Methods and apparatus to identify media application sessions
Methods and apparatus to identify media application sessions are disclosed. An example apparatus includes an audio interface to monitor an audio output of a media presentation device during a viewing session, a tone analyzer to identify one or more dual-tone multi-frequency (DTMF) tones presented by the audio output of the media presentation device, a session identification determiner to determine a session identification value associated with the viewing session based on the one or more identified DTMF tones, and a session report generator to associate a panelist identifier with the viewing session, and generate a session report based on the session identification value associated with the DTMF tones and the panelist identifier associated with the viewing session.
1 . An audience measurement meter configured to perform a set of operations, the set of operations comprising:
identifying multiple dual-tone multi-frequency (DTMF) tones audibly presented by a media presentation device within a section of audio during a media session, wherein a length of the section of audio is less than one second;
determining a panelist identifier of a panelist associated with the media session;
correlating the multiple DTMF tones with a session identification value using a tone identification database, wherein the session identification value is usable by a media provider to link demographics of the panelist with media presented by the media presentation device during the media session; and
reporting the session identification value and the panelist identifier to a server.
2 . The audience measurement meter of claim 1 , wherein the tone identification database maps various DMTF tone combinations to respective session identification values.
3 . The audience measurement meter of claim 1 , wherein the session identification value is usable by the media provider to identify the media presented by the media presentation device during the media session.
4 . The audience measurement meter of claim 1 , wherein the media session is a smart television application session.
5 . The audience measurement meter of claim 1 , wherein the set of operations further comprises:
generating a timestamp indicative of a presentation time of the section of audio; and
reporting the timestamp to the server.
6 . The audience measurement meter of claim 1 , wherein the media presentation device presents the section of audio prior to presenting the media.
7 . The audience measurement meter of claim 1 , wherein identifying the multiple DTMF tones comprises identifying 10 DTMF tones.
8 . A method comprising:
identifying, by an audience measurement meter, multiple dual-tone multi-frequency (DTMF) tones audibly presented by a media presentation device within a section of audio during a media session, wherein a length of the section of audio is less than one second;
determining, by the audience measurement meter, a panelist identifier of a panelist associated with the media session;
correlating, by the audience measurement meter, the multiple DTMF tones with a session identification value using a tone identification database, wherein the session identification value is usable by a media provider to link demographics of the panelist with media presented by the media presentation device during the media session; and
reporting, by the audience measurement meter, the session identification value and the panelist identifier to a server.
9 . The method of claim 8 , wherein the tone identification database maps various DMTF tone combinations to respective session identification values.
10 . The method of claim 8 , wherein the session identification value is usable by the media provider to identify the media presented by the media presentation device during the media session.
11 . The method of claim 8 , wherein the media session is a smart television application session.
12 . The method of claim 8 , further comprising:
generating a timestamp indicative of a presentation time of the section of audio; and
reporting the timestamp to the server.
13 . The method of claim 8 , wherein the media presentation device presents the section of audio prior to presenting the media.
14 . The method of claim 8 , wherein identifying the multiple DTMF tones comprises identifying 10 DTMF tones.
15 . A non-transitory computer-readable medium having stored therein instructions that, when executed by an audience measurement meter, cause the audience measurement meter to perform a set of operations comprising:
identifying multiple dual-tone multi-frequency (DTMF) tones audibly presented by a media presentation device within a section of audio during a media session, wherein a length of the section of audio is less than one second;
determining a panelist identifier of a panelist associated with the media session;
correlating the multiple DTMF tones with a session identification value using a tone identification database, wherein the session identification value is usable by a media provider to link demographics of the panelist with media presented by the media presentation device during the media session; and
reporting the session identification value and the panelist identifier to a server.
16 . The non-transitory computer-readable medium of claim 15 , wherein the tone identification database maps various DMTF tone combinations to respective session identification values.
17 . The non-transitory computer-readable medium of claim 15 , wherein the session identification value is usable by the media provider to identify the media presented by the media presentation device during the media session.
18 . The non-transitory computer-readable medium of claim 15 , wherein the media session is a smart television application session.
19 . The non-transitory computer-readable medium of claim 15 ,
wherein the set of operations further comprises:
generating a timestamp indicative of a presentation time of the section of audio; and
reporting the timestamp to the server.
20 . The non-transitory computer-readable medium of claim 15 , wherein the media presentation device presents the section of audio prior to presenting the media.
