What is Content? ► Content is conventionally considered as some form of audiovisual, visual, sound or textual information ► Content according to the formal SMPTE/ EBU definition consists of: ► Essence, i.e. the raw programme material itself  Video  Sound  Images  Text ► Metadata, that describes the essence  Content related data describing the actual information  Material related data describing available formats  Location related data describing location, number of copies, condition of carrier, etc.

Essence Essence is the part of a content object that represents the actual information or message (i.e. the content) encoded in various formats ► Physical Representation of Content ► Audiovisual ► Visual ► Audio ► Textual ► Combinations: Web-pages, animations, etc. ► Types of Essence ► Continuous and discrete media ► Structured essence formats ► Browse and high-resolution formats ► Essence Related Issues ► Different encoding formats  DV vs. MPEG, JPEG vs. GIF, SGML vs. Word ► Different storage formats  Video & data tapes, optical disks, servers, etc.

Metadata ► If you have content somewhere but can‘t actually find it you don‘t really have it ► Content Related Data ► Available content ► Formal data, such as title, sub title, duration, cast, etc. ► Indexing information, such as key words, image content description, classification ► IPR related information, such as rights owner, acquired rights, etc. ► Material Related Data ► Available formats ► Recording specific information ► Location Related Data ► Available copies ► Location ► Physical condition of carrier media

Content Management ► Content Management is the handling, administration and presentation of content (i.e. essence and metadata) in a system context ► Elements ► Essence management  Recording and encoding  Storage management  Content preservation ► Metadata management  Documentation & description  Data and information management ► System interfaces and applications ► Requirements ► Openness, modularity, distribution, integrability ► Automatic handling of essence and metadata ► Automatic information generation ► User friendliness
