Description

Technical Field

[0001] The present disclosure relates to the field of live broadcast technology, and in particular to a live broadcast method, device, electronic device, and storage medium. Background Art

[0002] With the rapid development of Internet technology, people can watch, participate in or initiate various types of live broadcasts through live broadcast platforms, such as conference live broadcasts, evening party live broadcasts, and sports event live broadcasts.

[0003] At present, in order to avoid the occurrence of non-compliant live content during live broadcasts, risk control is usually carried out on the live content. For example, the live broadcast signal at the live broadcast site is delayed through live broadcast equipment. When non-compliant live broadcast content is found, the live broadcast signal of this part of the live broadcast content is deleted in advance through the editing function of the live broadcast equipment, thereby skipping the non-compliant live broadcast content.

[0004] However, since the above-mentioned live broadcast equipment is often expensive, professional operators are required to operate the live broadcast signal, and the operation is relatively cumbersome, resulting in high live broadcast costs. Summary of the Invention

[0081] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0082] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.

[0083] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, storage, and display, etc.), and signals involved in this disclosure are all authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the live broadcast and recorded videos involved in the embodiments of this disclosure are all obtained with full authorization.

[0084] Figure 1 Schematic diagram of the implementation environment of a live broadcast method provided by the embodiment of the present disclosure. Figure 1 As shown, the implementation environment includes: a terminal 101 and a server 102. The terminal 101 and the server 102 are directly or indirectly connected via wired or wireless communication, which is not limited.

[0085] Terminal 101 is at least one of a smartphone, a smartwatch, a desktop computer, a laptop computer, a virtual reality terminal, an augmented reality terminal, a wireless terminal, and a portable laptop computer. Terminal 101 may generally refer to one of multiple terminals. The embodiments of this disclosure are illustrated using terminal 101 as an example. Those skilled in the art will appreciate that the number of terminals may be greater or lesser. Illustratively, terminal 101 is capable of installing and running an application that provides a delayed live broadcast function, such as a live broadcast application (also known as a live broadcast platform), a video application, and the like, without limitation.

[0086] The server 102 is an independent physical server, or a server cluster or distributed file system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The number of servers 102 can be more or less, and the embodiments of the present disclosure are not limited to this. Schematically, the server 102 is used to provide background services for applications running on the terminal 101. Schematically, taking the terminal 101 running a live broadcast application and the server 102 providing background services for the live broadcast application as an example, the target object (such as the relevant personnel responsible for the live broadcast) can trigger the terminal to receive the live broadcast signal (i.e., audio and video signal) of the live broadcast site through the live broadcast application, record the live broadcast signal, obtain a live broadcast recorded video, and then delay the live broadcast recorded video through the server 102 to facilitate the audience to watch the live broadcast video of the live broadcast site. Of course, the server 102 can also include other functional servers to provide more comprehensive and diversified services, which is not limited to this.

[0087] Based on the above implementation environment, the live broadcast method provided by the embodiment of the present disclosure is introduced below.

[0088] Figure 2 This is a flow chart of a live broadcast method provided by an embodiment of the present disclosure. Figure 2 As shown, the live broadcast method is executed by the terminal and includes the following steps 201 to 204.

[0089] In step 201, the terminal plays the non-live video of the live recorded video, where the non-live video includes a video segment of the live recorded video that is not delayed for live broadcast.

[0090] In the disclosed embodiment, live recorded video refers to a video obtained by recording a live signal (i.e., an audio and video signal) at a live broadcast site. For example, the live broadcast site is a concert site, a conference site, a party site, a sports event site, etc., and this is not limited to this. Schematically, the terminal installs and runs a target application that provides a delayed live broadcast function. Relevant personnel can use the target application to delay the live recorded video for live broadcast. Accordingly, the terminal plays the non-live broadcast video on the application interface of the target application for relevant personnel to view. It should be understood that the delay duration of the delayed live broadcast based on the live recorded video by the terminal can be set according to demand, and this is not limited to this. For example, taking a delay duration of 5 minutes as an example, when the real time at the live broadcast site is 18:05, after the delayed live broadcast, the real time of the currently playing segment of the live video is 18:00, and the non-live broadcast video includes video segments with real times between 18:00 and 18:05, that is, video segments in the live recorded video that are not delayed for live broadcast.

