##Introduction##

Public Schedule is an XML format for exchanging data within the TV and broadcasting industry. It's purpuse is to have a common open standard for exhanging information between internal systems at a broadcaster or distributor, as well as exhanging this type of data between organizations.

##The XML structure in brief##

The XML format of Public Schedule is divided in three different structures, Content, Event and Material:

Content contains metadata of programs, such as for example title, synopsis, image and participating actors.

Event contains information about the transmission of the program on a linear channel, such as the channel's name and when the transmission starts and ends.

Material contains technical data of the transmission or video file, such as aspect ratio, resolution and subtitling. Material also contains rights for the programs, for example if it is allowed to be viewed on a tablet or allowed to recorded and then available for on demand.

To represent a program that is transmitted on a linear channel (for example to be able to generate an Electronic Program Guide), all three structures (Content, Material and Event) are needed. Such a case is called "Schedule operation" and is wrapped by a corresponding element in the XML.

To represent a program that is to be published as Video On Demand, only Content and Material are needed. Such a case is called "Publish operation" and is wrapped by a corresponding element in the XML.

==Background==

Public Schedule was invented by a joined effort from two of the major TV-channels in Sweden, TV4 and Sveriges Television. The reason behind the effort was the lack of a common standard within this area, that also would enable to exchange information of new demands for the changes in the way of consuming TV. It was also important that this would be kept an open standard, not proprietary to any of the founders, and that the format should evolve over time. Seeking broad acceptance for Public Schedule is also important for enabling it as a standard. TeliaSonera, one of the major distributors in the Nordics, was an early adopter of the standard. When it was time to develop the next version (4) of Public Schedule, TeliaSonera took the lead, and it was also at this time Junewas involved as contributor.

When TerracomBoxer, one of the other major distributors in the Nordic decided to support this standard, a decision was made within the supporter group to let the Public Schedule standard be supervised by an external, independent organization, and they chose June to perform this duty.
