Content Processing for Data Broadcasting

Ed Casaccia

The emerging business of data broadcasting is creating new requirements for content processing tools and techniques. Just as data broadcasting combines traditional broadcast technology with packetized data transmission usually associated with computer networks, these new content processing requirements combine elements of video production with technologies developed to delivery the huge mass of information available via the World Wide Web. The following is a description of how one data-broadcasting venture, Geocast Network System, Inc. of Menlo Park, California has created new technologies, adapted existing technologies, and developed operational procedures to address these needs. — Although many variations exist among the various content types, the entire endeavor can be broadly characterized in three main steps, euphemistically referred to as “Grab, Bag, and Tag.” “Grab” refers to acquiring the source material that is to be delivered via data broadcasting and, if necessary, converting that material into digital form. “Bag” refers to aggregating material from disparate sources into a single topical grouping, or disaggregating (segmenting) long form material into smaller units defined by topic, source, or any other appropriate delineation. “Tag” refers to the creation, either through human effort or in automated fashion, or a set of metatdata describing the content material.
