Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals are used for the same components in the drawings, and duplicate descriptions thereof are omitted.

1 is a flowchart schematically illustrating a process of a vertical mode streaming method according to an embodiment of the present invention, and FIGS. 2a and 2b are pictures showing the vertical mode streaming method of FIG. 1 applied to a smartphone. . 3a to 3d are photographs and plan views for explaining problems caused by the application of a general vertical mode streaming method in a broadcast camera, and FIGS. 4a and 4b are a photographing method and its corresponding These are the pictures that show the video.

Referring to FIG. 1 , in the vertical mode streaming method according to the present embodiment, each of at least two broadcasting cameras is rotated clockwise or counterclockwise by 90° to photograph an object in a vertical direction (S110). Here, a camera for broadcasting (refer to 100 in FIG. 3A or 100R in FIG. 4A) may mean a general camera used by a broadcasting station. The cameras 100 and 100R for broadcasting may be, for example, high definition (HD) cameras. Depending on the embodiment, the broadcasting cameras 100 and 100R may be replaced with a freely movable HD camcorder. Normally, the broadcasting cameras 100 and 100R may photograph an object so that the horizontal length is long. For example, the cameras 100 and 100R for broadcasting may photograph an object in a horizontal:vertical aspect ratio of 16:9. Here, horizontal may mean the x-axis and vertical may mean the y-axis. Therefore, photographing an object so that the horizontal length is long means that the x-axis of the image is photographed long, and photographing the subject so that the vertical length is long means that the y-axis of the image is long. there is. In the following description, for convenience, 'photographing an object in a long horizontal direction' is referred to as 'photographing in a horizontal mode', and 'photographing an object in a vertical direction' is referred to as 'photographing in a vertical mode'. Meanwhile, with respect to the step of photographing in portrait mode (S110), it will be described in more detail in the description of FIGS. 4A and 4B below.

Next, the captured images are rotated 90° clockwise or counterclockwise (S120). For example, when the object is photographed by rotating it clockwise by 90°, the captured image is rotated by 90° counterclockwise, and when the object is photographed by rotating it by 90° counterclockwise, the captured image is captured. Rotate 90° clockwise. In this way, rotating the captured images to their original positions may be for streaming in the next step. Also, rotation of the captured image may be performed through image processing software. More specifically, when shooting in portrait mode, the image processing software stores the captured image, that is, the image captured vertically, with a fixed aspect ratio, rotates the image of the fixed aspect ratio by 90°, , the rotated image can be encoded with additional information and formatted into a bitstream.

Thereafter, images are streamed in portrait mode (S130). Here, streaming may refer to a technology of reproducing audio, video, animation, etc. in real time without separately storing them on the Internet. For example, in the portrait mode streaming method of the present embodiment, it may mean playing a previously captured video on a smartphone in portrait mode. More specifically, a bitstream of an image previously captured in portrait mode may be transmitted to an image reproducing apparatus through a network. In addition, the image reproducing apparatus may play an image by decoding the received bitstream. Here, the video reproducing device may be a smart phone, and the video may be directly displayed in a portrait mode according to the aspect ratio of the smart phone.

Referring to FIGS. 2A and 2B , FIG. 2A illustrates application of vertical mode streaming to a smartphone. In recent live commerce (live commerce), such a vertical mode has become a trend. Here, live commerce means an online channel that sells products through real-time video streaming, and has recently been actively used as the untact economy that pursues non-face-to-face contact has emerged. However, most of the current vertical mode streaming methods are produced/transmitted using a smartphone. In other words, as shown in FIG. 2B, when a video is photographed vertically using a smartphone, bitstream formatted, and transmitted, users can decode the video on their smartphone and enjoy the video in portrait mode.

Referring to FIGS. 3A to 3D , FIG. 3A shows the appearance of a camera for general broadcasting. The camera 100 for broadcasting may include a camera body 110 and a display unit 120 . The camera body 110 is a key part of a camera that captures an object using a lens and an image sensor, processes the image, and captures a target image, and the display unit 120 displays the image captured by the camera body 110 in real time. It may be a display part. When an image is captured by the camera 100 for broadcasting, as can be seen through the screen of the display unit 120 in FIG. 3B , the image of the subject can be captured and displayed at a horizontal:vertical ratio of 16:9. Here, the display of an image on the display unit 120 may correspond to image streaming.

