Technical Field
The present disclosure relates to the field of audio and video technologies, and in particular, to a video receiving method and apparatus, and a video sending method and apparatus.
Background
Recently, a function of panorama live (e.g., 360 ° panorama live) has been implemented. The panoramic live broadcast mode refers to that a user terminal such as a mobile phone and a tablet computer is used for looking around videos through user operations (for example, terminal rotation, gesture sliding, zooming and the like) so as to realize watching of panoramic videos up, down, left and right, and provide an immersive watching experience for a user. However, due to the fact that the effective visual area is small due to the panoramic video rendering principle, even if 4K ultra-high definition panoramic live broadcasting is adopted, the definition perceived by a user is not enough, and the image quality is not enough. For example, in 2020China Joy exhibition, the function of panoramic live broadcasting exhibition is supported, a user can watch the performance of four surrounding exhibition stands by rotating a mobile phone, but the machine position of the panoramic camera is a fixed position, the machine position is far away, the panoramic camera is not moved by hands, the visual effect of the image quality is not good, and the requirement that the user can only stay for a long time by the curiosity of the user can be met. In addition, the user terminal with a small screen such as a mobile phone or a tablet is difficult to finish self-view-angle selection interaction, and more live broadcast parties switch, so that the user terminal does not necessarily accord with the preference of all users.

Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The embodiments described in the following examples do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In this case, the expression "at least one of the items" in the present disclosure means a case where three types of parallel expressions "any one of the items", "a combination of any plural ones of the items", and "the entirety of the items" are included. For example, "include at least one of a and B" includes the following three cases in parallel: (1) comprises A; (2) comprises B; and (3) comprises A and B. For another example, "at least one of the first step and the second step is performed", which means that the following three cases are juxtaposed: (1) executing the step one; (2) executing the step two; and (3) executing the step one and the step two.
Regarding the panoramic video, an equidistant cylindrical Projection (ERP) is taken as an example, where ERP is a sphere model that calculates a visible area according to a normal field angle (FOV) of 90 °, and only 1/8 of the visible area can be seen, that is, the left and right surround a circle of 360 ° up and down 180 ° (90/360) ((90/180)). Even at a resolution of 4K, the visual effect of the visible region is not as good as that of the plain video 1080P. Aiming at the problem of low picture quality of panoramic video, if the quality of panoramic live broadcast is improved by improving the resolution, more bandwidth waste can be brought. In addition, if panoramic live broadcasting is carried out without interaction, the picture quality is inferior to that of the live broadcasting of an ordinary single-machine position, and the live broadcasting of the ordinary single-machine position can also enable a user to switch different machine positions to watch in multiple visual angles.
Therefore, the present disclosure provides a new panoramic video receiving or transmitting method, which directly switches between a panoramic video stream and a normal single-machine-position video stream based on user interaction and view angle calculation by combining the view angle direction and the single-machine-position view angle direction of a panoramic video, so as to meet the requirement that a user desires to watch high-definition video content at a certain view angle while watching a panoramic video live broadcast (or on demand) and the requirement that the user can conveniently switch view angles without exiting an application to reselect live broadcast content. Hereinafter, a video receiving method and apparatus and a video transmitting method and apparatus according to exemplary embodiments of the present disclosure will be described in detail with reference to fig. 1 to 7.
Fig. 1 is a diagram illustrating an implementation scenario of a video receiving method and a video transmitting method according to an exemplary embodiment of the present disclosure.
Referring to fig. 1, in constructing a panoramic live room 100 according to an exemplary embodiment of the present disclosure, the panoramic live room 100 may be provided with a plurality of exhibition halls (e.g., four exhibition halls surrounded all around), and a panoramic camera 101 (here, a camera is a general term of a device having a photographing function) may be provided at the center of the plurality of exhibition halls, and a multi-booth general camera corresponding to the plurality of exhibition halls, e.g., general cameras 102, 103, 104, and 105, may be provided with the panoramic camera as a center. For example, one or more stands may be set for each exhibition hall.
