  • the content acquisition interface 110 is adapted to enable the mobile terminal 105 to acquire a content data stream from one or more content providers 140, 141 and 142.
  • the content providers could include a dedicated device 140 adapted to transmit content data directly to the mobile 105, a personal computer 141 adapted to transfer content data files to the mobile phone, or an internet site 142 which can be accessed from the mobile phone via a telecommunication network to acquire content data, data may also be acquired via e-mail capability provided in the mobile terminal.
  • the content data stream may be displayed as it is acquired or stored on the mobile phone for later display.
  • the engine 120 is adapted to format the acquired content data stream according to one or more predetermined parameters.
  • the engine 120 can also control presentation and playing of the content on the display 130.
  • the parameters include parameters based on the limitations of the device display limitations for the mobile terminal 105, and user specified parameters.
  • parameters based on the device display capabilities can include: parameters based on screen resolution, colour display capability, image display capability, screen size, screen refresh rate, display buffer size and the like.
  • Examples of user specified parameters include: font size, font type, scroll rate, scrolling direction, colour mode etc.
  • the formatted data is then displayed using the display component 130, and the engine can be used control how the formatted content is displayed, for example based on user parameters for scrolling speed and font size.
  • the display component typically includes a screen.
  • the display component may also include features such audio output, tactile output such as vibration, or other visual outputs such as visual projection or lights.
  • Content data may be acquired in a format ready for display on the mobile terminal or as a data stream which is then formatted for display using the formatting component of the engine 120 of the mobile terminal.
  • the formatting component of the engine 120 may perform some re-formatting of the content data after download to the mobile terminal in response to user input, for example a user input which modifies a user specified parameter value.
  • An example of formatting data for display is illustrated in Figure 2.
  • the content data may be formatted in two stages with a first formatting stage being performed prior to content access by the mobile terminal and the second stage performed as the content data is streamed to the mobile terminal either at the point of transmission or at the mobile terminal.
  • the content data may be partially formatted based on preset parameter values prior to streaming the content data to a target mobile terminal, as the content data is streamed to the target mobile terminal it may be divided into segments of a given size based on parameter values for the target mobile terminal. This dividing into segments may be performed by the streaming server or by the mobile terminal as the content is received.
  • content data may be pre-formatted for display on a mobile terminal and include embedded formatting instructions.

  • a mobile terminal can also be a content provider as well as a content acquirer, for example where terminal to terminal data sharing or transfer is possible.
  • a method of formatting content for display on a mobile terminal is proposed where the content data is divided into a sequence of consecutive segments according to predetermined parameters. Some of the parameter values may be based on the display capability of the mobile terminal.
  • the formatting method enables content objects, such as text, images, hyperlinks, animations, video clips, data entry fields, audio files, or other types of non-text content to be replaced by markers.
  • Each marker is linked to the associated content object using linking data which can be used to retrieve the replaced content data for display in response to a user command.
  • Whether or not some content objects or which types of content objects are replaced by markers when content data is formatted can be based on user specified parameters. For example a user may specify that images are to be replaced but not hyperlinks or text.
  • the markers can be icons or shapes which can appear in line with content text. The style, shape, size, appearance etc of markers can be controlled using user specified parameters.
  • the marker's linking data is used to retrieve the associated content object in response to a user command.
  • the content objects may be subject to some processes for preparing the content object for rendering on the mobile terminal. Such processes can include, but are not limited to, any one or more of reformatting, resizing, image or video resolution reduction, sound quality reduction, data compression etc. Such processes can reduce the amount of data required to be downloaded to the mobile terminal and/or reduce the amount of processing required to be performed at the mobile terminal to render the content object.
  • the text can be divided into segments based on at least one predetermined parameter value. For example, the text segment size may be based on screen width.
  • Replaced content objects may be downloaded along with the content and stored in device memory for retrieval using the linking data in response to user commands.
  • the replaced content objects are not downloaded with the formatted content but downloaded selectively in response to user commands to retrieve the selected object. It should be appreciated that this enables a user to control and potentially minimise the amount of data downloaded to the mobile device, by only retrieving data for content objects which are selected by the user.
  • Some embodiments also enable a user to edit or annotate downloaded content.
