Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a live broadcast control method. Generating a first slicing file for a broadcasting control end to obtain through a first transmission protocol according to a received live broadcasting signal; if a control instruction sent out based on the first slice file is received, adjusting the second slice file according to the control instruction; the second slice file specifically includes: generating a slice file for the non-broadcast control end to obtain through a second transmission protocol according to the live broadcast signal; wherein the real-time property of the first transmission protocol is higher than the real-time property of the second transmission protocol.
In this embodiment, because the real-time property of the first transmission protocol is higher than that of the second transmission protocol, the first slice file acquired by the broadcast control personnel can be earlier than the second slice file acquired by the non-broadcast control end, so that the broadcast control personnel can conveniently execute the broadcast control operation by using the time difference between the first slice file and the second slice file. And because the first slice file acquired by the broadcasting control end and the second slice file acquired by the non-broadcasting control end are generated according to the same live broadcast signal, a special broadcasting control environment is not required to be built, so that public network broadcasting control can be realized, and the broadcasting control flexibility is improved.
The implementation details of the live broadcast control method according to this embodiment are specifically described below, and the following description is only provided for the convenience of understanding, and is not necessary for implementing this embodiment.
A flowchart of a live broadcast control method in this embodiment is shown in fig. 1, and includes:
And 102, generating a first slicing file for a broadcasting control end to obtain through a first transmission protocol according to the received live broadcasting signal.
The first transmission Protocol is generally a Protocol with higher Real-Time performance in the field, and for example, the first transmission Protocol may be a Real Time Messaging Protocol (RTMP Protocol), a Real Time Streaming Protocol (RTSP Protocol), or the like, and is not limited specifically herein.
In one example, step 102 may include the following sub-steps, as shown in FIG. 2:
and a substep 1021, storing the slice file represented by the live broadcast signal in the first area according to the sequence of the received live broadcast signals.
And a sub-step 1022 of detecting whether the slice file is stored in the first region. If the first area is detected to have the slice file stored, go to sub-step 1023; otherwise, returning to step 1022, it continues to detect whether the slice file is stored in the first area.
And a substep 1023 of generating a first slice file by means of a first transmission protocol, based on the current slice file stored.
Specifically, if ts represents a slice file, the obtained slice files are respectively as follows according to the sequence of the received live broadcast signals: ts1, ts2, ts3, … …, tn, which are sequentially stored in the first area. When it is detected that ts1 exists in the first area, ts1 is converted into ts1 'through the first transport protocol for the broadcast control end to obtain, and when it is detected that ts2 exists in the first area, ts1 is converted into ts 2' through the first transport protocol for the broadcast control end to obtain, and so on. It will be appreciated that the first slice file is generated by the first transport protocol each time a slice file entry is detected for the first region, i.e. in dependence on the current slice file being entered. By the method, the real-time performance of the first slice file acquired by the broadcast control end can be improved, and the first slice file acquired by the broadcast control end and the slice file represented by the live broadcast signal have no time interval as far as possible.
In other examples, a sequence table seq-table xml may also be generated according to the sequence of the received live broadcast signal, the name of the slice file stored in the first area, and the duration of the slice file, and stored in the first area. Xml can be generated as follows:
in an example, when the first clip file is obtained, a live link address live-url for the broadcast control end to obtain may be generated according to the first clip file, and the broadcast control end may obtain the first clip file according to the live link address.
And 103, judging whether a control instruction sent out based on the first slice file is received. If the control instruction sent based on the first slice file is judged to be received, entering step 104; otherwise, returning to step 101, re-receiving the live broadcast signal, and executing the subsequent operation.
Specifically, when the broadcast control personnel find that illegal contents exist in the first slice file, a control instruction can be sent in a key pressing mode, a touch control mode and the like, and the control instruction is used for adjusting the corresponding illegal contents in the slice file acquired by the non-broadcast control end.
