Description

Technical Field

[0001] The present disclosure relates to the field of video technology, and in particular to a video delivery method, device and system. Background Art

[0002] As users' requirements for security and flexibility become higher and higher, the application of video delivery systems is becoming more and more extensive. Figure 1 As shown, the video delivery system includes a distribution server, a control server and multiple display terminals. The user can distribute the images collected by the distribution server in different content collection modes to the corresponding display terminals through the control server.

[0003] In the related art, the specific video delivery method of the video delivery system is: when the distribution server receives the video delivery instruction sent by the control server, it creates a virtual desktop, then opens the video file to be delivered through the player on the virtual desktop, and then uses the acquisition software to capture the video file being played on the virtual desktop, and sends the captured image frames to the display terminal for display.

[0004] However, in the above-mentioned video delivery technology, the distribution server consumes a large amount of CPU (Central Processing Unit) resources and memory resources when establishing a virtual desktop, running a player, and running acquisition software, thereby reducing the processing efficiency of the distribution server.

[0083] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0084] The present disclosure provides a video delivery method, which is applied to a distribution server, such as Figure 2 As shown, the method comprises the following steps:

[0085] Step 201: Receive a video delivery instruction.

[0086] The video delivery instruction carries identification information of the video to be delivered and identification information of the display terminal.

[0087] For example, a user logs in to a control server through a browser, and performs a delivery operation through a WEB (World Wide Web) web page of the control server. Specifically, the user selects a display terminal to be delivered and a video to be delivered on the WEB web page, so that the control server obtains identification information of the video to be delivered and identification information of the display terminal to be delivered, and carries the identification information of the video to be delivered and the identification information of the display terminal in a video delivery instruction, and sends the video delivery instruction to the distribution server, that is, the distribution server receives the video delivery instruction.

[0088] It should be noted that the identification information of the video to be put can be a number or a URL, etc. As long as it is information that uniquely identifies a video, it can be used as the identification information of the video to be put. It can be understood that when the identification information of the video to be put is a number, the distribution server and the control server both pre-store the corresponding relationship between the number and the video. For example, the number of video A is 1, and the number of video B is 2. The distribution server and the control server both pre-store the corresponding relationship between video A and number 1, and video B and number 2.

[0089] It should be noted that the identification information of the display terminal may be information that can uniquely identify the display terminal, such as the hardware code of the display terminal. It is understandable that the distribution server and the control server also pre-store the corresponding relationship between the identification information of the display terminal and the display terminal.

[0090] Step 202: Acquire the video to be delivered according to the identification information of the video to be delivered, and determine the target display terminal according to the identification information of the display terminal.

[0091] For example, when the distribution server obtains the video delivery instruction, it parses the video delivery instruction to obtain the identification information of the video to be delivered and the identification information of the display terminal, and searches for the video to be delivered corresponding to the identification information of the video to be delivered in the correspondence table between the identification information of the video and the video, so as to obtain the video to be delivered; for example, if the identification information of the video to be delivered is number 1, then the obtained video to be delivered is video A; and searches for the target display terminal corresponding to the identification information of the display terminal in the correspondence table between the identification information of the display terminal and the display terminal, so as to obtain the target display terminal.

[0092] Step 203: Generate a relative time base of the video to be delivered according to the video to be delivered.

[0093] The relative time base includes a time axis of the relative play time of each image frame in the video to be delivered.

[0094] Optionally, the relative play time of each image frame in the video to be delivered is obtained; and the relative time base is generated according to the relative play time of each image frame.

[0095] For example, when the distribution server obtains the video to be delivered, it obtains the relative play time of each image frame in the video to be delivered, and then sorts the relative play time of each image frame in chronological order to obtain a time axis, and the time axis corresponds to the corresponding image frame to generate a relative time base. For example, the video to be delivered includes 3 image frames, namely image frame A, image frame B and image frame C, then the relative time base includes 0 minutes and 0 seconds - image frame A, 0 minutes and 1 seconds - image frame B, and 0 minutes and 2 seconds - image frame C.

[0096] It should be noted that, in actual applications, each frame of the video to be broadcast carries a relative playback time. The relative playback time is a value that is offset by a certain time unit relative to the starting frame, where the time unit refers to a relatively small time, for example, 1 / 100000 seconds. The smaller the time unit, the higher the accuracy.

