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.

Extracting document data from multiple sources for display on a mobile communication device using HTTP request headers having XML strings therein

A method for downloading an attachment to an attachment viewer of a portable electronic device includes: sending an initial data request from the attachment viewer to a server in response to receipt of an email message including the attachment, building and storing a graph structure within the server representing a map of the attachment, encapsulating the graph structure in data having an attachment viewer readable format and sending an initial chunk of the data to the attachment viewer, the initial chunk of the data being stored on the portable electronic device. The initial chunk of the data is received by the portable electronic device prior to a request to view the attachment being selected by a user.

Method for receiving email attachment on a portable electronic device

A method, system and apparatus for management of push content is provided. An intermediation infrastructure mediates traffic from a push content server that is addressed to a computing device. The intermediation infrastructure enforces various policies such that, for example, unwanted communications are not pushed to the computing device.

Method, system and apparatus for management of push content

A method and apparatus for providing rich content to media devices are disclosed. Information content is converted at a content provider system for transmission to a media device over a wireless communication network. The converted content is processed by a media engine on the media device. The content is preferable converted at the content provider system into a binary format having separate visual elements and behavior elements.

Method and apparatus for providing content to media devices

A method for downloading data from a server to a portable electronic device operating on a wireless network includes determining a network speed of the wireless network, setting a chunk size based on the network speed, sending a request to the server including the chunk size and receiving data from the server in chunks having the chunk size.

Adjustable download rate for a portable electronic device

A method for downloading an attachment to a portable electronic device's attachment viewer includes: sending an initial request from the attachment viewer to a server in response to receiving an email including the attachment by the device; from the server, accessing a graph structure representing a map of the attachment previously built on the server; reconstructing the graph structure in response to the request and encapsulating the graph structure in data having an attachment viewer readable format; (i) downloading successive chunks of the data from the server to the attachment viewer responsive to successive requests; (ii) storing each of the successive chunks on the device prior to display thereof; (iii) displaying the successive chunks on the device and automatically downloading respective next chunks of the data from the server; and (iv) while chunks remain to be downloaded from the server performing (i) to (iii).

Method for pre-fetching data chunks of an email attachment on a portable electronic device

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.

Method of remotely controlling a presentation in loop mode using a portable electronic device

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.

Method and apparatus for uniform presentation of documents on a mobile communication device

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.

Method of remotely controlling a presentation to freeze an image using a portable electronic device

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 of said data from said server; and iv) while said data chunks of said data remain to be downloaded from said server performing steps i) to iii).