In this embodiment, if a control instruction sent based on the first slice file is not currently received, it may be stated that the content represented by the current first slice file does not have illegal and illegal contents, and therefore, it is not necessary to adjust the second slice file corresponding to the current first slice file and acquired by the non-broadcast control end, the processing flow of the current first slice file is ended, and the step 101 is returned, and the subsequent operation is executed according to the received live broadcast signal again.
And 104, adjusting the second slice file according to the control instruction.
The second slice file specifically includes: and generating a slice file for the non-broadcast control terminal to acquire through a second transmission protocol according to the live broadcast signal, wherein the real-time performance of the first transmission protocol is higher than that of the second transmission protocol.
The second transmission protocol may include, but is not limited to: HTTP-based Streaming media network transport protocol (HTTP Live Streaming, abbreviated as "HLS" protocol).
In one example, a slice file represented by the live signal may be stored in the second area according to the order of the received live signals; and detecting whether the second area has the slice file stored, and generating a second slice file through a second transmission protocol according to the stored current slice file when detecting that the second area has the slice file stored. For example, if the slice file is denoted by ts, the obtained slice files are respectively: ts1, ts2, ts3, … …, tn. When it is detected that ts1 exists in the second area, ts1 is converted into ts1 "through the second transport protocol for the non-broadcast control end to obtain, and when it is detected that ts2 exists in the second area, ts1 is converted into ts 2" through the second transport protocol for the non-broadcast control end to obtain, and so on.
In an example, when the second slice file is obtained through conversion, a live link address for the non-broadcast control end to obtain may be generated according to the second slice file, and the non-broadcast control end may obtain the second slice file according to the live link address.
In addition, after a first slicing file for the broadcast control end to obtain is generated through a first transmission protocol according to the received live broadcast signal, the identity information of a user who sends a request to the live broadcast signal can be judged; if the user is judged to be the user of the broadcast control end, sending a first slicing file to the broadcast control end; and/or after the second slice file is acquired, the identity information of the user who sends the request to the live broadcast signal can be judged; and if the user is judged to be the user of the non-broadcast control end, sending a second slice file to the non-broadcast control end. For example, a specific request address may be allocated to the broadcast control terminal, so that whether the identity information of the user requesting the live signal is the broadcast control terminal or the non-broadcast control terminal may be determined according to the request address. Of course, the present embodiment does not limit the manner of determining the identity information.
As can be easily found, in the live broadcast control method provided by this embodiment, because the real-time property of the first transmission protocol is higher than that of the second transmission protocol, the first slice file acquired by the broadcast control personnel can be earlier than the second slice file acquired by the non-broadcast control end, so that the broadcast control personnel can perform broadcast control operation by using the time difference between the first slice file and the second slice file. And because the first slice file acquired by the broadcasting control end and the second slice file acquired by the non-broadcasting control end are generated according to the same live broadcast signal, a special broadcasting control environment is not required to be built, so that public network broadcasting control can be realized, and the broadcasting control flexibility is improved.
A second embodiment of the present invention relates to a live broadcast control method. The second embodiment is a further improvement on the first embodiment, and the specific improvement is that: in this embodiment, the second slice file is specifically obtained as follows: storing the slice files represented by the live broadcast signals in a second area according to the sequence of the received live broadcast signals; counting the number of the subsequently stored slice files when the current slice file is detected to be stored in the second area; and when the number of the slicing files reaches a preset value, generating a second slicing file through a second transmission protocol according to the current slicing file.
In this embodiment, a flowchart of a method for acquiring a second slice file is shown in fig. 3, and includes:
For example, if the slice file is denoted by ts, the obtained slice files are respectively: ts1, ts2, ts3, … …, tn, which are sequentially stored in the second area.
It should be emphasized that the current slice file as referred to herein specifically is: in the process of generating a first slicing file for a broadcast control end to obtain through a first transmission protocol according to a received live broadcast signal, when a current slicing file is detected in a first area, namely the current slicing file is converted into the first slicing file through the first transmission protocol, the current slicing file is called.
For example, if the first slice file is obtained just according to the stored current slice file a, when it is detected that the slice file a is stored in the second area, the second slice file is not generated through the second transmission protocol immediately according to the slice file a, but the subsequently stored slice files are continuously obtained after the slice file a is stored, and the number of the subsequently stored slice files is counted.
