The increasing amount of digital audiovisual information and the need to efficiently and effectively describe and retrieve this information as well as the big technological developments in the related domains have been acknowledged by the MPEG (Moving Pictures Experts Group) standardization group which initiated a new work item, formally called “Multimedia Content Description Interface” but bet...

Many features of traditional TV service are becoming desirable for software multimedia applications to provide open solutions and improve flexibility. In this work, we have studied a new kind of service, what we call “visual information embedding”, that comes from the idea of Picture-In-Picture. Based on previous work in MPEG-compressed domain algorithms, we propose a “backtracking” approach th...

As more and more multimedia content is delivered and stored in the MPEG-2 format, there is an increasing interest in developing processing techniques that can be applied directly to the compressed domain. In applications such as video browsing, picture in picture and in the forthcoming broadcast of high definition digital television (HDTV) to the home there is a need for spatial downscaling of ...

English-speaking college students who were enrolled in a German course read a 762-word German language story presented by a computer program. For key words in the story, students could choose to see a translation on the screen in English (i.e., verbal annotation) or view a picture or video clip representing the word (i.e,, visual annotation), or both. Students remembered word translations bette...

This paper describes LEFTY, a two-view graphics editor for pictures in various contexts. This editor has no hardwired knowledge about specific picture layouts or editing operations. A picture is described by a program containing functions to draw the picture and functions to perform editing operations appropriate to the specific picture. Primitive user actions, like mouse and keyboard events , ...
