Each display device in the virtual auditorium plays the target video in this way, so that the difference between the playing schedules of the display devices can be reduced.
Fig. 7 is a flowchart of a video playing method according to an embodiment of the present application. The method may be applied to the video playing system shown in fig. 1, where the video playing system includes a first display device and a second display device, the number of the second display devices may be one or more, and the target display device in this embodiment may be any one of the first display device and the second display device. As shown in fig. 7, the method may include:
step 701, the first display device sends a request for creating a auditorium to the server, where the request for creating the auditorium carries an identifier of the target video.
Alternatively, the first display device may send a theater creation request to the server upon acquiring the creation instruction. Optionally, the auditorium creation request may carry an identification of the target video and an identification of the second display device.
When a user of a first display device needs to invite a user of a second display device to synchronously watch a target video, the first display device may be triggered to initiate the creation of a virtual auditorium. For example, a user of a first display device may select or enter an identification of a target video and an identification of a second display device on the first display device and trigger the first display device to generate a auditorium creation request for instructing a server to create an auditorium service based on the identification of the target video and the identification of the second display device. Thereafter, the user may operate the first display device to generate a creation instruction, and upon generation of the creation instruction, send an auditorium creation request to the server through a communication connection with the server. Alternatively, the user may select only the identifier of one second display device, or may select the identifiers of a plurality of second display devices. Optionally, the number of identifiers of the second display device selected by the user may or may not have an upper limit (e.g., 5, 6, or other values).
For example, when a user needs to create a virtual auditorium, the user may trigger the first display device to start the auditorium function, and the first display device may present a creation interface on which the user may select the identifier of the target video and the identifier of the second display device. Fig. 8 is a schematic diagram of a creation interface provided by an embodiment of the present application, and as shown in fig. 8, the creation interface 810 includes an addition control 811, an invitation control 812, a creation control 813, and a cancellation control 814. The user may click the add control 811 to trigger the first display device to determine the identity of the target video and the user may click the invite control 812 to trigger the first display device to determine the identity of the second display device. Thereafter, the user may click on the create control 813 to trigger the first display device to generate a create instruction, or the user may click on the cancel control 814 to cancel the creation of the virtual auditorium. Optionally, when the first display device is an intelligent television, the user may click a control in the creation interface through a remote controller or another control device connected to the first display device.
Optionally, the process of the first display device determining the identity of the target video may include: after the user clicks the add control 811, the first display device displays a candidate video interface including an identification of at least one candidate video (e.g., a video name or a poster of the video, etc.). The user may select an identifier of any one of the identifiers of the at least one candidate video, and the first display device may determine the identifier of the candidate video selected by the user as the identifier of the target video, and determine the candidate video indicated by the identifier of the candidate video as the target video. The first display device may also display an identification of the target video at the location where the control 811 is added in the creation interface.
Optionally, the first display device may be logged with a social account of the user, and the social account may be a user identifier of the first display device. The process of the first display device determining the identity of the second display device may comprise: after the user clicks the invitation control 812, the first display device displays a friend list corresponding to the social account of the user, where the friend list includes at least one candidate account. The user may select any one or more candidate accounts of the at least one candidate account, and the first display device may determine, as the second display device, all the display devices logged in with the candidate accounts, and determine an identifier of the second display device. The first display device may also display an identification of the second display device at a location in the creation interface where the invitation control 812 is located, such as displaying a selected candidate account or a label of the candidate account (e.g., a user avatar).
The identification of the display device may comprise a device identification or a user identification of the display device. For example, the device identifier of the second display device may include a unique identifier that is set when the second display device is shipped from a factory, and the user identifier of the second display device may include a user account (e.g., a social account of the user) logged in on the second display device. For example, in this embodiment of the application, the first display device may directly use the candidate account selected by the user as the identifier of the second display device, where the identifier is the user identifier of the second display device.
Optionally, as shown in FIG. 8, the creation interface may also include the name "XX auditorium" of the auditorium, which may be customized by the user of the first display device and may be changed by the user at any time.
