White Paper V600
MIDI is a specification for a communications protocol principally used to control electronic musical instruments. MIDI is today a well known standard used by many musicians, composers and arrang- ers.
A MIDI signal or file does not contain any music. It contains binary data (information) of how a melody is played and when this data reaches a synthesizer, the synthesizer will translate the binary data to music, when connected to an amplifier with speakers so that the sound becomes audible.

Sound recorder
The sound recorder can record both voice memos and call conversations. Sound recorder saves recordings directly to memory. The size and length of recordings are limited by available storage space.
Sounds are recorded in AMR format and saved in Sounds. Recorded sounds can also be set as ring- tones.
Video clips
Moments can easily be shared with friends and family in other geographical sites by capturing the moment with the video recorder and then sending the video clip in an MMS message. The video recorder supports QCIF and SubQCIF.
In order to view video clips in the phone, the media player supports download and playback of MPEG- 4 and H.263 formats.
Video clips may be downloaded from the Internet or copied from a connected computer.
Files must be of types MP4 or 3GP, having video encoded in
Streaming support
The media player can be launched from hyperlinks in the WAP browser, SDP files in My Items or in messages through hyperlinks. Content is streamed using RTSP (Real Time Streaming Protocol) session control.
DRM
Digital Rights Management, DRM, is a technology that enables secure distribution, promotion, and sale of digital media. Examples of such content include images, wallpapers and screen savers with themes from films, music tones from musical art- ists, and branded games. In other words, content providers can control how users may use different types of content in devices, such as mobile phones, smartphones or PDAs. Content providers can also control the use of content in related serv- ices, such as MMS.
Sony Ericsson is actively focusing on technology standardization for the DRM concept, and supports the ongoing standardization work and activities of the OMA (Open Mobile Alliance). Sony Ericsson is fully committed to open standard solutions in the
mobile environment and is a principal driver of many open standard initiatives. This will ensure the interoperability of mobile terminals in the DRM area and also result in a strong, competitive DRM stand- ard.
How DRM works
The control of the content in digital media is executed by defining usage rights for the content. The usage rights give the content providers flexibility in the way they can publish and sell content. Rights can be defined so that a picture can be used by subscribers only, and rights can be defined so that a music tone can be played only a limited number
