摘要:
A monitoring device (1) comprising a basic set of audience research data retrieval units (7, 9) which are compatible with a broad range of AV appliances reproducing AV contents like TV sets (3). The data retrieval units are a audio watermark retrieval unit (9) and an audio signal sampling unit (7). For easy adaptation to particular AV installation, the monitoring device (1) is provided with internal and external connectors so that specialized modules can be integrated.
摘要:
A monitor (10) for capturing audience research data from a computer (2 - 8) having AV presentation capability is attached to the computer by a connector (12). The connector (12) allows to download software stored in the monitor (10). The software watches AV signals played back by the computer and furnishes data the AV signals to the monitor (12). Optionally, or instead of the software, the data detectable on the connector (10) may be analysed if they relate to AV signals played back.
