P800/P802 White Paper, January 2003 31 Image formats The table below explains the various image formats supported by the P800, together with indicative file sizes for a QVGA (320 x 240 pixel) image. Format Example File Size Description BMP 226kB Microsoft Windows Bitmap. A graphics format defined by Microsoft supporting 1, 4, 8 or 24 bit colour depth. No compression, so files can be very large. Used for icons and very small images. GIF 42kB Graphics Interchange Format. Highly compressed by limiting the colour palette to 16 or 256 colours. GIF is therefore good for icons and diagrams. When a Jotter sketch is send as an e-mail attachment, the GIF format is used. GIF (animated) 210kB (5 frames) A GIF file containing a number of images in a timed and repeating sequence. Some P800 applications display only the first image in the sequence. JPEG (.JPG) 13kB An image compression format managed by the Joint Photographic Experts Group. The format supports various degrees of compression, enabling different quality/file-size balances to be provided in one standard. JPG files support millions of colours and are therefore good for ‘real life’ photographs. MBM Multi Bitmap. This is a Symbian OS format for colour and greyscale bitmap images. PNG 166kB Portable Network Graphics. PNG compresses images with millions of colours no loss of detail, but has comparatively large file size. It is not commonly used. WBMP Wireless BitMap. Part of the WAP specifications, an image format optimised for small mobile devices. The P800 supports Black and White, 2-bit greyscale and 6-bit colour modes, according to ETSI 3GPP TS 23.040 Colour Screen Images having more than 4096 colours will be adjusted to display optimally within the capabilities of the P800 screen. Images larger than the display area will generally be scaled to fit the application window. The Image Viewer uses 192 x 144 pixels in full screen mode. Screen Specification Type: TFT Size, flip closed: 208 x 144 pixels, 40 x 28 mm Size, flip open: 208 x 320 pixels, 40 x 61 mm Pixel Size: 0.192 mm Pixel Density: 132 DPI (Dots Per Inch) Colour depth: 12-bit (4096 colours) Surface: Touch-sensitive, anti-reflective Illumination: Front-light

P800/P802 White Paper, January 2003 34 Data Flow Summary The diagram below shows a generalised view of the ways in which data can be imported, stored and exported. Data is stored in a generic multimedia structure for images, audio, documents, video and other. Therefore an image received as an e-mail attachment can be saved and used by any application capable of reading it. Beaming When an infrared or Bluetooth beamed object is received, the user is immediately notified via a dialog box on screen. The object can be viewed, saved or deleted. If no action is taken, the object is saved in the Beamed Inbox in Messages. The Send As command in many applications allows an item of data to be beamed from the P800. For more information see ‘Synchronisation and Data Transfer’ later in this document. Viewer The ‘Viewer’ boxes in the diagram are instances of P800 applications that show selected details of the object and provide an option to save the object and/or go back. Messages Objects embedded in or attached to messages can be viewed and saved via the Viewer mechanism described above. Wallpaper and ringtones can be set directly from MMS messages. The Send As command in many applications allows objects to be sent from the P800. It is also possible to add multimedia attachments whilst composing MMS and e-mail messages.
P800/P802 White Paper, January 2003 35 Application Behaviour This section highlights certain application capabilities that are useful to understand. Browser The Browser is able to read HTML based content from local storage. More importantly, a long tap on an object such as a picture will display a menu, from which it is possible to save the object to storage. This enables images to be collected and saved in internal or Memory Stick storage. Folder Mechanism Almost all applications use folders to allow the user to sort information into useful groups. This mechanism can also be used to move an object between the Internal Storage and the Memory Stick. The Media Format and Application Summary table above shows which built-in applications have this ability. A separate application menu function, where provided, enables an object to be copied between Internal Storage and Memory Stick. Control Panel Wallpaper. Screen Saver and default ringtone are set here. Refer to ‘Personalisation and Customisation’ later in this document for more information. Contacts In Contacts, the user can select a picture from the P800 storage and save a copy against a contact. A compatible audio file can be linked to a contact and played as a ringtone when that contact is identified as the calling party. PC Suite for P800 The PC Suite for P800 enables multimedia content to be freely copied and moved between the P800 storage and a connected PC. The Internal Storage and Memory Stick appear as separate drives when viewed from the PC. See ‘Synchronisation and Data Transfer’ later in this document for more information.
