A method is described for transmitting entertainment or information consisting of both visual and audio data derived from a source to a plurality of users, without need for audible broadcasting of the audio data. The visual data is displayed on a visual display comprising one or more monitor display screens visible to the users. Separately, data derived from the audio data is transmitted in Bluetooth format via a scatternet comprising a plurality of personal portable handheld devices and a converter. The converter is coupled to receive the audio data and to convert it to Bluetooth data and configured to transmit the said Bluetooth data as a master in an initial piconet. Each personal portable handheld device, which may be a smartphone a tablet or a laptop, is associated with a respective one of the users, and is enabled both to serve as a slave in one piconet of the scatternet and as a master in another piconet of the scatternet, whereby the users may listen via their personal portable handheld devices to audio associated with the visual data displayed on the visual display. |
