Abstract: A decoding device and its associated decoding method are disclosed. In one aspect, the decoding device can be used for processing a first packet unit and a consecutive second packet unit, and includes a bit stream feeder, a decoder, and a determining circuit. The bit stream feeder provides the first packet unit and the second packet unit, and determines a boundary of the first packet unit to transmit a first boundary informing signal. The decoder decodes the first packet unit and the second packet unit, and determines the boundary of the first packet unit to transmit a second boundary informing signal. The determining circuit generates a determination result signal according to the first boundary informing signal and the second boundary informing signal. The decoder and the bit stream feeder operates according to the determination result signal so that the second packet unit is successfully decoded when the first packet unit cannot be successfully decoded.
