PURPOSE:To realize a small PC electronic conference terminal at a low cost by connecting an animation and a voice CODEC to a computer bus through the use of general use PC and a network control part for an ISDN line. CONSTITUTION:In an animation CODEC part 300, a video signal from a camera 51 is AD-converted 32, compressed and encoded 30 and these are fetched to a memory 13 in CPU 10. In a same way, in the voice CODEC part 400, a voice signal from a microphone 52 is A/D converted 42, compressed and encoded 40 and queuing to the memory 13 is conducted in PC 100. PC 100 transmits the animation and voice information of the memory 13 to the network control part 200. PC 100 separates AV multiplexed information from the control part 200 into voice, the animation, data and a bit assigning signal. Then, PC 100 respectively transmits voice information and animation information to the voice CODEC part 400 and an animation CODEC part 300. The CODEC parts 300 and 400 respectively conduct display in a display part 50 and drive a speaker 53. |
