Metadata
This article explores some of the possibilities for efficiency gains and cost savings by using embedded metadata specified by application specifications such as the Digital Production Partnership from the UK that is based on AS-11 from Advanced Media Workflow Association (AMWA). Information about media is just another way of saying metadata, and metadata is the key to getting good file-based automation.

Packaging with MXF: A tool for IPTV content
New delivery channels such as IPTV and mobile are creating opportunities for broadcasters and content owners to reach consumers with new and existing content. How can technology help to ensure that this is done cost-effectively, both in the rollout stages and in the mature market phases of these new channels? This article covers the basics of mastering and repurposing and will look at issues that affect reusability of content, picture quality and the consumer's experience of these new channels. End users designing a facility often choose operational file format/compression systems based on what they already have and their current needs. The end result is that facilities have different native file formats in operational use. Over time, this means vendors will have to implement all the file formats in order to interoperate properly. This requires massive engineering overhead - a cost passed on to the end user. The MXF file format was designed to take into account this precise scenario. To use MXF as a master file format for cost-effective IT-based content delivery, it is necessary to manage MXF's complexity. This involves defining rules for operational use of the files and defining metadata for indicating language variants. And it requires vendors working together to achieve good interoperability.

4 Operational Patterns and Constraining MXF
Operational patterns are the way of controlling the complexity of MXF Files. Various names were tried during the design of MXF; for example, \"templates\" was rejected because it was already laden with expectations that differed depending on whether you came from a video or a software community. \"Profiles\" was rejected because there is a well-known video server with this name. \"Operational patterns\" was chosen because it had not already been used and conveyed the idea of the operational use of MXF. The design of the generalized operational patterns that appear in the MXF File Format Specification was governed by the desire to limit the complexity of encoders and decoders to acceptable levels. It was envisaged that specialist operational patterns would be created to cover the requirements of specific application areas such as non-linear editing and \"live\" file usage.

12 Index Tables
An index table allows an application to convert a time offset to a byte offset within a given stream in a file. This allows applications to access any frame or sample within the file without having to parse the entire file. The general concepts for the use of index tables were first introduced in Chapter 2. The detailed construction of index tables is given here. Further information for specific stream types such as MPEG and audio is given in the respective chapters.

6 Audio in MXF
MXF categorizes essence into picture, sound, and data. Sound essence covers uncompressed and compressed audio whether it be mono, stereo, multi-channel, or multilingual. MXF is intended for the interchange of complete or finished material. Although MXF can represent cut edits, it is not intended to be a fall audio editing language, nor is it intended to be a full N channels from M sources crossbar-routing language.