[0097] Step 204: Send the corresponding image frame to the target display terminal according to the relative time base, so that the target display terminal displays the image frame.

[0098] Optionally, parse each image frame in the video to be delivered; determine whether the current time reaches the relative playback time corresponding to the current image frame; when it is determined that the current time reaches the relative playback time corresponding to the current image frame, send the current image frame to the target display terminal so that the target display terminal displays the current image frame.

[0099] For example, when the distribution server generates a relative time base for the video to be delivered, it parses each image frame in the video to be delivered in turn, and the image frame being parsed is the current image frame. For example, if the current image frame is the first frame, when parsing the first frame, the timer is started, the timer is controlled to start timing, and the current time of the timer is compared with the relative playback time of the first frame to determine whether the current time of the timer reaches the relative playback time of the first frame. When it is determined that the current time of the timer reaches the relative playback time of the first frame, the first frame is sent to the target display terminal so that the target display terminal displays the first frame; and so on, until each image frame in the video to be delivered is displayed on the target display terminal; when it is determined that the current time of the timer has not reached the relative playback time of the first frame, the current time of the timer is waited for to reach the relative playback time of the first frame. For example, the video to be broadcast includes 10 frames of images, and the relative time base includes: 01 seconds - the 1st frame of image, 02 seconds - the 2nd frame of image, 03 seconds - the 3rd frame of image, ..., 10 seconds - the 10th frame of image; when parsing the 1st frame of image, the timer is started, and if the timer is 1 second, it is determined that the current time has reached the relative playback time of the 1st frame of image specified in the relative time base, and the 1st frame of image is sent to the target display terminal; if the timer is 1.5 seconds, the relative playback time of the 2nd frame of image specified in the relative time base has not been reached, and the process waits until the timer is 2 seconds, and the 2nd frame of image is sent to the target display terminal; if the timer is 3 seconds, the relative playback time of the 3rd frame of image specified in the relative time base is reached, and the 3rd frame of image is sent to the target display terminal, until the 10 frames of image are sent.

[0100] Furthermore, the current image frame and the audio corresponding to the current image frame are sent to the target display terminal, so that the target display terminal displays the current image frame and the audio corresponding to the current image frame.

[0101] For example, while sending the current image frame to the target display terminal, the audio corresponding to the current image frame is also sent, so that when the target display terminal receives the current image frame and the audio corresponding to the current image frame, it simultaneously displays the current image frame and the audio corresponding to the current image frame to achieve synchronization of the image frame and the audio.

[0102] It should be noted that the above steps 201 to 204 can all be completed by the agent program in the distribution server starting the video file parser. Specifically, when the agent program of the distribution server receives the video delivery instruction, it starts the video file parser to execute steps 201 to 204.

[0103] The embodiment of the present disclosure provides a video delivery method. When receiving a video delivery instruction, the distribution server determines the video to be delivered according to the identification information of the video to be delivered carried in the video delivery instruction, determines the target display terminal according to the identification information of the display terminal carried in the video delivery instruction, and generates a relative time base of the video to be delivered according to the video to be delivered, and finally sends the corresponding image frame to the target display terminal according to the relative time base, so that the target display terminal displays each received image frame. It can be seen that the distribution server of the present disclosure only needs to establish a relative time base, and send each image frame of the video to be delivered to the target display terminal in time sequence for display according to the relative time base, without the need to establish a virtual desktop, run a player, or run acquisition software, thereby reducing the consumption of CPU resources and memory resources of the distribution server and improving the processing efficiency of the distribution server.

[0104] Further, such as Figure 3 As shown, after executing step 204, the following steps 205 to 207 are also included:

[0105] Step 205: Send the corresponding image frame to the control server according to the relative time base, so that the control server displays the image frame, and send the acquired playback adjustment instruction to the distribution server.

[0106] Wherein, the playback adjustment instruction carries target operation information.

[0107] For example, the distribution server can also send corresponding image frames to the control server based on the relative time base, that is, when it is determined that the current time has reached the relative playback time corresponding to the current image frame, the current image frame can be sent to the control server, so that the control server plays the current image frame when receiving the current image frame, and finally realizes the playback of the video to be delivered; when the user needs to adjust the video progress of the target display terminal, the video played on the control server can be full screen. In full screen mode, a scroll bar or fast forward bar, play button, pause button, etc. for video playback can be displayed, and the user can operate the fast forward bar and the corresponding buttons to adjust the playback status of the video played on the target display terminal.

