Abstract: Various embodiments process updates of an image transmitted between a first terminal and second terminal for screen sharing, wherein updates to the image at the first terminal are also displayed 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. When a plurality of sub-tiles of the image have changed at the first terminal, 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, and includes sub-tile data identifying which sub-tiles are included in the tile to enable updating the image at the second terminal in accordance with the changes to said changed sub-tiles. The configuration of the tile is flexible such that the number of contiguous sub-tiles encoded in the tile can be varied.

Abstract: A first terminal is coupled to a wide-area packet-based network and installed with first client application. One or more second terminals are coupled to the first terminal via a local wireless link, and each installed with an instance of a lightweight sub-client having reduced functionality relative to the first client. The first client establishes a call with a remote, third terminal over the network, based on a user credential identifying the first client. Each second terminal generates an audio or video stream, and each sub-client transmits the respective stream to the first client over the local wireless link for use in the call. The first client switches between a second state in which the call uses the streams from the sub-clients and a first state in which the call uses a stream generated by the first terminal without the streams from the sub-clients.

Abstract: A method of receiving at a terminal a first signal transmitted via a communication network, said method comprising the steps of; receiving at the terminal the first signal comprising a plurality of data elements; analysing characteristics of the first signal; receiving from a user of the terminal a second signal to be transmitted from the terminal; analysing characteristics of the second signal to detect audio activity in the second signal; and applying a delay between receiving at the terminal and outputting from the terminal at least one of said plurality of data elements; and adjusting the delay based on the analysed characteristics of the first signal and on the detection of audio activity in the second signal.

Abstract: Various embodiments process updates of an image transmitted between a first terminal and second terminal for screen sharing, wherein updates to the image at the first terminal are also displayed 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. When a plurality of sub-tiles of the image have changed at the first terminal, 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, and includes sub-tile data identifying which sub-tiles are included in the tile to enable updating the image at the second terminal in accordance with the changes to said changed sub-tiles. The configuration of the tile is flexible such that the number of contiguous sub-tiles encoded in the tile can be varied.
