Methods and apparatus to verify and/or correct media lineup information
Methods and apparatus to verify and/or correct media lineup information are disclosed. An example method includes accessing, by executing an instruction with a processor, a script received from an audience measurement entity. The method further includes executing, with the processor, the script to tune a set top box to respective ones of a plurality of channels. The method further includes collecting, by executing an instruction with the processor, media identification data associated with the respective ones of the channels. The method further includes transmitting media presentation data to the audience measurement entity, the media presentation data mapping the media identification data to the respective ones of the channels.
1. An apparatus to build a channel lineup, the apparatus comprising:
a script interpreter to:
access a script received from an audience measurement entity, the script including commands to control a set top box to access a plurality of channels; and
execute the script to cause a device to transmit the commands to the set top box to instruct the set top box to access a first channel of the plurality of channels;
a sensor interface to sense a media signal associated with the first channel of the plurality of channels; and
a media presentation report generator to transmit media presentation data mapping the first channel of the plurality of channels to at least one of a watermark extracted from the media signal or a signature generated from the media signal, the media presentation report generator to transmit the media presentation data to the audience measurement entity to correct a channel map based on the mapping.
2. The apparatus of claim 1 , wherein the media signal includes at least one of data or metadata corresponding to at least one of audio signals, video signals, or Internet communications.
3. 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 script interpreter is to execute a first command of the script to tune the set top box to the first channel;
the sensor interface is to receive the first media signal while the set top box is tuned to the first channel;
the script interpreter is to execute a second command of the script to tune the set top box to the second channel; and
the sensor interface is to receive a second media signal while the set top box is tuned to the second channel.
4. The apparatus of claim 1 , further including a watermark extractor to extract the watermark from the media signal, the watermark corresponding to the first channel.
5. The apparatus of claim 4 , wherein:
the sensor interface is to generate a timestamp; and
the watermark extractor is to generate the media presentation data based on the watermark, the timestamp, and the first channel.
6. The apparatus of claim 1 , further including a signature generator to generate the signature from the media signal, the signature corresponding to the first channel.
7. The apparatus of claim 6 , wherein:
the sensor interface is to generate a timestamp; and
the signature generator is to generate the media presentation data based on the signature, the timestamp, and the first channel.
8. The apparatus of claim 1 , further including a transmitter interface to instruct the device to tune the set top box to respective ones of the plurality of channels.
9. The apparatus of claim 1 , further including a sensor to collect the media signal.
10. The apparatus of claim 1 , wherein the device is a remote control device.
11. A method to build a channel lineup, the method comprising:
accessing, by executing an instruction with a processor, a script received from an audience measurement entity, the script including commands to control a set top box to access a plurality of channels;
executing, by executing an instruction with the processor, the script to cause a device to transmit the commands to the set top box to instruct the set top box to access a first channel of the plurality of channels;
sensing, by executing an instruction with the processor, a media signal associated with the first channel of the plurality of channels; and
transmitting media presentation data to the audience measurement entity to correct a channel map based on the mapping, the media presentation data mapping the first channel of the plurality of channels to at least one of a watermark extracted from the media signal or a signature generated from the media signal.
12. The method of claim 11 , wherein the media signal includes at least one of data or metadata corresponding to at least one of audio signals, video signals, or Internet communications.
13. The method of claim 11 , wherein the plurality of channels include the first channel and a second channel, the media signal corresponds to a first media signal, and further including:
executing a first command of the script to tune the set top box to the first channel;
receiving the first media signal while the set top box is tuned to the first channel;
executing a second command of the script to tune the set top box to the second channel; and
receiving a second media signal while the set top box is tuned to the second channel.
14. The method of claim 11 , further including extracting the watermark from the media signal while the set top box is tuned to the first channel.
15. The method of claim 14 , further including:
generating a timestamp; and
generating the media presentation data based on the watermark, the timestamp, and the first channel.
16. The method of claim 11 , further including generating the signature from the media signal while the set top box is tuned to the first channel.
17. The method of claim 16 , further including:
generating a timestamp; and
generating the media presentation data based on the signature, the timestamp, and the first channel.
18. The method of claim 11 , wherein the device is a remote control device.
19. A non-transitory computer readable medium comprising instructions which, when executed, cause a processor to at least:
access a script received from an audience measurement entity, the script including commands to control a set top box to access a plurality of channels;
execute script to cause a device to transmit the commands to the set top box to instruct 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 the mapping, the media presentation data mapping the first channel of the plurality of channels to at least one of a watermark extracted from the media signal or a signature generated from the media signal.
20. The non-transitory computer readable medium of claim 19 , wherein the media signal includes at least one of data or metadata corresponding to at least one of audio signals, video signals, or Internet communications.
