Abstract

A visual media viewing system comprises a server (102) and a viewing unit (106), connected via a network (104). The server (102) includes an image processor (108) and a data storage device (110) for storing visual media data. The viewing unit (106) includes a screen (112) for viewing at least a portion of a piece of visual media and a data storage device (120) for storing visual media data. Both of the respective data storage devices (110,120) are arranged to store data (124) corresponding to the same piece of visual media, locally. The image processor (108) is arranged to select a portion of the piece of visual media automatically and to generate a control data set (126) corresponding to the location of the portion of the visual media within the visual media data (124) and any operations performed thereupon. The server (102) is arranged to transmit the control data set (126) to the viewing unit (106) such that the screen (112) is arranged to display the portion of the piece of visual media that is stored locally. A method of viewing visual media over the network (104) is also disclosed.

12. A visual media viewing system according to claim 11 wherein the control data set is smaller than the portion of the visual pictorial media data.

13. A visual media viewing system according to claim 11 wherein the first network element has a display for displaying the pictorial image generated from the portion of the visual pictorial media data synchronously with its display upon the display of the second network element.

14. A visual media viewing system according to claim 11 further including a third network element connected to the network, including viewing means and a data store arranged to store said visual pictorial media locally, and the first network element is arranged to transmit the control data set to the third network element such that said viewing means is arranged to substantially synchronously display (a) the portion of the visual pictorial media that are stored locally, with (b) the display of the portion of the visual pictorial media upon the second network element.

15. A network element comprising

a data store for storing visual pictorial media data,

a selector for automatically selecting a portion of the stored visual pictorial media data as derived visual pictorial media data,

a first processor for processing said derived visual pictorial media data,

a data generator for generating a control data set related to the derived visual pictorial media data, and

a transmitter for transmitting the control data set across a network to a remote network element having a local copy of the visual pictorial media data stored thereupon,