Suppose that a video is generally photographed using the broadcasting camera 100 and a bitstream format is performed by rotating the corresponding video by 90° for portrait mode streaming. For example, when generally photographed using the broadcasting camera 100, the photograph is taken in a landscape mode as shown in FIG. 3c, and when the photographed image is rotated by 90°, the image may be laid down as shown in FIG. 3d. In other words, the person on the screen is laid on its side. If such an image is transmitted after bitstream formatting, the same image can be displayed on a user's smart phone. When the user rotates the smartphone to see the person straight, the corresponding image becomes smaller and appears only on a part of the screen of the smartphone. Therefore, in the case of general shooting using the broadcasting camera 100, it may not match the intention of optimizing and utilizing the entire screen of the smart phone through portrait mode streaming.

Referring to FIGS. 4A and 4B , FIG. 4A shows a state in which the broadcasting camera 100R is rotated 90° counterclockwise from a normal position for portrait mode shooting and streaming. Depending on the embodiment, there is no problem even if the broadcasting camera 100R is rotated clockwise by 90° from a general position. In other words, the display unit 120 may be rotated downward. 4B shows an image captured by a rotated broadcasting camera 100R. In the image of FIG. 4B , it can be seen that the vertical length of the subject is long. That is, the image of FIG. 4B may correspond to an image captured in portrait mode. Subsequent processes are the same as described above. That is, an image photographed in portrait mode is rotated by 90°, and the rotated image is formatted as a bitstream and transmitted through a network. Thereafter, through vertical mode streaming, the user can display the same image as the image shown in FIG. 4B in full screen on his or her smartphone.

In the portrait mode streaming method of the present embodiment, in shooting using a plurality of broadcast cameras, each of the broadcast cameras is rotated clockwise or counterclockwise by 90° to shoot in portrait mode, and then the image rotation is reversed to produce a bit stream. By formatting and transmitting, an image reproducing device, for example, a smartphone, can directly display the corresponding image in portrait mode according to the aspect ratio. Therefore, the portrait mode streaming method of this embodiment can provide an optimal image to the entire screen of a smart phone.

5A and 5B are pictures for explaining other utilization methods in the vertical mode streaming method of FIG. 1 .

Referring to FIG. 5A, in the vertical mode streaming method of the present embodiment, each of the at least two broadcasting cameras 100 is rotated clockwise or counterclockwise by 90° to take pictures in portrait mode, and the captured images are rotated 90° in the opposite direction. After rotation, streaming may be performed, but all of the images of at least two broadcasting cameras 100 may be streamed, or only the images of the selected at least one broadcasting camera 100 may be streamed.

For example, as shown in FIG. 5A, each of the four broadcasting cameras 100-1, 100-2, 100-3, and 100-4 is rotated clockwise or counterclockwise by 90° to shoot in portrait mode, , After rotating the captured images by 90°, all of the images of the four broadcasting cameras 100-1, 100-2, 100-3, and 100-4 can be streamed. Also, depending on the embodiment, only one or two selected images of the four broadcasting cameras 100-1, 100-2, 100-3, and 100-4 may be streamed. In broadcasting terms, a technique of selecting and streaming only a part of several images is called cutting. On the other hand, in terms of the concept of a channel, streaming all the images of the four broadcasting cameras (100-1, 100-2, 100-3, 100-4) corresponds to 4-channel broadcasting, and the selected one Alternatively, when only two are streamed, it may correspond to one-channel broadcasting or two-channel broadcasting. In addition, the vertical mode streaming method of this embodiment may include a video switching function that switches each other in a plurality of channels.

Referring to FIG. 5B, in the vertical mode streaming method of this embodiment, as shown on the left side of FIG. In addition, as shown on the right side of FIG. 5B, the image of the first broadcasting camera 100-1 may be streamed in portrait mode so that a logo or text subtitle is displayed together.

