Abstract
Transmitting devices facilitate privacy protection of content broadcasted from the transmitting device to a receiving device without the need to modify the receiving device. A transmitting device may be adapted to acquire content, such as audio and/or video data, to be broadcasted by the transmitter for reception and use by a receiving device. A transmission range is selected to define a distance for broadcasting the content from the transmission device for reception and use by a receiving device. A frequency is also selected to be used for broadcasting the content. With the transmission range and frequency selected, the transmitting device may broadcast the content according to the selected transmission range and frequency.
