In the current online video live broadcast, when a user wants to watch live broadcast online, an index request needs to be sent to a live broadcast server through terminal equipment, after the server receives the index request, the server needs to wait for a live broadcast end to send a new data slice, then index information is generated based on the new data slice, and then the index information is returned to the terminal equipment; and the terminal equipment acquires the live audio and video data based on the index information so as to watch the live broadcast. In the mode, the server needs to wait for a new data slice before sending the index information, so that the timeliness of index information sending is reduced, the live broadcast starting speed is further reduced, in addition, if a live broadcast end sends data which is blocked, the waiting time is longer, and the live broadcast can generate obvious blocking. Based on this, the information sending method, the information sending device and the server provided by the embodiment of the invention can be applied to equipment with online live broadcast service.
To facilitate understanding of the present embodiment, first, a detailed description is given of an information sending method disclosed in the embodiment of the present invention, where an execution subject of the present embodiment is a server, and as shown in fig. 1, the method includes the following steps:
step S102, receiving a live broadcast request from a terminal device;
the terminal device generally refers to a device for playing a live broadcast, for example, a mobile phone, a notebook computer, a tablet computer, and the like; the live broadcast generally refers to online live broadcast, that is, a live broadcast picture of a live broadcast terminal can be instantly displayed on a terminal device through a server, for example, live game broadcast, live release meeting broadcast, live news broadcast and the like. The live broadcast request generally carries parameters such as a live broadcast scene, a live broadcast type, live broadcast content, and a live broadcast requirement, for example, the live broadcast scene is a game live broadcast, the live broadcast type is a game live broadcast of a certain anchor, the live broadcast content is a game picture and an anchor picture of an online live broadcast, and the live broadcast requirement may be a parameter such as high definition. In actual implementation, after receiving a live broadcast request from a terminal device, a server can obtain live broadcast data corresponding to the live broadcast request and other live broadcast information according to parameters carried by the live broadcast request.
Step S104, judging whether first live broadcast data corresponding to the live broadcast request exists in the cache;
the cache generally refers to a cache device installed in a server, and is also called as a cache or a high-speed memory; the first live broadcast data generally refers to audio and video data live broadcast on line by a live broadcast end, and includes audio and video data live broadcast within preset time from live broadcast request time. Specifically, after the server receives the live broadcast request, the server starts to cache live broadcast data sent by the live broadcast end in the cache device of the server. It should be noted that if the server starts the corresponding live broadcast service, the live broadcast data will be continuously cached in the service memory of the server, and if the live broadcast service is closed, the service memory will not exist, that is, the live broadcast data cached in the caching device will not exist.
For example, if the first live data corresponding to the live request is 10: 00: 00 live broadcast data generated by a live broadcast end, if the time period of the live broadcast data in the cache is 10: 00: 00-10: 00: and 10, judging that the first live broadcast data corresponding to the live broadcast request exists in the cache.
And step S106, if the first live broadcast data corresponding to the live broadcast request exists in the cache, sending the live broadcast index information corresponding to the live broadcast request to the terminal equipment.
The live broadcast index information can be understood as the storage address of each section of live broadcast data; the first live data and the live index information corresponding to the live request can be stored in a memory of the server in a cache manner. For example, when a user watches live broadcast online, the server may cache live broadcast data and corresponding live broadcast index information in a recent period of time.
Specifically, if first live broadcast data corresponding to a live broadcast request exists in the cache, the server may first send live broadcast index information corresponding to the live broadcast request to the terminal device, and since the server needs to wait for a live broadcast end to send a new data slice after receiving the live broadcast request, then index information is generated based on the new data slice, and then the index information is returned to the terminal device, there is a time delay in the middle, the live broadcast index information sent by the server includes live broadcast index information corresponding to part or all of live broadcast data already existing in the current cache, so that the terminal device can quickly receive the index information corresponding to the live broadcast data, and then quickly enter a live broadcast picture; certainly, the method further includes that after the server receives the live broadcast request, the server receives live broadcast index information corresponding to the live broadcast data, so that the terminal device can continuously receive the index information and continuously display the live broadcast data corresponding to the live broadcast request.
