Document Type and Number:
Japanese Patent JP2550690
Kind Code:
B2
Abstract:
PURPOSE:To attain the rendering of voice data with fidelity to original voice and the economical use of a data transmission path by transmitting all audio voice, transmitting only nonaudio voice following the audio voice, not transmitting the nonaudio voice after the second nonaudio voice in continuous nonaudio voice, and reproducing nonaudio data by the sequential number of the voice packet of received voice. CONSTITUTION:A voice packet transfer system consists of a voice packet switching part 10 as a transmission side, and a voice packet reverse switching part 20 as a reception side. Here, the transmission side separates the audio voice of multi-pulse encoded voice data from the nonaudio voice, and all the audio voice are transmitted, and only the voice packet representing the nonaudio voice immediately after changing from the audio voice to the nonaudio voice is transmitted when it is the nonaudio voice, and no voice packet corresponding to the voice of the nonaudio voice generated successively in the nonaudio voice is transmitted, and the reception side reproduces the nonaudio data by the sequential number of the voice packet of the received voice. In such a way, the voice data with fidelity to the original voice can be rendered, and also, the data transmission path can be used economically.