  • the user's edits or annotations can be added to the user's version of the content using markers.
  • a user may edit the content by overwriting some text.
  • the overwritten text may be stored as a content object associated with a marker indicating where the user edited the original text.
  • a user may wish to record their thoughts in respect of a portion of the content and a marker can be added for an annotation.
  • the user may type or record their comments using a voice recorder or voice to text.
  • comments may be captured as images of handwriting using a touch screen or using handwriting to text conversion.
  • photographs, drawings, images, animations, videos or sound recordings may also be appended to content using markers.
  • the marker is added to the sequence of segments and the associated content object can be stored locally on the user's device.
  • the user created marker and content object can also be transmitted for storage with the original content or a user's version of the content, for example on a server or PC.
  • new content objects may be inserted into the displayed content rather than using markers.
  • markers from original content may invite the user to enter data.
  • the original content is a survey, form, test etc
  • the original content may include data entry fields, check boxes, spaces etc for a user to enter data.
  • the formatter is adapted to identify such content fields and associate each field with a data entry marker.
  • the content object associated with the data entry marker is editable by the user. For example, when a user selects a data entry marker the associated content object is opened in an editable manner to invite the user to enter data.
  • Data entry may be selecting an option, for example in the case of a multiple choice question, or entering content by typing, writing using a stylus, audio recording, voice to text, taking a photograph or video, etc.
  • the difference between a data entry marker and a user created marker is that there may be limitation on the type of editing allowed for the data entry marker and associated content object. For example, changing the position of data entry markers may be inhibited. Further, the user does not need to select an edit option for the data entry marker as the content object will open automatically in an editable mode.
  • the data entry marker may open in a predetermined editing mode, for example the content object, when opened, instruct the user to perform an action such as take a photograph using the mobile terminal and automatically switch the mobile terminal camera to an operational mode.
  • the content object may be opened in a user preferred editing mode, for example voice to text, automatically detected from user preferences stored in the mobile terminal.
  • the mobile terminal application may be adapted offer choices for data entry, for example using keypad, voice recording, voice to text, handwriting on a touch screen etc, for selection by the user.
  • the mobile terminal may also automatically detect the method being used to enter data rather than requiring the user to make a selection. For example, as a user starts to enter data using a keypad, then this method is selected, alternatively if a user begins speaking a voice recording or voice to text mode is automatically selected.
  • An advantage of using the markers is enabling easy reading of content on a small display screen of a mobile terminal.
  • This formatting method is particularly well suited for re-formatting content such as web pages for display on a mobile terminal.
  • content such as web pages for display on a mobile terminal.
  • web pages contain a combination of text images and hyperlinks, and often hyperlinks appear in line with text or text wraps around images. This can cause difficulties when trying to read the content on a small display, such as typical for a mobile terminal. Formatting such content using markers to replace some content objects in line with text can make the content more readable on a small display.
  • embodiments where content object data is only downloaded for selected objects provide a user with a high level of control over the amount of data which is downloaded. Markers can also be used to selectively replace some text content.
  • an article may comprise a plurality of text portions, such as a title, abstract, body text and references.
  • User preferences may define that the body text and references text be replaced with markers, leaving only the article title and abstract to be formatted into text segments for download and display.
  • a marker is created for each of the body text and references, which in turn are stored as content objects associated with the created markers.
  • the title text and abstract text are displayed and the body text marker and references marker are displayed after the abstract text.
  • the user chooses to read the full article after looking at the abstract, then the user can select the body text marker.
  • the body text content object can be downloaded and displayed.
  • the formatter may be adapted to selectively replace text using markers based on the text type in accordance with user preferences.
  • the markers can also be used for scrolling through the content.
  • Step 201 indicates the start of the formatting.
  • the formatting component 120 determines the segment size for the mobile terminal based on predetermined parameters in step 202.
  • the segments are based on device display capability parameters such as screen size and resolution as well as user specified parameters, such as font size, colour mode, automatic scrolling mode or one-screen-at-a-time display mode.
  • the segment size may be based on the number of characters displayable across the screen for a particular terminal screen size and user designated font size.
