronization relates to a data reproducing apparatus and method. ; buffer data amount adjustment device according to the present invention, a buffer, an adaptive rate determination unit determining a speed for the data stored in the buffer, and the adaptive rate decision according to the speed information provided by the unit and a data use that uses the data stored in the buffer. ; buffer data amount adjustment process according to the invention is determined by the rate to use for data stored in the buffer (a ) phase, and includes the step (b) using the data stored in the buffer according to a predetermined speed. ; real-time data reproducing method according to the invention for generating a clock comprising the steps of: (a), and in synchronization with the clock and a step (b) to play the recorded data in the buffer. ; real-time data reproducing apparatus according to the present invention is a buffer, an adaptive clock synchronization unit for generating a clock, and a clock reproducing portion for reproducing by decoding a real-time data stored in the buffer according to the clock generated by the adaptive synchronization. ; The real time data reproduction in the receiver adaptively operating environment according to the present invention It is possible.
