Rather, it should be understood that it is provided to more fully understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are used only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

[0016] It should be noted that the title of any section / subsection provided in this specification is not restrictive. In this specification, various embodiments are described in general, and any type of embodiment can be included in any section / subsection. Furthermore, the embodiments described in any section / subsection can be combined with any other embodiments described in the same section / subsection and / or different sections / subsections in any way.

[0020] As briefly described above, users often obtain content they are interested in by watching live streaming playback videos. In conventional live streaming playback generation schemes, usually, when used after the end of a live stream, the live stream video is transcoded by streaming. If the transcoding of the entire live stream video is successful, the playback video is provided to the user for display. Such a conventional live streaming playback generation scheme takes time, has poor timeliness, and cannot meet the user's need to watch the playback as soon as possible.

[0021] Currently, several schemes have been proposed to directly deliver the playback video according to the start time and end time using time-shifted streaming. However, this scheme requires time-shifted streaming using the Adaptive Bitrate Streaming Media Transport Protocol (HLS) format based on the Hypertext Transfer Protocol (HTTP), and has high requirements for compatibility with the player. Also, due to HLS encoding, the loading speed of the playback video in this scheme is slow, the user side cannot open it quickly, and the buffer time to start playback is long. Therefore, this scheme cannot meet the user's need to watch the playback quickly.

[0022] Currently, several live streaming playback generation schemes have been proposed to transcode while live streaming. This scheme simultaneously split-transcodes the content played during the live stream and uploads the request after the end of the live stream. However, there is still transcoding time in such split transcoding, and the transcoding time is determined by the slice length, and playback cannot start immediately after the end of the live stream.

[0023] Embodiments of the present disclosure propose a solution for generating live distribution playback. According to various embodiments of the present disclosure, at a target time (e.g., the first time) during the live distribution period, generation of playback data of the live distribution content from the start time of the live distribution to the target time is started. If the generation of the playback data is completed and an access portal to the playback data is not provided, an access portal to the playback data is provided. If an access portal to the playback data is provided, the playback data is associated with the access portal to replace the previous playback data. If there is a next target time after the target time, generation of the playback data and subsequent replacement of the playback data can be started at the next target time. Thereby, playback data of different lengths can be generated at different times. After these playback data are generated, they can be associated with the access portal so that the user can see them, and the user can quickly view the live distribution playback that has gone online.

[0024] Exemplary embodiments of the present disclosure will be described below with reference to the drawings.

[0025] Example of the environment FIG. 1 shows a schematic diagram of an environmental example 100 in which embodiments of the present disclosure can be realized. In this environmental example 100, the electronic device 110 receives live distribution data 102. The live distribution data 102 may be real-time video live distribution data in any format. As the live distribution continues, the live distribution data 102 is also updated.

[0026] Based on the received live distribution data 102, the electronic device 110 generates a plurality of playback data such as playback data 120-1, playback data 120-2,..., playback data 120-N (N may be any natural number greater than 1). For ease of explanation, in this specification, the playback data 120-1, playback data 120-2,..., playback data 120-N can be collectively or separately referred to as "playback data 120".

[0027] As shown in FIG. 1, the different playback data 120 generated by the electronic device 110 can have different time intervals. These playback data 120 can correspond to live delivery content from the start time of the live delivery to a certain time during the live delivery period. The electronic device 110 can provide a user with an access portal for the playback data 120. The user can view the playback data 120 of the live delivery data 102 through the access portal. The generation process of the playback data 120 will be described later in relation to FIG. 2.

[0028] In some embodiments, the electronic device 110 can be a mobile phone, a desktop computer, a laptop computer, a notebook computer, a netbook computer, a tablet computer, a media computer, a multimedia tablet, a personal communication system (PCS) device, a personal navigation device, a personal digital assistant (PDA), an audio / video player, a digital camera / camera, a positioning device, a television receiver, a radio broadcast receiver, an e-book device, a game device, or accessories and peripheral devices of these devices, or any type of portable terminal, fixed terminal, or portable terminal including any combination thereof. In some embodiments, the terminal device 110 can also support any type of interface for the user, such as a "wearable" circuit.

[0029] In some embodiments, the electronic device 110 can be a server. For example, the electronic device 110 can be various types of computing systems / servers that can provide computing capabilities, including but not limited to mainframes, edge computing nodes, computing devices in a cloud environment, and the like.

[0030] It should be understood that the structure and function of each element within the environment 100 are described for illustrative purposes only and do not imply any limitation regarding the scope of the present disclosure.

[0031] Example of the regenerated data generation process FIG. 2 shows a flowchart of a process 200 for generating live delivery playback data according to some embodiments of the present disclosure. The process 200 can be implemented on the electronic device 110. Next, the process 200 will be described with reference to FIG. 1.

