Description

Apparatus of receiving service signal in Internet Protocol Television

The present invention relates to an Internet protocol television service signal receiving apparatus. In particular, the present invention relates to an Internet protocol television service signal receiving apparatus that can be shared between terminals.

Internet Protocol Television (hereinafter referred to as "IPTV") service converts broadcast data including broadcast content, broadcast information, control information, etc. into IP (Internet Protocol) packets, and then through a general Internet network instead of a conventional broadcast network. It is a service provided to subscribers. In addition, IPTV service is available in a variety of channel configuration and two-way service, this feature is recognized as a great advantage over the conventional over-the-air broadcasting.

In general, in order to provide IPTV services, an IPTV content provider, an IPTV service provider, an IPTV network provider, or an IPTV service subscriber is required.

An IPTV content provider is a subject that creates and supplies various content information provided to subscribers of an IPTV service. In addition, the IPTV service provider bundles the contents provided by various IPTV content providers into a single broadcast program, produces information related thereto, and provides the IPTV service subscribers. In addition, the IPTV network provider operates a network so that contents can be delivered to IPTV service subscribers with a certain level or more of quality, and the IPTV service subscriber uses an IPTV service receiving device to provide the IPTV service provider. It is a subject that consumes various contents.

The IPTV service receiving apparatus is installed in a subscriber's home, and receives an IPTV service signal including IPTV service-related broadcast data and control information delivered from an IPTV service provider and transmits the received IPTV service signal to an external screen display device.

On the other hand, generally, an IPTV service receiving apparatus is composed of hardware, system software (for example, an operating system, a device driver, etc.), an IPTV service middleware, and an IPTV service application program.

The hardware consists of a device control processor, a multimedia processing element, an input / output interface and a network connection interface. System software performs hardware initialization, hardware and software resource control, and interface functions between hardware and system software itself and middleware.

The IPTV service middleware performs a function directly related to an actual IPTV service such as IPTV media stream processing and IPTV broadcast information receiving processing, and its structure and function are determined according to the hardware of the IPTV service receiving device and the service type of the operator. That is, middleware varies depending on the IPTV service provider.

The IPTV service application can be used to control the screen output of the IPTV broadcasting services such as real-time IPTV broadcasting, video on demand (VOD) service, navigation and selection of the service, and electronic program guide (EPG). It also controls the functionality of the app and performs entertainment related applications.

Meanwhile, the IPTV service receiving apparatus may be classified into a wired connection based IPTV service receiving apparatus and a wireless access based IPTV service receiving apparatus according to a type of accessing a subscriber network to receive an IPTV service signal.

An IPTV service receiving device based on a wired connection refers to a fixed device that receives an IPTV service signal through a fixed network access interface such as an 802.3 Ethernet interface.

On the other hand, an IPTV service receiving apparatus based on a wireless access means, for example, a mobile apparatus that receives an IPTV service signal through a mobile network access interface such as 802.16e / m and 802.11 a / b / g / n.

Today's wireless access networks provide users and terminals with convenient mobility, and many subscribers use various multimedia services through wireless access networks. IPTV service is also a representative multimedia service, which has been provided to IPTV service subscribers mainly through fixed IPTV service receivers. However, there is a growing need for providing high quality multimedia services such as IPTV services in mobile environments, and reflecting these requirements, Telecommunication Technology Association (TTA), International Radio Consultative Committee (ITU-T), and Digital Video Broadcasting (DVB) Many standardization organizations such as) are actively researching mobile IPTV services.

In addition, today, each individual has a large variety of terminals at the same time, such as TV, PC, laptop, PDA, mobile phone, etc., the need for sharing multimedia services among these terminals is emerging.

On the other hand, in the conventional IPTV service receiving apparatus that receives the IPTV service signal, the middleware analyzes and processes broadcast data and control information provided by the IPTV service provider, and plays a very important role of substantially providing a broadcast service to subscribers. It is closely related to hardware and system software. In addition, in order to receive a service signal of a specific IPTV service provider, a terminal having middleware provided by the service provider must be used.

However, in order to provide mobility to various terminals while supporting mobility in an environment using contents through an IPTV service receiving apparatus provided by an IPTV service provider, middleware provided by an IPTV service provider may be provided to all terminals that want to receive the IPTV service. To be installed, IPTV service providers have difficulty in producing and managing middleware for all various types of mobile terminals, respectively.

The present invention provides an apparatus for receiving an IPTV service signal that enables an IPTV service subscriber to use his or her own IPTV service while moving freely within a certain range even in a general terminal without an IPTV service middleware.

According to an aspect of the present invention for achieving the above object, an apparatus for receiving a service signal corresponding to the service of the Internet protocol television

A network connection interface unit for receiving the service signal from an internet protocol television service network, a service signal processor for classifying the service signal into broadcast content and broadcast information, and converting the broadcast content and broadcast information into a form usable by an application program; And a terminal connection interface unit configured to transfer the converted broadcast content and broadcast information to a subscriber station of the internet protocol television service.

When the service receiving apparatus moves from the first service area receiving the service signal from the internet protocol television service network to the second service area, the service receiving apparatus reestablishes a connection with the internet protocol television service network and provides the service in the first service area. Receive the service of the received service.

According to an embodiment of the present invention, an IPTV service subscriber may receive an IPTV service even through a general terminal in which middleware necessary for use of the IPTV service is not installed.

In addition, according to an embodiment of the present invention, in a wireless access network that supports mobility, an IPTV service may be used while moving.