[0108] It should be noted that when the current image frame is sent to the control server, the audio corresponding to the current image frame can also be sent at the same time, so that the control server plays the received current image frame and the audio corresponding to the current image frame simultaneously; it can be understood that the progress of the video to be delivered played on the control server is the same as the progress of the video to be delivered played on the target display terminal; and when there are multiple target display terminals, each corresponding video to be delivered can be played in the form of multiple small windows on the control server.

[0109] Step 206: Receive the playback adjustment instruction.

[0110] For example, a user can view the video to be played through the control server, and operate the progress bar and corresponding buttons of the video to be played, so that the control server obtains the playback adjustment instruction and sends the playback adjustment instruction to the distribution server, and the distribution server receives the playback adjustment instruction.

[0111] Step 207: Execute the target operation according to the target operation information.

[0112] Wherein, when the target operation information includes the relative play time of the image frame to be delivered, executing the target operation according to the target operation information can be achieved in the following manner:

[0113] A target image frame corresponding to the relative play time of the image frame to be delivered is obtained in the relative time base; and the target image frame is sent to the target display terminal so that the target display terminal displays the target image frame.

[0114] For example, when the distribution server receives the playback adjustment instruction, it parses the playback adjustment instruction. When the target operation information obtained by the analysis is the relative playback time of the image frame to be delivered, the target image frame corresponding to the relative playback time of the image frame to be delivered is searched in the relative time base, and the target image frame and the audio corresponding to the target image frame are sent to the target display terminal, so that the target display terminal displays the target image frame and the audio corresponding to the target image frame, thereby adjusting the playback progress of the video to be delivered. For example, if the relative playback time corresponding to the current image frame is 30 seconds, and the relative playback time of the image frame to be delivered in the user's target operation information is 40 seconds, then the image frame corresponding to 40 seconds can be found in the relative time base, that is, the target image frame, to achieve the fast-forward operation of the video to be delivered.

[0115] It should be noted that the target operation information may also be a pause operation, a play operation, etc., which is not limited in the present disclosure.

[0116] The embodiment of the present disclosure provides a video delivery method. When receiving a video delivery instruction, the distribution server determines the video to be delivered according to the identification information of the video to be delivered carried in the video delivery instruction, determines the target display terminal according to the identification information of the display terminal carried in the video delivery instruction, and generates a relative time base of the video to be delivered according to the video to be delivered, and finally sends the corresponding image frame to the target display terminal according to the relative time base, so that the target display terminal displays each received image frame. It can be seen that the distribution server of the present disclosure only needs to establish a relative time base, and send each image frame of the video to be delivered to the target display terminal in time sequence for display according to the relative time base, without the need to establish a virtual desktop, run a player, or run acquisition software, thereby reducing the consumption of CPU resources and memory resources of the distribution server and improving the processing efficiency of the distribution server; in addition, the user can also adjust the video to be delivered displayed in the display terminal by controlling the server, thereby improving the flexibility of adjusting the delivery video.

[0117] The present disclosure provides a video delivery method, which is applied to a control server, such as Figure 4 As shown, the method comprises the following steps:

[0118] Step 401: Get video delivery instructions.

[0119] The video delivery instruction carries identification information of the video to be delivered and identification information of the display terminal.

[0120] For example, a user logs in to a control server through a browser and performs a delivery operation through a WEB page of the control server. Specifically, the user selects a display terminal and a video to be delivered on the WEB page, so that the control server obtains identification information of the video to be delivered and identification information of the display terminal to be delivered.

[0121] Step 402: Send the video delivery instruction to the distribution server, so that the distribution server obtains the video to be delivered according to the identification information of the video to be delivered, determines the target display terminal according to the identification information of the display terminal, and generates a relative time base of the video to be delivered according to the video to be delivered, and sends the corresponding image frame to the target display terminal according to the relative time base, so that the target display terminal displays the image frame.

[0122] For example, when the control server obtains the identification information of the video to be delivered and the identification information of the display terminal, it carries the identification information of the video to be delivered and the identification information of the display terminal in the video delivery instruction, and sends the video delivery instruction to the distribution server, so that the distribution server obtains the video to be delivered according to the identification information of the video to be delivered, determines the target display terminal according to the identification information of the display terminal, and generates a relative time base of the video to be delivered according to the video to be delivered, and sends the corresponding image frame to the target display terminal according to the relative time base, so that the target display terminal displays the image frame.