[0091] In step 202, the terminal displays an editing track for the non-live video.

[0092] In an embodiment of the present disclosure, the editing track is used to edit video clips in a non-live video. Schematically, the terminal displays the editing track for the non-live video on the application interface of the target application. For example, the terminal displays the editing track below the playback area of the non-live video on the application interface, and this is not limited to this. It should be noted that the terminal can synchronously display the editing track for the non-live video when playing live video and non-live video; it can also display the editing track in response to a triggering operation on the video editing control on the application interface when playing live video and non-live video, and this is not limited to this.

[0093] In step 203, the terminal generates an edited non-live video in response to an editing operation on a target video segment on the editing track, where the target video segment refers to a video segment that meets the live content filtering condition.

[0094] In the embodiment of the present disclosure, editing operations include deletion, replacement, and volume editing, etc. These editing operations will be performed in the subsequent Figure 3 The live content filtering condition refers to the content of the live video that does not meet the live broadcast requirements, or is non-compliant, including sound content and image content. For example, if the sound content of a video clip includes sensitive words, or the image content includes sensitive images, then the video clip meets the live content filtering condition. It should be understood that the specific form of the live content filtering condition can be set according to actual needs and is not limited to this.

[0095] In step 204, the terminal performs delayed live broadcast based on the edited non-live video.

[0096] In the disclosed embodiment, after editing the target video clip that meets the live content filtering conditions, delayed live broadcast is performed based on the edited non-live video, so that the live video finally broadcast meets the live broadcast requirements, ensuring the security of the live content.

[0097] In summary, the live broadcast method provided by the disclosed embodiments allows relevant personnel to promptly identify target video segments in the non-live videos that meet the live content filtering criteria by playing the non-live videos. Furthermore, by displaying an editing track for the non-live videos, relevant personnel can promptly edit the target video segments, thereby performing delayed live broadcast based on the edited non-live videos. In this way, a lightweight live broadcast method is provided that can effectively improve human-computer interaction efficiency and significantly reduce live broadcast costs while ensuring the compliance of live broadcast content.

[0098] above Figure 2 The following describes the brief process of the live broadcast method provided by the embodiment of the present disclosure. Figure 3 The embodiment shown is used to introduce the live broadcast method in detail.

[0099] Figure 3 This is a flow chart of another live broadcast method provided by an embodiment of the present disclosure. Figure 3 As shown, the live broadcast method is executed by the terminal and includes the following steps 301 to 306.

[0100] In step 301, the terminal records the received live broadcast signal of the live broadcast site to obtain a live broadcast recording video.

[0101] In the disclosed embodiments, a terminal is connected to a live broadcast device at a live broadcast site via a wired or wireless communication method. The live broadcast signal from the live broadcast site is transmitted by the live broadcast device, which may be, for example, a director's station device, without limitation. Illustratively, the terminal installs and runs a target application that provides a delayed live broadcast function. A target user (e.g., a person responsible for the live broadcast) can use the target application to trigger the terminal to record the live broadcast signal received from the live broadcast site to obtain a live broadcast video.

[0102] In some embodiments, the terminal is equipped with an acquisition card (a capture device that captures external photoelectric, video, audio and other analog signals and digitizes them into a computer for digital processing, including image acquisition cards, video acquisition cards, audio acquisition cards, etc.), and the live broadcast device processes the real-time signal (i.e., audio and video signal) of the live broadcast site to obtain the program video signal (Program, PGM) of the live broadcast site, also known as the program bus, and sends the PGM signal of the live broadcast site to the terminal through the digital component serial interface (Serial Digital Interface, SDI) interface. The terminal records the PGM signal of the live broadcast site through the acquisition card to obtain a live recorded video. It should be understood that the process of the terminal recording the live broadcast signal is also the process of storing the live broadcast signal of the live broadcast site.

