The present invention not only receives digital broadcasts currently provided using the UHD module, but also supports simultaneous reception of multiple channels, thereby enabling simultaneous viewing or real-time storage of different channels, and in addition to broadcasting viewing, a monitoring system is provided. The present invention proposes a digital broadcast reception system using a UHD module that can provide a video with broadcast viewing.

1 is a diagram illustrating a UHD module 100 according to the present invention, an interface unit 110 for inputting and outputting raw data for an HD image, and raw data for each HD image received from the interface unit 110. After receiving the pre-processing unit 120 for generating the original image data by arranging the raw data according to the UHD image format, and receiving the original image data pre-processed through the pre-processing unit 120 according to a preset file format An encoder unit 140 which controls whether the interleaved, non-interleaved, screen size is considered or, if necessary, compresses it into a predetermined video format (MPEG, AVI, MPEG-2 TS, etc.) to generate a UHD image; It may further include a high speed storage medium 130 for storing the original image data passed through the preprocessor 120.

In this case, the high speed storage medium 130 may store the original image data in real time, including an E-IDE hard disk or a solid state disk (SSD).

Therefore, the UHD module 100 as described above may generate and store four HD images as 4K UHD images based on 4K UHD.

2 is a diagram illustrating a configuration of a broadcast system using the UHD module 100 as described above, in which an output terminal of a broadcast channel receiver 200 for receiving a broadcast receives an HD image configured in the interface unit 110. It can be connected to the input channel for.

The broadcast channel receiving unit 200 may include a communication unit, a tuner unit, a demodulator, an output unit, and a processor. The communication unit receives a wireless or wired broadcast signal, and the tuner unit is based on the broadcast signal received by the communication unit. By performing baseband processing for a specific channel to receive a broadcast signal for the digital HD broadcast image through the antenna unit, the demodulator performs digital demodulation from the broadcast signal received from the tuner unit for the broadcast image Streaming data may be delivered to the processing unit.

In this case, the communication unit may be connected to a wired cable network such as a hybrid fiber coax (HFC) to receive a wired broadcast channel.

Meanwhile, the processing unit compresses and restores the streaming data received from the demodulator in real time as needed, and transmits the HD image data to the output unit, and the streaming data that does not require compression restoration is transmitted to the output unit in real time.

The processor may receive an input for a specific channel from the user interface 300, and control the tuner based on the user input of the user interface 300 to change the broadcast reception band.

Thereafter, the output unit may serially transmit the HD image data received through the processing unit as a serial signal for high speed transmission to the interface unit 110 of the UHD module 100. In this case, the output unit is configured in the form of DVB-ASI (Digital Video Broadcasting-Asynchronous Serial Interface) to transmit the ASI signal, ASI is an embodiment of the serial transmission interface, it is configured to replace the other interface supporting the serial transmission You may.

In general, the output unit supports two output terminals for outputting two channels, and accordingly, the broadcast channel receiver 200 simultaneously receives two channels of HD broadcast received through a multi-band and through the output unit. It may be input to the interface unit 110 of the UHD module 100.

Therefore, since the interface unit 110 of the UHD module supports four HD video inputs based on 4K UHD, as shown in FIG. 3, four interface channels are connected to two different broadcast channel receivers 200. Can be received. However, the 8K UHD module or more advanced UHD module 100 having more processing power can be connected to two or more broadcast channel receivers 200, which can further increase the number of HD broadcast images that can be accommodated. The connection method is not different from the above.

Meanwhile, the preprocessing unit 120 of the UHD module 100 receives HD image data of HD broadcast images of a plurality of different channels from the interface unit 110, preprocesses the HD image data into the original image data, and then performs a high speed interface. Through the fast storage medium 130 may be stored in real time. That is, the UHD module 100 receives and processes HD image data transmitted in units of frames for the broadcast image reconstructed through the broadcast channel receiver 200 instead of processing the original raw data.

In addition, the encoder unit 140 may receive original image data of the broadcast image of the broadcast channel to be output through the interface unit 110 from the preprocessor 120 and output the real time to a predetermined area in real time. The original image data may be arranged from the storage medium 130 according to the UHD screen configuration to be configured in a selected area of the UHD screen configuration and output to the external monitor 400 through the interface unit 110.

To this end, as shown in FIG. 2, the user interface unit 300 may be further configured, and the user interface unit 300 receives a user input and a control signal for a channel to be extracted by the encoder unit 140. May be transmitted to the encoder unit 140. The encoder unit 140 may extract original image data of a broadcasting channel corresponding to the control signal, generate a UHD image, and output the same through the interface unit 110. Alternatively, when the viewpoint information is input through the user interface unit 300, the original original image data stored in the fast storage medium 130 is extracted to generate a UHD image, and then the external monitor through the interface unit 110. Output to 400.

On the other hand, since the original image data is stored in units of frames rather than having an MPEG structure according to a codec, positional movement of the original image data is possible in units of frames for a broadcast image, and analog operation such as a jog shuttle can be supported. Thus, the user interface 300 can be configured in parallel with digital and analog.

In this case, the original image data as described above is transmitted or stored in a UHD frame unit except for the compression process in the UHD module, and is automatically synchronized between a plurality of original image data constituting one UHD screen.