In live broadcasting, the panoramic camera 101 and the plurality of one-position general cameras 102, 103, 104, and 105 may transmit respective photographed video streams to the server 110. The server 110 may process the received video stream to generate a live program for distribution to one or more user terminals, e.g., user terminals 120 and 130, entering the panoramic live room 100. The user terminals 120 and 130 may present the received live program to the user, thereby implementing live program for the panoramic live broadcast room 100. Here, the server 110 may be a network device capable of providing a webcast service, and the user terminals 120 and 130 may be electronic devices such as a mobile phone, a tablet computer, a wearable device, a personal computer, a personal digital assistant, and a cloud computing device. The user terminals 120 and 130 may obtain live programs through clients (e.g., applications installed therein or web applications integrated in browsers). Hereinafter, the interaction of the user terminals 120 and 130 with the server 110 may be an interaction of a client in the user terminals 120 and 130 with the server 110.
In addition, the clients in user terminals 120 and 130 may also play on-demand programs. At this time, the video streams taken by each of the panoramic camera 101 and the plurality of one-position ordinary cameras 102, 103, 104, and 105 or live programs generated by the server 110 may be saved into a memory (e.g., cloud storage) associated with the server 110. When user terminals 120 and 130 perform an on-demand operation, server 110 may transmit the on-demand program to user terminals 120 and 130.
Specifically, the panoramic camera 101 may include a plurality of cameras, each camera has a different viewing angle, and the general videos captured by each camera may be spliced into a panoramic video in a splicing manner, and the plurality of cameras include a main camera, the direction of the main camera is a main viewing angle direction, and video content in the main viewing angle direction is played when the panoramic video is just played. Accordingly, the panoramic video stream photographed by the panoramic camera 101 may include stitched panoramic video content and video metadata (metadata) information. Here, the video meta information may include a rendering model of the panoramic video and main view direction information. Further, each of the plurality of one-position video streams captured by the plurality of one-position general cameras 102, 103, 104, and 105 may include one-position video content and corresponding position information.
After obtaining the panoramic video stream and the multiple single-machine-position video streams, the server 110 may calculate the view direction of each single-machine-position video with reference to the main view direction of the panoramic video based on the received machine-position information of each single-machine-position video. For example, the viewing direction may be characterized by an angle value, which may range between 0 and 360 °. In addition, the server 110 may also generate video addresses (e.g., uniform Resource Locators (URLs)) for the panoramic video stream and the multiple one-bit video streams from the storage addresses of the panoramic video stream and the multiple one-bit video streams. The server 110 may correspond the view direction information of the plurality of stand-alone videos to the video addresses one-to-one, and issue the video addresses of the panoramic video stream and the video addresses and the corresponding view direction information of the plurality of stand-alone video streams to the user terminal 120 or 130. For example, the server 110 may encode the video address of the panoramic video stream to be transmitted and the video addresses of the multiple one-machine-bit video streams and the corresponding view direction information into a data array, and transmit the encoded data array to the user terminal 120 or 130 through the Json encapsulation file. In addition, the Json package file may also include other information of the panoramic video stream and the plurality of one-machine-bit video streams, such as ID information and the like. Here, the delivery timing of the server 110 may be delivered when the user terminal 120 or 130 requests a live program (or an on-demand program) for the first time, or may be delivered during a live program (or an on-demand program). For example, when the user terminal 120 or 130 first requests a live program (or an on-demand program), the video address is not yet clear, and the video address can be sent during the live program (or the on-demand program). For another example, when a video address fails, the user terminal 120 or 130 may request the server 110 to refresh the live address again, at which time the server 110 may issue in response to the request.
When the user terminal 120 or 130 requests the server 110 for a panorama live program (or panorama on-demand program) for the first time, the server 110 may issue a panorama video stream to the user terminal 120 or 130, and simultaneously issue a video address of the panorama video stream and video addresses of a plurality of one-machine-level video streams and corresponding view direction information (e.g., angle values), for example, a Json package file. The user terminal 120 or 130 may parse the panoramic video stream and play the panoramic video when receiving the panoramic video stream. In addition, when the user terminal 120 or 130 receives the video addresses of the panoramic video stream and the video addresses of the multiple one-machine-bit video streams and the corresponding view direction information, the video addresses of the panoramic video stream and the video addresses of the multiple one-machine-bit video streams and the corresponding view direction information can be analyzed and stored. Of course, as described above, the server 110 may also issue the video addresses of the panoramic video stream and the video addresses of the multiple one-machine-level video streams and the corresponding view direction information (e.g., angle value) during the live (or on-demand) process.
