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.
