Launching predefined TV applications based on broadcast app and protocol information

摘要

Apparatus for receiving broadcast stream comprising application portal launching pre-installed application (app) in response to received app ID information identifying predefined app and received protocol information indicating protocol needed to launch app. The apparatus, which may be Digital Video Broadcasting (DVB) receiver, may connect to network location to receive app information. A plurality of broadcast services and different application types may be transmitted in broadcast stream. The app may be video on-demand (VOD) catch-up service for accessing available online content through user controlled electronic programme guide (EPG). The broadcast signal may include minimum version number and app may only be launched if app portal has correct version installed. If app is not identified as predefined on device, it is launched or downloaded from a network location. Application information may be received as Application Information Table (AIT) and identified by comparing known organisation_ID and application_ID values with received signal. The device provides an internet connected television / set-top box (STB) with cross-manufacturer app compatibility that enables broadcasters to ensure that app will always be launched if available because TV/STB uses received app info to determine whether it has required apps installed on its portal.
