Abstract
In one aspect, a method of establishing a reduced setup time session through a gateway is provided which includes: receiving a first capability message transmitted from the first terminal to the gateway; receiving a second capability message transmitted from the second terminal to the gateway; transmitting first and second capability response messages from the terminal to the first and second terminals, respectively; receiving a media stream transmitted from the second terminal to the gateway; processing the media stream, including identifying a temporal feature in the media stream that enables a decoder to establish a decoder refresh point; receiving an acknowledgment message transmitted from the first terminal to the gateway; and, thereafter transmitting the processed media from the gateway to the first terminal.