The panoramic video stream received by the user terminal 120 or 130 may include video meta information, which may include a rendering model (e.g., a 360 ° rendering model) of the panoramic video and a main viewing angle. Here, the main view refers to a first view in the case of first play. That is, when the user terminal 120 or 130 plays the panoramic live broadcast (or on demand) for the first time, the video frame seen by the user is the video frame of the main viewing angle. In the process that a user watches panoramic live broadcast (or video on demand), video pictures of other visual angles can be switched and watched based on a rendering model through operations of rotating a user terminal, sliding gestures, clicking buttons and the like. Next, a process of the user terminal 120 or 130 switching a viewing angle of a panorama live (or on-demand) video will be described.
When the user terminal 120 or 130 receives a signal of view angle switching through a sensor (e.g., a gyroscope, an acceleration sensor, etc.) or a specific gesture or button, etc., the projection matrix may be recalculated based on a rendering model of the panoramic video. For example, when the user terminal 120 or 130 monitors the gyroscope, the gravity-induced acceleration and the magnetic field acceleration in the gyroscope are obtained, a motion matrix is obtained by a system method, and the motion matrix is converted into a final rotation matrix as a projection matrix by rendering model view conversion. Therefore, the user terminal 120 or 130 may obtain the switched view angle according to the recalculated projection matrix, and switch the panoramic video picture to the video picture of the view angle.
According to an exemplary embodiment of the present disclosure, a panoramic live (or on-demand) is played using a panoramic video by default, but when it is detected that a user is interested in some content of a current panoramic video picture, the user terminal 120 or 130 may switch the current panoramic video picture to a one-machine-position video picture having a machine-position view angle corresponding to a playing view angle of the current panoramic video picture, so as to bring about a clearer video viewing experience for the content concerned by the user.
Specifically, the user terminal 120 or 130 can calculate the current mobile phone orientation through the calculated projection matrix, and the orientation is converted into an angle of 0 to 360 degrees through an algorithm, so that the panoramic video rotates once to return to the origin. For example, the radian of the stereo coordinate system is obtained by transforming the projection matrix into Euler angles, wherein the projection matrix can be a 4*4 matrix, which is stored in a one-dimensional array form, R0 … R15. Thus, the radians of the stereo coordinate system can be calculated as x = (float) atan2 (R1, R5); y = (float) asin (-R9); z = (float) atan2 (-R8, R10). The radians of the stereo coordinate system can then be converted into angles of the planes, i.e. radians 180.0/PI. The angle can be used as the azimuth angle of the current mobile phone, namely the playing view angle of the current panoramic video picture. The user terminal 120 or 130 may search for a booth viewing angle corresponding to a play viewing angle of the current panoramic video picture from among previously parsed and saved booth viewing angles of the plurality of booth videos. For example, the user terminal 120 or 130 may calculate a difference between the machine view angles of the plurality of single-machine videos and the current playing view angle of the panoramic video, and determine a machine view angle having a smallest difference from the current playing view angle of the panoramic video and the difference being within a predetermined range (e.g., ± 10 °) as the corresponding machine view angle. If the difference value is not in the preset range, the corresponding machine position visual angle does not exist, namely, aiming at the playing visual angle of the current panoramic video picture, the common video of the single machine position does not exist. And if the corresponding machine position visual angle is searched, indicating that a common video of a single machine position exists for the playing visual angle of the current panoramic video picture. Of course, the user terminal 120 or 130 may search for the stand view angle of the corresponding one-stand video using any feasible method.
When the user terminal 120 or 130 searches for a machine view angle of a corresponding one-machine video, the user terminal 120 or 130 may search for a video address of the one-machine video from among previously parsed and stored video addresses of a plurality of one-machine videos, and transmit a request including the searched video address to the server 110. After receiving the request, the server 110 searches for a corresponding one-machine-digit video based on the request including the video address, and transmits the searched one-machine-digit video to the user terminal 120 or 130, while stopping transmitting the panoramic video. When the user terminal 120 or 130 receives the one-machine-position video, it may switch to play the panoramic video to play the one-machine-position video having a view angle corresponding to a current play view angle of the panoramic video. In addition, the user terminal 120 or 130 may perform synchronous switching between videos using a video time stamp drop frame synchronization method or a low-latency transmission protocol. For example, the video stream may include timestamp information (e.g., decoding Time Stamp (DTS) and Presentation Time Stamp (PTS)), and the user terminal 120 or 130 may perform frame dropping processing using the parsed PTS information to achieve the effect of audio video synchronization. For another example, the user terminal 120 or 130 may perform low-delay processing using a low-latency transmission protocol to achieve the effect of low-delay audio and video synchronization.
