Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
The embodiment of the invention provides a media transmission method, which enables users in a communication group to publish media data in the communication group on the Internet in a live broadcast mode. In one example, the media data is distributed in a live manner by a primary user in the communication group, that is, a user who establishes the communication group. In one example, the master user may be a master of the web channel, or a teacher giving lessons for web teaching, or the like. In one example, the media data may also be published by other users in the communication group in a live manner. In one example, the communication group may be colloquially referred to as a room or channel. In one example, the media may refer to different types of media content, such as video, audio, multimedia, and so on.
Specifically, after the master user establishes the communication group, other users need to join the communication group to obtain media data, such as a real-time video of the master user, issued by the master user in the communication group. In this case, the other users may also distribute media data in the communication group (for example, open their own real-time video, etc.), comment on the media data distributed by the users in the communication group, and so on. Meanwhile, the master user can also live the media data issued in the communication group, namely, the link address of the media data is obtained and the media data is shared in the network, and other users in the network can play the media data by accessing the link address through the browser. In one example, the link address is a Uniform Resource Locator (URL) address in the form "http://". It can be seen that the media transmission method provided in the embodiment of the present invention combines media transmission using a private protocol with media transmission using a public protocol.
The establishing of the communication group for resource distribution is media transmission using a private protocol, which may be referred to as an interactive mode. For example, the User Datagram Protocol (UDP) is a proprietary Protocol that can be used in the interactive mode. The user interaction supporting the communication group by the UDP protocol has the characteristic of low time delay, and multiple interactive parties can see the video image of the opposite party in real time and hear the clear sound of the opposite party. In particular, each user in the communication group may publish media data, which needs to be forwarded to other users in the communication group via the server supporting the interactive mode. Therefore, considering the load capacity of the server supporting the interactive mode, the interactive mode has a certain limit to the number of participants of the communication group, and the interactive mode needs to install a specific client to analyze the private protocol.
The resource sharing by generating the link address is media transmission by adopting a public protocol, and can be called a live broadcast mode. Since the media transmission in live broadcasting is not bidirectional, a larger scale of participants is allowed, such as live broadcasting of a large football match in which hundreds of thousands of people watch simultaneously, and the like. In one example, the Content Delivery Network (CDN) may be used for delivery, and the HyperText Transfer Protocol (HTTP) download may be used at the client.
In one example, the CDN is a one-layer intelligent virtual network constructed on the basis of the internet, and is configured by node servers, and is capable of directing a user request to a node server closest to a user according to network traffic, connection of each node server, a load condition, a distance to the user, response time, and other comprehensive factors, so that the user can obtain a desired content nearby, thereby increasing a response speed of the user accessing a website and avoiding a situation of internet congestion.
Table 1 shows the characteristics of the interactive mode and the live mode. It can be seen that the media transmission method provided by the embodiment of the invention combines the two modes, and has the characteristics of high participation of the interactive mode and wide audience of the live broadcast mode in the same set of media transmission system.
TABLE 1
Fig. 1 is a schematic diagram illustrating a media delivery server 100 according to an embodiment of the present invention, where the media delivery server 100 is used to implement integration of an interactive mode and a live mode. In one example, the media delivery server 100 includes: a communication unit 101, a first processing unit 102 and a second processing unit 103.
The communication unit 101 is configured to receive a media push request and/or a media forwarding request for a communication group. In one example, the media push request is a live media transmission without specifying a recipient. In one example, the media forwarding request is an interactive media transmission that can only be received by users in the communication group.
The first processing unit 102 is configured to send, when the communication unit 101 receives the media forwarding request, first media data corresponding to the media forwarding request to a member user in the communication group. In one example, the member users are users of the communication group other than the sender of the media forwarding request. The second processing unit 103 is configured to, when the communication unit 101 receives the media push request, send second media data corresponding to the media push request to the stream push server.
In one example, the media delivery server 100 only receives the media forwarding request at a certain time, i.e. only the interactive mode is triggered. In one example, the media transmission server 100 may receive a media forwarding request and a media pushing request sent for the same media data, and then the media data is transmitted in both an interactive manner and a live manner.
In one example, the second processing unit 103 is further configured to: and providing the link address of the second media data received from the streaming push server to the sender of the media push request. Note that, in the live broadcast mode, the second media data delivered by the CDN is accessed by other clients in the network through a link address, and the link address is generated by the streaming server.
Fig. 2 is a system interaction diagram of the media delivery server 200 and other devices in the network according to the embodiment of the present invention. In one example, the media delivery server 200 includes: a communication unit 201, a first processing unit 202 and a second processing unit 203.
In one example, the communication unit 201 is configured to receive a media transmission request, such as a media forwarding request and/or a media pushing request, sent by the user terminal 211 through the network 210. In one example, the communication unit 201 provides a media forwarding request to the first processing unit 202 for processing, the media forwarding request corresponds to media data interaction in the communication group, and the media pushing request is provided to the second processing unit 203 for processing.
