<P>PROBLEM TO BE SOLVED: To provide a terminal, a network camera, a program, and a network system capable of utilizing a buffer effectively, even if there is much silent data and a packet is delayed. <P>SOLUTION: The terminal (computer apparatus 2) stores received audio data into a voice reception buffer 23a temporarily for voice output. The terminal comprises a speech processing means 25, a buffer control means 25a, and a reception buffer level determining means 25b. The reception buffer level determining means 25b determines that it is no data or silent when the received audio data in the voice reception buffer 23a is equal to or less than a predetermined peak value for a constant time continuously, and it determines that there is sound when the peak value is exceeded. The buffer control means 25a discards audio data determined as no data or silent, and fills a space between the remaining audio data to output to the speech processing means 25. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
