Abstract
Abstract A method and apparatus for selecting at least one transcoding method for manipulating multimedia data for delivery on the basis of analysis of the content of the multimedia data. Many possible transcoding operations can be performed on multimedia data to adapt it to constraints in delivery and display, processing and storage of client devices. The selection of specific transcoding operations can be made by first analyzing the features, purposes and relevances of the individual multimedia objects within the multimedia documents, then by selecting the transcoding alternatives according to the results of the analysis. Based on the analysis, different transcoding algorithms can be applied to different content, less than all of the content can be transcoded, groups of multimedia objects can be transcoded, etc.

Claims Analysis
Total Claims: 31
Claim 1
Independent Claim
45 words
A computerized method for transcoding a multimedia presentation for delivery and display comprising the steps of: analyzing the content of the multimedia presentation by separating a multimedia document into individual multimedia objects; and analyzing each multimedia object individually; and performing transcoding based on said analyzing.
Claim 2
Dependent Claim
45 words
A computerized method for transcoding a multimedia presentation for delivery and display comprising the steps of: analyzing the content of the multimedia presentation by separating a multimedia document into individual multimedia objects; and analyzing each multimedia object individually; and performing transcoding based on said analyzing.
Claim 3
Dependent Claim
38 words
The method of claim 1 wherein said performing transcoding comprises the steps of: selecting at least one transcoding alternative based on the results of said analyzing; and transcoding the content according to said at least one transcoding alternative.
Claim 4
Dependent Claim
34 words
The method of claim 1 wherein said performing transcoding comprises the steps of: selecting less than all of said content for transcoding based on said analyzing; and transcoding less than all of said content.
Claim 5
Dependent Claim
28 words
The method of claim 1 further comprising the steps of: separating the multimedia objects into individual modal elements; and analyzing each modal element of each multimedia object independently.
Claim 6
Dependent Claim
28 words
The method of claim 1 further comprising the steps of: identifying relationships between individual multimedia objects within a multimedia document; and transcoding related multimedia objects as a group.
Claim 7
Dependent Claim
28 words
The method of claim 4 further comprising the steps of: identifying relationships between individual modal elements of multimedia objects; and transcoding the related modal elements as a group.
Claim 8
Dependent Claim
18 words
The method of claim 1 , wherein the multimedia content is a document published on the World-Wide Web.
Claim 9
Dependent Claim
13 words
The method of claim 1 , wherein the multimedia content comprises visual content.
Claim 10
Dependent Claim
25 words
The method of claim 8 , wherein the content analysis classifies the visual content into at least one of image type, purpose and semantic classes.
Claim 11
Dependent Claim
20 words
