Gathering research data

An article of manufacture comprising instructions that, when executed, cause a processor to at least:

• generate message data by supplementing first information collected by a first monitoring device with second information collected by a second monitoring device, the first information and the second information collected from media presented by a monitored device;
• store an indication that the message data is valid when the message data represents a code encoded in the media;
• process the message data to determine a portion of the media that is encoded and a portion of the media that is unencoded;
• and
• store data in a database indicating the portion of the media that is encoded.

A method for processing research data gathered by monitoring devices, the method comprising:

• generating message data by supplementing first information collected by a first monitoring device with second information collected by a second monitoring device, the first information and the second information collected from media presented by a monitored device;
• when the message data represents a code encoded in the media, storing an indication that the message data is valid;
• processing the message data to determine a portion of the media that is encoded and a portion of the media that is unencoded;
• and