  • Predetermined parameters can also indicate types of content objects which are to be replaced using marker segments. For example user parameter values can be used to specify that all content objects are replaced by markers, selected types of content may be replaced by markers or no content is to be replaced by markers. Any content not replaced by markers will be appropriated reformatted for display along with the text portions of the content.
  • the content data is read in step 203.
  • the manner in which the content data is read for processing will vary depending on the type of data and how the data is provided to the formatter and for download to the mobile terminal. For example, where content is streamed to a mobile terminal, the content data may be formatted for the mobile terminal as it is streamed. Alternatively this step can include a step of retrieving a content data file from a server or database etc.
  • step 203 may include an initial content data conversion step.
  • this may comprise reformatting a document, such as a PDF, HTML or rich text document to convert the document to an XML or plain text and non-text content data format, such as a text and image format which strips out unnecessary data such as text formatting, page boarders or wallpaper images.
  • This step 203 may also include a mapping step where the layout of text and non-text content portions is analysed to determine a formatting order for portions of the content.
  • This step of reading the content data enables the formatter to determine the types of data comprising the content. This in turn enables the content data to be divided into portions based on the content data type. For example, sections of text, images, hyperlinks, video clips etc can all be treated as separate portions of the content by the formatter.
  • the output of this step may be a dynamically allocated array of strings representing each of the portions of the content as separate strings. In an embodiment implemented using Java scripting language this output may be a vector of strings representing text, links, images etc.
  • text can be divided into one or more text segments, which can stored as one or more text content objects associated with one or more marker segments or displayed on the mobile terminal.
  • Non-text content can optionally be replaced with marker segments or formatted appropriately for the non-text content based on one or more predetermined parameter values, such as image size and resolution reductions based on target device display parameters and user preferences.
  • the first content portion is identified in step 204 and the type 205 of content comprising the portion determines the next processing steps.
  • a new text segment is started and a segment pointer is initiated (for the first segment) or incremented (for subsequent segments) in step 210 the size of each text segment is based on predetermined parameters, for example text segment size can be determined based on the number of characters which may be displayed across a mobile terminal display given the user allocated font size.
  • text data is allocated to the segment. Depending on the amount of text data in the portion more than one text segment may be required. If the portion is not fully allocated 214 then the segment pointer is incremented in step 216 and the formatting repeats steps 212 to 214 until the portion is fully allocated into a number of segments. Once the portion is fully allocated 214 attributes can be applied to the segments to transform the text segments into one or more text content objects.
  • processing and content attributes for use by an application player can be applied.
  • the original content data can be transformed into a new content object including scripting representing processing and content attributes whereby formatting instructions are embedded in the content.
  • the scripting is executable by a generic browser to enable enhanced formatting and display functionality.
  • the text portion processing then ends 218 and the formatter looks at the next portion 240 and, provided the end 245 of the content data has not been reached, continues to process the next portion based on type 205.
  • text or some types of text may be replaced by markers.
  • the formatter may perform the above formatting steps and generate marker segments associated with each text content object.
  • the above formatting steps may be omitted and a text portion for replacement transformed in to a single text content object to which attributes are applied.
  • a marker segment can be generated for the text content object including linking data to the text content object.
  • the text content object may be subject to further processing, as described above, when display of the content object is requested.
  • the formatter checks predetermined parameters to determine whether the non-text content object should be replaced by a marker segment or not 220. Whether or not to replace the non-text content with a marker may depend on the content type. For example, user specified parameter values may indicate that all images, video clips, animations and audio files are to be replaced with markers but not to replace hyperlinks.
  • the formatter will create a marker segment comprising a marker 222 and link data 224 associated with the replaced object.
  • the marker 222 can be an icon, shape or other indicator which can be displayed in line with the text when displayed on the mobile terminal.
  • other types of indicators can be a generic image representing a marker type or a small image representing the original image.
  • the marker may be a side bar, border, frame or divider around beside or dividing displayed content.
  • the size, colour or shape of the marker may be used to distinguish between content types.
  • the size of the marker and other aspects of the markers appearance when displayed can be controlled by the user through setting parameter values.
  • a number or letter may optionally be displayed in a marker which may be used as a navigation aid.
