Content- and link-dependent coding adaptation for multimedia telephony

An apparatus for communication of multimedia data, the apparatus comprising:

• a first token buffer module that determines a first level of throughput associated with multimedia data communication from the apparatus to a network;
• a second token buffer module that determines a second level of throughput associated with multimedia data communication from the network to an access terminal based on feedback from the access terminal to the apparatus;
• a residual module that determines a budget associated with communication of a video unit of the multimedia data;
• and
• a coding module that codes the video unit of the multimedia data based on the budget and the first and second levels of throughput.
