A multi-window user interface (UI) is presented in various configurations and operational uses to leverage the relatively large display canvas afforded by large screen display devices such as 4K or 8K displays. Along with the various Multiview aspects, content delivery techniques, content selection techniques, and level of service techniques also are presented.

An iTV user interface includes a navigable menu area through which a user can select from among a variety of services and a content display area in which formatted data associated with a selected menu service are displayed to the user. The formatted data is displayed in a rotating or ticker fashion having both a passive mode, in which the formatted data is displayed in a sequence independent of any selection operations by a television viewer, and active mode, in which the formatted data is displayed in a sequence that depends on selection operations by the television viewer. Advertisements and/or promotions may be interspersed among the content items. The navigable menu area and the content display area may be displayed to the viewer at the same time as television programming is displayed on the television.

A method of processing a broadcast signal is discussed. The method includes generating service components of a broadcast service; generating first signaling data and second signaling data, the first signaling data for locating the second signaling data, the second signaling data signaling the broadcast service; processing the service components and the second signaling data into transport packets, wherein the first signaling data includes destination Internet Protocol (IP) address information, a destination port number, and source IP address information through which the second signaling data is delivered; and transmitting the broadcast signal including the first signaling data and the transport packets.

There are disclosed various methods, apparatuses and computer program products for video encoding. In some embodiments a method comprises: obtaining a coded first image and a coded second image, wherein the coded second image depends on the coded first image; determining that, when displaying a decoded second image that is decoded from the coded second image, it is allowed to first display a decoded first image that is decoded from the coded first image; and in response to said determination: including the coded first image into a first image container file and including the coded second image into a second image container file; indicating, in a markup language code, that a first image container file and a second image container file are alternatives; and indicating, in the markup language code, that the second image container file depends on the first image container file.