[0032] In block 210, the electronic device 110 activates the generation of playback data related to the live delivery content from the live delivery start time to the target time at the target time during the live delivery. In some embodiments, the target time may be one or more preset time points. For example, the target time may be the first time at a predetermined time interval from the live delivery start time. The target time may be the next target time at a predetermined time interval from the previous target time. According to the predetermined time interval, a plurality of target times can be set during the live delivery. At these target times, the electronic device 110 activates the generation of playback data related to the live delivery content from the live delivery start time to the corresponding target time. That is, the electronic device 110 activates the corresponding playback data generation for each predetermined time interval.

[0033] In some embodiments, the predetermined time interval can be arbitrarily set by the electronic device 110 or by the user. As an example, the predetermined time interval may be 1 minute, 5 minutes, 10 minutes, or other appropriate time intervals.

[0034] In some embodiments, the playback data is generated based on at least a partial transcoding of the corresponding live delivery content. The transcoding method may be arbitrary, such as HLS, Moving Picture Experts Group (MP4), or other appropriate format transcoding.

[0035] Additionally or alternatively, in some embodiments, the playback data is generated based on transmuxing at least a portion of the corresponding live streaming content. As an example, transmuxing can be performed using HTTP-based Dynamic Adaptive Streaming over HTTP (DASH). For example, the electronic device 110 can transmux live streaming content such as in the HLS format from the start time of the live stream to the corresponding target time into playback data (also called vid) in the DASH format at the target time. By using transmuxing to generate the playback data as compared to transcoding, the generation process of the playback data can be accelerated, and the upsampling process of the playback data can be accelerated.

[0036] In such a manner, the playback data of the live streaming content corresponding to different time intervals can be generated at different times. In this way, transmuxing can be performed without interruption during the live stream, and the playback data for each transmuxing can be generated. On the other hand, by using the DASH format, it can be ensured that the playback speed is lower than formats such as MP4 and HLS, and the playback speed on the user side is not higher than that of a normal on-demand video.

[0037] As described above, in the conventional live streaming playback generation scheme, usually, after the live stream ends, time-shifted streaming is used to transcode the live stream video. In this live streaming playback generation scheme, since the entire live stream video is used to generate the playback, the video segment for generating the playback cannot be selected, and the key content cannot be emphasized. Also, in the conventional live streaming transcoding live streaming playback generation scheme, similarly, the video segment for which playback is desired cannot be selected, and the key content cannot be emphasized.

[0038] Embodiments of the present disclosure support the selection of a part of the content in the live distribution content and support the generation of reproduction data of the selected content. Specifically, in some embodiments, the electronic device 110 can determine time constraint information. The time constraint information indicates at least one period that needs to be processed within the period from the live distribution start time to the target time. The electronic device 110 can generate reproduction data corresponding to at least one period.

[0039] When the target time is the first time, the time constraint information can indicate at least one period that needs to be processed within the first period from the live distribution start time to the first time. The electronic device 110 can generate first reproduction data corresponding to at least one period.

[0040] In some embodiments, the time constraint information may be provided by the user. For example, the user can manually set the start time and / or end time of at least one period that requires processing within the first period as the time constraint information. The electronic device 110 can generate corresponding reproduction data based on the start time and / or end time of the period that requires processing manually set by the user. For example, when the user only manually sets the start time, the electronic device 110 can generate corresponding reproduction data based on the start time and the target time. Also, when the user manually sets the start time and the end time, the electronic device 110 can generate corresponding reproduction data based on the start time and the end time.

[0041] Additionally or alternatively, in some embodiments, the time constraint information may be generated by the electronic device 110. For example, at the live distribution start stage and the live distribution end stage, there are usually live distribution segments without actual content for a certain period of time. The electronic device 110 can generate time constraint information to remove the live distribution fragments without actual content.

[0042] By generating playback data based on time constraint information, unnecessary live distribution content can be removed. Also, it is possible to select live distribution segments that need to be generated for playback based on the user's manual settings so that the generated playback data matches the user's needs. In this way, video trimming during live distribution can be supported. The user can trim the live distribution content at any time during live distribution to remove unnecessary content when generating the playback data.

[0043] In some embodiments, the electronic device 110 can associate the trimmed playback data with an access portal. Additionally or alternatively, in some embodiments, the electronic device 110 can associate both untrimmed playback data and trimmed playback data with the access portal to meet different live distribution playback generation requirements.

[0044] In block 220, the electronic device 110 determines whether the generation of the playback data is complete. For example, the electronic device 110 can determine whether the generation of the playback data started at a target time (e.g., the first time or another time) is complete.

