Title: (EN) Relay device, communication terminal, signal decoder, signal processing method, and signal processing program
(ZH) 中继装置以及信号处理方法
Abstract: front page image
(EN) The present invention provides a relay device, a communication terminal device, a signal decoder, a signal processing method, and a program all for realizing multi-party conversation system without increasing the processing computation cost compared with the conventional communication devices and method while preventing significant deterioration of decoded sound. A relay device comprises a receiving unit (11) for receiving coded information coded for each of layers by scalable encoding and transmitted from communication terminals participating in multi-party conversation, a reconstructing block (15) for creating control information used for combining the received coded information for each layer, and an integrating/transmitting block (16) for integrating the received coded information by scalably combining the information for each layer according to the created control information and transmitting the integrated coded information.
(ZH)

提供一种中继装置、通信终端装置、信号解码装置、信号处理方法以及程序,与以往的通信装置、通信方法等相比,不会增大处理中的计算成本,能够实现防止解码语音的严重恶化的多者通话系统。具有:接收单元(11),接收编码信息,该编码信息被从参加到多者通话的多个通信终端装置发送、且通过可扩展编码对多个分层的每一个进行编码而得到;重构处理单元(15),生成控制信息,该控制信息用于将接收单元(11)从各个通信终端装置接收到的编码信息以层为单位进行组合;以及统合发送单元(16),基于重构处理单元(15)生成的控制信息,将接收单元(11)从各个通信终端装置接收到的编码信息、可扩展地以层为单位进行组合并统合,同时,发送统合后的编码信息。
