<p>PROBLEM TO BE SOLVED: To provide a packet communication system that regulates a time required for transmission of a nonreal time packet so as to prevent a transmission delay of a real time packet from being increased. SOLUTION: The packet communication system is provided with a voice detection section 1 that detects input of a voice signal (real time information), a voice coding section 2 that applies high efficiency coding to a voice signal, a voice packet generating section 3 that assembles a voice signal subjected to high efficiency coding into packets, a voice packet storage buffer 4 that stores the generated packets, a data packet generating section 8 that assembles a data signal (nonreal time information) into packets, a data packet storage buffer 9 that stores the generated packets, a channel control section 5 that transmits the packets stored in the packet storage buffers 4, 9 to a communication network, and a data packet length revision section 7 that decides the length of the packet generated by the data packet generating section 8 on the basis of information of a coded frame period when the voice detection section 1 detects the voice signal and the voice coding section 2 conducts high efficiency coding.</p> |