Alternatively, the controller of the first display device may generate a auditorium creation request in step 701, and then transmit the auditorium creation request to the server through the communication interface.
Step 702, the server creates a auditorium service according to the auditorium creation request.
After receiving the auditorium creation request sent by the first display device, the server may create an auditorium service according to the identifier of the target video carried by the auditorium creation request. Optionally, the server may further generate a binding relationship between the identifier of the first display device and the identifier of the auditorium service, and according to the binding relationship, the server may determine that the first display device is a display device accessing the auditorium service, that is, a display device in the virtual auditorium corresponding to the auditorium service. The respective display devices accessing the auditorium service may be used to play the target video corresponding to the auditorium service synchronously.
Step 703, the server sends the identifier of the auditorium service and the target video to the first display device.
The server can also allocate identifiers for the auditorium services after the auditorium services are created so as to distinguish the auditorium services in the server, wherein different auditorium services correspond to different identifiers. Alternatively, the identification of the auditorium service may be a string of characters randomly assigned by the server, or a number of the auditorium service ordered by the time of creation.
Optionally, the auditorium creation request sent by the first display device may further carry an identifier of the first display device, and after the auditorium service is created, the server may return the identifier of the auditorium service and the target video to the first display device according to the identifier of the first display device. Alternatively, the server may directly transmit the target video to the first display device, or the server may also send a storage address of the target video to the first display device to instruct the first display device to acquire the target video according to the storage address.
Optionally, in step 702, the server may send the identifier of the auditorium service and the target video to the communication interface of the first display device, and the controller of the first display device may obtain the identifier of the auditorium service and the target video received by the communication interface.
Step 704, the server sends invitation information to the second display device according to the auditorium creation request, wherein the invitation information carries the identification of the auditorium service.
After receiving the auditorium creation request sent by the first display device and allocating the identifier for the auditorium service, the server may send invitation information carrying the identifier of the auditorium service to the second display device according to the identifier of the second display device carried in the auditorium creation request. Optionally, the invitation information may also carry an identification of the auditorium service, an identification of the first display device and an identification of the target video. The invitation information is used to invite the second display device to access the auditorium service to play the target video with the first display device.
Alternatively, the invitation information may be a prompt, invitation code or link, etc. The server sends the invitation information to the second display device, and then the second display device receives the invitation information, and the display screen of the second display device can display the invitation information.
Exemplarily, fig. 9 is a schematic diagram of a display interface of a second display device provided in an embodiment of the present application. As shown in fig. 9, the invitation message is a prompt message, and the prompt message may be "do you invite you to join the auditorium XX to watch video xxx, please click the lower option to confirm whether to accept? "where" xiao ming "may be the user identification of the first display device," auditorium XX "may be the identification of the auditorium service, and" video xxx "may be the identification of the target video, such as the name of the target video. For another example, if the invitation information is an invitation code, the second display device may query information of a corresponding auditorium service according to the invitation code, and then determine whether to access the auditorium service. As another example, if the invitation information is a link, the user may directly click on the link to cause the second display device to display information of the auditorium service. The information of the auditorium service may include: the request server creates an identification of the display information of the auditorium service (e.g. an identification of the first display device), an identification of the video corresponding to the auditorium service (e.g. the target video).
Optionally, in step 704, the server may send the invitation information to a communication interface of the second display device, and the controller of the second display device may control the display screen to display the invitation information according to the invitation information.
Step 705, the second display device sends a auditorium access request to the server, where the auditorium access request carries an identification of the auditorium service.
Optionally, the auditorium access request may carry an identification of the auditorium service and an identification of the second display device.
For example, after viewing the invitation information displayed by the second display device, the user may operate the second display device to trigger the second display device to generate an auditorium access request, which is then sent to the server. With continued reference to fig. 9, the second display device may also display selection buttons when displaying the invitation information, such as the selection buttons may include an "accept" button and a "cancel" button. When the user clicks the "accept" button, the second display device may determine that a trigger operation to generate an auditorium access request is detected, generate an auditorium access request, and send the auditorium access request to the server. Optionally, the user of the second display device may also click a "cancel" button, at which time the second display device may stop displaying the invitation information and resume displaying the original interface.
