Abstract

A system and method for transcoding digital content (e.g. web content) by correctly employing one annotation for multiple digital contents. This can efficiently reduce the workloads required for the addition of annotation data during the transcoding process. A transcoding system comprises an annotation database system for storing annotation data to be used for the transcoding of contents, and a transcoder for transcoding the contents based on annotation data stored in the annotation database system. Upon receiving an inquiry from the transcoder, a correlation between elements in the contents and descriptions of the annotation data is checked to select one annotation that can be employed for transcoding the content. The correlation is specifically determined based on XPath information.

Claims

1. A computer-readable recording storage medium storing annotation data to be used in a transcoding process of digital content, the computer-readable recording storage medium comprising computer executable program code for:

reading said annotation data to be used in a transcoding operation, said annotation data is stored in annotation files that are prepared for units of digital contents,

the annotation data including descriptions for the transcoding process, the descriptions being correlated with a layout of elements in the digital contents; and

wherein said annotation files are sorted based on location information of the digital contents on a network;

selecting an annotation corresponding to the digital content based on correlation between a layout of the digital content and descriptions of the annotation data; and

transcoding the digital content based on the selected annotation.

2. The computer-readable recording storage medium according to claim 1, wherein the descriptions in the annotation data are correlated with the layout of the elements in the digital contents by using XPath.

3. The computer-readable recording storage medium according to claim 1, wherein the annotation data include information for identifying an element in the digital content for which a layout change is planned.

4. The computer-readable recording storage medium according to claim 1, wherein said annotation files are sorted based on URLs (Uniform Resource Locators).
