Abstract

A method includes connecting a communications device to an Internet Multimedia Subsystem network. The method includes transmitting presence information indicating multimedia capabilities of the communications device and requesting multimedia content from a multimedia server to cause the multimedia server to transmit multimedia content. The method includes detecting connection of a peripheral device to the communications device and determining that the multimedia capabilities have increased due to the connection of the peripheral device. The method includes updating the presence information to indicate the increased multimedia capabilities and transmitting the updated presence information to cause the multimedia server to transmit the multimedia content adjusted for the increased multimedia capabilities indicated in the updated presence information. The method includes receiving the multimedia content adjusted for the increased multimedia capabilities and presenting at least some of the adjusted multimedia content on the peripheral device.