Optionally, the controller of the second display device may generate the auditorium access request in step 705 and send the auditorium access request to the server via the communication interface.
Step 706, the server sends the target video to the second display device according to the auditorium access request.
After receiving the auditorium access request sent by the second display device, the server may determine the target video corresponding to the auditorium service according to the identifier of the auditorium service carried by the auditorium access request, and further send the target video to the second display device. The manner in which the server sends the target video to the second display device may refer to the record related to the server sending the target video to the first display device in step 703, which is not described in detail in this embodiment of the present application.
Optionally, the server may send, to the second display device, a part of the target video after the current playing progress of the first display device according to the playing progress of the first display device on the target video, or the server may send, to the second display device, a part of the target video after the theoretical playing progress, so as to ensure that a difference between the playing progresses of the first display device and the second display device is small. For example, if the second display device sends a request for accessing the auditorium to the server at a first time, and the first display device plays to the 20 th minute in the target video at this time, that is, the playing progress of the first display device is the 20 th minute, the server may send the portion of the target video after the 20 th minute to the second display device.
It should be noted that, in this embodiment, the server sends the target video to the first server after the auditorium service is created, and sends the target video after the current playing progress of the first display device in the target video to the second display device after receiving the auditorium access request sent by the second display device. Optionally, the server may also wait for receiving a theater access request sent by the second display device, and then send the target video to the first display device and the second display device at the same time, so as to ensure that a difference between the playing schedules of the first display device and the second display device is small, and enable a user of the second display device to view the complete target video.
Alternatively, when the video playback system includes a plurality of second display devices, the server may transmit the target video to the first display device and all of the second display devices after receiving the auditorium access request transmitted by all of the second display devices. Alternatively, the server may transmit the target video to the first display device and the part of the second display devices after receiving the auditorium access request transmitted by the part of the second display devices; after receiving the auditorium access request sent by the remaining part of the second display devices, sending the part (or the part after the playing progress of any display device in the virtual auditorium) after the theoretical playing progress in the target video to the remaining part of the second display devices.
Optionally, when the server receives a theater access request of the second display device for the theater service, the server may further generate a binding relationship between the identifier of the second display device and the identifier of the theater service, and according to the binding relationship, the server may add the second display device to the virtual theater corresponding to the theater service, and further send the target video to the second display device.
Optionally, in step 706, the controller of the second display device may receive the target video sent by the server through the communication interface.
In step 707, the first display device plays the received portion of the target video at the first play speed during the process of receiving the target video.
The server sequentially sends the frame images in the target video and the audio corresponding to the frame images to the first display device according to the display sequence of the frame images in the target video. After receiving at least a portion of the target video, the first display device may begin playing the received portion of the target video and may play the received portion at a default first play speed. Illustratively, the first play speed may be a speed at which 24 frames of images are played per second. The first playing speed may also be other customized playing speeds, such as a speed of playing 26 frames or 30 frames of images per second, which is not limited in the embodiment of the present application.
Optionally, in step 707, the controller of the first display device may control the display screen of the first display device to play the received portion of the target video at the first play speed during the receiving of the target video through the communication interface.
Step 708, the first display device determines a first absolute value of a time difference between a first playing progress of the target video and the theoretical playing progress.
It should be noted that, in order to distinguish the playing schedules of the target video on the first display device and the second display device, in the embodiment of the present application, the playing schedule of the target video on the first display device is referred to as a first playing schedule, an absolute value of a time difference between the first playing schedule and the theoretical playing schedule is referred to as a first absolute value, the playing schedule of the target video on the second display device is referred to as a second playing schedule, and an absolute value of a time difference between the second playing schedule and the theoretical playing schedule is referred to as a second absolute value.
