Definition
Multimedia metadata describes various aspects of multimedia content, including formal and technical properties (e.g. encoding, format), information about the creation of content, the processing applied, its use, rights information and the structure and semantics of the content itself. The importance of these aspects depends on the role of the provider or consumer of the metadata and the stage in the media life cycle. Multimedia metadata is among others important for production, distribution, search and indexing of multimedia content.
Introduction
Multimedia metadata is data describing various aspects of multimedia data. In general, one can distinguish between low-level and high-levelmultimedia metadata. Low-level metadata can be extracted automatically and describes characteristics like color, texture or shape in case of visual information or like timbre, pitch and...

KLV (Key-Length-Value) encodes items into Key-Length-Value triplets, where key identifies the data or metadata item, length specifies the length of the data block, and value is the data itself [16].
