Description

IPTV customer system that provides Internet telephony service and method thereof {IPTV CLIENT SYSTEM OF PROVIDING INTERNET PHONE AND METHOD THEREOF}

The present invention relates to an IPTV service technology, and more particularly, to an IPTV customer system and a method for providing a differentiated service to a customer by providing an Internet telephone service.

Along with the rapid development of Internet technology, the Internet Protocol TeleVision (IPTV) service has recently been developed and widely commercialized.

The IPTV service is a service for providing television broadcast programs, video, audio, text, data, and the like through an IP-based network, and includes video on demand (VOD), T-commerce, entertainment, banking, information, TV portals, and multichannel broadcasting services. It refers to a two-way TV service that provides multimedia content such as packet through a TV terminal connected to a digital set-top box through high-speed Internet, such as asymmetric digital subscriber line (ADSL) and Fiber to the Home (FTTH).

The performance and functions of the digital set-top box are being further improved to provide various multimedia services. Accordingly, manufacturers or service providers are making various efforts to provide differentiated services to customers through the high-performance digital set-top box.

On the other hand, as the value-added services (VAS) provided by the set-top box is diversified and newly added, the set-top box developer prepares an implementation application in the set-top box every time a new service is added. Since it should be built in, there is a problem that the technical development burden on the set-top box is increased.

In addition, there is a problem that the manufacturing cost of the set-top box increases as the number of driving applications embedded in the set-top box to implement a variety of services.

In addition, as the development and change cycles of supplementary services provided by IPTV services are shortened, whenever a supplementary service (e.g., an Internet telephony service) is newly added, the set-top box that has been previously distributed is recovered and a set-top box supporting the subscriber is provided. There is also the difficulty of a new release.

Therefore, there is a need for a scheme for allowing subscribers to easily use additional services added in the IPTV service without replacing the existing set-top box.

It is an object of the present invention to provide an IPTV customer system and a method thereof for providing an Internet telephony service for providing an Internet telephony service in addition to an IPTV service to a customer receiving an IPTV service through a high-performance digital set-top box. .

It is another object of the present invention to provide an IPTV customer system and a method for providing an Internet telephony service through which a video call service can be provided through a television broadcast receiver and a small camera connected to a set-top box.

In addition, another object of the present invention is to enable subscribers to easily use additional services without replacing the entire set-top box when additional services such as Internet telephony services are newly added in the IPTV service, and to reduce the burden of developing the set-top box. .

An IPTV customer system for providing an Internet telephony service of the present invention for achieving the above object comprises: a wireless access handy terminal for performing information input and voice input / output; A radio access station for performing radio communication with the radio access handy terminal; A soft phone client that connects to a soft switch server via a network according to information provided from the wireless access handy terminal through the wireless access station to perform dialing or incoming calls, and establishes a call path with the wireless access handy terminal and the other party. It is equipped with a module, characterized in that it comprises a set-top box that provides IPTV services.

The present invention has the advantage of providing differentiated services to customers by enabling Internet telephony services in addition to IPTV services to customers receiving IPTV services through a high-performance digital set-top box.

In addition, another object of the present invention is to provide a video call service through a television broadcast receiver and a small camera connected to the set-top box, there is an advantage that can provide a differentiated service to customers.

In addition, the present invention provides a wireless access station that can be connected to the set-top box via a USB port, so that when an additional service is added in the IPTV service, a wireless access station equipped with an application supporting a new additional service is connected to the existing set-top box. All you need to do is make your new supplementary service available to your subscribers. Therefore, the service provider side can reduce the development burden of the set-top box, and subscribers can use the newly added value-added services quickly and easily.

Internet telephony service is a technology for transmitting voice signals through the Internet. Unlike conventional circuit-switched telephones, Internet telephony services transmit voice in the form of packets through an IP (Internet Protocol) network, which is the basis of the Internet. Such an internet telephony service can increase network efficiency, provide various intelligent network services linked to the Internet, and have a low cost for long distance calls such as long distance and international calls.

The present invention provides a differentiated service to a customer by additionally providing a voice over internet protocol (VoIP) service to a customer who receives an IPTV service through a high-performance digital set-top box.
