Description
STA027 is a fully integrated SBC codec targeting
wireless audio transmission such as DVD rear
channels wireless speakers, USB dongle, PC
wireless speakers. The device is fully controllable
through a standard I²C bus.
Compression Engine
SBC
The SBC Subband Coding engine can be used
when high quality audio is required in wireless
applications (such as Bluetooth). SBC is an audio
coding system specially designed for Bluetooth
AV applications to obtain high quality audio at
medium bit rates, and having a low computational
complexity. SBC uses 4 or 8 subbands, adaptive
bit allocation algorithm, and simple adaptive block
PCM quantizers..