In one example, the first processing unit 202 obtains first media data corresponding to the media forwarding request, determines the addresses of the member users in the communication group, and sends the first media data to the member users 213, 214, and 215 in the communication group, that is, to other users in the communication group except the user terminal 211. It should be noted that the user terminal 211 may be a primary user for creating a communication group, or may be a newly added user after the communication group is created.
In one example, the second processing unit 203 obtains second media data corresponding to the media push request, and sends the second media data to the streaming push server 212. After receiving the second media data, the stream push server 212 allocates a link address to the second media data and returns the link address to the second processing unit 203, and the second processing unit 203 sends the link address to the communication unit 201, and the communication unit 201 feeds back the link address to the user terminal 211 via the network 210.
Fig. 3 is a schematic structural diagram of a media transmission system 300 according to an embodiment of the invention. In one example, the media transmission system 300 includes: a media interface machine 301 and a streaming server 302.
The media interface machine 301 is configured to receive a media push request and/or a media forwarding request for a communication group. When the media interface machine 301 receives the media forwarding request, the first media data corresponding to the media forwarding request is sent to the member users in the communication group. When the media interface machine 302 receives the media pushing request, the second media data corresponding to the media pushing request is sent to the stream pushing server 302. The streaming server 302 is configured to distribute the second media data in a content distribution network.
In one example, the media transmission system 300 may be a server, which includes two modules for implementing the functions of the media interface machine 301 and the streaming server 302, that is, the media interface machine 301 and the streaming server 302 may be integrated into a server.
Fig. 4 is a schematic structural diagram of a media transmission system 400 according to an embodiment of the present invention. In one example, the media transmission system 400 includes: a media interface machine 401 and a streaming server 402.
In one example, the media interface machine 401 determines the type of the media transmission request after receiving the media transmission request sent by the first user terminal 404 through the network 403. If the media forwarding request is received, the media interface machine 401 parses a communication group and first media data corresponding to the media forwarding request, and forwards the first media data to the member user 405 in the communication group. In one example, 3 other users 405 in the communication group receive the first media data published by the first user terminal 404.
If the media pushing request is received, the media interface machine 401 sends the second media data corresponding to the media pushing request to the stream pushing server 402. Further, the media interface machine 401 is configured to: the link address of the second media data is received from the streaming server 402 and fed back to the sender of the media push request (i.e. the first user terminal 404).
In one example, the media transmission request carries a request type, and the media interface machine 401 learns whether a media forwarding request or a media pushing request is received by analyzing the request type.
Further, the streaming server 402 transmits the second media data to the content distribution network 406 for live broadcasting. In one example, the content distribution network 406 includes: a transcoding server 416 and one or more content distribution servers 426.
The transcoding server 416 is configured to convert the second media data into a browser format and send the browser format to the one or more content distribution servers 426. The content distribution server 426 is configured to provide the data in the browser format to the second user terminal 407 requesting the second media data. In one example, the second user terminal 407 acquires the second media data by clicking a link address. It can be seen that the media transmission system 400 shown in fig. 4 can fully utilize the function of CDN delivery, and improve the user scale.
Fig. 5 is a schematic structural diagram of a media transmission system 500 according to an embodiment of the invention. In one example, the media transmission system 500 includes: the working principle of the media interface machine 401, the streaming push server 402, the network 403, the first user terminal 404, and the other users 405 in the communication group is as described in fig. 4, and will not be described herein again.
Further, the media transmission system 500 further includes: a content distribution network 506 for live broadcasting of the second media data in the network. Specifically, the content distribution network 506 includes: access server 516, transcoding server 526, content distribution server 536. The operation principle of the transcoding server 526 and the content distribution server 536 can refer to fig. 4. It should be noted that the access server 516 is provided in a general content distribution network. That is, the media transmission system 500 shown in fig. 5 employs a conventional content distribution network.
Fig. 6 is a schematic structural diagram of a media delivery server 600 according to an embodiment of the present invention. In one example, the media delivery server 600 includes: a control module 601, a media interface module 602, and a stream pushing module 603.
The control module 601 is configured to receive a media pushing request and/or a media forwarding request for a communication group, trigger the media interface module 602 to perform media transmission in an interactive manner when determining that the media forwarding request is received, and trigger the stream pushing module 603 to perform media transmission in a live broadcast manner when determining that the media pushing request is received. In an example, the media interface module 602 may be implemented by an existing media interface machine, and the streaming module 603 may also be implemented by an existing streaming server.
Fig. 7 is a schematic structural diagram of a user terminal 700 in an embodiment of the present invention. In one example, the user terminal 700 includes: a media data providing unit 701, a communication group control module 702, and a media push control module 703. In one example, the user terminal 700 is the first user terminal 404 shown in fig. 4.
