Abstract: A method for presenting an attachment within an email message on a display of a portable electronic device includes displaying the email message using a messaging application, sending a conversion request to an attachment server in order to view the attachment in an attachment viewer of the portable electronic device, receiving a converted attachment from the attachment server; and upon receiving the converted attachment from the attachment server, inserting a thumbnail image in a message body of the email message.

Abstract: A method operable on a mobile communication device, comprising opening a browser session and issuing an HTTP request for document data, wherein the request includes an XML descriptor added to headers of the HTTP request for identifying the request and the document data being requested, and receiving an HTTP response including the XML descriptor along with document binary data representing respective chunks of the document data for display on the mobile communication device.

Abstract: A system and method are set forth for remotely controlling a presentation in a loop mode to allow the presentation to continue in the absence of a communication channel between the portable electronic device and remote presentation device. In particular, the portable electronic device can issue a command to the remote presentation device to present the presentation in loop mode so that a user of the portable electronic device can leave the vicinity of the remote presentation device (e.g. out of communication range) while the presentation plays in loop mode.

Abstract: A mobile communication device, comprising a display, a persistent store, at least one input device, and a processor for executing (i) an invoking application for generating a request for document data responsive to an input via the input device, (ii) an attachment viewer for receiving the request and generating a command for chunks of document data, and (iii) a listener interface for receiving a response to the command and passing the chunks to the attachment viewer for displaying respective chunks of said document data via the display.

Abstract: A system and method are set forth for remotely controlling a presentation from a portable electronic device so as to freeze a slide on a remote projector to permit searching for a desired slide on the portable electronic device and then continuing the presentation when searching is complete. In one embodiment, a switch is provided in a communication layer of a presentation application such that when the switch is turned off, communication is suspended between the portable electronic device and the projector, thereby permitting browsing on the portable electronic device without interrupting the presentation. When the switch is turned on the current slide information is transmitted from the portable electronic device to the projector.

Abstract: Method for viewing an attachment of an email message on a portable electronic device in which the attachment has a renderable format is provided. The method includes: requesting to view the attachment in an attachment viewer of the portable electronic device, building a graph structure within an attachment server representing a map of the attachment, the graph structure including at least one renderable identifier corresponding to a page of the attachment, requesting rendering of the attachment, the rendering request being send from the attachment viewer to the attachment server and including the at least one renderable identifier, initializing a rendering library and storing rendering commands corresponding to command types of the graph structure in the rendering library, drawing the rendering commands in an off-screen bitmap, saving the off-screen bitmap as a JPEG file, sending the JPEG file to the electronic device and displaying the JPEG file in the attachment viewer.

Abstract: A method and portable electronic device for processing images are provided. Images are stored electronically at a remote server as attachments to message data, message data received at the portable electronic device with indicators identifying corresponding attachments to the message data. The portable electronic device comprises a processing unit interconnected with an input device, and a display device. First input data is received indicative that one of the indicators, corresponding to one of the images, has been selected, causing the image to be retrieved from the remote server. The received image is displayed at the display device. Second input data is received indicative that a next one of the images is to be displayed, the second input data received while the first retrieved images is displayed at the display device. The next images is then received from the remote server and processed to display it at the display device.

Abstract: A method for downloading an attachment to an attachment viewer of a portable electronic device includes: sending an initial data request from said attachment viewer to a server in response to receipt of an email message including said attachment by said portable electronic device; accessing a graph structure representing a map of said attachment from said server, said graph structure having been previously built on said server; reconstructing said graph structure in response to said initial request and encapsulating said graph structure in data having an attachment viewer readable format, said data being stored on said server; and i) downloading successive chunks of said data from said server to said attachment viewer responsive to successive user requests; ii) storing each of said successive chunks of said data on said portable electronic device prior to display thereof; iii) displaying said successive chunks of said data on said portable electronic device and automatically downloading respective next chunks
