发明名称 METHOD AND SYSTEM FOR INFORMATION TRANSMISSION
摘要 PROBLEM TO BE SOLVED: To make it possible to efficiently and flexibly transmit information such as pay-per-view audience information without depending upon an NTT public network. SOLUTION: An information acquisition device 5 transmits a wake-up trigger for transferring operation mode of an information accumulation device 3 from sleep mode of little power consumption to wake-up mode. On the other hand, when the wake up trigger is transmitted, the information accumulation device 3 has its own operation mode transferred from the sleep mode to the wake-up mode and, at the same time, has information accumulated in itself transmitted to the information acquisition device 5 after this transference of the operation mode.
