Abstract

A method is set forth of displaying a document identified by a URL on a mobile browser, comprising registering an attachment viewer plug-in to the mobile browser for a predetermined data stream content type, registering a mobile data service transcoder for predetermined document types, sending a request for the document of one of the predetermined document types from the mobile browser to the mobile service transcoder, retrieving and converting the document to the predetermined data stream content type, and forwarding the converted document from the mobile data service transcoder to the mobile browser for display via the attachment viewer plug-in.

Claims

1. A method of displaying a document identified by a URL on a mobile browser, comprising:

registering an attachment viewer plug-in to said mobile browser for a predetermined data stream content type, wherein said predetermined data stream content type is Universal Content Stream (UCS);

registering a mobile data service transcoder for predetermined document types;

sending a request for said document of one of said predetermined document types from said mobile browser to said mobile service transcoder, wherein said mobile browser adds an indication of said UCS content type when sending said request for said document to said mobile service transcoder;

retrieving and converting said document to said predetermined data stream content type; and

forwarding the converted document from said mobile data service transcoder to said mobile browser for display via said attachment viewer plug-in, wherein said attachment viewer plug-in starts to display said converted document upon receiving an initial portion of said converted document.

2. The method of claim 1, wherein said initial portion is about 3 Kb.

3. The method of claim 1, wherein said predetermined document types are selected from .doc, .pdf, ppt, .xls, .pps, .wpd, and .dot.

4. Apparatus for displaying a document of a predetermined document type identified by a URL on a mobile browser, comprising:

an attachment viewer plug-in to said mobile browser for displaying attachments conforming to a predetermined data stream content type, wherein said predetermined data stream content type is Universal Content Stream (UCS); and

a mobile data service transcoder for receiving a request for said document from said mobile browser, said request containing an indication of said UCS content type, and initiating retrieval and conversion of said document from said predetermined document type to said predetermined data stream content type, and transmitting said converted document to said mobile browser for display via said attachment viewer plug-in, wherein said attachment viewer plug-in starts to display said converted document upon receiving an initial portion of said converted document.

5. The apparatus of claim 4, wherein said initial portion is about 3 Kb.

6. The apparatus of claim 4, wherein said predetermined document types are selected from .doc, .pdf, ppt, .xls, .pps, .wpd, and .dot.

7. A method of displaying a document of a predetermined document type identified by a URL on a mobile browser, comprising:

registering an attachment viewer plug-in to said mobile browser for a predetermined data stream content type, wherein said predetermined data stream content type is Universal Content Stream (UCS);

sending a request for said document from said mobile browser for remote retrieval and conversion of said document to said predetermined data stream content type, wherein said request includes an indication of said UCS content type; and

displaying the converted document via said attachment viewer plug-in upon receiving an initial portion of said converted document.

8. The method of claim 7, wherein said initial portion is about 3 Kb.

9. The method of claim 7, wherein said predetermined document type is selected from .doc, .pdf, ppt, .xls, .pps, .wpd, and .dot.
