Abstract

In a method for transmitting and receiving an image for display by a thin client, a parameter of a formatted image signal is used either as an indicator as to whether or not the image signal should be displayed by the thin client (1 in fig. 1) receiving the signal, and/or as an indicator of the position in which the image signal is to be displayed as part of a composite display of multiple image signals by the thin client. The parameter may dictate that an image is not to be displayed when this represents no change over a preceding image signal, and this image signal may be reduced in size before sending by a web server (2 in fig. 1). Simulated moving images can therefore be generated with lower latency and bandwidth. The parameter may comprise height and width image properties.
