Abstract: A communication terminal apparatus is separated into a housing that is capable of video/voice communications, and a housing that is capable of only voice communications. Since functions of the housing that is capable of only the voice communications are limited, the housing becomes small, can be stored in a pocket or the like, and can immediately go off-hook upon reception of an incoming call. Upon reception of a videophone communication request, the user goes off-hook using the housing that is capable of only the voice communications to immediately make voice communications with the partner terminal, and can switch the communication mode to the video/voice communications using the housing that is capable of the video/voice communications, as needed. Hence, even a communication terminal having a videophone function can comprise a video input/output function without impairing its portability and storability.

Abstract: A television camera 12 for picking up a subject and producing an video signal, a plurality of microphones 11L, 11R which are arranged so as to be separate from each other and which collect a vocal sound from the subject filmed by the television camera and output audio signals, an estimating circuit 13 for estimating the position of the sound source on the basis of the audio signals obtained from those microphones, and a coding circuit for encoding the video signal for a specific range of picture area centered the sound source position estimated by the estimating circuit with a larger amount of codes than the video signals for the other picture areas so that the picture area for the specific range may have a higher resolution than the other picture areas construct.

Abstract: According to this invention, a stereo voice transmission apparatus for coding and decoding voice signals input from a plurality of input units includes a discriminating means for discriminating a single utterance mode from a multiple simultaneous utterance mode, a first coding means for coding the voice signal when the discriminating means discriminates the single utterance mode, a first decoding means for decoding voice information coded by the first coding means, a plurality of second coding means, arranged in correspondence with the plurality of input units, for coding the voice signals when the discriminating means discriminates the multiple simultaneous utterance mode, and a plurality of second decoding means, arranged in correspondence with the plurality of second coding means, for decoding pieces of voice information respectively coded by the plurality of second coding means.

Abstract: Since a transmission route is set in accordance with the number of relaying broad band switching nodes present between two terminating nodes of a plurality of broad band switching nodes, a through-put characteristic, an affecting degree due to occurrence of a defect, the traffic of the entire network is distributed. In addition, when the system is started up, transmission routes with a minimum band width necessary for routing control have been set in all the broad band switching nodes. Whenever a call takes place, a transmission route is set and the band width is variably set by using an intelligent inference mechanism. Moreover, an intelligent distributed control for distributing such an intelligent inference mechanism in the broad band switching nodes is used. Thus, the load of processing a call can be decreased, while the reliability of the network and the improvement of the operating efficiency can be achieved.

Abstract: In a stereophonic voice transmission system for transmitting voice signals of a plurality of channels, a transmitting end encodes main data consisting of at least one channel voice signal among a plurality of voice signals of a plurality of channels and additional data required for reproducing the voice signals of the remaining channels from the main data, and transmits coded main data and the coded additional data to a receiving end. The receiving end decodes the coded main data, and encodes and combines the main data with the additional data to reproduce the voice signals of the remaining channels, thereby transmitting stereophonic voice signals along a transmission line of a low transmission rate, with high quality at low cost.
