Patent ID: 7690018

Claim:
A data processing apparatus for delivering coded multimedia data to a reception terminal connected to the apparatus via a network, comprising: first determination means for determining a screen size of a display screen of the reception terminal, based on device information of the reception terminal; second determination means for determining whether or not display positions and placement of respective objects constructing the multimedia data are to be transformed, based on the determined screen size; transformation means for transforming first object description data and first scene description data constructing the multimedia data, when said second determination means determines that the display positions and placement must be transformed, so as to change object(s) constructing the multimedia data without changing contents of the object(s) and to change a layout of the changed object(s) in the display screen of the reception terminal, to generate second object description data and second scene description data respectively, in accordance with the determined screen size; and selection means for selecting a coded bit stream of the object(s), described in the second object description data, from a predetermined storage device which holds a coded bit stream set for each object, wherein the coded bit stream sets are each coded by using a coding method suitable to a screen size of the display screen of the reception terminal, wherein the second object description data and the second scene description data are encoded, wherein the result of coding is multiplexed with the coded bit stream of the object(s) selected by said selection means, so that coded multimedia data is generated, and wherein the coded multimedia data is delivered to the reception terminal.
