HbbTV goes Cloud: Decoupling Application Signaling and Application Execution in Hybrid TV

The cloud-based execution of the User Interface has already begun to disrupt the TV domain. Indeed, in European Hybrid TV Standard - Hybrid Broadcast Broadband (HbbTV) - the signaling of applications is terminated by special libraries on the client. Therefore, the cloud-based UI execution does directly affect the HbbTV. This work presents an architecture that enables the shift of HbbTV functionality into the Cloud. This is based on the decoupling of HbbTV application signaling and application execution on the client side. The shift is executed by defining new interfaces for HbbTV-to-cloud and cloud-to-device. This work describes possible approaches for such architectures, relevant open issues and corresponding challenges.
