first picture encoder receiving from a photographing device one of a still picture signal and a moving picture signal, and converting the input picture signal into an I picture corresponding to a moving picture format, second encoder receiving the audio data signal and converting the audio data signal into a signal corresponding to an audio format, picture generator generating fixed data of P or B data, corresponding to picture size, representing motion vectors of all blocks of one entire frame and representing a predictive code of a preceding frame, wherein for the still picture signal with the audio data signal, the motion vectors are 0 for an entire frame and a chronologically preceding picture is copied as the encoded picture, third encoder multiplexing signals from the first encoder, the second encoder and picture generator and supplying the multiplexed signal to an output, and a fourth encoder receiving from the photography device the still picture signal and converting the input picture signal to an encoded picture having a still picture format.

68. Encoding method for encoding a picture signal and an audio data signal from an audio input unit comprising the steps of:
-
receiving, by an encoder from a photographing device, one of a still picture signal with the audio data signal and a moving picture signal with the audio data signal, and converting the input picture signal into an I picture signal corresponding to a moving picture format, converting the still picture into an encoded picture having a still picture format, receiving the audio data signal and converting the audio data signal into a signal corresponding to an audio format, generating fixed data of P or B data, corresponding to picture size, representing motion vectors of all blocks of one entire frame and representing a predictive code of a preceding frame, wherein for the still picture signal with the audio data signal, the motion vectors are 0 for an entire frame and a chronologically preceding picture is copied as the encoded picture, and multiplexing converted picture signal, the converted audio data signal and the fixed data and supplying a multiplexed signal to an output device.
