What is G.726?
G.726 is an ITU telecommunications standardization (ITU-T) standard for voice compression and decompression that was introduced in 1990. G.726 is used in digital transmission systems to encode analog signals into digital signals. It is an adaptive differential pulse code modulation for the transmission of speech at rates of 16, 24, 32 and 40 Kbps.
G.726 has its roots in the public switched telephone network and is mainly used for international trunks to save bandwidth.
G.726 ersetzt G.721 and G.723, einschließlich Standards und neuer Standards für 16 Kbps Datenübertragungsrate. Es war der Standardcode, der in drahtlosen Telefonanlagen mit digitaler verbesserter schnurloser Telekommunikation verwendet wurde. Es wird auch in einigen Canon-Systemen verwendet. Die vier Bitraten in G.726 werden durch die Bitgröße der Abtastwerte, die jeweils 2, 3, 4 und 5 Bits enthalten, bezeichnet.
G.726 compresses data by converting between the linear A law used in Europe or the u law used in Japan and the pulse code modulation used in the United States.