[0103] In step 302, the terminal performs delayed live broadcasting of the live recorded video to obtain a live video.

[0104] In an embodiment of the present disclosure, a terminal and a server are connected via a wired or wireless communication method, and the server is used to provide background services for the target application running on the terminal. Schematically, the terminal responds to a delayed live broadcast operation on the live recorded video, generates a live video based on the delay duration corresponding to the delayed live broadcast operation, and sends the live video to the server (i.e., live streaming), thereby achieving delayed live broadcast. The delay duration can be set as needed and will not be further described here.

[0105] In step 303, the terminal plays the live recorded video, the live video, and the non-live video.

[0106] In the disclosed embodiment, the video clip of the non-live broadcast video follows the currently playing segment of the live broadcast video. The terminal plays the live broadcast recorded video, live video, and non-live broadcast video on the application interface of the target application. By playing these types of videos simultaneously on the application interface, relevant personnel can clearly see the real-time video of the live broadcast site, the live video that has been broadcast, and the non-live video that has not yet been broadcast, thereby improving the efficiency of human-computer interaction and enhancing the user experience.

[0107] In step 304, the terminal displays an editing track for the non-live video.

[0108] In the embodiment of the present disclosure, this step 304 is similar to the above Figure 2 The same is true for step 202 in the illustrated embodiment, so it will not be described in detail.

[0109] In some embodiments, the terminal also displays the recording track of the live recorded video and the broadcast track of the live video. By displaying the recording track and the broadcast track, it is convenient for relevant personnel to clearly understand the difference between the live recording situation and the live broadcast situation, thereby improving the efficiency of human-computer interaction. It should be noted that the broadcast track of the live video and the editing track of the non-live video can be displayed based on the same track or separately, without limitation. For example, refer to Figure 4 , Figure 4 This is a schematic diagram of an application interface provided by an embodiment of the present disclosure, taking the broadcast track of a live video and the editing track of a non-live video as an example, Figure 4 As shown, the terminal plays live recorded video (i.e., real-time signal), live video (i.e., broadcast signal), and non-live video (i.e., editable signal) in the playback area 401 of the application interface 400, and displays the recording track and target track of the live recorded video in the editing area 402. The target track includes the broadcast track of the live video and the edit track of the non-live video (also known as the broadcast + edit track). In the target track, the video clips before the broadcast timeline belong to the live video, and the video clips after the broadcast timeline belong to the non-live video.

[0110] It should be understood that during the delayed live broadcast process, the above steps 301 to 304 are executed synchronously, that is, when the terminal receives the live broadcast signal, it records the live broadcast video and performs delayed live broadcast, and synchronously plays the live broadcast video, live video and non-live broadcast video on the application interface, and displays the editing track for the non-live broadcast video, so that relevant personnel can clearly see the entire delayed live broadcast situation, so that when the target video clip that meets the live content filtering conditions appears in the non-live broadcast video, the relevant personnel can edit the target video clip in time, so that the edited non-live broadcast video meets the requirements of the live broadcast. The editing process of the target video clip is introduced in detail through step 305 below.

[0111] In step 305, the terminal generates an edited non-live video in response to an editing operation on a target video segment on the editing track, where the target video segment refers to a video segment that meets the live content filtering condition.

[0112] In the disclosed embodiment, the target video segment includes at least one video frame. Illustratively, in response to an edit operation on at least one video frame in the target video segment, the terminal edits the at least one video frame to generate an edited, non-live video. This approach enables real-time editing on a frame-by-frame basis, improving the accuracy of video editing. Furthermore, as can be seen from the aforementioned step 203, editing operations include deletion, replacement, volume editing, and so on. These editing operations are described below.

