Sony Ericsson P1 manual Media formats

Play modes

The Media player has two different play modes: shuffle and loop.

•Shuffle plays a randomly selected file from the current playlist. Played files are de-selected and not repeated.

•Loop restarts the playlist when the last item in the list is reached.

DRM protection

In Sony Ericsson P1 the following types of DRM protection are used: FWL (Forward Lock), CD (Combined Delivery) and SD (Separate Delivery). All protection types can be applied on MP3, AAC and MPEG4 files. See “DRM” on page 47 for more information.

All protection types can be applied to all types of multimedia content such as audio, video, images and Java midlets.

Ringtones

Ringtones can be played in the Media player. Any file in a supported audio format can be used as a ringtone as long the operator has not disabled that format for ringtone use.

Ringtones can be downloaded using PlayNow™ or created using MusicDJ™.

Streaming

Media player content is streamed using RTSP (Real Time Streaming Protocol) session control, according to the 3GPP specification.

Audio support is AMR-NB, AAC, AAC+ and eAAC+, according to 3GPP.

3GPP specifies the following codecs:

•MPEG-4 Visual Simple Profile Level 0-3

•H.263 Profile 0 Level 10

Sony Ericsson P1 also supports:

•Real Audio

•Real Audio Video

Audio formats

Format	Description
AAC-LC	Advanced Audio Coding. AAC is the latest audio coding standard, defined in the
	MPEG-2 standard and used for high-quality audio compression. AAC provides higher
	quality than MP3 at the same bit rate, or for the same audio quality it uses a 30 per
	cent lower bit rate. It supports the coding of multichannel audio, with up to 48 main
	channels and 16 low-frequency channels. The AAC offers three different profiles to
	facilitate trade off between quality, memory and processing power requirements. They
	include: Main Profile (MP), Low Complexity (LC) and Scalable Sampling Rate (SSR).
	The Media player can play AAC-LC format audio which is encoded into an MPEG-4 file
	or stream. The Sound recorder uses the AAC-LC format for recording. AAC-LC
	includes High Efficiency AAC+.
AMR-NB	Adaptive Multi Rate. AMR-NB is a speech compression format that is highly optimized
	for the mobile environment, requiring as little as 4.75 Kbps bandwidth. AMR-NB is
	used to convey voice recordings in MMS, 3GPP video clips or streams. Sony Ericsson
	P1 records AMR using 12.2 Kbps with a sample rate of 8 kHz.