P800/P802 White Paper, January 2003 36 P800 Audio Player The P800 Audio Player is a multi-format digital audio player which enables the user to play a selection of favourite songs. Audio Player Specification Formats: MP3, WAV, AU, AMR, MIDI, RMF, iMelody Features: Playlists, Loop, Automatic pause Songs may be stored in the internal P800 user storage and on Memory Stick. The folder system enables the user to organise songs into groups and create simple playlists of MP3 songs. It also allows songs to be moved between internal and Memory Stick storage. Songs may be collected in numerous ways, including internet download, file transfer from the PC using SyncStation and, of course, Memory Stick. The Audio Player is intelligently aware of other applications on the P800: • Playback is paused when a telephone call is made or received • Playback is paused if the user starts another application which requires the audio channels to be dedicated to it. • Playback of MP3 files continues if the user switches to another FO application or closes the flip, providing music whilst using other applications such as PIM or Messages. The Audio Player is started from the Application Launcher and is accessed in Flip Open mode. Folder ‘All’ is selected. It contains the songs listed in the lower half of the screen. ‘My music 4’ is currently selected. Details are displayed at the top of the screen including type and duration. MP3 song information is read from ID3 tags in the file and includes artist, album, filename and copyright. ID3 1.x and 2.0 is supported. In list view audio files are presented in a list and may be played one by one. In playlist view songs can be played in a consecutive list one after the other. A Loop function enables the playlist to be repeated automatically, providing continuous music. By default Audio lists only MP3 files, since this is most convenient for using the application as a personal music player. Other audio material can be viewed by selecting Edit, Preferences and ticking the required file types. Select ‘Other’ to see RMF and iMelody files.
P800/P802 White Paper, January 2003 37 Imaging Built-In CommuniCam The P800 has a built-in camera capable of taking still pictures up to 640 x 480 pixel (VGA) resolution (307200 pixels) and 24 bit colour depth. 320 x 240 (QVGA) and 160 x 120 (QQVGA) pixel sizes are also selectable. The camera may be used in Flip Closed mode for fast point-and- shoot pictures using the screen as the viewfinder. The lens is recessed into the back of the P800. With the flip open, the viewfinder is supplemented with graphical controls and access to camera settings. The viewfinder is always 160 x 120 pixels, irrespective of the resolution at which the picture is taken. A dedicated hardware button provides fast access to the camera application. Images are stored in the P800’s filing system and are therefore available for other applications to use. The number of images that can be stored depends on the available file space, which is shared with other applications. In FO mode, the viewfinder will give an estimation of the number of images remaining, assuming that all of the free storage is available for the camera application and using the current settings for size and quality. Approximate JPEG file sizes are 50kbytes for VGA, 18kbytes for QVGA and 3kbytes for QQVGA. Images are placed into a user-definable folder on either internal or Memory Stick storage. They may be viewed and organised in the Pictures application, and are available for use by other P800 and third party applications. In Flip Closed mode, the camera is optimised for ‘point-and-shoot’ speed: • Dedicated CommuniCam button • Ready/Busy indicator • Delay Timer icon .The timer gives an audible 15 second ‘countdown’ to the shot. The first press on the CommuniCam button will switch on the viewfinder. Each further press on the button will then act as a shutter and take a picture. With the flip open, additional on-screen controls are: • Shutter • View all pictures (shortcut to Pictures) Settings are accessed via the CommuniCam menu and include: • Image size • High/Medium/Low quality (low uses least storage space) • Brightness and Contrast • Backlight mode (when there is light behind the subject in the viewfinder) • Flicker-free mode (for fluorescent lighting) • White Balance (automatic or one of 4 pre-set values) Pictures remaining is calculated based on the current settings plus available space on the selected storage location (internal or Memory Stick).
