Patent ID: 7839893

Claim:
A voice data transmitting and receiving system comprising: a transmitting terminal including: a first generation unit that generates voice data Real-time Communication Packets (RTPs) based on received data; a division unit that divides the voice data RTPs into a plurality of voice data RTPs in clause units; a second generation unit that combines the plurality of voice data RTPs in the clause units obtained by the division unit to generate a single piece of packet data; a third generation unit that converts the single piece of packet data generated by the second generation unit into file data; and wherein, according to a monitored communication status, the transmitting terminal transmits the data generated by the first generation unit through a transmission path when the communication status is normal, transmits the data generated by the second generation unit when the communication status is poor, and transmits the data generated by the third generation unit when the communication status is poor even further, and a receiving terminal that restores received data to reproduce voice data, wherein the receiving terminal restores the voice data RTPs when the voice data RTPs are transmitted through the transmitting path in the normal communication status, obtains packet data in the clause units by performing packet division on the received single piece of packet data and restores the plurality of voice data RTPs when the single piece of packet data is transmitted in the poor communication status, and restores the file data when the file data is transmitted in the further poor communication status.
