ABSTRACT:
The present invention relates generally to a system and method of managing a Push To Talk (PTT) conversation while the recipient is watching television. PTT messages may be conveyed by an initiator to a recipient through the use of a telephone connected to a network. The network is also connected to either a set top box (STB) or a Digital Video Recorder (DVR). Within the network resides a presence state machine, which determines if a PTT conversation may be initiated. Upon initiation of a PTT conversation the presence state machine may pause the television by a command to the STB or DVR. If the television has been paused, upon termination of the PTT conversation, the presence state machine instructs the STB or DVR to resume television display.
