White Paper Z520 Product Overview The Z520 mobile phone features an attractive clamshell design and new communication experience that will allow the user to have more immediate fun with Instant Messaging and collaborative gaming. Also features a digital VGA camera, loop antenna, and Style-Up™ covers. Easy to use video communication provides a dedicated camera button for taking and sending a picture or video clip.
The camera also features a 4X zoom. Sony Ericsson’s constant ambition of making prod- ucts easier to use, has had a great outcome: QuickShare™. White Paper QuickShare is the fastest, easiest and smartest ever way to share images.
WAV, MP3 or MIDI (Polyphonic 40 voices or more). How the service works This service is owned by Sony Ericsson or hosted by Sony Ericsson for a network operator. The PlayNow™ or other premium content is maintained and managed, for example by Sony Music or Sony Pictures.
(audio, pictures, Music tones, video, entertainment features such as games etc.). Content-based services have great market poten- tial, and to encourage this, Sony Ericsson plans to support DRM in all future multimedia products. Sony Ericsson regards DRM as a key enabler for...
Design features Ergonomics and balance The phone strives for a perfect balance in your hand. Ergonomics links together with design. Display and keypad areas The 1.8 inch display area accommodates relatively large keys on the keypad area. The keys are aligned in a vertically grouped form. The display and key areas are designed with a sophisticated look.
The setup wizard includes: • setting the language • setting time and time format • setting date and date format • the possibility to import contacts from a SIM card • hints about the Back and C keys. PIM (Personal Information Management) The user can stay up to date with their everyday events by synchronizing the phone contacts, cal-...
– sports, movie, seasonal and other themes will be available on Sony Ericsson or operator sites. Other personalizable features are the start-up screen and the screen saver. Specific pictures and ringtones can also be set for each separate name in the phonebook.
Technologies in detail Imaging VGA camera VGA camera With the integrated VGA camera, the user can take pictures and video clips and store them in the phone memory. The user can send them as an attachment in an email or a picture message (MMS).
• VGA (640x480 pixels) • QVGA (320x240 pixels) • QQVGA (160x120 pixels) • Extended (1280x960 pixels) Video format Video clips can be recorded, played and sent using the following codec: Media player The media player supports different audio and video formats, streaming as well as download and playback.
Due to the musical limitations of eMelody, and the popu- larity of creating, sending and downloading ring melodies, Ericsson and Sony Ericsson, together with other manufacturers, created the more advanced but non-polyphonic sound format – iMel- ody.
Streaming Streaming media is a method of making audio, video clips and other multimedia available in real- time. The term streaming refers to the technique it is based on. Previously an entire file had to be down- loaded before it could be played, whereas the use of streaming means the end user can almost imme- diately begin to watch or listen to the content of a requested file.
Gaming Gaming is now seen as a standard feature in mobile phones, where Sony Ericsson promises to be a step ahead in this regard. This is not only due to faster download capability on the network. There are some other reasons why the actual gaming experience is better –...
Messaging My friends Sony Ericsson’s application - My friends - is an enhanced messaging facility that offers a user friendly and versatile way to quickly get in touch with contacts. The My friends application merges the Phonebook and messaging functionalities that we commonly find in phones.
You can manage the My friends list to quickly alter the list of contacts that you want displayed. You can sort the names, edit nicknames, block or delete a friend, or link a friend to the Contacts. Viewing the status of contacts in My friends You can view your contact’s status and decide how you want to communicate with him or her.
Text As with SMS and EMS (Enhanced Messaging Serv- ice), an MMS message can consist of normal text. The length of the text is unlimited. The main differ- ence between an EMS and MMS message is that in an MMS message, text can be accompanied not only by simple pixel images or melodies but by photographic images, graphics, audio clips and video clips.
the MMS network architecture, providing storage and operational support, enabling instant delivery of multimedia messages from terminal-to-terminal and terminal-to-e-mail, and supporting flexible addressing. The center’s MMS Proxy-Relay inter- acts with the application being run on the MMS- WAP/ Access Network MMSE Figure 1.
Connectivity GPRS The introduction of GPRS was a big step in the evolution of the GSM networks for enhancing the capabilities of data communication. Data traffic has increased (over both wired and wireless networks), with the growth in demand for Internet access and services paralleling that of mobile communications.

Bluetooth wireless technology facilitates instant connections, which are maintained even when the devices are not in the line of sight. Enhanced audio quality voice transmission is provided under adverse conditions, making it possible to use a headset connection to the phone at all times. Using Bluetooth wireless technology in Z520 True wireless connection...
connect to a Bluetooth device that can receive images and when the user then selects View, the image is transferred to the remote screen and dis- played. When the user then selects another image, that image is transferred to the remote screen and displayed.
An infrared link is a serial connection, which means that data bits are sent one after another in a long stream. The IrDA–SIR Data Link Standard is a pro- tocol that makes transmission of data faultless. The standard provides a high level of noise immunity, which means that the connection is not affected by fluorescent light and electromagnetic fields –...
SyncML – an open standard for synchronization SyncML background Leading the way in providing remote synchroniza- tion capability, Sony Ericsson realizes that interop- erability of remote synchronization is of utmost importance if mobile data usage is to become as widespread as generally predicted. That is why Ericsson, along with IBM, Lotus, Motorola, Matsus- hita, Nokia, Palm Inc., Psion and Starfish Software,...
Remote synchronization Remote synchronization takes place over the air using and is the ideal way to keep the phone up to date. Using GPRS, the phone can be continuously connected to the remote synchronization server. Firewall Sync Server PIM Application Third-party service providers offering synchronization services to corporate personal information manage- ment (PIM) applications, such as Microsoft®...
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.

Unless the content is encrypted, the user cannot copy DRM content to other devices since the Send to option is disabled for pictures, Music tones, etc. that are OMA DRM protected. Content providers may choose to protect some content, but leave some content unprotected.
When content is downloaded to the device, opera- tors generate revenues from the user via, for exam- ple, their billing system. Operators might in their turn be billed for rights by the content aggregator, content provider or directly by the content creator. Downloading server Content...