In one example, the media data providing unit 701 is used for providing media data, for example, the media data providing unit 701 may be a camera module integrated on a user terminal. The communication group control module 702 is configured to create a communication group according to the first trigger signal, send a media forwarding request for the communication group to the network 403, obtain first media data corresponding to the media forwarding request from the media data providing unit 701, and send the first media data to the network 403.
The media push control module 703 is configured to send a media push request corresponding to the second media data to the network 403 according to the second trigger signal. In one example, the user terminal 700 may simultaneously transmit the first media data in both the interactive mode and the live mode. It can be seen that different media transmission modes are adopted for users with different participation requirements, so that the scheme of the embodiment of the invention has high flexibility. Users with high participation requirements or high priority can obtain media data in an interactive mode. Specifically, the user is added by creating a communication group, and a media forwarding request is issued to distribute the media data to the user. The users with low participation requirement or low priority adopt a live broadcasting mode, the media data is sent through the media pushing request, and for the part of users, a specific client does not need to be installed for analyzing the media data, so that the flow and the cost of the users are saved.
Fig. 8 is a schematic structural diagram of a user terminal 800 in an embodiment of the present invention. In one example, the user terminal 800 includes: a media data providing unit 701, a communication group control module 702, and a media push control module 703. Further, the ue 800 further includes: a display module 804.
In an example, the display module 804 is configured to display a first button 814 and send the first trigger signal to the communication group control module 702 when the first button 814 is sensed to be clicked. In an example, the display module 804 is configured to display a second button 824, and send the second trigger signal to the media push control module 703 when the second button 824 is sensed to be clicked. In one example, the second button 824 is not present in the interface at the same time as the first button 814, but is located in its lower level interface. That is, the second button 824 will not appear in the interface until the first button 814 is clicked to initiate the media transmission in the interactive mode.
In one example, the media push control module 703 is further configured to: the link address of the second media data is received from the network 403 and provided to the display module 804 for display.
Fig. 9 is a flowchart illustrating a media transmission method 900 according to an embodiment of the invention. In one example, the media transmission method 900 includes the following operations.
In step 901, a media push request and/or a media forwarding request for a communication group is received. In step 902, when the media forwarding request is received, first media data corresponding to the media forwarding request is sent to the member users in the communication group. In step 903, when the media push request is received, the second media data corresponding to the media push request is sent to the stream push server. In one example, the media delivery method 900 may be implemented using the media delivery server 100 shown in fig. 1. In one example, the media delivery server may include a processor and a memory. The memory is used for storing the operation instructions of the step 901 and the step 903. It is noted that steps 902 and 903 are executed steps triggered by a condition, for example, the triggering condition for executing step 902 is that the media forwarding request is received, and the condition for executing step 903 is that the media pushing request is received. Therefore, the order of execution between steps 902 and 903 need not be emphasized.
Fig. 10 is a flowchart illustrating a media transmission method 1000 according to an embodiment of the invention. In one example, the media transmission method 1000 includes the following operations.
At step 1001, a master user creates a communication group. In one example, step 1001 is implemented by clicking on a create communication group option on the interface after a host user logs in through a client installed on the first user terminal 404.
In step 1002, it is determined whether to start a live mode in the communication group. If yes, go to step 1003, if no, go to step 1007.
In step 1003, the first user terminal 404 sends a media pushing request, applies for a network resource to the streaming server through the media interface machine, and provides the second media data corresponding to the media pushing request to the streaming server through the media interface machine. It is noted that the second media data may be part or all of the first media data published by the first user terminal 404 in the communication group. In one example, when the media push request reaches the media interface machine, the media interface machine will turn on the bypass function, copy an audio-video data stream from the first media data as the second media data, and send the second media data to the stream push server.
In step 1004, the streaming server generates a link address for the second media data, and provides the link address to the host user through the media interface machine.
In step 1005, the streaming server uploads the second media data to the content distribution network, and the content distribution network transcodes and segments the second media data, and then generates browser-format data for distribution. In one example, the browser-formatted data is ts file slices or flv file streams, etc.
In step 1006, a user in the network obtains the second media data by accessing the link address. That is, the user in the network may not join the communication group without any interaction requirement, and may view part or all of the media data published in the communication group through the browser.
In step 1007, the users in the communication group perform media transmission in an interactive manner.
Further, while performing steps 1002-1007, step 1008 may be performed synchronously, and the master user invites other users to join the communication group, or the other users actively join the communication group after discovering the communication group at their own client to become new joining users. In one example, after other users join a communication group, media data in the communication group is forwarded to the user in real time through the media interface machine.
