1. A method to monitor streaming media, the method comprising: extracting, by executing an instruction with a processor, first metering data from first media to be provided to a media presentation device via a transport stream, the first metering data identifying at least one of the first media or a source of the first media; combining, by executing an instruction with the processor, the first metering data with second metering data obtained independently of the first media to form combined metering data, the combined metering data not being decodable by a meter associated with the media presentation device; transcoding the combined metering data, by executing an instruction with the processor, to form transcoded metering data having a format decodable by the meter associated with the media presentation device; encoding the transcoded metering data into a metadata channel associated with the transport stream; and streaming the transport stream and the metadata channel to the media presentation device.
