Dynamic content stream delivery to a telecommunications terminal based on the excecution state of the terminal
A method and apparatus are disclosed for delivering a content stream to a terminal only when the terminal has a transducer (e.g., speaker, video display, etc.) that is (i) capable of outputting the content stream's media type, and (ii) there are no software applications running at the terminal that use the transducer. For example, if a terminal has both a speaker and a video display, and the terminal is running an application that sends output to the video display, an audio stream, but not a video stream, is delivered to the terminal. The illustrative embodiment is disclosed in the context of an interactive voice response system, but is applicable in a wide variety of other telecommunications systems and applications.
1 . A method comprising transmitting a signal of media type T to a telecommunications terminal only when:
(i) said telecommunications terminal has a transducer whose output is of said media type T, and
(ii) no applications are currently executing at said telecommunications terminal that use said transducer to generate an output signal.
2 . The method of claim 1 wherein the transmitting is during a call that involves said telecommunications terminal.
3 . The method of claim 2 wherein the transmitting is effected by an interactive voice response system that is involved in said call.
4 . A method comprising transmitting a signal of media type T to a telecommunications terminal only when:
(i) said telecommunications terminal has a transducer whose output is of said media type T, and
(ii) no applications are currently executing at said telecommunications terminal that use said transducer to generate a primary output signal.
5 . The method of claim 4 wherein the transmitting is during a call that involves said telecommunications terminal.
6 . The method of claim 4 wherein the transmitting is effected by an interactive voice response system that is involved in said call.
7 . A method comprising stopping the transmission of a signal of media type T to a telecommunications terminal during a call that involves said telecommunications terminal when an application is started at said telecommunications terminal that generates an output signal of said media type T.
8 . The method of claim 7 further comprising re-starting the transmission of said signal when said application is terminated.
9 . The method of claim 7 further comprising resuming the transmission of said signal when said application is terminated.
10 . The method of claim 7 wherein the stopping of the transmission of said signal is effected by an interactive voice response system that is involved in said call.
11 . A method comprising transmitting a first signal from a telecommunications terminal when an application that generates an output signal of media type T is started at said telecommunications terminal, wherein said first signal is for notifying at least one of:
(i) a network infrastructure element,
(ii) another telecommunications terminal, and
(iii) an interactive voice response system
that there is no available transducer at said telecommunications terminal for outputting said media type T.
12 . The method of claim 10 wherein said application is started during a call that involves said telecommunications terminal, and wherein the transmitting of said first signal occurs during said call.
13 . The method of claim 12 wherein said telecommunications terminal is receiving a second signal of said media type T when said application is started.
14 . The method of claim 13 wherein said first signal is also for stopping transmission of said second signal to said telecommunications terminal.
15 . A method comprising transmitting a first signal from a telecommunications terminal when an application that generates an output signal of media type T is terminated at said telecommunications terminal, wherein said first signal is for notifying at least one of:
(i) a network infrastructure element,
(ii) another telecommunications terminal, and
(iii) an interactive voice response system
that there is a newly-available transducer at said telecommunications terminal for outputting said media type T.
16 . The method of claim 15 wherein said application is terminated during a call that involves said telecommunications terminal, and wherein the transmitting of said first signal occurs during said call.
17 . The method of claim 16 wherein said first signal is also for re-starting transmission of a second signal of said media type T to said telecommunications terminal.
18 . The method of claim 17 further comprising receiving said second signal at said telecommunications terminal in response to the transmitting of said first signal.
19 . The method of claim 16 wherein said first signal is also for resuming transmission of a second signal of said media type T to said telecommunications terminal.
20 . The method of claim 19 further comprising receiving said second signal at said telecommunications terminal in response to the transmitting of said first signal.
