Digital broadcasting services have started. Information Broadcasting 
Laboratories (IB Labs) proposed "Program Index" that is a kind of metadata added
 to the TV program. The terminals (STB) regenerate the stored programs in 
accordance with the scenario described in Program Index.
We are now examining this Program Index to apply to the searching and managing 
system of the stored programs. 

Now, Once the TV programs had been stored in the local media the broadcasters 
don't have any method querying to the terminal system. For example, a 
broadcaster can not delete a stored program which is passed a fixed term. In 
order that the broadcasters manage the programs stored in the terminal, the 
system is required to execute specified actions (querying to delete said program)
 when specified events (passed a fixed term to watch) arise.

We are now approaching from the TV program contents, but it is desirable to 
apply to the contents on the Web. It will bring us a real seamless information 
access.
We would like to propose the formalism of query related in the specified event 
as the extension of the Query Language.
