A first user terminal, host terminal, method and program. The first terminal comprises: a transceiver for communicating with a plurality of other user terminals over a communication network; and communications processing apparatus, coupled to the transceiver, and arranged to participate in a call with a selected number of the other user terminals via the transceiver and communication network, the call including transmission of a voice signal from the first user terminal. The communications processing apparatus is operable in a mode whereby it temporarily discontinues transmission of the voice signal in response to detecting less than a predetermined level of activity on said voice signal, and the communications processing apparatus is further configured to selectively enable that mode in dependence on the selected number of other user terminals in the call.

Controlling multi-party communications

A method of controlling an audio output device at a user terminal connected to a communication network and executing a communication client is provided. The method comprises: establishing a connection between a user of the user terminal and a further user over the communication network; responsive to establishing the connection, analyzing the status of the audio output device with the communication client; in the case that the communication client determines that the audio output device is in a muted state, controlling the audio output device to deactivate the muted state such that audio information transmitted from the further user via the connection can be heard by the user of the user terminal.

Audio device control method and apparatus

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.
