Description

[0001] BROADCAST RECEIVING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiving technology, and more particularly, to a broadcast receiving apparatus in a cloud computing environment in which broadcast and broadband channels are integrated.

HbbTV (Hybrid Broadcast Broadband TV) is a general device and system for coordinating existing broadcasters and broadband contents on the Internet to provide a variety of hybrid services to terminal users through Internet-connected televisions or set-top boxes.

The HbbTV receiving apparatus can receive the content data from the broadcasting base station and the VoD (Video On Demand) provider and provide the HbbTV service to the user.

In the conventional HbbTV receiving apparatus, when receiving application and content related data from a VoD provider, it is necessary to execute a plurality of processes such as executing a received application and performing a conversion operation when necessary for outputting a video image of a content to a screen. In the conventional HbbTV receiving apparatus, when a CPU (Central Processing Unit) having a low performance is mounted, work overload may occur in such a process. Since it is more vulnerable to such overloading, the user may not be able to smoothly provide the content service. There is a disadvantage in that content reproduction is limited according to a possible built-in codec.

Korean Patent Laid-Open Publication No. 10-2012-0091089 (Aug. 17, 2012) discloses a digital device that can be connected to a broadcast network and an IP (internet protocol) network. The digital device includes a tuner for receiving broadcast information through a broadcast network, A service manager for detecting information for identifying an Internet service channel capable of receiving an IP signal included in the broadcast information, a service manager for receiving the IP signal through the IP network, And a controller for controlling access to an Internet service channel capable of receiving the IP signal based on the information.

Korean Patent Laid-Open No. 10-2015-0033215 (Apr. 20, 2014) relates to an application program processing technique in a mixed broadcast environment. In a mixed communication environment capable of connecting to a broadcasting network and a high-speed data communication network, The present invention proposes an apparatus and a method for processing an application program so that an auxiliary application program linked to a main application program to be driven by the at least one auxiliary apparatus can be driven by at least one auxiliary apparatus. And instructs the at least one auxiliary device to start the auxiliary application program based on the information about the auxiliary application program included in the additional information.