Optionally, the first display device may determine the current playing progress every other fixed time, and further determine a first absolute value of a time difference between the current playing progress and the theoretical playing progress. Optionally, the interval duration of the first absolute value determined twice by the first display device may also be different, and the embodiment of the present application is not limited.
In some embodiments, the server sends the theoretical playing progress to a plurality of display devices accessing the service of the auditorium, and the plurality of display devices adjust the playing progress of the plurality of display devices according to the same theoretical playing progress.
In some embodiments, the theoretical play progress is: and when all the target videos are acquired, the progress of playing the target videos at the first playing speed is obtained by the first display device which is used for receiving the target videos in the multiple display devices for synchronously playing the target videos. The first display device to receive the target video may be the first display device to send the auditorium creation request to the server.
In some embodiments, the theoretical play progress is: after the target video service is started, the server increases the theoretical playing progress along with the increase of the starting time of the target video service according to the value determined by the starting time point of the target video service. The target video service may be the auditorium service.
Illustratively, the first display device may determine the theoretical playing progress through the following three alternative implementations:
in a first implementation manner, the first display device may determine a theoretical playing progress of the target video according to a starting playing time of the target video on the first display device and the first playing speed. If the first playing speed is a standard one-time playing speed, the first display device may determine a time difference between the current time and the starting playing time as a theoretical playing progress of the target video. For example, if the first display device determines that the starting playing time of the target video is 8:00, the first display device may determine that the theoretical playing progress of the target video at 8:01 is the first minute of the target video, that is, the content of the first minute of the target video should be played at 8:01 theoretically. Optionally, if the first playing speed is not a standard double-speed playing speed, if the first playing speed is a double-speed playing speed, the first display device may determine that twice the time difference between the current time and the starting playing time is a theoretical playing progress of the target video. In this way, theoretical playing speeds for other first playing speeds can be obtained, and the embodiments of the present application are not described again.
In a second implementation manner, the server may record the creation completion time of the auditorium service, and the first display device may also determine the theoretical playing progress of the target video according to the creation completion time and the first playing speed. Compared with the first implementation manner, the implementation manner is only to change the starting playing time of the target video on the first display device to the creation completion time of the auditorium service, and the specific manner of determining the theoretical playing progress is the same as the first implementation manner, and is not described again in this embodiment of the application.
In a third implementation manner, the first display device may also determine the playing progress of any second display device as a theoretical playing progress; or the first display device may also directly determine the playing progress of the first display device as the theoretical playing progress.
Alternatively, step 708 may be performed by a controller in the first display device.
And step 709, when the first absolute value is greater than the first time length, the first display device adjusts a first playing progress of the target video.
The first display device may adjust the first playing progress of the target video once only by determining that the first absolute value is greater than the first duration until the first absolute value is less than or equal to the first duration. Optionally, the first display device may directly make the first absolute value less than or equal to the first duration by performing one-time play progress adjustment; or, the adjustment of the one-time playing progress may not directly make the first absolute value smaller than or equal to the first duration, and at this time, the first display device may continue to adjust the first playing progress after determining the first absolute value next time.
Alternatively, the first duration may be positively correlated with the time interval during which the first display device determines the first absolute value. Since the probability that the difference occurs in the playing schedules is higher as the playing time is longer, and the difference in the playing schedules between the allowable display devices is larger as the first time is longer, the first display device may determine the first absolute value once at intervals of longer time. The first time length is smaller, the allowable difference of the playing progress between the display devices is smaller, so that the first display device can determine the first absolute value once every shorter time. When the first duration is longer, the first display device can be prevented from frequently determining the first absolute value to further adjust the first playing progress, when the first duration is shorter, the playing progress difference of each display device (namely, the display device accessing the business of the auditorium) in the virtual auditorium can be ensured to be smaller, and the use effect of the chatting function of the display device while watching is ensured.
Optionally, the first display device may obtain a first duration preset by the staff, or the first duration may also be flexibly adjusted by the user. For example, the first duration may be 5 seconds, and the difference in the playing schedules within 5 seconds generally has little influence on the communication of the user with respect to the video, and at this time, the frequency of the first display device adjusting to determine the first absolute value and adjusting to the first playing schedule is not too great. Alternatively, the first duration may be other values, such as 3 seconds, 4 seconds, or 6 seconds.