[0113] The first one is the delete operation.

[0114] In some embodiments, the terminal displays multiple editing options in response to the positioning operation of the target video clip on the editing track, and deletes the target video clip in response to the triggering operation of the deletion option in the multiple editing options, thereby obtaining the edited non-live video. For example, referring to Figure 5 , Figure 5 Schematic diagram of an editing operation provided by an embodiment of the present disclosure. Figure 5 As shown, the terminal displays the editing track of the non-live video in the editing area 402 of the application interface 400. In response to the positioning operation of the target video clip 501, the terminal displays multiple editing options 502. In response to the triggering operation of the "Delete" option among the multiple editing options, the target video clip 501 is deleted to obtain the edited non-live video.

[0115] Through the above method, for the video clips that meet the live content filtering conditions, the terminal can respond to the deletion operation and directly delete the corresponding video clips, which effectively improves the video editing efficiency.

[0116] The second type is the replacement operation.

[0117] Schematically, in response to a replacement operation on a target video clip on an editing track, the terminal displays multiple video clip materials; in response to a selection operation on a target video clip material among the multiple video clip materials, the target video clip is replaced with the target video clip material to obtain an edited non-live video.

[0118] In some embodiments, based on the same process as the first deletion operation described above, the terminal displays multiple editing options in response to the positioning operation of the target video clip, and displays multiple video clip materials in response to the triggering operation of the replacement option in the multiple editing options, so as to replace the target video clip with the target video clip material. Figure 6 , Figure 6 Schematic diagram of another editing operation provided by the embodiment of the present disclosure. Figure 6 As shown, the terminal displays the editing track of the non-live video in the editing area 402 of the application interface 400. In response to the positioning operation of the target video clip 501, the terminal displays multiple editing options 502. In response to the triggering operation of the "Replace" option in the multiple editing options, the terminal displays multiple video clip materials 600. In response to the selection operation of the video clip material A, the target video clip is replaced with the video clip material A to obtain the edited non-live video.

[0119] In some embodiments, the matching degree between the plurality of video clip materials and the scene of the non-live video meets the target condition. Schematically, the process of displaying the plurality of video clip materials on the terminal includes the following steps:

[0120] Step A1, the terminal performs scene recognition on the non-live video in response to the replacement operation, and obtains the scene information of the non-live video. Among them, the terminal calls the first artificial intelligence model in response to the replacement operation, performs scene recognition on the non-live video, and obtains the scene information of the non-live video. For example, the scene information indicates that the live broadcast site is a conference site. Of course, the terminal can also perform scene recognition on the live recorded video in advance, so as to directly obtain the scene information in response to the replacement operation. Alternatively, the terminal can also obtain the scene information based on the live broadcast tag information. For example, before the live broadcast, the relevant personnel input the live broadcast tag information of the live broadcast (such as the live broadcast of a sports event) through the target application, and the terminal can obtain the scene information based on the live broadcast tag information. The embodiment of the present disclosure does not limit the method for determining the scene information.

[0121] In step A2, based on the scene information, the terminal determines from the video clip material library multiple video clip materials that match the scene information. The video clip material library stores material tag information for each video clip material. The terminal uses the scene information as an index to search the video clip material library for material tag information that matches the scene information, thereby obtaining multiple video clip materials that match the scene information. For example, if the scene information indicates that the live broadcast is a sports event, then the multiple video clip materials are all materials related to the sports event; if the scene information indicates that the live broadcast is a gala, then the multiple video clip materials are all materials related to performances, and so on. This is not limited in the present embodiment.

[0122] Step A3: The terminal displays the multiple video clip materials based on the matching degree between the scene information and each video clip material. The terminal determines the matching degree between the scene information and each video clip material based on the material tag information of the scene information and displays the multiple video clip materials in descending order of matching degree.