P800/P802 White Paper, January 2003 38 Pictures Pictures is the P800’s image viewer. It enables you to view and organise your photographs. including pictures taken by the built-in camera plus images loaded from elsewhere, such as received via E-Mail or stored on a Memory Stick. Pictures supports image types JPEG, BMP, GIF (including animated), MBM, PNG and WBMP. Thumbnail viewing – images may be ordered by name, date, size or type. Tap an image to see it full-screen. Alternatively, a textual list including name, size and date may be displayed. Shortcut button to the Camera. In full screen mode, the user can browse through the images and organise them: • Categorise into folders • Rename or delete • Send as E-Mail or MMS The viewing area is 192 x 144 pixels. Images may be viewed ‘actual size’, meaning that each pixel of the source image is presented on one pixel of the screen. A full size 640 x 480 image from the camera will require 3 taps on the horizontal scroll bar to scan across it. Using Images Pictures may be loaded up to the internet. Sony Style Imaging is an on-line album enabling you to share your pictures and video clips. www.sonystyle-imaging.com Pictures can be easily sent as a Multimedia Message. Simply select a picture, add a message and send just like an SMS or build a slide show with several images and your favourite sound clips. Pictures of your friends can be saved in Contacts. When a contact calls (or the user calls that contact), the picture is displayed with the details of the call. This is known as ‘Picture Phone Book’
P800/P802 White Paper, January 2003 39 Video Playback and Streaming The P800 Video Player plays video content that is locally stored or streamed. It can also play audio-only material which is encapsulated within an MPEG file or stream. MPEG-4 Standard MPEG-4 was developed in 1998 by the Motion Pictures Expert Group, and has been incorporated into the 3GPP specifications for mobile multimedia. The earlier standards, MPEG-1 and MPEG-2 are widely in use for multimedia CD-ROMS and digital broadcast television for example. MPEG-4 has new functionality enabling to support both small mobile terminals and larger fixed devices within one standard. It has been adopted by 3GPP. MPEG-4 has the following advantages: • Flexible range of bit-rates supported, from 9.6kbps to 6Mbps (compared to 1.5 to 12Mbps for MPEG-2) • High error resiliency • Variable frame rate, enabling optimisation based on the transmission path and the overall load on the server. Video Compression The video compression component of the standard is called MPEG-4 Visual and covers a range of bitrates and functionalities. Profiles are used to describe functionality packages. Simple Visual Profile provides efficient and error-resilient coding of video content, and is supported by the P800 Video Player. MPEG-4 Visual is also broken down into levels, describing such things as frame size, bitrate and buffer capacity. Level 0 is targeted at mobile devices and provides for a frame size up to 176 x 144 pixels at maximum rate of 15 frames per second. Audio Compression AAC (Advanced Audio Coding) 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. The 3GPP standard uses AMR for audio coding, though this is actually outside of the MPEG-4 standard. This is because AMR is highly optimised for the mobile environment, requiring as little as 4.75kbps bandwidth. File Format The file format defined by MPEG-4 has extension MP4. It is applicable for both streaming and local storage/playback. MP4 uses a structured yet flexible method to describe and encapsulate multimedia material. 3GPP PSS (Packet Switched Streaming) Standard What is streaming? Streaming is a method of making audio, video and other multimedia available in near real-time, over the Internet or corporate intranets. Streaming media to computers has been used during the last few years, and now, with GPRS, EDGE and UMTS, the technique is can be used with mobile phones.
P800/P802 White Paper, January 2003 40 The name ‘streaming’ refers to the technique it is based on. Previously it was necessary to download an entire file to the hard disk or mobile phone and then play it, whereas through streaming the user can begin to watch or hear the content of a requested file after only a short delay. The data in the file is broken into small packets that are sent in a continuous flow, a stream, to the end-user’s computer or mobile phone. It is then possible to begin viewing the file from the beginning as the rest of the packets are transferred to the end-user’s machine or mobile phone while playing. The short delay at the start is to enable a small amount of data to be buffered. The data buffer enables playback to continue uninterrupted despite variations in the rate of received data. Applications The applications which can be built on top of the streaming services, can be classified into on- demand and live information delivery applications. Examples of the first category are music and video, news-on-demand applications as well as on-demand instructions material. Delivery of radio and television programmes are examples of live information delivery applications. User scenarios • Streaming of music on demand • Streaming of news (video, audio) on demand • Streaming of movie trailers on demand • Streaming and download of video on demand • Live streaming of music/video (broadcast) Standards, architecture and protocol Sony Ericsson supports the architecture, protocols and codecs for the PSS (Packet Switched Streaming) within the 3GPP system, as well as supports all ongoing standardization activities within 3GPP. Sony Ericsson constantly works to follow standards and to ensure interoperability between business solutions, and also stands up to meet additional market requirements within this area. The relevant 3GPP specification is TS 26.233 “Transparent end-to-end packet switch streaming service (PSS).” The PSS includes media codecs for video, still images, bitmap graphics, text, audio, and speech. P800 Video Player The P800 Video Player is used in Flip Open mode. Locally Stored Clips Video clips may be downloaded from the internet or copied over from a connected PC. Video files are large compared to still images. The demonstration videos Sony Ericsson has shown on the P800 require approximately 1 Mbyte storage per minute. Video files may be stored on Memory Stick as well as internal storage. Files must be .3GP or .MP4 having video coded in MPEG-4 Simple Visual Profile and audio in AAC or AMR format.
