EXTENDED MUSIC PLAYBACK
ST-Ericsson has invented innovative technologies specifically designed to reduce the battery power used by mobile phones when playing music. These technologies include:
-
The Playback Time Extender (PTETM), which typically doubles the audio playback time of a mobile phone platform by buffering audio data at high speed, enabling the actual playback to consume far less power. Originally developed for audio, the PTE™ technology is now also used for video.
- The Supply Modulated Audio Buffer (SMABTM), which ensures that no power is wasted when amplifying audio signals by adjusting the level of the power supply to the required volume.
