The present invention relates to a data processing apparatus for two-way digital broadcasting for wired and wireless terminals in wired and wireless communication networks (general telephone network, wireless telephone network, Internet network, IP network, cable network, Wibro network, Wimax network, broadcasting network, satellite network). More specifically, the present invention relates to an automatic processing apparatus for two-way digital broadcasting data for wired / wireless digital broadcasting terminals which automatically combines viewer transmission data and broadcasting content data to generate and output metadata for digital broadcasting.

As an example of digital broadcasting, Digital Multimedia Broadcasting (DMB) is a broadcasting service that provides various multimedia signals such as voice and video to digital fixed, portable, and vehicle receivers. • There is a provision method of E. System A follows the European DMB standard (OFDM: Orthogonal Frequency Division Multiplexing) of digital satellite broadcasting and terrestrial DMB, and system Dh is based on terrestrial DMB but adopts a hybrid scheme to accommodate satellite DMB. The code division multiplexing (CDM) scheme is almost identical to the multiple access (CDMA) scheme.

The terrestrial DMB is already allocated to channel 12 of the ultra-high frequency (VHF) band corresponding to 174MHz to 216MHz of television channels 7 to 13. Channel 12 is further divided into three frequency blocks (multiplexers), which can allocate bandwidth of 1.54 Mbps per block. With this bandwidth, one video channel and three audio and data channels can be accommodated. Thus, a bandwidth of one channel (VHF No. 12) of an analog TV can accommodate three video channels and nine audio and data channels. As such, terrestrial DMB can use digital technology to significantly increase frequency efficiency.

Terrestrial DMB that conforms to the European standard 'Eureka-147' technical standard is resistant to the effects of multipath fading, which is a characteristic of the mobile transmission channel, and can be received without deterioration in performance in order to provide various services stably even when moving. A transmission scheme called Orthogonal Frequency Division Mutiplexing (OFDM) is used. In addition, the frequency efficiency is high by applying a compression method called MPEG 4, which has a higher compression efficiency than MPEG 2 of terrestrial digital television.

Satellite DMB, on the other hand, is serviced in the 2.630 to 2.655 kHz band, which is a much higher frequency band than terrestrial waves (UHF). If the terrestrial DMB covers the metropolitan area by launching radio waves from the Gwanaksan transmitting station, the satellite DMB is capable of broadcasting nationwide at once by launching radio waves toward the Korean Peninsula from satellites outside the atmosphere. First of all, the satellite-based service uses Ku-band frequency (13.824) to provide various contents such as news, music videos, sports, movies, dramas, songs, jazz, foreign languages, securities, transportation, and weather. ~ 13.883㎓) to the satellite. The satellite then transmits it to the terrestrial terminal via the S-band (2.630-2.655 GHz) allocated for DMB. If it is not possible to receive satellite signals directly, a terrestrial repeater called 'Gap Filler' relays broadcast signals, allowing the user to use the DMB service anytime and anywhere.

Such digital broadcasting enables broadcast reception in a wired / wireless communication terminal, and a user can watch a high-definition broadcast by using a wired / wireless communication terminal. Accordingly, the increase of broadcasting contents using digital broadcasting is expected, and users can connect to the broadcasting company through various wired / wireless communication methods such as home shopping, live shopping, etc. through various wired / wireless communication methods in real time. You can purchase or join the broadcast.

For such bidirectional digital broadcasting, a conventional digital multimedia data processing apparatus uses a method of manually inserting predetermined metadata into a video signal.

For this reason, the data processing apparatus for bidirectional digital broadcasting of the prior art has a high possibility of a broadcast accident due to an operator's mistake to perform broadcasting in real time because data must be manually inserted or controlled during bidirectional digital broadcasting.

Accordingly, the present invention is to solve the problems of the above-described digital multimedia data processing apparatus for bidirectional digital broadcasting of the related art, and the data for broadcasting content input from an external server for bidirectional digital broadcasting in a wired / wireless communication network. And automatic processing of two-way digital broadcasting data for wired and wireless digital broadcasting terminals for automatically collecting, combining, and converting data transmitted by the viewer and the viewer, and then encoding and transmitting a signal suitable for broadcasting. It is an object to provide a device.

In order to achieve the above object, the apparatus for automatically processing two-way digital broadcasting data for a wired / wireless digital broadcasting terminal according to the present invention includes a viewer transmission data or pre-stored viewer transmission data input from an integrated data server according to an operator's key input data. A data integrating unit configured to receive any one of the server-integrated metadata as an input and perform an integrated operation; And a broadcast signal generator converting the output signal of the data integrator into a broadcast signal and outputting the broadcast signal.

The broadcast signal generation unit converts the integrated data of the data integration unit into metadata for digital broadcasting, and then outputs the metadata to a screen output unit and a broadcast encoder; And a screen output unit configured to output the metadata generated by the metadata generator as an image.