According to an exemplary embodiment of the present disclosure, when a switching operation of a user is detected, it may be regarded that content in which the user is interested is detected. The switching operation may include, but is not limited to, a user performing a gesture zoom-in operation (for example, the gesture zoom-in operation achieves a zoom-in lens to view the content), performing various operations such as long-pressing or clicking on the specified content, and the like, a user staying at a certain viewing angle for a long time (for example, staying at a certain viewing angle for more than a predetermined time) when the user switches the viewing angle by turning on the gyroscope, and the like.
According to an example embodiment of the present disclosure, when the user terminal 120 or 130 receives an operation to exit the one-machine-position video playing (e.g., gesture zoom, touch back button, etc.) while playing the one-machine-position video, the request for the panoramic video (e.g., a video address that may include a previously parsed and saved panoramic video) may be re-sent to the server 110. The server 100, upon receiving the request, transmits the panoramic video to the user terminal 120 or 130, and terminates the transmission of the one-machine-level video. When receiving the panoramic video, the user terminal 120 or 130 may switch the playback single-player video to playback the panoramic video. At this time, the playing view angle of the switched panoramic video needs to correspond to the machine position view angle of the single-machine position video before switching, so as to protect the synchronism. In addition, the user terminal 120 or 130 may perform synchronous switching between videos using a video time stamp drop frame synchronization method or a low-latency transmission protocol.
According to an exemplary embodiment of the present disclosure, when the user terminal 120 or 130 is playing a video (e.g., a panoramic video or a one-seater video), information of one or more panoramic views or one-seater views may be provided. When the user selects one viewing angle from the information of the one or more panoramic viewing angles or one-machine viewing angles, the user terminal 120 or 130 may switch playing the current video to playing the panoramic video or the one-machine video having the viewing angle selected by the user. In addition, the user terminal 120 or 130 may perform synchronous switching between videos using a video time stamp drop frame synchronization method or a low-latency transmission protocol.
In particular, the information may include, but is not limited to, animations, maps, thumbnails or thumbnail videos, etc. regarding the one or more panoramic views or single-machine views.
The manner of providing may include, but is not limited to, providing the information in a partial area of the current video interface, providing a shortcut button in a partial area of the current video interface, and displaying a folder when a user touches the shortcut button to provide the information.
The one or more panoramic or single-airplane-position perspectives may include all panoramic or single-airplane-position perspectives for a user to conveniently switch any of the perspectives of interest, and/or may include currently popular panoramic or single-airplane-position perspectives (e.g., the most numerous perspectives viewed by the full-network user) for a user to select a currently comparatively popular perspective, and/or may include the most numerous panoramic or single-airplane-position perspectives viewed by the user himself for a user to conveniently and quickly switch back to the most-desired perspective, and/or other possible panoramic or single-airplane-position perspectives.
For example, the server 110 may periodically determine the current hot panoramic view angle or single-airplane-seat view angle according to the full-network playing situation, and push the determined current hot panoramic view angle or single-airplane-seat view angle to the user terminal 120 or 130, and the user terminal 120 or 130 may provide the information of the current hot panoramic view angle or single-airplane-seat view angle for the user to view or select while playing the video when receiving the message of the current hot panoramic view angle or single-airplane-seat view angle.
For another example, the user terminal 120 or 130 may generate a button corresponding to each panoramic view angle and the one-machine view angle based on a rendering model and a main view angle of a previously parsed and saved panoramic video and a bit machine view angle and a video address of a plurality of one-machine videos, save the buttons in an interlayer of a screen, display an interlayer button on a current layer of the screen, and when a user touches the interlayer button, display a button corresponding to each panoramic view angle and one-machine view angle, so that the user may arbitrarily select and switch to a desired view angle.
As another example, the user terminal 120 or 130 may determine the most frequent viewing angles viewed by the user from the user's history, and provide information on the most frequent viewing angles viewed by these users while playing the video, and the user may quickly switch back to the most desired viewing angle by selecting such information.