[0045] In some embodiments, at block 220, if the electronic device 110 determines that the generation of the playback data is complete, at block 230, the electronic device 110 determines whether an access portal for the playback data is provided. At block 230, if the electronic device 110 determines that the access portal for the playback data is not provided, at block 240, the electronic device 110 provides an access portal for the playback data. For example, assume that the first time is the first time to start generating the playback data. That is, the playback data is not generated and the access portal for the playback data is not provided until the first time. In this case, if the electronic device 110 generates the first playback data corresponding to the first time, the electronic device 110 provides an access portal for the first playback data at block 240.

[0046] At block 250, the electronic device 110 changes the target time to the next target time. As described above, the next target time may be a time with a predetermined time interval from the current target time. In some embodiments, the electronic device 110 can determine whether the live streaming has stopped. If the live streaming has stopped, the electronic device 110 can determine the next target time as the time when the live streaming stopped. If the live streaming has not stopped, the electronic device 110 changes the target time to the next target time with a predetermined time interval from the current target time.

[0047] When the electronic device 110 changes the target time to the next target time at block 250, the electronic device 110 continues to start generating the corresponding playback data at block 210. Taking the second time after setting the target time as the first time as an example, at the second time of the live streaming start time, the electronic device 110 starts generating the second playback data related to the live streaming content from the live streaming start time to the second time at block 210.

[0048] In some embodiments, the electronic device 110 can generate third playback data related to the live streaming content from the first time to the second time. The electronic device 110 can generate second playback data based on the first playback data and the third playback data. In this way, the generation process of the playback data can be simplified.

[0049] Similar to the generation of the playback data described above, the second playback data may be generated based on the transmuxing of at least a part of the corresponding live streaming content. During the generation of the second playback data, the electronic device 110 may select at least one period that needs to be processed among the second period from the live streaming start time to the second time based on the time constraint information. The process of generating the second playback data will not be repeated here.

[0050] When the generation of the second playback data is completed, in block 220, the electronic device 110 determines that the generation of the playback data is completed. The process 200 proceeds to block 230, and in block 230, the electronic device 110 determines that an access portal for the playback data is provided. When the electronic device 110 determines that an access portal for the playback data is provided, the electronic device 110 associates the playback data (e.g., the second playback data) with the access portal in 260 to replace the previous playback data (e.g., the first playback data). In this way, the replacement of the playback data during the live streaming can be supported.

[0051] In some embodiments, after generating the second playback data, the electronic device 110 continues to change the target time to the next target at block 250. In this way, the electronic device 110 may repeat the above-described playback data generation and replacement processes until the live broadcast ends. By continuously replacing the previous playback data with longer playback data, it is possible to store live broadcast content as long as possible in the playback data of the access portal. In this way, it is possible to prevent the loss of the playback content publicly available outside as much as possible. On the other hand, this method can ensure that there is sufficient playback data at the end of the live broadcast to generate the live broadcast playback. The live broadcast playback generated in this way can be connected substantially seamlessly after the end of the live broadcast, improving the user experience.

[0052] In some embodiments, when the live broadcast is on, the electronic device 110 can automatically execute process 200 to generate playback data. Additionally or alternatively, in some embodiments, the electronic device 110 can determine whether to turn on the automatic shelving function. Whether the automatic shelving function is on can be set by the user. If the electronic device 110 determines that the automatic shelving function is on, the electronic device 110 executes process 200. Conversely, if the automatic shelving function is not on, the electronic device 110 may not execute process 200.

[0053] In some embodiments, the embodiments of the present disclosure can also be applied to perform only a single transcoding or transcode process during the live broadcast so that, for example, playback data corresponding to the live broadcast content in a specified time period is correspondingly generated.

[0054] In some embodiments, the electronic device 110 can generate a playback video based on the playback data after the live broadcast ends. Next, the generation process of the playback video will be described in relation to FIGS. 3 and 4.

[0055] Example of the regenerated video generation process Figure 3 shows a flowchart of a process 300 for associating playback data with an access portal after the end of a live stream according to some embodiments of the present disclosure. The process 300 can be implemented on the electronic device 110. Next, with reference to FIG. 1, the process 300 will be described.

[0056] In block 310, the electronic device 110 can determine whether the live stream has ended. If the electronic device 110 determines in block 310 that the live stream has not ended, the electronic device 110 can continue the playback data generation process of process 200 until the live stream ends or the user instructs not to end the playback generation.

[0057] In some embodiments, if the electronic device 110 determines in block 310 that the live stream has ended, the electronic device 110 changes the access permission to the access portal in block 320. For example, the electronic device 110 can make the access portal online on the video platform so that the access portal is changed from internally accessible to publicly accessible. Thus, at this point, the access portal is associated with the latest playback data for which the generation has been completed.