The data integration unit and the key input unit for receiving a key code by the key input of the operator; A server data input unit for receiving and storing viewer transmission data during a real-time broadcast and receiving viewer transmission data and server integration metadata output from an integrated data server having a function of generating different server integration metadata according to broadcast contents; A reservation database for storing previously transmitted viewer transmission data and server integrated metadata to be integrated into the data for recording broadcasting; And a reservation data input unit for receiving the reservation database stored data as an input.

The metadata generating unit may further include an output interface unit for outputting the generated metadata to a broadcast encoder.

When the bidirectional digital broadcasting data automatic processing apparatus of the present invention is provided, the automatic transmission of the viewer transmission data can be easily transmitted to the broadcasting encoder equipment by automatically converting the viewer transmission data into the broadcasting data.

That is, the present invention controls and integrates the viewer transmission data to be entered into the interactive digital broadcasting according to the key code input by the operator through the key input unit, converts it into digital broadcasting metadata, and automatically outputs it to the broadcasting encoder. By generating and outputting a broadcast signal integrating the digital broadcasting content data and the viewer transmission data converted into meta data, the viewer transmission data in the bidirectional digital broadcasting can be automatically integrated into the broadcasting content data for transmission.

In this case, the above-mentioned automatic processing apparatus for bidirectional digital broadcasting data according to the present invention is configured to perform data processing by selecting any one of real time (live broadcasting) or non real time (recording broadcasting) with respect to viewer transmission data.

Hereinafter, the present application will be described in more detail with reference to the accompanying drawings.

A reservation database 12c for storing the viewer data and server integrated metadata; A reservation data input unit 12b for outputting data of the reservation database 12c to the data integration unit 13; In the case of real-time broadcasting (live broadcasting) data processing, the operator's key code, the viewer transmission data input from the server data input unit 12a, and server integrated metadata are integrated and processed, and the non-real-time broadcasting (recording broadcasting) data processing is performed. In the case of the digital data broadcasting unit 13 and the integrated data output from the data integration unit 13 and the integrated data processing unit 13 and the server-integrated meta data is output through the reservation data input unit 12b Metadata generator 14 and metadata generator 14 for outputting to screen encoder 15 after being converted to metadata and outputting to broadcast encoder 17 through output interface 16 when it is normally processed. It is configured to include a screen output unit 15 for outputting the generated metadata in the image.

Here, the metadata generator 14, the screen output unit 15, and the output interface unit 16 become the broadcast signal generator of the present invention.

FIG. 2 is a flowchart illustrating an operation process of the data processing apparatus of the present invention. Referring to FIGS. 1 and 2, the operation process of the data processing apparatus of the present invention is as follows.

First, in the configuration of FIG. 1, the key input unit 11 generates a key code signal input by an operator to control and insert data, and outputs the key code signal to the data integrating unit 13. To this end, the key input unit 11 may be configured in the form of a dedicated input console for inputting a control command for processing broadcast data.

The server data input unit 12a receives and stores the viewer transmission data transmitted by the viewer through the wired / wireless communication network using a wired / wireless communication terminal during a real-time broadcasting, and the integrated data server 1 for storing server integrated metadata. The viewer transmission data and the server integrated metadata are received from the viewer and output to the data integration unit 13.

The reservation database 12c receives and stores viewer transmission data during recording for recording broadcasting, and stores server integrated metadata. The reservation data input unit 12b stores viewer transmission data stored in the reservation database 12c during recording broadcasting output. And outputting the server integration data to the data integration unit 13.

In FIGS. 1 and 2, the data integrating unit 13 receives a key code signal for controlling and inserting data through the key input unit 11, and transmits the viewer from the server data input unit 12a in the case of real time broadcasting (live broadcasting). It receives data and server integrated metadata and integrates and outputs the data according to the key code signal. In the case of recording broadcasting, a key code signal for controlling and inserting data is received through the key input unit 11 and stored in the reservation database 12c through the reservation data input unit 12b. The data is input and output in combination with the key code signal (S1).

The integrated data output in step S1 is input to the metadata generating unit 14, and the metadata generating unit 14 converts the data output from the data integrating unit 13 into metadata for digital broadcasting (S2). .

If the verification of the process S4 fails to verify the data or an error command is input by the operator, the process moves to process S2 and the process proceeds to process S2 which converts the viewer transmission data into metadata again under the control of the operator's input keycode. The process is performed again (S5).

On the contrary, when the data verification is successful as a result of the determination in S4 and the error message is not input by the operator, the metadata generating unit 14 of the data processing apparatus 10 converts the signal into a signal suitable for the broadcast encoder 17. The metadata is output to the broadcasting encoder 17 of the broadcasting station through the interface 16. The broadcasting encoder integrates and encodes the broadcasting content data and the digital broadcasting metadata of the viewer transmission data output from the data processing apparatus 10 of the present invention.
