Title:
ENCODING-DECODING SYSTEM, DECODING DEVICE, ENCODING DEVICE, AND ENCODING-DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/006837
Kind Code:
A1
Abstract:
An encoding-decoding system (300) comprises: a characteristic determination unit (301) for determining whether a sound signal is a vocal signal or an acoustic signal; an encoding unit (302) for encoding the sound signal into an encoded signal on the basis of the determination by the characteristic determination unit (301); a transmission unit (304) for transmitting the encoded signal; a receiving unit (307) for receiving the encoded signal; a decoding unit (305) for decoding the encoded signal; and a packet loss detection unit (308) for detecting the loss of the encoded signal data and reporting the detection result to the characteristic determination unit (301). When receiving the report on the loss of data, the characteristic determination unit (301) controls the encoding unit (302) such that the sound signal is encoded into an encoded signal comprising frames which can be independently decoded.
