CODING/DECODING DEVICE

PROBLEM TO BE SOLVED: To prevent occurrence of a skip and a repeat of a picture and abnormal sound in a created stream without installing a phase adjusting part for adjusting an error between a transmission side clock and a reception side clock when a coding stream inputted on a real time basis is transcoded. SOLUTION: A coding/decoding device is provided with a decoder, a video output memory, an audio output memory, a video input memory, an audio input memory and an encoder. When the coding stream of a first format is transcoded into the stream of a second format, a first data path and a second data path are switched to an on-state, video data decoded in the decoder is stored in the video input memory through the first data path and audio data decoded in the decoder is stored in the audio input memory through the second data path.
