A broadcast device is disclosed, comprising a first memory unit, a demultiplexer unit, first and second flip-flop units, and first and second playback units. The demultiplexer unit generates an audio bit stream, which comprises a plurality of data packages, according to a transport stream. The demultiplexer unit writes the data packages into the first memory unit with a writing pointer. The first flip-flop unit reads and stores the data packages from the first memory unit. The first playback unit reads the data packages from the first flip-flop unit and decompresses the data packages for generating a first digital playback signal. The second flip-flop unit reads and stores the data packages from the first memory unit. The second playback unit reads the data packages from the second flip-flop unit and samples the data packages to generate a second digital playback signal to an external receiver outside of the broadcast device.
