Abstract
A system and method for performing video telephony (VT) is disclosed. In one example, there is provided an apparatus having a transceiver configured to receive VT data and information indicating a switch from a first display to a second display from a network. The apparatus also includes a decoder operatively coupled to the transceiver and configured to decode the VT data, a memory comprising a coded picture buffer (CPB) configured to store the decoded VT data, and a processor operatively coupled to the transceiver, the decoder, and the memory. The processor is configured to, in response to receiving the information indicating a switch from a first display to a second display, instruct the transceiver to transmit a request for an I-frame to the network.
