Virage Video Engine Architecture

Media Object: Encapsulation around datatype. Isolate engine from specific details of various formats such as MPEG, AVI, Quicktime, etc.

Primitive: Encapsulation around the index extraction and comparison functionality to support different media types uniformly.

Analysis phase: Insertion operation. Primitive performs data analysis and
returns compact representation feature vector.

Comparison phase: Query operation. Primitive uses feature vector to

generate responses to queries.

Other concepts: weights, scores, and schemas for managing and combining outputs from primitives
