User requirements for Metadata related to digital production,
post-production, recording and archiving of sound
and television Programmes in broadcasting
Introduction
With every multimedia content, there is lot of associated information. In days of analog, this information about the content was kept in the form of a paper datasheet. Sometimes database entries were made in the computers, with a unique media identifier number marked on the media envelope. In case of loss of datasheet or unique identifier, the whole information about the content was lost.
With the advent of Digital technologies, similar process used to be in place. Content and information about the content used to be kept separately in servers and databases. Many a times, content is removed from server, but database entry remains there; and synchronization of database & Audio files is a tedious process. Every time file is copied, its associated information has to be manually entered into the database. Sending content for exchange within the organization still requires need of sending the information in the form of a paper or separate Computer file in this case.
The advancement in digital technologies in the field of broadcasting has made it possible to include the information about the content file itself. This associated information is called Metadata. This has many benefits. The Database can read the metadata directly from the file. There is no need to send the information about the content separately while sending the content for exchange. However, it is desirable to have standard terminologies, formats etc. for the metadata structure and its scheme of embedding so that there are less chances of its misinterpretation and loss.
ITU-R Question 46-1/6 pertains to various aspects related to Metadata for production and post-production in broadcasting. The present document addresses these aspects and tries to find out suitable answers to queries raised in ITU-R Question 46-1/6.
2 Various functions of metadata
The following functions are expected of metadata:
It should help in selecting proper playback application/module/software depending upon the format of the content.
It should support all the standard Broadcast formats.
It should not hinder/disrupt playback of the content.
Metadata should also not degrade the playback quality of the multimedia.
It should be able to indicate the ownership and distribution rights of an organization/company over the content.
It should be able to help in searching/Browsing/viewing the content on Content’s General & intellectual Information
A few fields in the Metadata should be editable only by the owner.
The metadata information should be directly accessible through the databases for search etc.
3 What information should be provided in the form of Metadata accompanying digital recordings of sound and television programmes?
Information in the form of eighteen elements can be accompanied with digital recording of sound and television programme.

The Recommended best practice is to use a unique identifier to identify the physical source that has been used to create the digital resource. In the case of a digitized analogue recording, it is the recording used for digitization which is the source. For commercial recordings the label and number is normally given.
Element 15: Language
Name: Language
Definition: A language of the intellectual content of the resource.
Comment: Recommended best practice for the values of the Language element is defined by RFC 1766 [26], which includes a two-letter Language Code (taken from the ISO Standard 639 [27]), followed optionally, by a two-letter Country Code (taken from the ISO Standard 3166 [28]).
