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

Figure 1 is a flowchart schematically showing the process of a portrait mode streaming method according to an embodiment of the present invention, and Figures 2A and 2B are photos showing the portrait mode streaming method of Figure 1 applied to a smartphone. . FIGS. 3A to 3D are photos and plan views showing problems resulting from the application of a general portrait mode streaming method in a broadcast camera, and FIGS. 4A and 4B show the shooting method and the resulting method in the portrait mode streaming method of FIG. 1. These are photos that show the video.

Referring to FIG. 1, in the portrait mode streaming method of this embodiment, each of at least two broadcast cameras is first rotated 90° clockwise or counterclockwise to photograph the subject so that the subject appears longer (S110). Here, the broadcast camera (see 100 in FIG. 3A or 100R in FIG. 4A) may refer to a general camera used in broadcasting stations. The broadcast cameras 100 and 100R may be, for example, HD (High Definition) cameras. Depending on the embodiment, the broadcast cameras 100 and 100R may be replaced with freely mobile HD camcorders. Usually, broadcast cameras (100, 100R) can photograph an object so that it appears horizontally. For example, the broadcast cameras 100 and 100R can photograph an object with a horizontal:vertical screen ratio of 16:9. Here, horizontal may refer to the x-axis and vertical may refer to the y-axis. Therefore, shooting an object so that the width is long means shooting the image so that the there is. In the explanation below, for convenience, 'photographing an object so that the width appears long' is referred to as 'shooting in landscape mode', and 'photographing an object so that the length appears long' is referred to as 'shooting in portrait mode.' Meanwhile, the step of photographing in portrait mode (S110) 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, if the object is photographed by rotating it 90° clockwise, the captured image is rotated 90° counterclockwise, and if the object is photographed by rotating it 90° counterclockwise, the captured image is rotated 90° counterclockwise. Rotate 90° clockwise. In this way, rotating the captured images to their original positions may be for streaming in the next step. Additionally, rotation of the captured image can be performed through image processing software. To be more specific, when shooting in portrait mode, the image processing software saves the captured image, that is, the image taken vertically, with a fixed aspect ratio, and rotates the image with the fixed aspect ratio by 90°. , the rotated video can be encoded with additional information and formatted into a bitstream.

Afterwards, the videos are streamed in vertical mode (S130). Here, streaming may refer to a technology that plays audio, video, animation, etc. on the Internet in real time without separately storing it. For example, in the portrait mode streaming method of this embodiment, this may mean playing a video previously captured on a smartphone in portrait mode. More specifically, the bitstream for the video previously taken in portrait mode may be transmitted to a video playback device through a network. Additionally, the video playback device can play the video by decoding the received bitstream. Here, the video playback device may be a smartphone, and the video may be directly displayed in portrait mode according to the screen ratio of the smartphone.

Referring to FIGS. 2A and 2B, FIG. 2A shows portrait mode streaming applied to a smartphone. Recently, this vertical mode has become a trend in live commerce. Here, live commerce refers to an online channel that sells products through real-time video streaming, and has been actively used recently with the rise of the untact economy that pursues non-face-to-face and non-contact. However, most of the current vertical mode streaming methods are produced and transmitted using smartphones. In other words, as shown in Figure 2b, when a video is captured vertically using a smartphone, formatted as a bitstream, 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 external appearance of a general broadcasting camera. The broadcast camera 100 may include a camera body 110 and a display unit 120. The camera body 110 is a core part of the camera that captures the target using a lens and an image sensor, processes the image, and captures the target image. 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 with the broadcast camera 100, as can be seen through the screen of the display unit 120 of FIG. 3B, the image of the target may be captured and displayed at a width:vertical ratio of 16:9. Here, the display of the image on the display unit 120 may correspond to video streaming.

Let's say that a broadcast camera 100 is used to film a video, and for portrait mode streaming, the video is rotated 90° and a bitstream format is performed. For example, when generally filming using the broadcast camera 100, the picture is taken in landscape mode as shown in FIG. 3C, and if the captured image is rotated 90°, it can become a flat image as shown in FIG. 3D. In other words, the person on the screen is laid on his side. If such video is formatted as a bitstream and transmitted, the same video can be displayed on the user's smartphone. When the user rotates the smartphone to see the person directly, the image becomes smaller and appears only on a portion of the smartphone screen. Therefore, in the case of general shooting using the broadcast 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 the broadcast camera 100R rotated 90° counterclockwise from its normal position for portrait mode shooting and streaming. Depending on the embodiment, there is no major problem even if the broadcast camera 100R is rotated 90° clockwise from its normal position. In other words, the display unit 120 may be rotated to go downward. Figure 4b shows an image captured by a rotated broadcast camera (100R). In the image of Figure 4b, it can be seen that the subject is elongated. That is, the image in FIG. 4B may correspond to an image captured in portrait mode. The subsequent process is the same as described above. In other words, the video captured in portrait mode is rotated by 90°, the rotated video is formatted as a bitstream, and then transmitted over the network. Thereafter, through portrait 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 this embodiment, in shooting using a plurality of broadcast cameras, each of the broadcast cameras is rotated 90° clockwise or counterclockwise to shoot in portrait mode, and then the image rotation is reversely rotated to stream the bitstream. By formatting and transmitting, the video can be displayed directly in portrait mode according to the screen ratio on a video playback device, such as a smartphone. Therefore, the portrait mode streaming method of this embodiment can provide optimal video on the entire screen of the smart phone.

