A method, a system 108 and a device 104 for data communication between a sender and a plurality of recipients 100 are provided to be used for interactive multimedia systems such as interactive television game shows. First, the sender transmits over a data network 110 a first message. The first message causes a response message returned by one of the plurality of recipients 100 to be delayed for a random period of time. Then, the sender broadcasts a second message asking the plurality of recipients 100 for a response message. After having received the second message, each recipient 100 initiates a response message. The response message is delayed for a random delay time. Thereafter, the response message is transmitted to the sender over the data network 110. Finally, the sender waits for a second period of time for response messages to arrive at the return address. A major advantage of the invention is a reduction of a peak load caused by the recipients' response messages. <IMAGE> |
