发明名称 SYSTEM AND METHOD FOR COMMUNICATING INFORMATION FROM A COMPUTERIZED DISTRIBUTOR TO PORTABLE COMPUTING DEVICES
摘要 <p>A method of transmitting information to a portable computing device (107) comprises, using a first communication protocol, transmitting a client (112) to the portable computing device (107). The client (112) configures the portable computing device to communicate with a distributor (103) using data transfer communication protocol. Using the data transfer communication protocol, the information is transmitted from the distributor (103) to the portable computing device (107). Transmitting the information includes generating, at the distributor (103), a polling signal, detecting, at the distributor (103), an acknowledgement signal (114, 19) generated, in response to the polling signal, by the portable computing device (107), and generating, in response to the acknowledgement signal, a broadcast signal (118) incorporating the information.</p>
