| 20120001832 | Updating an image - Method, terminal, network and computer program product for processing updates of an image for transmission from a first terminal to a second terminal for use in screen sharing between the first terminal and the second terminal wherein updates to the image displayed on a first display at the first terminal are also displayed on a second display at the second terminal. The image is divided into an array of contiguous sub-tiles, each sub-tile comprising more than one picture element of the image. It is determined that a plurality of sub-tiles of the image have changed at the first terminal and at least one of said changed sub-tiles and at least one contiguous sub-tile are selected to form a tile. The tile is encoded for transmission to the second terminal, said encoding determining sub-tile data identifying which sub-tiles are included in the tile such that the image can be updated at the second terminal in accordance with the changes to said changed sub-tiles, wherein the configuration of the tile is flexible such that the number of contiguous sub-tiles encoded in the tile can be varied. | 01-05-2012 |
| 20120005301 | Sharing an image - Method, server, network and computer program product for sharing an image between a first terminal and a second terminal. An original version of the image is received at the server from the first terminal. Tiles are then received at the server from the first terminal, each tile representing at least a section of the image and including a change made to the image at the first terminal. An image state is maintained at the server identifying which tiles are required for forming a latest version of the image. On determining that the latest version of the image is to be formed at the second terminal, tiles based on the image state for forming the latest version of the image are transmitted from the server to the second terminal. | 01-05-2012 |
| 20120275585 | Method of Transmitting Data in a Communication System - Processing of a signal received at a node in a network is described in which effects on the signal caused by applying an action to a first part of the signal are quantified based on characteristics of the first part of the signal and effects on the signal caused by not applying the action to the first part of the signal are quantified based on characteristics of a second, subsequent part of the signal. The action may then be selectively applied either to the first part of the signal or to the second part of the signal based upon the quantifications. In some embodiments, the action is applied to a portion of the signal for which the effects on at least one measure of the signal quality are less detrimental. | 11-01-2012 |
| 20120307677 | Transmitting Data in a Communication System - A signal to be transmitted from a terminal via a channel in a communication network is encoded by receiving the signal at the terminal; determining characteristics of the channel; encoding a first portion of the signal in accordance with a first encoding method to produce a first encoded signal portion; and encoding a second portion of the signal in accordance with a second encoding method to produce a second encoded signal portion. The first portion of the signal is encoded in accordance with the first encoding method depending on the determined characteristics of the channel. The first encoded signal portion and the second encoded signal portion are transmitted via the channel. | 12-06-2012 |
