Abstract
There is disclosed a system and method for transmission of data signals from a mobile device to a network. In an embodiment, the method comprises encoding video data at a first encoding rate into a plurality of video frames using a first encoding module; encoding video data at a second encoding rate into a plurality of video frames using a second encoding module; detecting a change in the availability of wireless bandwidth in the network; and switching a selector to retrieve frames from either the first encoding module or the second encoding module for transmission in dependence upon the available wireless bandwidth. The encoding rate of whichever one of the first encoding module and the second encoding module is currently not selected is successively increased or decreased, and a selector is switched to retrieve frames from either the first encoding module or the second encoding module.
