`
`Scope
`
`The present document specifies the architecture and functions ofan IPTV system that makes use of the NGN IMS
`architecture and its features.
`
`The present document has taken IPTV solutions defined by other organizations (such as DVB, ATIS IIF etc) into
`account. It is based on an IMS based architecture and where appropriate the aforementioned solutions are referenced.
`
`By relying on common components the resulting architecture can coexist with other TISPAN NGN services.

`offset: value indicating the elapsed time between the beginning of content and the current reading position of the
`reading cursor in that same streamed content
`
`park TV: feature that would enable a user (on a UE) make an impulsive request to record ongoing BC

`
`NOTE: This recording point is also referred to as a bookmark.
`
`park and pickup TV: feature that would enable a user (on a UE) to Park TV and subsequently Pickup TV

`NOTE 1: The specification of management functions and content provider functions is considered out of scope of
`the present document
`
`User equipment:
`
`UE: The IPTV enabled UE terminates the IPTV control and media signals, and displays the corresponding information
`to the user. The UE interaction with the user allows selection of programme, content, and service descriptions, such as
`content guides for broadcast and VoD services.
`
`Application functions & IPTV service functions:
`
`Enables operation of or provides IPTV services. This includes IPTV Service Supporting Functions.
`
`IPTV Service Supporting Function: The IPTV Service Supporting Function defined here are those common functions
`which could support or be used by other IPTV service or applications.
`
`NOTE 2: Examples ofIPTV service supporting functions may be Service Discovery and Selection functions.
`
`User Profiles:
`
`User Profiles includes user data that are involved in providing IPTV services.