Fig. 11 is a flowchart illustrating interaction between a media interface machine 401 and a streaming server 402 according to an embodiment of the present invention. In step 1101, the media interface machine 401 receives a media push request from the first user terminal 404 and sends the media push request to the streaming server 402. The media push request carries the user identifier and the push type. Wherein the user identifier is used to indicate a sender of the media push request. In one example, the push type is used to indicate a technology adopted by the bypass Live broadcast, and may be a dynamic bit rate adaptation (HTTP Live Streaming, HLS), a Real Time Messaging Protocol (RTMP), a Streaming media format (Flash Video, FLV), or the like. In one example, bypassing live streaming refers to the media interface machine 401 copying a copy of the media data in interactive mode to the streaming server 402 in a bypassing manner.
In step 1102, after the streaming server 402 successfully applies for the resource to the CDN, it returns a corresponding link address to the media interface machine 401. In step 1103, the media interface machine 401 sends the second media data corresponding to the media push request to the streaming push server 402. In step 1104, the media interface machine 401 sends an instruction of bypassing the live broadcast end to the streaming push server 402, and carries a corresponding user identifier. In step 1105, the streaming push server 402 replies to the media interface machine 401 with an end acknowledgement.
Fig. 12(a) - (e) are interface diagrams of the client on the first user terminal 404 in the embodiment of the present invention. In turn, fig. 12(a) is a main interface diagram of a published media interaction, fig. 12(b) is an interface diagram of creating a communication group and starting a media interaction, fig. 12(c) is an interface diagram of a communication group with other users joined, fig. 12(d) is an interface diagram of starting a bypass live broadcast, and fig. 12(e) is an interface diagram of receiving a bypass live broadcast address.
In one example, FIG. 12(a) includes a "publish media interaction" button 1201. Clicking the "publish media interaction" button 1201 can access the main interface diagram of the published media interaction. At this time, an interactive title 1202 appears, and in fig. 12(a), the main user sets the interactive title 1202 as "my interaction". In the lower middle of the main interface diagram, there is a "start media interaction" button 1203, which can be regarded as the first button 814 in fig. 8.
Clicking on the "start media interaction" button 1203 brings up the interface of fig. 12 (b). In fig. 12(b), there are options 1204 for parameters, recording, bypassing the live broadcast, etc. The parameter option is used to set parameters of media interaction, the recording option is used to record media data in the interaction mode, and the bypass live broadcast option is used to trigger the live broadcast mode in the interaction mode, which can be seen as a second button 824 in fig. 8. In one example, the media data 1205 may be a real-time video picture captured by the primary user using the first user terminal 404. The host user may also publish textual information in the communication group through the comment field 1206. Status bar 1207 shows the status of the media interaction and the elapsed time. For example, the current state is media interaction, and the elapsed time is 10 seconds. In one example, fig. 12(b) also includes a mute button 1208 and a camera flip button 1209.
When the master user invites the other users 1210 to join the communication group, or the other users 1210 actively join the communication group, the interface is as shown in fig. 12(c), and the elapsed time is 30 seconds. In one example, there are 3 other users joining the communication group (assumed to be the newly joining user A, B, C), so there is not only the media data 1205 of the primary user in the interface, but also the media data 1211 of the newly joining user 1210. In this case, the media interface machine 401 is responsible for sending the media data 1205 of the primary user to the user terminal 405 of the new joining user 1210, and sending the media data of the new joining user a to the primary user and the new joining user B, C, and so on.
For the case where the bypass live option is selected by the primary user, fig. 12(d) will appear on the display screen of the first user terminal 404. Specifically, a bypass live window 1212 appears, which displays basic information of the live mode (such as a live name and a live description), and if a confirmation button in the bypass live window 1212 is clicked, the first user terminal 404 is triggered to send a media push request to the media interface machine 401. The elapsed time is 1 minute and 30 seconds, and after the elapsed time, the media data 1210 of the primary user will be provided to the streaming server 402 by the media interface machine 401 in a bypass live mode.
In fig. 12(e), after the resource application in the live broadcast mode is successful, the stream push server 402 returns the bypass live broadcast address to the master user through the media interface 401. In one example, the bypass live address 1213 would be displayed on the interface for copying and further distribution by the host user.
Note that fig. 12(a) to (e) are illustrated by taking a master user who creates a communication group as an example. For other users in the communication group, the live video frames shot by the user terminal 405 used by the user can be live broadcast on the internet by selecting the bypass live broadcast option on the interface of the user.
Therefore, the media transmission scheme provided by the embodiment of the invention combines the interactive mode and the live broadcast mode, so that the media transmission has the characteristics of interaction and live broadcast. In one example, bypass live broadcasting is realized by using a media interface machine, and media data released in an interactive mode is copied for live broadcasting, so that a live broadcasting mode is embedded in the interactive mode, and the combination of the live broadcasting mode and the interactive mode is realized while the change and the influence on the existing media transmission system are reduced as much as possible.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