[0123] Through the above steps A1 to A3, when editing the target video clip based on the replacement operation, the terminal displays the video clip material that matches the scene information of the non-live video, so that the replaced video clip has a high degree of adaptability with the non-live video, thereby avoiding the content of the replaced video clip being too abrupt. Moreover, considering that relevant personnel are likely to choose video clip materials that have a high degree of adaptability with the non-live video, the above method can improve the efficiency of human-computer interaction, thereby enhancing the user experience.

[0124] The third type is volume editing operation.

[0125] Schematically, when the sound content of the target video clip meets the live content filtering conditions, the terminal displays the volume editing track in response to the volume editing operation of the target video clip on the editing track; in response to the editing operation on the volume editing track, the volume of the target video clip is edited to obtain the edited non-live video.

[0126] In some embodiments, based on the same process as the first deletion operation described above, the terminal displays multiple editing options in response to the positioning operation of the target video clip, and displays a volume editing track in response to the triggering operation of the volume editing option among the multiple editing options, so as to edit the volume of the target video clip. Figure 7 , Figure 7 Schematic diagram of another editing operation provided by the embodiment of the present disclosure. Figure 7 As shown, the terminal displays the editing track of the non-live video in the editing area 402 of the application interface 400. In response to the positioning operation of the target video clip 501, the terminal displays multiple editing options 502. In response to the triggering operation of the "volume editing option" among the multiple editing options, the volume editing track 700 (also called the mixing console) is displayed. In response to the editing operation of the volume editing track 700, the volume of the target video clip 501 is edited (such as muting, etc.) to obtain the edited non-live video.

[0127] It should be noted that in the above process, the volume editing track is displayed by the terminal in response to the volume editing operation. In other embodiments, the volume editing track is always displayed on the application interface, that is, the terminal responds to the positioning operation of the target video clip on the editing track, displays the volume of the target video clip on the volume editing track, and responds to the editing operation of the volume editing track, and edits the volume of the target video clip to obtain the edited non-live video. The embodiments of the present disclosure are not limited to this.

[0128] In the above manner, for a video clip whose sound content meets the live content filtering conditions, the terminal can edit the volume of the video clip based on the volume editing operation to ensure the security of the live content.

[0129] In addition, the above introduction to editing operations is only a few schematic illustrations provided by the embodiments of the present disclosure. In some embodiments, the terminal can also provide other forms of editing operations. For example, when part of the image content of the target video clip meets the live content filtering conditions, the terminal provides an area blocking operation, that is, the target object blocks part of the target video clip by implementing the area blocking operation, such as adding stickers, mosaics, etc., and there is no limitation on this.

[0130] After the above step 305, when a target video segment that meets the live content filtering conditions appears in the non-live video, the terminal can respond to the editing operation on the target video segment and edit the target video segment in time, so that the edited non-live video meets the live broadcast requirements, thereby ensuring the security of the live content.

[0131] In step 306, the terminal performs delayed live broadcast based on the edited non-live video.

[0132] In the embodiment of the present disclosure, the terminal sends the edited non-live video to the server to achieve delayed live broadcast.

[0133] Reference below Figure 8 , the above steps 301 to 306 are schematically illustrated. Figure 8 Schematic diagram of a live broadcast method provided by an embodiment of the present disclosure. Figure 8 As shown, the live broadcast method includes: the director station equipment processes the real-time signal of the live broadcast site to obtain a PGM signal, sends the PGM signal to the terminal through the SDI interface, the target application running on the terminal records the PGM signal to obtain a live recorded video, delays the live recorded video, plays the live recorded video, the live video and the non-live video, edits the target video clips in the non-live video that meet the live content filtering conditions through the editing track to obtain the edited non-live video, and pushes the PGM signal of the edited non-live video for live broadcast, that is, sends it to the server, and the server implements delayed live broadcast to reach the audience.

