Abstract

PURPOSE:To confirm the information without waiting time by buffering a data on a transmission line to a temporary memory in a data broadcast receiver. CONSTITUTION:When a data transmission request comes from a CAPTAIN terminal 3 to a data broadcast receiver 2 via a transmission line 22, a reception circuit 6 of the data broadcast receiver 2 picks up a data in matching with a data transmission request from the transmission line 11 and receives it. Then the surrounding data relating to the picked-up data is collected to add an address number with an instruction of a buffering circuit 8 to a memory 7 in the data broadcast receiver 2. In this case, the data subject to transmission request is sent to the CAPTAIN terminal 3 with a transmission and reception circuit 9 while the data subject to transmission request is picked up from the transmission line 11 by the reception circuit 6. Then the succeeding data transmission request of the CAPTAIN terminal uses the buffering data from the memory 7 in common and the result is given to the CAPTAIN terminal. Thus, any irritating sense of a person desiring to observe the character graph information early is avoided.
