发明名称 Method and system for data communication
摘要 A method, a system and a device for data communication between a sender and a plurality of recipients are provided to be used for interactive multimedia systems such as interactive television game shows. First, the sender transmits over a data network a first message. The first message causes a response message returned by one of the plurality of recipients to be delayed for a random period of time. Then, the sender broadcasts a second message asking the plurality of recipients for a response message. After having received the second message, each recipient 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. 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.
