摘要： PROBLEM TO BE SOLVED: To improve packet delay and break-off of telephone conversation in voice communication of mobile packet communication in which communication speeds of forward direction and backward direction are extremely different. SOLUTION: The voice communication system is composed including a mobile communication network comprising a plurality of mobile telephone terminals (MS1, MS2), an IP network 50 which is composed by connecting with the mobile communication network, and IP telephone sets 40 connected with the IP network. When VoIP communication is performed between any of the mobile telephone terminals and the IP telephone set 40, during a period data communication speed for backward direction is low in a case that data communication speed of backward direction is variable, mobile telephone terminals (MS1, MS2) which are a transmission side, thin out packets of the voice coded data, and transmit, and the IP telephone set 40 which is a receiving side, interpolates the thinned-out packets by packet information either front or rear, and reproduces.

SOLUTION: In a transmission side portable telephone terminal 11, voice data to be transmitted are sequentially inputted. Whether or not the inputted audio data is silent, is discriminated. The voice data discriminated that the shown voice is silent, is replaced with a group number. The group number that is replaced with the voice data that the shown voice is with a sound is radio transmitted. In a reception side portable telephone terminal 11, a radio transmitted signal is received. The voice data of the received signal and the group number are distinguished. The voice data are regenerated. The silence of the group number is regenerated. Further, a processing based on the group number is performed.

摘要： PURPOSE:To increase the freedom of device design, by providing a pause period in which no digital transmission is made in each sample, in a digital interface format of series system between digital-audio devices. CONSTITUTION:Interfacing of digital signals is made by using a PCM signal between various digital audio devices. In this case, each output signal has the same sampling frequency, in which information is present from the head of each sample to the N-th bit and no meaning is given from the N+1th bit to the beginning of the next sample. Further, the period from the N+1th bit to the beginning of the next samples is not always the same as the output signal of each device and each output signal has an uniform repetitive period in sample unit.

摘要： PURPOSE:To prevent the transmitting efficiency of a no-sound information from being deteriorated even if a no-sound block does not take place for a long time, by inserting forcedly the no-sound information to a prescribed sound block when sound blocks are consecutive for a prescribed or over. CONSTITUTION:A sound continuing time detecting circuit 5 outputs a no-sound information inserting request (c) to an information mixing control circuit 6 when the presence of a sound of a sound/no-sound discriminating result (b) is consecutive for a prescribed time T or over. The circuit 6 generates a switching signal (e) with the discriminating result (b), the inserting request (c) and a no- sound information transmitting request (d) and supplies it to a clock control circuit 7 and an information mixing circuit 8. The circuit 7 generates a sound information transmitting clock (g) and a no-sound information transmitting clock (h) from a basic transmitting clock (i) with the switching signal (e) and outputs a block synchronizing signal. The information mixing circuit 8 mixes the sound information from a blocking circuit 4 and the no-sound information from a terminal 9 with the switching signal (e) for transmitting the result.