The first display device may adjust the first playing progress of the target video in a plurality of ways, and the embodiment of the present application is explained by taking two alternative implementation manners as examples.
In an alternative implementation manner, the first display device may directly jump from the current playing progress of the target video to the theoretical playing progress. Illustratively, at 8:00 the first display device determines that the first playback progress of the target video is at 20 minutes, 5 seconds, and the theoretical playback progress of the target video is at 20 minutes, 15 seconds, then the first display device may skip between the 20 minutes, 5 seconds, and the 20 minutes, 15 seconds of the target video, and play the portion of the target video immediately after the 20 minutes, 15 seconds.
In another alternative implementation manner, the first display device plays the part of the target video after the current playing progress at the second playing speed, and plays the part of the target video after the current playing progress at the first playing speed when the first absolute value is less than or equal to the second time length. The second playing speed is greater than the first playing speed, and the second duration is less than or equal to the first duration. This alternative implementation corresponds to fast-forward or double-speed playback of the target video.
Illustratively, the first duration is 5 seconds, the second duration is 0, the first playing speed is a speed of displaying 24 frames of images per second, and the second playing speed is a speed of displaying 48 frames of images per second, which is equivalent to performing double-speed playing on the target video, and the first playing speed is recovered when the first playing speed is consistent with the theoretical playing speed. If the first display device plays the target video at the first play speed of 8:00:00, and the first play progress of the target video is determined to be 20 minutes and 5 seconds, and the theoretical play progress of the target video is determined to be 20 minutes and 20 seconds, the first display device can increase the play speed of the target video and play the target video at the second play speed. Assuming that the first display device determines the first absolute value at 8:00:15 next time after the first display device at 8:00:00 has acquired the portion of the target video after 5 seconds at 20 minutes, at this time, the first playing progress and the theoretical playing progress of the first display device are both 35 seconds at 20 minutes, and the first absolute value is 0. The first display device may now resume the first playback speed, presenting 24 frames of images per second.
It should be noted that, if the first display device determines that the first absolute value is greater than the second duration when determining the first absolute value next time, the first display device may continue to play the target video at the second play speed. And playing the target video at the first playing speed again until the first display device determines that the first absolute value is less than or equal to the second time length. In this embodiment of the application, the second duration is taken as 0, optionally, the second duration may also be equal to the first duration, for example, equal to 5 seconds, or the second duration may also be 3 seconds or 2 seconds or other numerical values, and this embodiment of the application is not limited.
Optionally, in step 709, the controller of the first display device may adjust the first playing progress of the target video when the first absolute value is greater than the first time length, and control the display screen to play the target video at the adjusted playing progress.
Step 710, the first display device sends an acquisition request of the status indication information to the server.
Optionally, each display device (e.g., the first display device) in the virtual auditorium may also send a request for obtaining the status indication information to the server during the process of playing the target video. The acquisition request may carry an identification of the display device and an identification of the auditorium service. Alternatively, the first display device may send the acquisition request to the server every other fixed time period.
Alternatively, the controller of the first display device may generate the acquisition request and send the acquisition request to the server through the communication interface in step 710.
Step 711, the server sends the status indication information to the first display device according to the obtaining request.
When receiving an acquisition request sent by a display device, the server may determine the state of the auditorium service according to the identifier of the auditorium service carried by the acquisition request. The state of the auditorium service may include a stopped state or an active state, the state of the auditorium service being an active state when the auditorium service is operating normally, and the state of the auditorium service being a stopped state when the auditorium service is stopped for some reason. Further, the server may send the status indication information to the display device indicated by the identifier of the display device carried in the acquisition request. The state indication information is used for indicating the state of the auditorium service as follows: a stop state or a run state, the status indication information may carry an identification of the auditorium service.
Optionally, in step 711, the server may send the status indication information to the communication interface of the first display device according to the obtaining request.
