1. A picture transmission method for encoding moving picture data and transmitting the encoded data, the method comprising the steps of:
- encoding, based on selected position information transmitted from each of a plurality of user devices, a part of said moving picture data of a higher resolution than a moving picture stream; and
transmitting said moving picture data to said plurality of devices while transmitting said moving picture data corresponding to the respective selected position information of said encoding step, to each of said plurality of devices,wherein the encoding step includes encoding the established partial picture regions for transmission at a higher resolution for a predetermined period of time, after which, encoding of the established partial picture regions at the higher resolution is halted after the selected position information has moved out of the partial picture region.

Abstract
A picture transmission method is disclosed which involves encoding moving picture data and transmitting the encoded data. The picture transmission method includes the steps of encoding firstly the moving picture data into a moving picture stream for transmission at a predetermined data transfer rate, and encoding secondly, based on position information acquired from a transmission destination, a part of the moving picture data which constitutes a partial picture region for transmission at a higher resolution than the first encoding step.

5. A picture transmission apparatus for encoding moving picture data and transmitting the encoded data, the apparatus comprising:
-
an encoding means which, based on selected position information transmitted from each of a plurality of user devices, encodes a part of said moving picture data of a higher resolution than a moving picture stream, wherein said moving picture data is transmitted commonly to said plurality of devices while transmitting said moving picture data corresponding to the respective selected position information to each of said plurality of devices, and wherein the encoding means includes encoding the established partial picture regions for transmission at a higher resolution for a predetermined period of time, after which, encoding of the established partial picture regions at the higher resolution is halted after the selected position information has moved out of the partial picture region. - View Dependent Claims (6, 7, 8)

9. A picture transmission apparatus for encoding moving picture data and transmitting the encoded data, the apparatus comprising:
-
an encoding device which, based on selected position information transmitted from each of a plurality of user devices, encodes a part of said moving picture data of a higher resolution than a moving picture stream, wherein the moving picture data is transmitted commonly to said plurality of devices while transmitting said moving picture data corresponding to the respective encoded selected position information to each of the plurality of devices, and wherein the encoding device is configured to encode the established partial picture regions for transmission at a higher resolution for a predetermined period of time, after which, encoding of the established partial picture regions at the higher resolution is halted after the selected position information has moved out of the partial picture region. - View Dependent Claims (10, 11, 12)
