White Paper Z500a

Songs may be stored in the internal Z500a user memory. The folder system enables the user to organize songs into groups and create simple playlists of MP3 songs.

Songs may be collected in numerous ways, including Internet download and file transfer from a PC.

The Media player is intelligently aware of other applications in the phone:

•Playback is paused when a telephone call is made or received.

•Playback is paused if the user starts another applica- tion which requires the audio channels to be dedi- cated to it.

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.

SP-MIDI

SP-MIDI stands for Scalable Polyphony MIDI. SP-MIDI is based on the MIDI format and adapted for mobile phones and other portable products. The objective is to secure interoperability between products with different sound capabilities.

•Playback of MP3 files continues if the user switches to another application, providing music while using other applications such as the phonebook or calendar, or playing games.

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 a picture message. The video recorder supports QCIF at 10 frames per second.

Polyphonic ringtones

Background

The word “polyphony” means producing several tones at the same time. Almost all music that we listen to consists of polyphonic melodies.

Early Ericsson mobile phones supported a proprietary non-polyphonic format called eMelody. Due to the musical limitations of eMelody, and the popularity of creating, sending and downloading ring melodies, Ericsson and Sony Ericsson, together with other manufacturers, created the more advanced non- polyphonic sound format – iMelody.

MIDI – Musical Instrument Digital Interface – is a specification for a communications protocol principally used to control electronic musical instruments. The MIDI files are small, and perfect for mobile devices, which have limited storage capacity. MIDI is today a well known standard used by many musicians, composers, arrangers and so on.

The Media player supports download and playback of MPEG-4 and H.263 formats for viewing video clips in the phone.

Video clips may be downloaded from the Internet or copied from a connected PC. Video files are large compared to still images (roughly 1 MB per 1 second of video).

Files must be of types MP4 or 3GP, having video encoded in MPEG-4 Simple Visual Profile and audio in AAC or AMR format. Video may also be encoded in H.263.

Streaming Support

The Media player can be launched from hyperlinks in the Browser or in messages. Content is streamed using RTSP (Real Time Streaming Protocol) session control.
