Interactive TV system, a related meta data filtering device, a related web service routing device and a related application generating device

摘要

The present invention relates to an Interactive TV system for forwarding data-stream from a head-end device to a client device. The data-stream includes metadata that is related to content of said data stream. The head end device and the client-device are coupled over a communications network. The interactive TV system comprises a Web Service routing part, that is adapted to invoke, based on the meta-data included in the data-stream, a Web-Service that corresponds to the metadata and adapted to subsequently receive a response from the Web-Service based on the metadata as an input of the web service. Furthermore, an application generating part that is adapted to generate based on the response of the web-service, an application for interacting with a user via the client device.
