Abstract
Transcoding between content data and description data. The transcoding may include transcoding content data to corresponding description data. Additional description information to complete the description data may be requested. The transcoding may include transcoding description data to content data, including seeking content data items that match the description data. Content data items that best match the description data may be selected and included in the content data. A user may be requested to select items from a group of matching content data items. The content data may be stored according to the Moving Pictures Expert Group-4 (MPEG-4) standard, and the description data may be stored according to the MPEG-7 standard. The transcoding may be achieved via rules stored in the Extensible Stylesheet Transformation (XSLT) format. The transcoding may be implemented on a computing device, such as a personal computer.
