Abstract

An interactive digital television broadcast system, including a broadcast operator, is adapted to transmit a downlink digital broadcast stream received from an interactive digital television provider to a plurality of subscriber units. The digital broadcast stream is displayed on multiple subscriber units. The system also includes an interaction return channel operator for providing interaction between a subscriber unit and said provider via a two-way interaction return channel. The system also includes: a content insertion module for inserting content provided by a user unit in the display content of a user unit among a plurality of user units; a shared content retrieval module for retrieving, together with metadata of the shared content, shared by the user unit content reference; a shared content matching module for determining relevant content from the content shared by the user unit by matching the metadata of the shared content with at least one predetermined criterion; a content suggestion module for suggesting to the user unit when the user Insert related content into the displayed content of the cell.

Description

technical field [0001] The present invention relates to an interactive digital television broadcasting system (IDTVS), and to related equipment used in the interactive digital television broadcasting system (IDTVS). Background technique [0002] Such as figure 1 The interactive digital television iDTV system shown is generally known in the art. The interactive digital television iDTV system includes an iDTV provider iTVP sending a downlink digital broadcast stream BS to the broadcast operator BO, wherein the digital broadcast stream BS includes a combination of digital video signals and program logic. Broadcasting operators broadcast digital streams to subscribers either via satellite, cable, terrestrial broadcasting, or via broadband (possibly Internet Protocol IP) Internet systems such as ADSL, VDSL, etc. The user has a digital set-top box that breaks down the broadcast stream into video signals and interaction logic. This interaction logic executes on the set-top box a...