That is, the preprocessing unit 120 can perform synchronization of desired views between different channels on the UHD screen with only a simple data arrangement without additional processing, and supports storage of original image data in real time frame units. The encoder unit 140 can easily extract a UHD frame corresponding to a desired time point from the high-speed storage medium 130, and then output the frame continuously as a UHD image. By extracting the original image data composed of the original image data in one UHD screen, it can accurately correspond to the user's input.

Accordingly, the encoder unit 140 may provide an accurate frame corresponding to a desired time point input through the user interface unit 300, and the user interface unit 300 may be configured by the analog support method. In addition, while watching a broadcast image for one channel at a desired time point, it is possible to record an image broadcasted by another channel at the same time point.

In addition, the encoder unit 140 extracts original image data of a past time point of the broadcast currently being viewed based on a user input of the user interface unit 300 while viewing and arranges the original image data in a partial region of the UHD screen configuration. It may be output through the unit 110. That is, it is possible to support a function that can simultaneously check the current point in time and the past point of view on a single UHD screen.

In addition, the user interface 300 transmits a control signal for channel selection to the broadcast channel receiver 200 in response to a selection channel according to a user input, and the broadcast channel receiver 200 based on the control signal. By varying the band of the tuner unit, it is possible to receive a signal of a broadcast channel corresponding to a user input.

For example, when a viewer views one of two different channels through the user interface unit 300 and selects the other one for recording, the encoder unit 140 selects the user interface unit 300 as described above. After receiving the original image data converted according to the UHD format for the broadcasting channel according to the control signal through the pre-processing unit 120, and outputs through the interface unit 110 to a partial region or the entire region of the UHD screen. The HD image data for the remaining recording channels may be stored in real time to the high speed storage medium 130 immediately after the preprocessing unit 120 converts the original image data according to the UHD format.

In addition, when the viewer simultaneously watches and records the same channel through the user interface 300, the broadcast channel receiver 200 transmits HD image data of the same channel through a plurality of output terminals. The preprocessing unit 120 may convert the HD image data into original image data, transmit one of the same channels to the encoder unit 140, and store the other one in the high speed storage medium 130 to perform recording.

Through the above-described bar, the encoder unit 140 according to the present invention may simultaneously output and store up to four channels of HD broadcast video on an external display, and may simultaneously view and store the same channel.

Meanwhile, when broadcasting of a specific channel supports UHD, two broadcast channel receivers 200 are connected to the interface unit 110, and the plurality of broadcast channel receivers 200 are users of the user interface unit 300. On the basis of the input, all the tuners are synchronized to the band corresponding to the specific channel. Accordingly, four output terminals of the plurality of broadcast channel receivers 200 output HD image data for UHD broadcasting of the specific channel.

Accordingly, the preprocessing unit 120 outputs the original image data generated by arranging the plurality of HD image data to correspond to the UHD frame configuration to the encoder unit 140, and the encoder unit 140 One UHD image may be generated by splitting and receiving a UHD screen of a specific channel supporting UHD broadcasting into four HD screens and arranging them according to a predetermined arrangement. In this case, the preprocessing unit 120 may perform interpolation between the respective HD image data constituting the UHD image, and may finish the boundary line between the HD images, and may also perform color correction. In addition, the encoder 140 may code the generated UHD image and output the encoded UHD image to the external display 400 through the interface unit 110.

In addition, according to the input of the user interface unit 300, the encoder unit 140 simultaneously extracts different original image data from the preprocessor 120 or the high-speed storage medium 130 to display each channel in the UHD image. The area in which the broadcast is to be configured may be determined. Accordingly, the HD broadcast video for a plurality of different channels may be simultaneously output on one UHD screen. For example, in the case of the 4K UHD standard, up to 4 different channels of HD broadcast images may be simultaneously output.

On the other hand, the present invention may be connected to the camera 500 for capturing HD video in addition to broadcast reception to support monitoring.

4, a part of the input channel of the interface unit 110 is connected to an output terminal of the broadcast channel receiving unit 200, and a part of the input channel of the interface unit 110 is connected to the HD image supporting camera 500. HD video data of the broadcast video and the captured video may be input through the input channel.

Accordingly, the preprocessing unit 120 converts the HD image data into original image data according to the UHD format and outputs the original image data to the encoder unit 140, and the encoder unit 140 displays the UHD screen among the original image data. After determining the image to be output, simultaneously output both the broadcast image and the captured image on the UHD screen as shown in FIG. 5 (a), or all the input channels of the interface unit 110 as shown in FIG. 5 (b). By connecting only the broadcast channel receiver 200 or only a camera to the broadcast channel or one object arranged to configure a screen divided into four HD video for one UHD video through the interface unit 110 You can print

In addition, the preprocessing unit 120 converts the HD image data not selected by the user interface unit 300 into the original image data on the high speed storage medium 130, and stores the HD image data in real time. The high speed storage medium 130 may be stored.

Through this, the digital broadcast receiving system using the UHD module according to the present invention is not only supports multi-channel broadcast reception but also provides multi-purpose broadcasting and video recording or surveillance images for buildings or specific places where monitoring is required.