  • the link data 224 is used to associate the marker with the replaced object and can be used to retrieve the replaced object data in response to a user command. Additional data may also be included in the marker segment depending on the embodiment. Depending on the embodiment attributes can also be applied to the content object. For example, processing and content attributes for use by a player application can be applied to the content object. In some embodiments the original content data can be transformed into a new content object including scripting representing processing and content attributes executable by a generic browser to enable enhanced formatting and display functionality. In an embodiment implemented using Java language each marker segment can be represented as a token object.
  • all content data is replaced by marker segments and whether or not associate content objects are displayed initially, without a user command, can be based on player parameter values. For example, a user may set player options in a player application of their mobile terminal to display all text content automatically and to display non text content only in response to user commands. Thus, when a sequence of marker segments is acquired by the mobile terminal the content objects associated with text markers are automatically displayed and only markers displayed for all non-text content objects.
  • a different marker can be used for each content object type to give a visual indication of the type of replaced content, for example rectangles may be used for image markers, ovals for hyperlink markers, stars for audio files, pens for data entry markers etc.
  • Markers associated with text or hyperlink content objects may also include the first word of the text content or hyperlink title. The word may be highlighted using a different, colour, background, font, formatting, etc to distinguish the marker form the surrounding text. Alternatively, a border, side bar, underline, section divider, frame etc may be used as a marker. Special images or animations may also be used to represent markers. The nature of the marker or attributes of the marker such as colour, position, size, etc may be used to distinguish between marker types.
  • a marker segment can comprise additional data associated with the object or marker and this data can be optionally displayed based on user specified parameter values or user commands.

  • the size of text segments adjacent a marker may be adjusted to allow space in the line when for the marker when displayed. For example, if a marker takes up the equivalent space as two characters when displayed, this can be taken into account when determining the segment size for a first text segment following a marker segment.
  • the text segment size can be reduced based on the number of character spaces, displayable on the mobile terminal display, which have been occupied by other text and markers on the display line.
  • content objects can be optionally replaced based on defined parameter values.
  • the formatter may perform some formatting of the object 230 for display. For example, for image or video data the display size and resolution may be adjusted, based on defined parameter values, for display on the small display of the mobile terminal. This can reduce the amount of data required for download to the mobile terminal to reproduce the image or video. The quality of the video or image reproduction may also be reduced to match the capability of the mobile terminal. Quality reduction may alternatively be defined by the user by setting parameter values in order to further reduce the amount of data required to download. For example, a user may be able to specify a target resolution for images and video or a qualitative parameter value may be set.
  • “best”, “optimised” and “low” resolution parameters may be set by the user.

  • “best” may be associated with the highest possible resolution that can be achieved for the target device display.
  • “Optimal” may be associated with an algorithm which determines a compromise between a target resolution and a download data size target.
  • “Low” may be associated with a minimum target resolution.
  • Data compression and codec conversion may also be used to minimise the amount of data downloaded. Similar reformatting or reduction in quality can be used for audio files to minimise the amount of data downloaded.
  • audio files in wave (.wav) format may be converted to MP3 format to take advantage of the smaller file size for MP3 files.

This may optionally involve downloading the data for the content object from a server 955. Alternatively the data may already be stored in device memory. For example, in an embodiment where content object data associated with each marker is downloaded along with the formatted content data, the associated data can be stored in locally device memory, thus the content can be retrieved even if the device goes offline or disconnects from the content server. In this case when the user give a command to retrieve the content object data the data is simply retrieved from device memory.
  • This retrieval step could include a step of formatting the content object data for rendering on the mobile terminal, for example reducing the size and resolution of an image or video before downloading to the mobile device, or dividing text into a sequence of segments. This step may not be necessary if the content object has already been optimised, if necessary, for the mobile device.

Displaying the content may also include display effects such as zooming out of a marker, flipping/rotating an image or scrolling the content onto the display. The display positions of the originally displayed content may be adjusted to accommodate the retrieved content data. For example, text may be scrolled off the display or replaced by the retrieved content. Once the user has viewed the retrieved content the user can continue scrolling through the content and the retrieved content removed from the display or scrolled off the display as the user resumes viewing the content.
