Methods and apparatus to verify and/or correct media lineup information
Methods and apparatus to verify and/or correct media lineup information are disclosed. Disclosed example apparatus include means for determining reference media, the means for determining reference media to identify a plurality of first signatures in a database that matches a plurality of second signatures included in media presentation data representative of media output by a media device in response to a mismatch between the media presentation data and reference data associated with first reference media corresponding to a first station, the plurality of second signatures generated from the media output by the media device; and determine second reference media corresponding to the plurality of first signatures; and means for storing the media presentation data.
1. An apparatus to build a channel lineup, the apparatus comprising:
means for executing a script from an audience measurement entity, the means for executing to:
access the script, the script including set top box commands to access a plurality of channels; and
execute the script to cause a device to transmit the set top box commands to a set top box to cause the set top box to access a first channel of the plurality of channels;
means for sensing a media signal associated with the first channel of the plurality of channels; and
means for transmitting media presentation data generate the media presentation including an association of the first channel of the plurality of channels with at least one of a watermark extracted from the media signal or a signature generated from the media signal, the means for transmitting to transmit the media presentation data to the audience measurement entity to correct a channel map based on the association.
2. The apparatus of claim 1 , wherein the plurality of channels include the first channel and a second channel, the media signal corresponds to a first media signal, and:
the means for executing is to execute a first command of the script to tune the set top box to the first channel;
the means for sensing is to receive the first media signal while the set top box is tuned to the first channel;
the means for executing is to execute a second command of the script to tune the set top box to the second channel; and
the means for sensing is to receive a second media signal while the set top box is tuned to the second channel.
3. The apparatus of claim 1 , further including means for extracting the watermark from the media signal, the watermark corresponding to the first channel, wherein: the means for sensing is to generate a timestamp; and the means for extracting is to generate the media presentation data based on the watermark, the timestamp, and the first channel.
4. The apparatus of claim 1 , further including means for generating the signature from the media signal, the signature corresponding to the first channel, wherein:
the means for sensing is to generate a timestamp; and
the means for generating is to generate the media presentation data based on the signature, the timestamp, and the first channel.
5. The apparatus of claim 1 , further including means for instructing the device to tune the set top box to respective ones of the plurality of channels.
6. The apparatus of claim 1 , wherein the device is a remote control device.
7. An apparatus to build a channel lineup, the apparatus comprising:
memory;
computer readable instructions; and
processor circuitry to execute the computer readable instruction to:
access a script from an audience measurement entity, the script including set top box commands to access a plurality of channels;
execute the script to cause a device to transmit the set top box commands to a set top box to cause the set top box to access a first channel of the plurality of channels;
sense a media signal associated with the first channel of the plurality of channels; and
transmit media presentation data to the audience measurement entity to correct a channel map based on an association of (a) the first channel of the plurality of channels and (b) at least one of a watermark extracted from the media signal or a signature generated from the media signal.
8. The apparatus of claim 7 , wherein the plurality of channels include the first channel and a second channel, the media signal corresponds to a first media signal, the processor circuitry to:
execute a first command of the script to tune the set top box to the first channel;
receive the first media signal while the set top box is tuned to the first channel;
execute a second command of the script to tune the set top box to the second channel; and
receive a second media signal while the set top box is tuned to the second channel.
9. The apparatus of claim 7 , wherein the processor circuitry is to:
extract the watermark from the media signal, the watermark corresponding to the first channel;
sense is to generate a timestamp; and
extract is to generate the media presentation data based on the watermark, the timestamp, and the first channel.
10. The apparatus of claim 7 , wherein the processor circuitry is to:
generate the signature from the media signal, the signature corresponding to the first channel;
generate a timestamp; and
generate the media presentation data based on the signature, the timestamp, and the first channel.
11. The apparatus of claim 7 , wherein the processor circuitry is to instruct the device to tune the set top box to respective ones of the plurality of channels.
12. The apparatus of claim 7 , wherein the device is a remote control device.