Further, in addition to switching different view angles of the panoramic video, the user terminal 120 or 130 needs to send a request for the panoramic video or the one-machine-position video having the selected one-machine-position view angle to the server 110 before switching the playing panoramic video to the playing one-machine-position video or switching the playing one-machine-position video to the playing panoramic video or other one-machine-position video. The server 110, upon receiving the request, transmits the requested panoramic video or the one-seater video to the user terminal 120 or 130, and terminates transmission of the previously transmitted video. The user terminal 120 or 130 switches to play the panoramic video with the selected panoramic view angle or the single-machine-site video with the selected single-machine-site view angle when receiving the panoramic video or the single-machine-site video.
For example, the user terminal 120 or 130 is currently playing a panoramic video, receives a push of a currently hot panoramic view from the server 110, and may display the received information of the currently hot panoramic view in a predetermined area in the currently playing panoramic video interface. When the user selects this information, the user terminal 120 or 130 may directly switch to a screen of the current popular panoramic view angle based on the rendering model.
For another example, the user terminal 120 or 130 is currently playing a panoramic video, receives a push of the current hit-list view angle from the server 110, and may display the received information of the current hit-list view angle in a predetermined area in the currently playing panoramic video interface. When the user selects this information, the user terminal 120 or 130 may send a request to the server 110 for the one-machine video with the current popular one-machine view. The server 110 may transmit the one-machine video having the current popular one-machine view angle to the user terminal 120 or 130 and terminate transmission of the panoramic video. When the user terminal 120 or 130 receives the one-machine video having the current popular one-machine view angle, the playing panoramic video is switched to play the one-machine video having the current popular one-machine view angle.
Fig. 2 is a flowchart illustrating a video receiving method performed by the user terminal 120 or 130 according to an exemplary embodiment of the present disclosure.
Referring to fig. 2, in step 201, while playing the panoramic video, in response to receiving the first switching operation, a second request for a first one-position video of the plurality of one-position videos may be sent to the server 110, and the first one-position video may be received from the server 110 and reception of the panoramic video may be terminated. Here, the panoramic video and the plurality of single-machine-bit videos are photographed in the same scene. For example, in a shooting scene of the live broadcast room 100 as shown in fig. 1, a panoramic video may be shot by a panoramic camera disposed at the center of a plurality of exhibition halls surrounded all around, and a plurality of booth videos may be shot by a plurality of general cameras for the plurality of exhibition halls disposed with the panoramic camera as a center. In addition, the stand view angle of the first single-stand video may correspond to a current playing view angle of the panoramic video.
According to an example embodiment of the present disclosure, before playing the panoramic video, a second request for the panoramic video may be sent to the server, and the panoramic video may be received from the server to play the panoramic video.
According to an example embodiment of the present disclosure, video information of the plurality of one-machine videos may be received from the server 110 after the second request is transmitted. For example, video information for a plurality of one-machine videos may also be received from the server 110 at the same time as the panoramic video from the server 110. Alternatively, the video information of the plurality of one-player videos may be received from the server 110 in the process of playing the panoramic video.
According to an exemplary embodiment of the present disclosure, a panoramic video may include panoramic video content and video meta information, which may include a rendering model and main view angle information of the panoramic video. When the panoramic video is played for the first time, the main visual angle video picture of the panoramic video is played by default. In the process of watching the panoramic video by the user, the video pictures at other visual angles can be switched and watched based on the rendering model through operations of rotating the user terminal, sliding gestures, clicking buttons and the like.
According to an exemplary embodiment of the present disclosure, the first switching operation may refer to an operation of switching from playing a panoramic video to playing a one-machine-position video. The first switching operation may include, but is not limited to, a user performing a gesture zoom-in operation (for example, the gesture zoom-in operation achieves a zoom-in lens to view content), performing various operations such as a long press or a click on a designated content, a user staying at a certain viewing angle for a long time (for example, staying at a certain viewing angle for more than a predetermined time) when the user turns on the gyroscope to switch the viewing angle, and the like. According to an example embodiment of the present disclosure, the first one-machine-bit video may be determined from the plurality of one-machine-bit videos based on video information of the plurality of one-machine-bit videos received from the server 110. For example, the frequency information may include a machine view angle and a video address for each of the plurality of single-machine videos. The first single-machine-position video with the first machine-position visual angle can be determined by acquiring the current playing visual angle of the panoramic video and searching the first machine-position visual angle corresponding to the current playing visual angle of the panoramic video from the machine-position visual angles of the plurality of single-machine-position videos. Alternatively, a machine position view angle at which the difference from the current play view angle of the panoramic video is the smallest and the difference is within a predetermined range (e.g., ± 10 °) may be determined as the first machine position view angle by calculating the difference between the machine position view angles of the plurality of single-machine position videos and the current play view angle of the panoramic video, respectively. In the case that the first booth perspective is searched, a first request for the determined first booth video may be sent to the server 110, wherein the first request includes a video address of the first booth video having the first booth perspective; and receives from the server 110 a first one-machine video transmitted by the server 110 in response to the first request based on the received video address.