The invention provides an information sending method, which comprises the steps of firstly judging whether first direct broadcast data corresponding to a direct broadcast request exists in a cache after receiving the direct broadcast request from a terminal device; and if the first live broadcast data corresponding to the live broadcast request exists in the cache, sending the live broadcast index information corresponding to the live broadcast request to the terminal equipment. In the method, after the server receives the live broadcast request, if the live broadcast data corresponding to the request exists in the cache, the index information is sent to the terminal equipment, and the index information is sent without waiting for the arrival of a new data slice, so that the timeliness of sending the index information is improved, and the live broadcast starting speed is further improved.
The embodiment also provides another information sending method, and the embodiment is realized on the basis of the embodiment. The embodiment mainly describes a specific implementation manner of the step of sending the live broadcast index information corresponding to the live broadcast request to the terminal device. The method specifically comprises the following steps:
step 201, receiving a live broadcast request from a terminal device;
step 202, judging whether first live broadcast data corresponding to the live broadcast request exists in a cache;
and 203, if the first live broadcast data corresponding to the live broadcast request exists in the cache, sending live broadcast index information corresponding to the first live broadcast data to the terminal equipment.
The first live data may include live data in the cache, and may further include live data received by the server after receiving the live request. For example, the first live broadcast data may be identified, specifically, the first live broadcast data is split sequentially according to a time sequence, each split data is identified, the identification information of the first live broadcast data is determined as corresponding live broadcast index information, and the live broadcast index information is sent to the terminal device. And the terminal equipment can acquire corresponding live broadcast data according to the received live broadcast index information.
In step 203, a possible implementation manner is as follows: splicing and combining the linked list identification of the first direct broadcast data to obtain direct broadcast index information in a character string form corresponding to the first direct broadcast data; and sending the live broadcast index information to the terminal equipment.
The first broadcast data is received and cached usually in a data slice mode, each data slice may contain 0.3 second or 0.5 second audio and video, and the server caches the data usually in a linked list mode, so that each slice of the first broadcast data can be independently arranged on a corresponding linked list, each linked list has a corresponding linked list identifier, and finally the linked list identifier of the first broadcast data is obtained. In order to enable the terminal device to recognize the received live broadcast index information, the linked list identifiers of the first live broadcast data can be spliced and combined to obtain the live broadcast index information in the character string form corresponding to the first live broadcast data, and the live broadcast index information is sent to the terminal device, so that the terminal device can obtain the storage address of the first live broadcast data according to the live broadcast index information.
For example, the server caches 20 seconds of live data, where the 20 seconds of live data are 100 data slices; setting each data slice on a corresponding linked list, wherein the linked list identification of the first broadcast data can be 1-1, 1-2, …, 1-100; the linked list identifier is spliced and combined to obtain live broadcast index information in a character string form corresponding to the first live broadcast data, such as live broadcast index information in a character string form of 1-1-2-3 … 100 and the like, and then the live broadcast index information is sent to the terminal device.
In the above manner, after receiving a live broadcast request from a terminal device, first determining whether first live broadcast data corresponding to the live broadcast request exists in a cache; if the first live broadcast data corresponding to the live broadcast request exists in the cache, firstly, the live broadcast index information corresponding to the first live broadcast data is sent to the terminal equipment. In the method, after the server receives the live broadcast request, the server judges the cache state of the server, the index information corresponding to the first live broadcast data can be quickly responded, and is firstly sent to the terminal equipment. In addition, splicing and combining the linked list identification of the first live broadcast data to obtain live broadcast index information in a character string form corresponding to the first live broadcast data; sending the live broadcast index information to the terminal equipment so that the terminal equipment can identify the live broadcast index information and further acquire live broadcast data; index information is sent without passively waiting for the arrival value of the new data slice, so that the timeliness of sending the index information is improved, and the start speed of live broadcasting is further improved.
