METHOD OF ENCODING AND PLAYING BACK AUDIOVISUAL OR AUDIO DOCUMENTS AND DEVICE FOR IMPLEMENTING THE METHOD

摘要

THIS INVENTION CAN BE USED TO PLAY BACK AN AUDIOVISUAL OR AUDIO DOCUMENT RECEIVED IN A FIRST ENCODING FORMAT WITHIN A LOCAL AREA NETWORK. A FIRST DEVICE PLAYS BACK THE DOCUMENT IN THE RECEIVED FORMAT, THEN A USER DECIDES TO PLAY BACK THE DOCUMENT ON A DEVICE HAVING A SECOND ENCODING FORMAT.PLAYBACK IS FIRST STOPPED ON THE FIRST DEVICE AND THE DOCUMENT IS STORED . THE USER STARTS PLAYING BACK THE DOCUMENT ON THE SECOND DEVICE AT THE MOMENT AT WHICH PLAYBACK OF IT WAS STOPPED ON THE FIRST DEVICE. DEPENDING ON THE DECODING MEANS OF THE SECOND DEVICE, THE DOCUMENT IS TRANSCODED FROM THE FIRST ENCODING FORMAT TO THE SECOND ENCODING FORMAT . THE INVENTION ALSO RELATES TO A MANAGEMENT DEVICE FOR ISSUING STORAGE AND TRANSCODING REQUESTS SO THAT A DOCUMENT PLAYED BACK FROM A FIRST DEVICE CAN BE TRANSFERRED TO A SECOND DEVICE REGARDLESS OF THE CAPABILITIES FOR PLAYING BACK ENCODED DOCUMENTS ON THE FIRST AND SECOND DEVICES.
