Description

TECHNICAL FIELD [0001] The present invention relates to a HD / UHD multi-channel video data routing switch system for a studio,

The present invention relates to a HD / UHD multi-channel video data routing switch system for a studio, and more particularly, to a multi-channel HD / UHD multi-channel video data routing system for a studio, And an HD / UHD multi-channel video data routing switch system for a studio, which performs switching at the same time so that at least one video channel is output from each port of an output terminal.

Recently, with the completion of High Efficiency Video Coding (HEVC), a video compression standard that supports 4K and 8K UHD class resolutions, interest in devices such as routers and switchers for UHD class video processing is increasing. This is because the UHD-class image needs to be distributed or combined and the studio needs UHD-class image routing or switching.

A video switch system (also referred to as a switcher) is a device for selecting and outputting one of a plurality of different images. A mixer synthesizes or edits video signals for a plurality of input channels, .

Often, by using the image switch system or the image mixer, it is possible to synthesize a corporate logo or a subtitle on an image of a selected channel, to edit the special effect, and to output it together with the corresponding image. In addition, the image matrix switch system differs from a simple image switch system in that an image input through a plurality of input channels is matched to and distributed to a plurality of output channels, similar to the image switch system.

Therefore, in the case of the video switch system, it is not possible to individually output various editing images and special effects according to each output channel because only a single output channel can be selected, and the image matrix switcher can perform multiple output, 1: 1 " In this case, the screen may be distorted when the screen is switched, and a monitoring channel for the input screen must be separately provided to directly check the input screen. In particular, the demand for outputting multiple video signals according to the input of multiple video signals is increasing. However, in the conventional video matrix, unlike the switch system, there is a phenomenon of screen splashing or it is not easy to edit and output video effects in real time Respectively.

In addition, since there is no matrix switcher having multi-channel routing function of HD / UHD video, a system and a switch system for performing routing are separately provided. In addition, despite the complexity of such a complex system, it is difficult to achieve desired switching results for HD / UHD images. Furthermore, there is no system for supporting how to mix and output each image when a plurality of images are to be output through one channel after performing routing and switching.

FIG. 1 is a block diagram of a multi-channel video data routing switch system for a studio according to an embodiment of the present invention, and is a conceptual diagram for providing a service by interfacing the system with a peripheral device.

1, the multi-channel video data routing switch system for a studio according to the present invention includes an input unit 100, a preprocessing unit 200, a routing switch unit 300, an output unit 400, and a system control unit 500 ).

As shown in FIG. 1, the input unit 100 receives an image signal of an external camera directly or receives an image signal from an external camera or a server through a wired / wireless network. Also, the input unit 100 is not limited to receiving a single video signal and receives at least one video signal from the outside. Therefore, the input unit 100 may further include the wired / wireless communication interface and the camera interface to extract frame data from an input video signal and transmit the frame data to the preprocessor's frame memory.

The preprocessing unit 200 synchronizes frames with respect to image data for a plurality of input channels received from the input unit 100 and outputs the image data to the image input unit 100 in response to a user's request. And generates and applies effects using a linear key, a linear key, a downstream key, an upstream key, a luminance key, a time code, a scale up, a scale down, deinterlacing, morphing, texture mapping, blending, watermarking or a combination thereof .

The routing switch unit 300 performs routing and switching operations according to a routing table designated by the user, and when a plurality of video data channels are routed through a specific output channel, And mixes the video data of the video data according to the mixing pattern requested by the user and outputs the mixed data to the output unit. The routing switch unit 300 is controlled by an external user through a user interface 550, a wired / wireless communication interface 560, or a control console 570.

The output unit 400 outputs switched image data from the routing switch 300 and converts the image data into a format for storing the image data on a display monitor or a storage medium. Depending on the output format, it converts to a display format such as VGA, DVI, HDMI and a storage format via a network interface. The apparatus may further include a D / A conversion function for performing video encoding according to a format of an image to be output and converting the digital signal to analog in order to transmit the encoded digital video signal to the outside. Also, the video signal transmitted from the output unit 400 may be directly transmitted to at least one monitor or may be output to an external server or an external monitor through a wired / wireless network.

2 is a configuration diagram of a preprocessing unit and a routing switch unit in a multi-channel video data routing switch system for a studio according to an embodiment of the present invention.

2, the preprocessing unit 200 includes a frame buffer 210, a frame synchronization unit 220, a frame reference providing unit 230, an effect generating unit 240, and an effect controlling unit 250 .

The frame buffer 210 includes a memory for receiving image data received through the input unit 100 and storing the received image data. The memory may be configured separately for each input channel, or may be configured to use a memory of a large size divided for each input channel. If a large memory is divided, the number of addressing bits may be large, and there may be a delay in addressing. When frame buffering is performed using an individual memory for each input channel, a plurality of individual memories must be used. . In the present invention, regardless of the method used, the image data transmitted through the input channel is an HD / UHD resolution image, and a storage space for storing at least one frame is required for each channel. The frame buffer performs buffering by sequentially writing image data transmitted through an input channel to a storage space of a memory. The operation to write to the memory is to write the image data to the memory by generating the sequential address.

