    • A broadcast receiver includes an input unit, a receiving unit, a control unit, a main memory, a demultiplexer unit, and a decoding unit. When a user switches on or resets the main power by operating the input unit, an operation signal (main-power switching-on signal or reset signal) is supplied to the control unit via a bus. The control unit reads, via the bus, the bit-rate value of transport stream data stored in a program area in a main memory. The control unit computes the optimal size of the FIFO buffer area based on the read bit-rate value and confirms it. The control unit reserves, in the main memory, the FIFO buffer area based on a result of the computation.
    • 广播接收机包括输入单元,接收单元,控制单元,主存储器,解复用器单元和解码单元。 当用户通过操作输入单元来接通或复位主电源时,通过总线向控制单元提供操作信号(主电源接通信号或复位信号)。 控制单元经由总线读取存储在主存储器中的程序区域中的传输流数据的比特率值。 控制单元根据读取的比特率值计算FIFO缓冲区的最佳大小,并进行确认。 控制单元基于计算结果在主存储器中保留FIFO缓冲区。
