Patent ID: 8515195

Claim:
A remote editing system comprising: a main editing apparatus configured to transmit, to a remote editing apparatus via a network, first hierarchically encoded data that forms image, the first hierarchically encoded data belonging to a first predetermined hierarchical level, receive, from the remote editing apparatus, an additional request for a second hierarchically encoded data, the second hierarchically encoded data corresponding to the first hierarchically encoded data and belonging to a second predetermined hierarchical level, detect a difference between the first hierarchically encoded data already transmitted to the remote editing apparatus and the second hierarchically encoded data indicated by the additional request, and transmit, to the remote editing apparatus, the difference between the first and second hierarchically encoded data; and the remote editing apparatus configured to accept an editing operation using the first hierarchically encoded data transmitted by the main editing apparatus to edit content of the first hierarchically encoded data, generate the additional request for the second hierarchically encoded data, request the main editing apparatus to transmit the second hierarchically encoded data, generate edited image data using the second hierarchically encoded data transmitted by the main editing apparatus in compliance with the request, and transmit, to the main editing apparatus, time codes corresponding to edit points of a plurality of content of the edited image data.
