Methods and systems are described for transmitting data to a mobile device. The data may include the time according to a reference clock of a separate display system which displays a video. The mobile device can use the time to obtain, typically from an internal database, information relating to the video, such as the sound-track of the video or retail information relating to products referenced in the video. The data is transmitted using advertising channels of a personal area network. The network may use the Bluetooth LE technology, with certain data broadcast on channel (37) and different data on channel (39). |