FIGS. 5A and 5B are photos to explain other utilization methods in the vertical mode streaming method of FIG. 1.

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

For example, as shown in FIG. 5A, each of the four broadcast cameras 100-1, 100-2, 100-3, and 100-4 is rotated 90° clockwise or counterclockwise and photographed in portrait mode. , after rotating the captured images by 90°, all images from the four broadcast cameras (100-1, 100-2, 100-3, and 100-4) can be streamed. Additionally, depending on the embodiment, only one or two selected images from four broadcast cameras (100-1, 100-2, 100-3, and 100-4) may be streamed. In broadcasting terms, the technology of selecting and streaming only a portion of multiple videos is called cutting. Meanwhile, if explained in terms of the concept of a channel, streaming all images from four broadcast cameras (100-1, 100-2, 100-3, and 100-4) corresponds to a 4-channel broadcast, and one selected Alternatively, if only two streams are streamed, it may correspond to one-channel broadcasting or two-channel broadcasting. Additionally, the portrait mode streaming method of this embodiment may include a video switching function that switches between multiple channels.

Referring to FIG. 5B, in the portrait mode streaming method of this embodiment, as shown on the left of FIG. 5B, images such as file players or front subtitles, rather than images from broadcast cameras, can be streamed in portrait mode. Additionally, as shown on the right side of FIG. 5B, the image from the first broadcast camera 100-1 may be streamed in portrait mode so that a logo or text subtitles are 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 be transmitted simultaneously to three platforms (using the same protocol), can transmit a variable bitrate stream, can specify codec/resolution/compression rate when recording, and can also record 4 channels individually. (PGM separately) can be done. Meanwhile, in the case of simultaneous platform transmission, it goes without saying that simultaneous transmission can be made to four or more platforms, not limited to three.

FIG. 6 is a flowchart schematically showing the process of a portrait mode streaming method according to an embodiment of the present invention, FIG. 7 is a photograph for explaining a UHD camera in relation to the portrait mode streaming method of FIG. 6, and FIG. 8 is a These are photos showing small images obtained from images of a UHD camera in the portrait mode streaming method of Figure 6. Contents already described in the description portion of FIGS. 1 to 5B will be briefly described or omitted.

Referring to FIGS. 6 and 7 , in the portrait 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 that can shoot UHD video. For reference, UHD was called by various names just before establishing the next-generation standard after HD, and the first one that made a name for itself was 4K. 4K is not exactly defined, but means that the horizontal resolution is approximately 4000 pixels. On the movie side, 4096 x 2160 resolution was first used under the name 4K DCI, and there were several other 4K specifications. As various standards competed, 3840x2160 resolution, which is 9 times the resolution of HD (1280x720) (3 times the width The name UHD was decided.

In FIG. 7, the screen indicated at 1280 on the x-axis may correspond to an HD screen, and the screen indicated at 3840 on the x-axis may correspond to a UHD screen. As can be seen in Figure 7, based on the same resolution, a UHD screen can be three times larger horizontally and three times larger than an HD screen. For reference, the screen displayed at 640 on the x-axis may correspond to a VGA (Video Graphics Array) screen, and the screen displayed at 1920 on the x-axis may correspond to a FHD (Full HD) screen.

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

Meanwhile, splitting a UHD video into 9 small images in vertical mode may only be possible if the UHD video is in vertical mode. Therefore, in the step of photographing an object with a UHD camera (S110a), similar to a broadcast camera, the UHD camera can be rotated 90° clockwise or counterclockwise and photographed in portrait mode. Thereafter, in the step of dividing into small images or extracting a specific portion from the small images (S120a), the portrait mode UHD image may be divided into nine portrait mode small images.

Continuing, the videos are streamed in portrait mode (S130). Streaming in vertical mode is the same as described in the description of FIG. 1. However, here, the images may be small images divided from a UHD video or small images extracted from a specific part.

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

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

Afterwards, all the videos are streamed, or at least one selected video is streamed (S130a). Streaming all videos or streaming at least one selected video is the same as described in the description of FIG. 5A. Meanwhile, here, the images may be images from a broadcast camera and/or small images divided or extracted from UHD images.