The embodiment also provides another information sending method, and the embodiment is realized on the basis of the embodiment. This embodiment mainly describes another possible implementation manner of the step of sending the live broadcast index information corresponding to the live broadcast request to the terminal device, including:
step 301, acquiring second live broadcast data with specified data volume;
the specified data volume can be specifically set according to the requirements of the terminal device, for example, the specified data volume can be set according to a playing scene, if the live data of the playing request is live game, the definition of a live broadcast picture is required to be good, and second live broadcast data with a small data volume (for example, live broadcast data of 1-2 seconds) can be generally obtained at the moment so as to improve the definition of the live broadcast picture; for another example, if the live broadcast data of the play request is live lecture broadcast, the continuity of the live broadcast is required to be better, and at this time, second live broadcast data with a larger data amount (for example, live broadcast data of 4 to 5 seconds) is usually obtained, so as to improve that the user can watch relatively more lecture content. The second live data is usually live data of a period nearest to the current time, and the second live data needs to have continuity with the subsequently acquired live data. That is, the subsequently acquired live data is live data based on time after the second live data, for example, the second live data is live data of 5 seconds closest to the current time, and the subsequently acquired live data by the server is live data after 5 seconds.
In the related technology, after the terminal device starts playing and sends the live broadcast request, the index information is received at first, and then the corresponding live broadcast data is obtained according to the index information. Based on this problem, the above steps are a possible implementation:
if the live broadcast request indicates that second live broadcast data needs to be acquired, extracting a numerical value of a specified data volume from the live broadcast request; and acquiring second live broadcast data with specified data volume.
Usually, when the terminal device sends a live broadcast request, a parameter for acquiring second live broadcast data can be set; if the acquisition parameters are carried, the second live broadcast data are indicated to be acquired, and then a numerical value of a specified quantity can be extracted from the live broadcast request, wherein the numerical value can be the quantity of data slices of the second live broadcast data or the time of the second live broadcast data. Specifically, the second live data may be obtained from a current cache of the server according to a numerical value of the specified data volume, or the second live data may be obtained from live data newly received by the server according to the numerical value of the specified data volume. In addition, the second live broadcast data Of the specified data amount may be audio/video data Of a plurality Of or a specified number Of GOPs (Group Of pictures).
Another possible implementation: acquiring second live broadcast data with specified data volume from the cache; the second live data belongs to at least a part of the first live data.
Because the first live broadcast data corresponding to the live broadcast request exists in the cache, after the server receives the live broadcast request, in order to enable the terminal equipment to start broadcasting quickly and display a live broadcast picture, the second live broadcast data with specified data volume can be firstly obtained from the cache, and the specific specified data volume can be set according to the playing scene of the terminal equipment. The second live data may belong to at least a part of the first live data, or may be all of the first live data. The second live data typically belongs to a portion of the first live data.
Another possible implementation: acquiring second live broadcast data with specified data volume from the third live broadcast data; wherein the third live data includes: and after receiving the live broadcast request, receiving live broadcast data corresponding to the live broadcast request.
Of course, the second live data may not be acquired from the cache; second live data with a specified data volume can be directly obtained from third live data, wherein the third live data comprises: and after receiving the live broadcast request, receiving live broadcast data corresponding to the live broadcast request. Specifically, after the server receives the live broadcast request and waits for the live broadcast receiving end to return third live broadcast data, the server obtains live broadcast data corresponding to the live broadcast request from the received third live broadcast data. The method can acquire real-time live broadcast data so that a user can watch the latest live broadcast picture.
There is also a possible implementation: judging whether an account sending the live broadcast request has live broadcast watching permission or not; and if the account has the live broadcast watching permission, executing the step of acquiring second live broadcast data with the specified data volume.
After the server receives the live broadcast request, if first live broadcast data corresponding to the live broadcast request exists in the cache, whether an account sending the live broadcast request has live broadcast watching authority or not can be judged, specifically, whether the account sending the live broadcast request is a VIP (member) user or not can be judged in account information stored in the server, and when the account has the live broadcast watching authority, namely the user is a member user, a step of acquiring second live broadcast data with specified data volume is performed. Namely, the user can enjoy quick start-up when watching the live broadcast, and the time waiting for the broadcast is reduced.
And step 302, sending the second live broadcast data and the live broadcast index information corresponding to the live broadcast request to the terminal equipment.