[0058] Alternatively, the electronic device 110 can also make the access portal during the live stream online at an appropriate time so that the public can access it. Thereby, timely access to the playback data for which the generation has been completed can also be obtained during the live stream.

[0059] In some embodiments, at block 330, the electronic device 110 determines whether the generation of the target playback data related to the live distribution content from the live distribution start time to the live distribution end time is completed. At block 330, if the electronic device 110 determines that the generation of the target playback data is not completed, the electronic device 110 continues the target playback data generation process until the generation of the target playback data is completed.

[0060] At block 330, if the electronic device 110 determines that the generation of the target playback data is completed, at block 340, the electronic device 110 can associate the target playback data with the access portal. In this way, the playback data generated at the last target time can be replaced with the target playback data of the live distribution content corresponding to the entire live distribution process. In this way, it is possible to further ensure that there is no content missing in the subsequently generated playback video.

[0061] In some embodiments, when associating the target playback data with the access portal, the electronic device 110 can execute a process 400 for generating a playback video based on the target playback data. In this way, full-range bit transcoding can be performed using the target playback data finally generated after the live distribution ends, and after success, it can be replaced with the final video and shelved.

[0062] FIG. 4 shows a flowchart of a process for generating a playback video based on playback data according to some embodiments of the present disclosure. The process 400 can be implemented on the electronic device 110. Next, the process 400 will be described with reference to FIG. 1.

[0063] In block 410, the electronic device 110 can transcode the target playback data into a first playback video having a first resolution. As an example, the target playback data may be a dash transmuxing data stream having a first resolution (e.g., 1080P). The electronic device 110 can transcode the target playback data into a first playback video in MP4 or other video format having a first resolution (e.g., 1080P).

[0064] In block 420, the electronic device 110 can associate the first playback video with the access portal to replace the target playback data. In some embodiments, in block 430, the electronic device 110 generates a second playback video related to the live delivery content from the live delivery start time to the live delivery end time. The second playback video has a second resolution higher than the first resolution. For example, the second resolution may be 4K resolution. The electronic device 110 can generate the second playback video using currently known or future-developed video conversion methods. The scope of the present disclosure is not limited in this regard.

[0065] In block 440, the electronic device 110 can associate the second playback video with the access portal to replace the first playback video. In this way, a clearer playback video can be provided to the user.

[0066] In some embodiments, in block 450, the electronic device 110 can obtain a clip version of the second playback video. The clip version is generated based on the period held during the live delivery period from the live delivery start time to the live delivery end time. In this way, the content can be trimmed at any time during the live delivery to remove unnecessary live delivery content from the playback video.

[0067] In some embodiments, at block 460, the electronic device 110 generates a set of playback videos corresponding to a set of resolutions based on the clip version. For example, the electronic device 110 can generate a set of playback videos having different resolutions. As another example, the electronic device 110 can generate live streaming content into a plurality of playback videos based on the clip. Each playback video can include key content of the live stream or content that the user pays high attention to. At block 470, the electronic device 110 can associate the set of playback videos with an access portal to replace the second playback video.

[0068] In this way, playback videos with different resolutions can be provided to the user. The user can select the resolution of the video they want to view according to their actual needs, which can improve the user experience. On the other hand, by generating a plurality of playback videos containing different content, the user can selectively view live streaming content segments of interest. These playback videos with different resolutions and different content can meet the needs of different users and improve the user experience.

[0069] Examples of Devices and Apparatuses FIG. 5 shows a schematic configuration block diagram of an apparatus 500 for generating live streaming playback according to an embodiment of the present disclosure. The device 500 can be implemented by or included in the electronic device 110.

[0070] As shown in the figure, the apparatus 500 includes a first playback data generation activation module 510, and the first playback data generation activation module 510 activates the generation of first playback data related to the live delivery content from the live delivery start time to the first time at the first time during the live delivery period. The apparatus 500 further includes an access portal providing module 520, and the access portal providing module 520 provides an access portal for the first playback data in response to the completion of the generation of the first playback data. The apparatus 500 further includes a second playback data generation activation module 530, and the second playback data generation activation module 530 starts the generation of second playback data related to the live delivery content from the live delivery start time to the second time at the second time during the live delivery. The apparatus 500 further includes a playback data replacement module 540, and the playback data replacement module 540 associates the second playback data with the access portal and replaces the first playback data in response to the completion of the generation of the second playback data.

[0071] In some embodiments, an interval of a predetermined time interval is provided between the first time and the second time.

[0072] In some embodiments, the apparatus 500 further includes a time constraint information determination module, and the time constraint information determination module determines time constraint information. The time constraint information indicates at least one period that requires processing within the first period from the live delivery start time to the first time. In some embodiments, the apparatus 500 further includes a first playback data generation module, and the first playback data generation module generates first playback data corresponding to at least one period.
