<p>A method and system for transmitting data over a channel of a network. The method comprises: receiving data at a first node; encoding a first portion of the data at a first bit rate to generate a first encoded data stream; monitoring an indication of the capacity of the channel; transmitting to the second node a padded data stream via the channel, wherein padding bits are added to the first encoded data stream, in dependence on the indication of the capacity of the channel, to generate the padded data stream; determining if transmitting the padded data stream exceeds the capacity of the channel; and encoding a second portion of the data at a higher bit rate than the first bit rate, to generate a second encoded data stream for transmission over the channel, if it is determined that transmitting the padded data stream does not exceed the channel's capacity.</p> |
