System and method for transcoding information for an audio or limited display user interface
First Claim
1. A method for transcoding information provided in a first markup language, the method comprising:
- selecting a portion of the information;
determining a complexity of the selected portion;
preparing, if the complexity of the selected portion exceeds a limit, a hypertext link and a subset of the information, the hypertext link for accessing the subset of the information;
providing at least one of the selected portion, the hypertext link, and the subset; and
providing an annotation associated therewith.

Abstract
A system for voice browsing or transcoding permits access and navigation to information via an audio user interface or a limited display user interface. The audio user interface permits speech or telephone keypad input to interrupt the presentation of information, for example, to direct following a hypertext link. When operating with the Internet, the user of one or more access devices including a cell phone, telephone, portable computer, or workstation may request a web page by providing an address. Guidance may be prepared ahead of time by the user operating an editor. Guidance may direct summarization, selection, annotation, and restatement of the requested content. Guidance may include statements of a markup language that include a structural summary description of the content or a hidden Markov model. To allow for frequent changes in the arrangement of content on web pages provided by the Internet, portions of the content are identified for the application of particular guidance by aligning a structural summary description of the current content to the structural summary description stored with the guidance. Guidance suitable for particular content may be located on the basis of an address of the content (e.g., a URL), of a related address, or of being within the scope of a regular expression. Guidance produces derivative content which may be easier to understand when presented in audio or easier to understand when presented on a display of limited area or resolution. Derivative content may include a set of web pages hierarchically organized with connecting links. The complexity and importance of regions of the requested web page are assessed in developing the hierarchy and organization of the set of web pages to be presented. Each web page may then be expressed in a voice mark up language and presented through a speech engine to the user. Information from the requested web page may be presented on the same or a different access device.

8. A method for developing guidance for a transcoding process, the method comprising:
-
receiving information in accordance with a first markup language;
presenting a plurality of portions of the received information;
associating an annotation with a selected portion; and
storing the association, the annotation, and the selected portion in accordance with a second markup language, the first markup language and the second markup language each having at least one pair of tags unique to the respective language. - View Dependent Claims (10, 11, 12)

13. A method for transcoding information provided in a first markup language and associated with a first Uniform Resource Locator, the method comprising:
-
obtaining guidance in accordance with at least a portion of the first Uniform Resource Locator, the guidance comprising a first description and an annotation;
preparing a second description of at least a first portion of the information;
determining a correlation between the first description and the second description;
providing, if the correlation exceeds a limit, at least a second portion of the information and the annotation. - View Dependent Claims (14, 15)
