P800/P802 White Paper, January 2003 21 capacity. A ‘Load Module’ is constructed containing the languages for a given market. Therefore a number of load modules is specified for the P800 to cover all required markets. Language is selected at First Startup and Master Reset. Action when P800 is Initialised When the P800 is first started, the user is prompted to select a language as part of the initialisation procedure. The P800 is then restarted. If the user selected UK English, all of the alternative language files will be deleted, making 2.6MB extra space free on the C: drive in the above example. If the user selected any language other than UK English, then the selected language files are retained on the C: drive and the other language files are deleted. In this example, we assume that the user has selected Swedish and therefore the Danish, Finnish and Norwegian files are deleted during the restart procedure. In this case, approximately 1950KB is made free on the C: drive. The diagram below illustrates this for a generic P800, where the free user data area on the C: drive grows to 8.15MB.

P800/P802 White Paper, January 2003 22 Action at Master Reset Master Reset will delete everything on the C: drive except for Languages and (if selected by the user) user-installed applications. If a newly-initialised P800 goes through a Master Reset, the C: drive will look like this afterwards. If the user had included user-installed applications, then the P800 Demo, Chess and Solitaire would be deleted also. P800 C: Drive after Initialisation and Master Reset Data can be restored as follows: If the user has previously backed up the P800 using the PC Suite, then the C: drive can be restored to the exact condition it was in when the backup was made. Otherwise, data can be re-loaded from the following places: • Sony Ericsson Multimedia Content from the P800 Multimedia CD-ROM • Applications Chess, Solitaire and P800 Demo from the P800 Multimedia CD-ROM Since Multimedia content is easily transferable using Memory Stick, infrared or Bluetooth wireless technology beaming, it is simple to restore favourite content from someone else’s P800.
P800/P802 White Paper, January 2003 23 Folder View of Internal Storage This section explains in more detail how the data is organised on the C: drive. Note: The actual file and folder structure on the P800 is not exactly as shown in this document. When viewed from a PC using PC Suite for P800, the ‘C:’ drive is named ‘Phone Memory’, but only a subset of the folders is accessible from the PC. Language files are represented by the Language Files folder. The user has no access to this data. Multimedia is stored in a structure beneath the Media Files folder. There is a folder for each media type: audio, video and image. Documents (such as Microsoft Word files) are stored under the Document folder. An Other folder provides a place for files that do not fit into the other categories. Beneath each media type and documents, the material on the P800 is broken into Folders. For each named folder in the related P800 application, a folder is created beneath the applicable media type. For example if the user creates a ‘MyMP3’ folder in the Audio Player application, a ‘MyMP3’ subfolder is created beneath the audio folder. Unfiled folders are created in the initial folder structure and all material, including Sony Ericsson Multimedia Content, is placed in the unfiled folder by default. Generic P800 C: drive folder structure (simplified) In the above diagram, the folder structure is shown and the Sony Ericsson Multimedia Content (audio) files can be seen.
P800/P802 White Paper, January 2003 24 Phone and PIM Applications Phone The P800 is a full-featured mobile phone having full integration with the other functions of the device, including third party applications. The phone includes useful and fun features such as: • Personalised ringtones – conventional or polyphonic ringtones can be set in Contacts, giving audible indication of who is calling. Supported formats are AMR, Au, iMelody, MIDI, RMF (Beatnik) and WAV. • Picture Phone Book – if there is a picture of the person in Contacts, it will be displayed when making outgoing calls and when receiving the CLI with an incoming call. • Quick access back to the entry in Contacts, making it easy to try an alternative number or send an E-Mail if the contact is unavailable or busy. • Voice dialling – make a call by speaking the contact’s name. The contact’s name may be recorded when entering/editing the entry in Contacts. The call is made by pressing the OK button on the flip or the button on the headset. If a ‘magic word’ is recorded, contacts may be dialled by saying the magic word followed by the contact name. It is then not necessary to press any buttons. • Voice answer – an incoming call may be answered or sent busy signal, using the words recorded for ‘answer’ and ‘busy’. There is 40 seconds of storage space allocated for voice dialling and voice answer. This is enough for approximately 50 words (contact names plus ‘magic word’, ‘answer’ and ‘busy’) • Access to most other applications whilst talking on the phone. • Office handsfree (speakerphone) which is enabled when the flip is open, making it easy to access applications such as Calendar and Jotter whilst talking. • Flight mode enables the P800 to be used as a PDA in situations where radio transmitters may not be used. The GSM and Bluetooth transmitters (and receivers) are switched off. In FC mode, the phone is driven by the keypad, like a conventional mobile phone.