In step 202, playing the panoramic video may be switched to playing the first single-machine-position video.
According to an exemplary embodiment of the present disclosure, a synchronous switching between videos may be performed using a video timestamp drop frame synchronization method or a low-latency transmission protocol. For example, the video stream may include timestamp information (e.g., decoding Time Stamp (DTS) and Presentation Time Stamp (PTS)), and the parsed PTS information may be used for frame dropping to achieve the effect of audio/video synchronization. For another example, a low-latency transmission protocol may be used to perform low-latency processing to achieve low-latency audio and video synchronization.
According to an exemplary embodiment of the present disclosure, the video receiving method may further include: in response to receiving the second switching operation while the first one-player-position video is played, sending a third request for the panoramic video to the server 110, and receiving the panoramic video from the server 110 and terminating receiving the first one-player-position video; and switching to play the first single-machine-position video into a panoramic video, wherein the current playing visual angle of the panoramic video corresponds to the machine-position visual angle of the first single-machine-position video. Here, the second switching operation may refer to an operation of switching from the monoscopic video to the panoramic video, and may include, but is not limited to, gesture zoom, touch back button, and the like. Here, the third request may include a video address of the previously parsed and saved panoramic video. In addition, a video time stamp drop frame synchronization method or a low-latency transmission protocol may be utilized to perform synchronous switching between videos.
According to an exemplary embodiment of the present disclosure, the video receiving method may further include: when playing a video (e.g., a panoramic video or a single-seat video), information of one or more panoramic views or single-seat views is provided. For example, the information may include, but is not limited to, animations, maps, thumbnails or thumbnail videos, etc. regarding the one or more panoramic or single-machine perspectives. The manner of providing may include, but is not limited to, providing the information in a partial area of the current video interface, providing a shortcut button in a partial area of the current video interface, and displaying a folder when a user touches the shortcut button to provide the information.
Alternatively, the one or more panoramic or single-airplane perspectives may be received from the server 110 or determined locally. For example, the one or more panoramic or single-seat perspectives may include all panoramic or single-seat perspectives for the user to conveniently switch any perspective of interest, and/or may include currently popular panoramic or single-seat perspectives (e.g., the most numerous of the perspectives viewed by the full-network users) sent by the server 110 for the user to select the currently more popular perspective, and/or may include the most numerous panoramic or single-seat perspectives viewed by the user himself for the user to conveniently and quickly switch back to the most-desired perspective, and/or other possible panoramic or single-seat perspectives.
Further, in response to receiving a selection operation in the information of the one or more panoramic views or single-machine views, the playing of the panoramic video or the first single-machine view may be switched to the playing of the panoramic video having the selected panoramic view or the single-machine view having the selected single-machine view. Wherein, in addition to the switching of the different view angles of the panoramic video, a fourth request for the panoramic video or the one-machine-position video having the selected one-machine-position view angle is sent to the server 110 and the panoramic video or the one-machine-position video having the selected one-machine-position view angle is received from the server before the switching of the playing panoramic video to the playing one-machine-position video or the switching of the playing one-machine-position video to the playing panoramic video or the other one-machine-position video. In addition, the synchronous switching between videos can be performed using a video time stamp drop frame synchronization method or a low-latency transmission protocol.
In the following, a video receiving method according to an exemplary embodiment of the present disclosure is illustrated by one exemplary example.
