A transcoder device includes means for receiving encoding information transmitted from a motion-picture encoding and transmitting device and decoding information transmitted from a motion-picture receiving and decoding device, referring to the encoding information and the decoding information to determine whether the syntax in a video packet transmitted from the motion-picture encoding and transmitting device is transcoded, and outputting transcoding control information, and means for transcoding an encoded bitstream that is input in the syntax level on the basis of the transcoding control information and transmitting the transcoded encoded bitstream to the motion-picture receiving and decoding device.