Additionally, the portrait mode streaming method of this embodiment may include a Picture In Picture (PIP)/chroma key function. In addition, the vertical mode streaming method of this embodiment can simultaneously transmit to three platforms (using the same protocol), transmit variable bitrate streams, specify codec/resolution/compression rate during recording, and individually record 4 channels. (PGM separate) can be done. Meanwhile, in the case of simultaneous transmission of platforms, it is of course possible to simultaneously transmit to four or more platforms without being limited to three.

6 is a flowchart schematically illustrating a process of a vertical mode streaming method according to an embodiment of the present invention, FIG. 7 is a picture for explaining a UHD camera in relation to the vertical mode streaming method of FIG. 6, and FIG. In the portrait mode streaming method of FIG. 6 , these are pictures showing small images obtained from images of a UHD camera. The contents already described in the description of FIGS. 1 to 5B are briefly described or omitted.

Referring to FIGS. 6 and 7 , in the vertical mode streaming method of this embodiment, first, an object is photographed with a UHD (Ultra HD) camera (S110a). A UHD camera may refer to a camera capable of capturing UHD images. For reference, UHD was called various names right before the next-generation standard after HD was enacted, and 4K was first named. 4K is not defined precisely, but means that the horizontal resolution has a resolution of about 4000 pixels. In the movie side, 4096 x 2160 resolution was used under the name of 4K DCI first, and there were several other 4K specifications. While several standards competed, the resolution of 3840x2160, which is 9 times (3 times the width x 3 times the height) of HD (1280x720) and 4 times (2 times the width x 2 times the height) of FHD (1920x1080), became the mainstream, and eventually 4K It was decided to name it UHD.

In FIG. 7 , a screen indicated by 1280 on the x-axis may correspond to an HD screen, and a screen indicated by 3840 on the x-axis may correspond to a UHD screen. As can be seen from FIG. 7 , a UHD screen can be 3 times larger horizontally and 3 times vertically when compared to an HD screen, based on the same resolution. For reference, a screen marked with 640 on the x-axis corresponds to a Video Graphics Array (VGA) screen, and a screen marked with 1920 on the x-axis may correspond to a Full HD (FHD) screen.

Next, the image captured by the UHD camera is divided into several small images with a long vertical image, or a specific part is extracted from a small image with a long vertical image (S120a). Hereinafter, for convenience, a 'long vertical small video' is referred to as a 'portrait mode small video'. 8 shows small images obtained by extracting a part of an image captured by a UHD camera (hereinafter referred to as 'UHD image') in a vertical mode form, that is, small images in a vertical mode. As can be seen from FIG. 7 , since UHD video is about 9 times larger than an image captured by an HD camera, which is a camera for general broadcasting, a portion of the UHD video can be cut and extracted as a small video in portrait mode. For reference, in broadcasting terms, a technique of cutting a large image and extracting it into a small image is called crop.

On the other hand, when dividing a UHD image into 9 small images in vertical mode, the UHD image may be possible only in vertical mode. Accordingly, in the step of photographing the subject with the UHD camera (S110a), the UHD camera may be photographed in portrait mode by rotating the UHD camera clockwise or counterclockwise by 90°, similar to a broadcasting camera. Thereafter, in the step of dividing into small images or extracting a specific part from the small images (S120a), the portrait mode UHD image may be divided into 9 vertical mode small images.

Subsequently, images are streamed in portrait mode (S130). Streaming in vertical mode is as described in the description of FIG. 1 . However, here, the images may correspond to small images divided from a UHD image or small images extracted from a specific part.

In addition, photographing an object with a UHD camera is the same as described in the description of FIG. 6 .

Next, the images of the broadcast camera are rotated 90° counterclockwise or counterclockwise, and the image of the UHD camera is divided into several small images that are vertically long, or a specific part is divided into small images that are vertically long. Extract (S120b). Rotating the images of the broadcast camera counterclockwise or counterclockwise by 90° is the same as described in the description of FIG. 1 . In addition, dividing the image of the HD camera into several small images with a long vertical image or extracting a specific part from a small image with a long vertical image is the same as described in the description of FIG. 6 .

Thereafter, all images are streamed or at least one selected image is streamed (S130a). Streaming of all images or streaming of at least one selected image is the same as described in the description of FIG. 5A. Meanwhile, here, the images may be small images segmented or extracted from images of broadcasting cameras and/or UHD images.