When receiving the panoramic video from the server 110, a main view screen of the panoramic video is played by default. When a user performs a view angle switching operation (e.g., rotating a device, gesture sliding, or button clicking, etc.), the main view angle screen may be switched to a second view angle screen after the view angle switching operation. When the user performs the operation of switching the view angle again, the second view angle picture can be switched to a third view angle picture after the operation of switching the view angle. And so on. When a certain view angle picture of the panoramic video is played, a first switching operation of the user is received, a first one-machine-position video having a machine-position view angle corresponding to the current playing view angle of the panoramic video can be requested from the server 110, the first one-machine-position video is received from the server 110, the receiving of the panoramic video is terminated, and the playing of the panoramic video is switched to the playing of the first one-machine-position video. When the first single-machine-position video is played, a second switching operation of the user is received, the panoramic video can be requested from the server 110, the panoramic video is received from the server 110, the receiving of the first single-machine-position video is stopped, the playing of the first single-machine-position video is switched to the playing of the panoramic video, and here, the playing view angle of the switched panoramic video corresponds to the view angle of the first single-machine-position video so as to guarantee synchronous switching. When the panoramic video is being played, the push of the hot stand view angle is received from the server 110, and the received information of the current hot stand view angle may be displayed in a predetermined area in the currently played panoramic video interface. When the user selects this information, the one-machine video having the current hot one-machine view angle may be requested from the server 110, the one-machine video having the current hot one-machine view angle may be received from the server 110 and the receiving of the panoramic video may be terminated, and the playing of the panoramic video may be switched to the playing of the one-machine video having the current hot one-machine view angle.
Fig. 3 is a flowchart illustrating a video transmission method performed by the server 110 according to an exemplary embodiment of the present disclosure.
Referring to fig. 3, in step 301, a first request for a first one-position video of a plurality of one-position videos may be received from a user terminal 120 or 130 while transmitting a panoramic video to the user terminal 120 or 130. Here, the panoramic video and the plurality of single-machine-bit videos are photographed in the same scene. For example, in a shooting scene of the live broadcast room 100 as shown in fig. 1, a panoramic video may be shot by a panoramic camera disposed at the center of a plurality of exhibition halls surrounded all around, and a plurality of booth videos may be shot by a plurality of general cameras for the plurality of exhibition halls disposed with the panoramic camera as a center. In addition, the position view of the first single-position video corresponds to the view of the panoramic video currently played at the user terminal 120 or 130.
According to an exemplary embodiment of the present disclosure, a panoramic video and a plurality of one-seater videos may be acquired before the panoramic video is transmitted to the user terminal 120 or 130. For example, a panoramic video and a plurality of single-position videos may be received from a panoramic camera and a plurality of ordinary cameras.
According to an exemplary embodiment of the present disclosure, after acquiring the panoramic video and the plurality of one-machine-position videos, video information of the plurality of one-machine-position videos may be determined based on the acquired panoramic video and the plurality of one-machine-position videos. For example, a machine-place view angle of each of the plurality of single-machine-place videos may be determined based on main view information included in the panoramic video and machine-place position information of each of the plurality of single-machine-place videos, and a video address may be allocated to each of the plurality of single-machine-place videos. Thus, the video information may include a machine view angle and a video address for each of the plurality of single-machine videos.
According to an example embodiment of the present disclosure, the panoramic video may be transmitted to the user terminal 120 or 130 in response to receiving a second request for the panoramic video from the user terminal 120 or 130.
According to an example embodiment of the present disclosure, upon receiving the second request, video information of the plurality of one-machine videos may be transmitted to the user terminal 120 or 130. For example, video information of a plurality of one-bit videos may be transmitted to the user terminal 120 or 130 at the same time as the panoramic video is transmitted to the user terminal 120 or 130. Alternatively, the video information of the plurality of one-player videos may be provided to the user terminal 120 or 130 during the playing of the panoramic video by the user terminal 120 or 130.
In step 302, a first one-seater video may be transmitted to the user terminal 120 or 130 and the transmission of the panoramic video may be terminated in response to the first request.
According to an example embodiment of the present disclosure, the user terminal 120 or 130 may determine a video address of a first one-seater video having a seater view angle corresponding to a view angle at which the panoramic video is currently played, based on the received video information, and include the video address in the first request. Accordingly, upon receiving the first request, the first one-machine video may be searched from the plurality of one-machine videos based on the video address of the first one-machine video included in the first request, and the searched first one-machine video may be transmitted to the user terminal 120 or 130.
According to an exemplary embodiment of the present disclosure, the video transmission method may further include: in response to receiving a third request for the panoramic video while playing the first one-position video from the user terminal 120 or 130, transmitting the panoramic video to the user terminal 120 or 130, and terminating the transmission of the first one-position video.
