Abstract:
A data decoder, comprising:a. a demultiplexer for inputting a multiplexed coded data including a first coded data and a second coded data, and a synchronous information for synchronizing the first coded data and the second coded data, and outputting the first coded data, the second coded data, and the synchronous information separately; b. a first buffer memory for inputting and storing the first coded data demultiplexed by the demultiplexer; c. a second buffer memory for inputting and storing the second coded data demultiplexed by the demultiplexer; d. a first decoder for inputting and decoding the first coded data stored in the first buffer memory, and outputting a decoded data as a first decoded data; e. a second decoder for inputting and decoding the second coded data stored in the second buffer memory, and outputting the decoded data as a second decoded data; and f. a timing controller for inputting the synchronous information demultiplexed by the demultiplexer, for obtaining a buffering time to store the first coded data in the first buffer memory as a first buffering time and a buffering time to store the second coded data in the second buffer memory as a second buffering time, and for controlling an output time of the first coded data stored in the first buffer memory to the first decoder based on the first buffering time and controlling an output time of the second coded data stored in the second buffer memory into the second decoder based on the second buffering time, so that the first decoded data by the first decoder and the second decoded data by the second decoder are output synchronously as indicated by the synchronous information.