Next, the frame synchronization unit 220 performs an operation of reading image data stored in each of the frame buffers 210 based on the frame reference signal provided by the frame reference providing unit 230 at the same time. That is, if the image data is stored in each individual frame buffer from the start position of the frame, the frame synchronization unit reads the image data from the start address of all the frame buffers. If the image data is not aligned in the frame buffer If it is stored from an arbitrary position of the frame image, the frame synchronization unit may recognize the start of the corresponding frame image data and then read the corresponding frame image to perform the framing synchronization. It is the frame synchronization unit that performs this control.

The frame reference providing unit 230 provides the frame buffer 210 or the frame synchronizing unit 220 with a reference signal for storing frame image data in the frame buffer 210, And provides a read reference timing, thereby providing a reference signal so that the frame buffer and the frame synchronization unit perform frame synchronization. In this process, for example, the frame reference signal of the image data for each input channel is input and the reference signal of the other input channel is matched to the frame reference signal of the specific input channel, so that the frame image data is written to the frame memory, By reading the data, the frame synchronization is performed.

By adding and adding effects to the synchronized frame image data, it is possible to insert an effect on each input channel. The effect generation unit 240 receives the synchronized image data from the frame synchronization unit 220 and generates and applies an effect to the corresponding image data.

The effect control unit 250 controls which input channel is to be inserted with an effect. In other words, the effect generation unit 240 may generate the subtitle, the caption, the computer graphic, the color conversion, the preview, the overlay, the chroma key, the linear key, the downstream key, the upstream key, the luminance key, the time code, , Morphing, texture mapping, blending, watermarking, or a combination thereof, and inserts the generated effect for each input channel under the control of the effect control unit. Here, the effect to be inserted may be generated and stored in advance, and a specific effect may be inserted into each input channel according to the selection of the effect control section. Alternatively, a certain effect may be generated and inserted in real time. Control.

Next, there is a routing switch 310 for performing switching according to the routing table provided by the system control unit 500 for the input channel on which the preprocess has been performed. The routing switch includes routing the video data of the input channel to the output channel By performing switching at the same time, routing can be routed to any output channel for multiple input channels. When the input channel is switched to the designated channel (routing) and the input channel is mapped to the output channel, a plurality of input channels can be mapped to one output channel. At this time, if a plurality of input channels are accommodated in the corresponding output channel and image data can be outputted at a speed or a bandwidth of a plurality of times, the output speed of the output channel can be increased and output.

However, if the video data output speed of the output channel is equal to the input speed of the input channel, or the bandwidth for outputting a plurality of input channels to the output channel is not secured, the image data of the input channel must be divided and mapped to the output channel. The role of the mixing unit 320 is to perform such a role.

Hereinafter, the routing switch unit 300 including the routing switch 310 and the mixing unit 320 and the system control unit 500 will be described in detail.

3 is a configuration diagram of a routing switch unit including a routing switch and a mixing unit in a multi-channel video data routing switch system for a studio according to an exemplary embodiment of the present invention.

As shown in FIG. 3, the routing switch unit 300 includes a routing switch 310 and a mixing unit 320.

In the routing switch 310, since only the routing path is set even if the input channel connected to the input channel port is branched into a plurality of routing paths, there is no problem in processing the image data. However, in the case of the output channel port, since the progress direction of the data is output to the output unit, a bottleneck occurs in outputting a plurality of pieces of image data if they are collected. A method for solving such a bottleneck is to secure bandwidth so as to accommodate n image data of the input channel. However, securing such a bandwidth may not be possible because it requires real-time high-speed data processing.

Therefore, in the present invention, it is desired to support the mixing of image data so that a plurality of input channel image data can be outputted temporally or spatially.

The mixing may be configured to spatially divide the input image data into n image segments according to a specific division pattern (or a mixing pattern), reconstruct the image data frame into one image data frame, and output the image data frame to the output channel. Also, if the spatial resolution of the output image data is not desired to be lost, image data for a plurality of input channels may be accommodated by reducing the frame rate in time. In this case, the frame is configured to transmit image data for a plurality of channels alternately. In addition to outputting image data for a plurality of channels through spatial and temporal segmentation, there may be a method of lowering SNR (Signal to Noise Ratio) for image data of each channel. That is, the image data of each input channel is simplified by removing the redundancy of data lossless or lossy in time or space temporally or spatially with respect to a plurality of input channels to be output to the output channel, It is possible to reconstruct and output the data. Of course, it is also possible to perform mixing by temporal and spatial division according to the programmed specific sequence. That is, in the case of spatially dividing and transmitting, information on a basic image of a specific input channel is transmitted. In case of dividing and transmitting in time, the entire image data is transmitted to each input channel, It is possible to mix the high-resolution image data periodically input with the data and complement the low-resolution image data with the high-resolution image data.

The routing switch 310 performs a function of matching the physical routing paths with each other using the address values of the input channel port and the output channel port stored in the routing table 540 do.

When a plurality of pieces of image data are routed to the output channel port at an output channel port routed by the routing switch 310, the mixing unit 320 may extract a predetermined format according to the number of video routed to a specific output channel. And mixes them temporally, mixes them, or mixes them in accordance with a predetermined mixing program to perform mixing. In addition to outputting image data for a plurality of channels through spatial and temporal segmentation, there may be a method of transmitting SNR of image data of each channel by lowering SNR.

The output channel port is assigned an address in the routing table, and is connected to the mixing unit 320 and transmits the mixed video signal processed by the mixing unit to the outside of the routing switch unit 300. Also, the output channel can output m video data without restriction on the number of received n video signals and resolution.