According to an exemplary embodiment of the present disclosure, the video transmission method may further include: determining one or more panoramic views or single-machine-position views of the current hot door; a message indicating the determined one or more panorama views or one-machine views is transmitted to the user terminal 120 or 130. For example, the currently hot panoramic view or the single-airplane view may be determined periodically according to the full-network playing situation, and the determined currently hot panoramic view or the determined currently hot single-airplane view may be pushed to the user terminal 120 or 130.
According to an exemplary embodiment of the present disclosure, the video transmission method may further include: in response to receiving a fourth request for the panoramic or single-seat video having the panoramic or single-seat view selected from the information of the one or more panoramic or single-seat views from the user terminal 120 or 130, transmitting the panoramic or single-seat video to the user terminal 120 or 130.
In the following, a video transmission method according to an exemplary embodiment of the present disclosure is illustrated by one exemplary example.
When a panoramic video and a plurality of one-machine videos photographed in the same scene are received from the direct room 100, video information of the plurality of one-machine videos may be generated. When a request for a panoramic video is received from the user terminal 120 or 130, the panoramic video may be transmitted to the user terminal 120 or 130. The video information of the multiple single-machine-location videos shot in the same scene can be sent to the user terminal 120 or 130 while the panoramic video is sent, or the video information of the multiple single-machine-location videos shot in the same scene can be sent to the user terminal 120 or 130 in the process that the received panoramic video is played by the user terminal 120 or 130. When a request for a first one-seater video having a seater angle corresponding to a current play angle of the user terminal 120 or 130 is received from the user terminal 120 or 130, the first one-seater video is transmitted to the user terminal 120 or 130, and the transmission of the panoramic video is terminated. When a request for the panoramic video while the first one-seater video is played is received from the user terminal 120 or 130, the panoramic video is transmitted to the user terminal 120 or 130, and the transmission of the first one-seater video is terminated. Further, the panoramic view or the one-machine view currently being trended may be determined periodically and pushed to the user terminal 120 or 130. When a request for a panoramic or one-seater video having a panoramic view or one-seater view selected from the push is received from the user terminal 120 or 130, the panoramic or corresponding one-seater video is transmitted to the user terminal 120 or 130.
Fig. 4 is a block diagram illustrating a video receiving apparatus 400 according to an exemplary embodiment of the present disclosure.
Referring to fig. 4, the video receiving apparatus 400 may include a transceiving unit 401, a playing unit 402, and a switching unit 403. The transceiving unit 401 communicates with the server 110.
When the playback unit 402 plays the panoramic video, the switching unit 403 may control the transceiver unit 401 to transmit a first request for a first one-bit video of the plurality of one-bit videos to the server 110 in response to the first switching operation being received, and to receive the first one-bit video from the server 110 and terminate receiving the panoramic video. Here, the panoramic video and the plurality of one-machine-position videos are photographed in the same scene, and the machine-position view angle of the first one-machine-position video corresponds to the current play view angle of the panoramic video.
According to an exemplary embodiment of the present disclosure, before the playing unit 402 plays the panoramic video, the transceiving unit 403 may transmit a second request for the panoramic video to the server 110 and receive the panoramic video from the server 110.
According to an exemplary embodiment of the present disclosure, the transceiving unit 401 may receive video information of the plurality of one-bit videos from the server 110 after transmitting the second request.
According to an example embodiment of the present disclosure, the switching unit 403 may determine the first one-machine-digit video from the plurality of one-machine-digit videos based on the video information of the plurality of one-machine-digit videos received from the server 110. For example, the frequency information may include a machine view angle and a video address for each of the plurality of single-machine videos. The switching unit 403 may determine the first one-machine-position video with the first machine-position viewing angle by acquiring the current playing viewing angle of the panoramic video and searching for the first machine-position viewing angle corresponding to the current playing viewing angle of the panoramic video from the machine-position viewing angles of the plurality of one-machine-position videos. Alternatively, the switching unit 403 may determine, as the first machine position angle, a machine position angle at which the difference from the current play angle of the panoramic video is the smallest and the difference is within a predetermined range (e.g., ± 10 °), by calculating differences between the machine position angles of the plurality of single-machine position videos and the current play angle of the panoramic video, respectively.