[0134] In summary, the live broadcast method provided by the disclosed embodiments allows relevant personnel to promptly identify target video segments in the non-live videos that meet the live content filtering criteria by playing the non-live videos. Furthermore, by displaying an editing track for the non-live videos, relevant personnel can promptly edit the target video segments, thereby performing delayed live broadcast based on the edited non-live videos. In this way, a lightweight live broadcast method is provided that can effectively improve human-computer interaction efficiency and significantly reduce live broadcast costs while ensuring the compliance of live broadcast content.

[0135] In the above Figures 2 to 8 In the illustrated embodiment, the target video clip can be understood as being observed by a user during the terminal's playback of a non-live video. In other embodiments, the terminal can incorporate an artificial intelligence model to automatically identify video clips within the non-live video that meet the live content filtering criteria, thereby assisting the user, further improving human-computer interaction efficiency, and enhancing the efficiency of editing the target video clip. This process is described below.

[0136] Schematically, the terminal performs content recognition on the non-live video, and when it is recognized that there is a target video segment in the non-live video, based on the position of the target video segment on the editing track, displays a prompt message, which indicates that the content of the target video segment meets the live content filtering condition. The terminal calls the second artificial intelligence model to perform content recognition on the non-live video, and when it is recognized that the target video segment exists in the non-live video, displays a prompt message based on the recognition result of the target video segment. For example, referring to Figure 9 , Figure 9 Schematic diagram of a display prompt message provided by an embodiment of the present disclosure. Figure 9 As shown, the terminal displays the editing track of the non-live video in the editing area 402 of the application interface 400. When the target video clip is identified, based on the position of the target video clip on the editing track, a prompt message 900 is displayed, such as "The above video clip contains XXX sensitive words" or "The above video clip contains XXX sensitive images", etc., which are not limited to this. In this way, the terminal can automatically identify video clips in the non-live video that meet the live content filtering conditions, and when identified, display a prompt message at the corresponding position to prompt relevant personnel, thereby improving the efficiency of human-computer interaction.

[0137] In some embodiments, the terminal can also display target options for editing the target video clip based on the recognition result of the target video clip to achieve automatic editing. Schematically, this process includes: the terminal displays the target option based on the position of the target video clip on the editing track, and the target option indicates to perform target editing on the target video clip to obtain the edited non-live video; accordingly, the aforementioned process of "generating the edited non-live video in response to the editing operation of the target video clip on the editing track" includes: in response to the confirmation operation of the target option, perform target editing on the target video clip to obtain the edited non-live video. Among them, the terminal determines the target editing for the target video clip based on the recognition result of the target video clip, and displays the target option based on the position of the target video clip on the editing track so that relevant personnel can confirm the operation. For example, refer to Figure 10 , Figure 10 is a schematic diagram of a display target option provided by an embodiment of the present disclosure, such as Figure 10As shown, the terminal displays the editing track of the non-live video in the editing area 402 of the application interface 400. When the target video clip is identified, based on the position of the target video clip on the editing track, a prompt message "The above video clip contains XXX sensitive images" and a target option "Please confirm whether to delete" are displayed. In response to the confirmation operation of the target option, the target video clip 501 is deleted to obtain the edited non-live video. In this way, the terminal can provide an automatic editing function for the identified target video clip. By displaying the target option, it is convenient for relevant personnel to confirm whether to perform the target editing, so as to improve the efficiency of human-computer interaction and enhance the user experience. Of course, if the relevant personnel implements a cancel operation on the target option, the terminal can respond to other editing operations on the target video clip to implement the editing of the target video clip (that is, the aforementioned Figure 3 Step 305 in the illustrated embodiment.

[0138] It should be noted that the above Figure 9 and Figure 10 The illustration is merely an example. In some embodiments, the terminal may also display other forms of prompt messages and target options. Furthermore, the number of target video clips may be one or more, which is not limited in the embodiments of the present disclosure.