[0123] The disclosed embodiment provides a video delivery method. When the control server obtains the video delivery instruction, it sends the video delivery instruction to the distribution server, so that the distribution server determines the video to be delivered according to the identification information of the video to be delivered carried in the video delivery instruction, determines the target display terminal according to the identification information of the display terminal carried in the video delivery instruction, and generates a relative time base of the video to be delivered according to the video to be delivered, and finally sends the corresponding image frame to the target display terminal according to the relative time base, so that the target display terminal displays each received image frame. It can be seen that the distribution server of the present disclosure only needs to establish a relative time base, and send each image frame of the video to be delivered to the target display terminal in time sequence for display according to the relative time base, without the need to establish a virtual desktop, run a player, or run acquisition software, thereby reducing the consumption of CPU resources and memory resources of the distribution server and improving the processing efficiency of the distribution server.

[0124] Further, such as Figure 5 As shown, after executing step 402, the following steps 403 and 404 are also included:

[0125] Step 403: Obtain a playback adjustment instruction.

[0126] Wherein, the playback adjustment instruction carries target operation information.

[0127] Optionally, the target operation information includes a relative play time of the image frame to be delivered.

[0128] For example, when the user needs to adjust the video progress of the target display terminal, the video played on the control server can be made full screen. In full screen mode, a scroll bar or fast forward bar, play button, pause button, etc. for video playback can be displayed. The user can operate the fast forward bar and the corresponding buttons so that the control server obtains the playback adjustment instructions.

[0129] Step 404: Send the play adjustment instruction to the distribution server, so that the distribution server performs the target operation according to the target operation information.

[0130] For example, when the control server obtains the playback adjustment instruction, it sends the playback adjustment instruction to the distribution server, so that the distribution server parses the received playback adjustment instruction and performs a corresponding operation according to the target operation information obtained by the analysis. When the target operation information is the relative playback time of the image frame to be delivered, the distribution server searches for the target image frame corresponding to the relative playback time of the image frame to be delivered in the relative time base, and sends the target image frame and the audio corresponding to the target image frame to the target display terminal, so that the target display terminal displays the target image frame and the audio corresponding to the target image frame, thereby realizing the adjustment of the playback progress of the video to be delivered.

[0131] The present disclosure provides a video delivery method, which is applied to a distribution server, a control server and a display terminal. Figure 6 As shown, the method comprises the following steps:

[0132] Step 601: The control server obtains a video delivery instruction.

[0133] The video delivery instruction carries identification information of the video to be delivered and identification information of the display terminal.

[0134] Step 602: The control server sends the video delivery instruction to the distribution server.

[0135] Step 603: The distribution server obtains the video to be delivered according to the identification information of the video to be delivered, and determines the target display terminal according to the identification information of the display terminal.

[0136] Step 604: The distribution server generates a relative time base of the video to be delivered according to the video to be delivered.

[0137] The relative time base includes a time axis of the relative play time of each image frame in the video to be delivered.

[0138] Step 605: The distribution server sends the corresponding image frame to the target display terminal according to the relative time base.

[0139] Step 606: The target display terminal displays the image frame.

[0140] Step 607: The distribution server sends the corresponding image frame to the control server according to the relative time base.

[0141] Step 608: Control the server to display the image frame, and send the acquired playback adjustment instruction to the distribution server.

[0142] The play adjustment instruction carries target operation information, and the target operation information includes the relative play time of the image frame to be played.

[0143] Step 609: The distribution server obtains a target image frame corresponding to the relative play time of the image frame to be delivered in the relative time base.

[0144] Step 610: The distribution server sends the target image frame to the target display terminal.

[0145] Step 611: The target display terminal displays the target image frame.

[0146] The disclosed embodiment provides a video delivery method. When the control server obtains the video delivery instruction, the control server sends the video delivery instruction to the distribution server, so that the distribution server determines the video to be delivered according to the identification information of the video to be delivered carried in the video delivery instruction, determines the target display terminal according to the identification information of the display terminal carried in the video delivery instruction, and generates a relative time base of the video to be delivered according to the video to be delivered, and finally sends the corresponding image frame to the target display terminal according to the relative time base, so that the target display terminal displays each received image frame.
