The present invention relates to a method and apparatus for providing integrated services of communication and broadcasting, and more particularly, to provide a stable real-time service by integrating a conventional real-time broadcasting service and an IP-based broadcasting service, and at the same time, based on IP. To provide a variety of additional services.

Real-time broadcasting can be divided into cable broadcasting, satellite broadcasting, and airwave broadcasting.

Cable broadcasting is a method of delivering program contents received from a broadcaster and a program provider through a coaxial cable wired to a subscriber's home. In the case of digital cable broadcasting, a set-top box for cable broadcasting is required for processing a broadcast signal, and the channel can be viewed through this.

Satellite broadcasting decodes the satellite broadcast signal received through the satellite antenna through a satellite broadcast set-top box, and the airwaves can receive a radio wave containing the broadcast signal transmitted by the broadcaster through the aerial wave antenna to view the channel.

However, the real-time broadcast described above is unidirectional communication and is transmitted from the transmitting end to the receiving end of the user. Since this process is performed in only one direction, there is a problem that the user can only receive a uniform service provided in this communication method.

As a bidirectional communication technology for improving such a problem, there is a broadcasting technology called IP-TV. IP is a representative protocol used in the Internet, and is mainly used for data transmission, and is currently used for real-time communication service. The video service is also provided in real time using the IP-based communication network, and IP-TV is a broadcast service using the same. In the IP-based broadcast service, the conventional broadcast service is unidirectional, whereas the viewer can control and select the functions and contents of the broadcast in both directions. Due to the characteristics of the IP-based network, viewers can receive various customized services. Representative services include time-shifted broadcasting that provides functions such as stop, rewind, play, and fast playback, and when a user applies for a scheduled recording of a specific program or time, the server saves the contents and provides them at the desired time. There are services such as network-based reservation recording. However, since IP-TV technology utilizes an IP-based network, the traffic of the network must be considered.

That is, unidirectional real-time broadcasts such as cable broadcasting, satellite broadcasting, and over-the-air broadcasting transmit broadcasting contents using broadcasting method, and excessive broadcasting when transmitting all existing real-time broadcasting in IP-TV technology format for two-way service As a result, there may be a problem in that the technical implementation is not easy because it may cause problems of quality of service (QoS) and stability of the network.

In addition, PVR (Personal Video Recorder) is a technology that can provide a service similar to the above service to the viewer. The PVR stores broadcast content according to a user's intention by using a kind of set-top box having a storage medium capable of storing broadcast content.

However, in the case of PVR, a storage device is required in the PVR itself, and these storage devices are mainly expensive equipment. PVR has a problem that the price is expensive due to the expensive storage device. In addition, there is a problem in that a storage device must be purchased more when the storage capacity is additionally changed, and a storage capacity is limited due to a limitation of the storage capacity.

In addition, the PVR uses a single receive tuner. Due to the unity of the reception tuner, there is a problem in that recording on a plurality of channels is impossible at the same time.

An object of the present invention for solving the above problems is to provide a real-time broadcast service by receiving a broadcast signal of an existing broadcaster and at the same time to provide an IP network-based bidirectional broadcast supplementary service at the request of a user.

In order to achieve the above object, the integrated set-top box for providing integrated communication and broadcasting services according to the present invention includes a real-time broadcast processing unit for receiving a broadcast signal from a broadcaster, and an IP broadcast signal in the form of a broadcast supplementary service from an IP-based network. An IP signal processing unit, an operation panel for receiving a command for selecting a service from a user, and an output selection unit for selecting output paths of the real-time broadcasting processing unit and the IP signal processing unit by a command received through the operation panel. do.

In accordance with one aspect of the present invention, there is provided a method of providing integrated service for communication and broadcasting, the method including receiving a broadcast signal from a broadcaster and outputting the same to a user, and receiving a service selection based on an IP-based additional service request from the user. A second process, a third process of requesting transmission of broadcast content for a corresponding supplementary service to an IP based service system according to the input service selection, and a broadcast content for the supplementary service by replacing the broadcast signal of the first process And a fourth process of outputting to the user.

The IP-based service system 200 provides a service such as time-shifted broadcast or reservation recording according to a user's request by using the broadcast content received from the broadcast headend 100. The IP-based service system 200 transmits the service to the user who requested the service by the unicast method.

In addition, the IP-based service system 200 may have a respective server in charge of services such as time-shifted broadcast and scheduled recording, because services such as time-shifted broadcast and scheduled recording require different performance. This is because time-shifted broadcasting must store broadcasts in real time and provide immediate broadcast transmissions upon service requests in order to provide services according to user demands. On the other hand, in case of reserved recording, broadcasting storage capacity is more important than time required for providing a service. The scheduled recording service requires extensive storage capability such as simultaneous recording of multiple channels and recording by broadcasting contents according to user's request.

The IP-based network 300 is, for example, an IP-based network capable of transmitting data such as Ethernet, Local Area Network, Wide Area Network, Mobile Communication Network, Wireless Network, or Telephone Network. .
