Abstract

A system for generating, transmitting, providing and/or receiving broadcast service signaling.

First claim

1 . A method for decoding a service guide associated with a bitstream comprising:
(a) receiving a service list table within said service guide that includes a service list table element that is a root element of said service list table; (b) receiving a sltInetUrl element that is an element of said service list table element that indicates a base URL to acquire electronic service guide or service layer signaling files available via broadband for services in said service list table element; (c) receiving a first urlType attribute that is an attribute of said sltInetUrl element that indicates types of files available with said base URL; (d) receiving a service element that is an element of said service list table element that indicates service information; (e) receiving a serviceld attribute that is an attribute of said service element that identifies said service element within the scope of a broadcast area; (f) receiving a svcInetUrl element that is an element of said service element that indicates a URL to access Internet signaling for a service; (g) receiving a second urlType attribute that is an attribute of said svcInetUrl element that indicates types of files available with this URL; (h) receiving a broadcastSvcsSignaling element that is an element of said service element, if said broadcastSvcsSignaling element is present in said service list table, that provides broadcast signaling related information; wherein at least one of (A) when said broadcastSvcsSignaling element is not said present in said service list table said svcInetUrl element is present and said second URLtype always has a value of 1, and (B) when said broadcastSvcsSignaling element is not said present in said service list table said sltInetUrl element is present and said first URLtype always has a value of 1 and supports said serviceld attribute path term; (i) decoding said service guide.
