Regardless of use of an encoding tool of the moving picture compression/encoding method in a moving picture decoding device at a recepti on side, it is possible to output from a transcoder an encoded bit stream which can be decoded and reproduced by a moving picture decoding device of the reception side. An encoding control section outputs encoding tool control information according to reception decoded information received from the moving picture decoding device of the reception side. A DCT device, a quantizer, and a variable-length encoder modify operations according to the encoding tool control information. The encoding control section outputs encoding start information according to the reception decoded information. A transcode start judgment section outputs a moving picture signal to the encoding section according to the encoding start information, thereby operating to start the transcode.
