REALTIME DATA PROCESSING DEVICE AND METHOD

摘要

PURPOSE: A realtime data processing device and a method are provided to utilize an external memory as a portion of total FIFO buffer required to compensate jitter generated in transmission of realtime data to have a small internal FIFO buffer. CONSTITUTION: A receiving time setting unit(220) sets the receiving time when coded data from audio or video device are received to be decoded per predetermined units. An external memory interface(230) stores the data input from the audio or video device in an external memory through an external bus, and reads the stored data through the external bus. A FIFO buffer(242) temporarily stores the data read from the external memory for compensating jitter generated when approaching a transmission medium in order to transmit the data to the receive node. A packetizer(250) reads/packetizes the data from the FIFO buffer(242) and transmits the packetized data to the receive node through a link and physical layers.
