Stream - based Versus Structured
نویسندگان
چکیده
An emerging area of database system research is to investigate techniques that ensure a continuous display of video objects. As compared to the traditional data types, e.g., text, a video object must be retrieved at a prespeciied rate. If it is retrieved at a lower rate then its display may suuer from frequent disruptions and delays, termed hiccups. This paper describes two alternative approaches to representing video objects (stream-based and structured) and the issues involved in supporting their hiccup-free display. For each approach, we describe the existing solutions and the future research directions from a database systems perspective.