Contacts
The P800’s Contacts application holds the details of all the user’s contacts. It is available in FC
and FO modes and is fully integrated with the phone and other PIM applications. Each contact
can contain multiple phone numbers and E-Mail addresses, name and address details, personal
notes and a photograph of the contact or other image. This information will typically be
synchronised in to the P800 to begin with; contact data can also be added and edited on the
P800 itself. Local and remote synchronisation is possible to the SyncML standard.
Contact data can be beamed in or out using Infrared and Bluetooth. It can also be sent and
received using messaging. See the Object Exchange section for full details.
Contacts are displayed in a
list, which may be filtered by
folder such as business or
personal. Use the Jog Dial or
stylus to select the required
person.
Key communication details are
displayed first. One tap will
initiate a phone call, new
message or URL in the
browser. The Jog Dial can
also be used.
Photograph of Rosie stored in
Contacts.
A voice dial tag can be
recorded, enabling Rosie to be
called by saying her name.

P800/P802 White Paper, January 2003 29 Multimedia The P800 has extensive multimedia capability in many applications. This section explains the different standards supported and provides a summary of capability by application. Audio Formats The table below explains the various audio formats supported by the P800, together with indicative file sizes for 60 seconds of playback. Format Example File Size Description AAC Advanced Audio Coding. This is one of the audio compression formats defined within the MPEG-2 standard. Compared to MP3 it has more advanced features and is more efficient. AAC is commonly used as the audio component of an MPEG-4 video file or stream. The P800 Video Player can play AAC format audio which is encoded into an MPEG-4 file or stream. Such audio-only content is not common. AMR 94kB (12.2 kbps) Adaptive Multi Rate. AMR is a speech compression format that is highly optimised for the mobile environment, requiring as little as 4.75kbps bandwidth. AMR is used to convey voice recordings in MMS, when the P800 records at a rate of 12.2kbps. Sample rate is 8kHz and processing is done on 20ms frames. AU 1.35MB (22.05 kHz) Similar to WAV, this is an audio format commonly used in the Macintosh, unix and java worlds. It is not commonly used for content on mobile devices. iMel- ody 6kB A format commonly used for monophonic ringtones. MIDI 20kB MIDI means Musical Instrument Digital Interface. MIDI specifies a format which describes music in a binary format which may then be stored as a file. Unlike the other formats, MIDI is not a recording of music but a description which enables a local synthesizer to play the music from the instructions included in the MIDI file. MIDI is ideal for polyphonic ringtones. The P800 includes the Beatnik mini-BAE TM (Beatnik Audio Engine) providing support for General MIDI Level 1. MP3 960kB (128kbps) MPEG1 Layer 3 audio compression. MP3 is a very popular format for downloading songs from the internet. It is also increasingly available in personal and in-car audio equipment. MP3 files can be created with different size/quality compromises. RMF 72kB Rich Music FormatTM A file format developed by Beatnik combining the compact size of MIDI files with the high quality of sampled sound. WAV 1.35MB (22.05 kHz) This is an typically used for short ‘alert’ sounds. The size of files is determined by sample rate, bits-per-sample and mono/stereo.
P800/P802 White Paper, January 2003 30 Loudspeaker Characteristics General The P800’s built-in loudspeaker is most sensitive to middle and high frequencies; tones below 400Hz generate distortion instead of bass. Therefore, sampling frequency for WAV should not be reduced below 16kHz, otherwise the characteristic low frequency sampling ‘ringing’ will be very distinct compared to that of a more linear system. Recommended WAV file format for the loudspeaker is 22.050kHz sampling rate, 8-bit samples and 1-channel (mono). Recommended MP3 setting for playback over the loudspeaker is 64kbps mono. P800 Loudspeaker Ringtones The stimuli should be kept around 4 kHz in order to generate high SPL (~90dBSPL@40cm) ring tones (see frequency response in figure below). The speaker will accentuate with-in this band and alter the timbre of the ringer tones for frequencies around 2kHz. E.g. a square wave at 500Hz will not sound the same as a square wave at 2 kHz as is the case for a more linear system. Recommendation: Keep the bandwidth of stimuli as narrow as possible. For discrete signals (~80dBSPL@40cm) the band broadens to 2-5 kHz. These types of stimuli can be generated at a larger bandwidth as an analogue to the above reasoning. Stereo Headphone Characteristics The P800 is supplied with a pair of high quality stereo headphones. Recommended WAV file format for playback over the headphones is 44.1kHz sampling rate,16-bit samples and 2-channel (stereo). Files to this standard are very large – use WAV only for short bursts of sound. Recommended MP3 settings are 128kbps stereo.
