PROBLEM TO BE SOLVED: To enable correct editing by correcting the time lag of contents data requiring real time characteristics among a plurality of terminals. SOLUTION: A time stamp is added to a first contents data DrPD of a packet unit, and they are sequentially outputted. A second contents data GiPD of a packet unit to which the same time stamp as this time stamp are added, correspondent to the first contents data DrPD, are inputted from the outside. Time synchronization between the first contents data DrPD of a packet unit and the second contents data GiPD of a packet unit can be reliably assured with the time stamp by adjusting so that the first contents data DrPD and the second contents data GiPD are synchronized in terms of time on the basis of the time stamp. Thus, correct editing can be performed by correcting the time lag between the first and second contents data requiring real time characteristics. |