After the server acquires the second live broadcast data, the server can directly send the second live broadcast data and the live broadcast index information corresponding to the live broadcast request to the terminal equipment, so that the terminal equipment can immediately play a live broadcast picture displayed by the second live broadcast data, then acquire the corresponding live broadcast data according to the received live broadcast index information, and after the second live broadcast data is played, the server can play the live broadcast data corresponding to the live broadcast index information. According to the method, when the live broadcast index information is sent, part of live broadcast data in the cache is sent to the terminal equipment together, the time for the terminal equipment to wait for starting broadcast can be reduced, and the time for starting a screen is reduced.
It should be noted that, after receiving the live broadcast data, the server needs to encode the received live broadcast data in advance, and then sends the corresponding encoded live broadcast data to the terminal device according to the live broadcast index information sent by the terminal device.
In addition, the method further comprises:
(1) if the first live broadcast data corresponding to the live broadcast request does not exist in the cache, receiving fourth live broadcast data corresponding to the live broadcast request; wherein the fourth live data includes: after receiving a live broadcast request, receiving live broadcast data corresponding to the live broadcast request;
(2) and sending the index information corresponding to the fourth live broadcast data to the terminal equipment.
When a server is in live broadcasting, the server usually has no cache when a first user (a first terminal device) sends a live broadcasting request; the server will typically cache when a second user (second terminal device) sends a live request; therefore, if the first live data corresponding to the live request does not exist in the cache, it is necessary to wait for receiving fourth live data sent by the live terminal, where the fourth live data includes: after receiving a live broadcast request, receiving live broadcast data corresponding to the live broadcast request; the fourth live data is usually a preset amount of live data, and for example, the live end sends the live data every 20 seconds or 10 seconds. And then, sending the index information corresponding to the fourth live data to the terminal equipment so that the terminal equipment can acquire the fourth live data according to the index information and further play a live picture.
In the above mode, firstly, after the server receives the live broadcast request, the server can quickly respond to and send the index information by judging the cache state of the server, and the index information is sent without passively waiting for a new data slice, so that the timeliness of sending the index information is improved; in addition, the second live broadcast data with the specified data volume can be sent to the terminal equipment while the index information is sent, so that the terminal equipment can start broadcasting quickly, the first screen time is reduced, the live broadcast starting speed is improved, and the live broadcast experience of a user is improved.
Referring to the flow diagrams of the information transmission method shown in fig. 2 and fig. 3, a live scenario of p2p and a Content Delivery Network (CDN) server are taken as an example of an execution subject. As shown in fig. 2, after a CDN server receives a p2p index request (corresponding to the live broadcast request) sent by a terminal device (which may also be a play end), it is first determined whether live broadcast data cached in a memory of the server exists, and if so, group index information processing is performed on the live broadcast data cached, specifically, a linked list identifier of live broadcast data of a specified data amount in the live broadcast data cached may be spliced and combined to obtain live broadcast index information in a corresponding character string form, and then the live broadcast index information is sent to the terminal device; if not, group index information processing is carried out on the live broadcast data received by the CDN server, specifically, splicing and combining processing can be carried out on the linked list identification of the live broadcast data received by the CDN server, the corresponding live broadcast index information in the form of character strings is obtained, and then the live broadcast index information is sent to the terminal equipment.
As shown in fig. 3, after receiving the index request, the CDN server sends, to the playing end, live broadcast data (corresponding to the audio/video data of multiple gops in fig. 3) cached in the memory of the server and index information (corresponding to the audio/video slice index in fig. 3) corresponding to the index request, so that the playing end can start playing a live broadcast frame of the audio/video data of multiple gops; then, the playing end sends the index information (corresponding to the slicing request in fig. 3) to the server based on the index information corresponding to the index request, and then sends subsequent audio and video data to the playing end. The index request is used for the playing end to obtain slice index information; the slicing request is used for the playing end to obtain specific audio and video data.
The above-mentioned information transmission method has the same technical features as the information transmission method provided in the above-mentioned embodiment, so the same technical problems can be solved, and the same technical effects can be achieved.
