Abstract
The invention is a method of detecting a TV off event happening on a mobile terminal equipment which is assumed to receive a broadcast service. A portable electronic device is connected to the mobile terminal equipment and, the mobile terminal equipment sends periodic commands to the portable electronic device. The mobile terminal equipment sends control messages to the portable electronic device. The control messages are related to the broadcast service. The method includes the steps of identifying a duration either according to receipt of two periodic commands of a first type or according to data contained in control messages, and identifying the TV off event if no control message has been received during that duration.