And 204, detecting whether the number of the slice files reaches a preset value. If the number of the slice files reaches the preset value, entering step 205; otherwise, returning to step 204, and continuing to detect whether the number of the slice files reaches a preset value.
The preset value can be set according to actual requirements. For example, the number of the optical fibers may be 3 or 5, and is not particularly limited herein.
And step 205, generating a second slicing file through a second transmission protocol according to the current slicing file.
With reference to the example in step 203, if the preset value is 3 and the time length of each slice file is 10s, and the number of the subsequently stored slice files is 3, a second slice file is generated according to the slice file a through a second transmission protocol, so that the time length of the slice file a acquired by the non-broadcast control end is at least later than the time length of the slice file a acquired by the broadcast control end: preset values per slice time, i.e.: 3 × 10s ═ 30 s.
As can be easily found, in the live broadcast control method provided by this embodiment, according to the order of the received live broadcast signals, the slice file represented by the live broadcast signals is stored in the second area; counting the number of the subsequently stored slice files when the current slice file is detected to be stored in the second area; and when the number of the slicing files reaches a preset value, generating a second slicing file through a second transmission protocol according to the current slicing file.
A third embodiment of the present invention relates to a live broadcast control method. The third embodiment is a further improvement on the first embodiment, and the specific improvement is that: in this embodiment, adjusting the second slice file according to the control instruction includes: extracting identification information of a target slice file from the control instruction, wherein the target slice file is as follows: forbidding the slice files acquired by the non-broadcast control end; searching a slice file corresponding to the identification information in the second slice file; and adjusting the second slice file by executing preset operation on the searched slice file. By extracting the identification information of the slice file acquired by the non-broadcast control terminal from the control instruction and executing the preset operation on the slice file corresponding to the identification information, the second slice file acquired by the non-broadcast control terminal does not have related contents such as illegal information and the like which are prohibited to be played.
A flowchart of the live broadcast control method in this embodiment is shown in fig. 4, and includes:
Since steps 301 to 303 in this embodiment are substantially the same as steps 101 to 103 in the first embodiment, the description is omitted here to avoid repetition.
And step 304, extracting the identification information of the target slice file from the control command.
Wherein, the target slice file is: and forbidding the slice files acquired by the non-broadcast control end.
In one example, the identification information is time information of the target slice file in each second slice file. For example, the first clip files for the broadcast control end to obtain are respectively: ts1 ', ts 2', ts3 ', … … and tn' respectively, wherein the second slice files acquired by the non-broadcast end are: ts1 ", ts 2", ts3 ", … …, tn". Wherein ts1 'and ts 1' have the same content, ts2 'and ts 2' have the same content, and so on. When the broadcast control personnel at the broadcast control end acquires and plays ts3 ', ts 3' is found to include illegal contents, and then the non-broadcast control personnel may acquire and play ts1 ".
In this case, the play controller may select ts3 'to obtain the time information of ts 3' in the first clip file, for example, if ts3 'starts to be played at the 30 th s in the playing process, the identification information of ts 3' may be: for 30 s. Thus, it can be determined that the identification information of the target slice file (in this example, ts3 ") is 30 s.
Here, the following is still explained as an example in step 304: that is, the slice file to be played at the 30 th s among the second slice files is searched, so that ts3 ″ can be locked and searched.
And step 306, adjusting the second slice file by executing preset operation on the searched slice file.
In one example, the slice file may be replaced with a multimedia file having the same duration as the found slice file. The multimedia file may be: an advertisement file, or the last slice file adjacent to the slice file. Therefore, related contents such as illegal information and the like which are forbidden to be played do not exist in the second slice file acquired by the non-playing control terminal.
For example, if the found slice file is ts2 ", ts 2" may be determined as an invalid slice file, and the ts2 "may be replaced by the last slice file adjacent to the slice file, that is, ts 1".
For another example, if the found slice file is ts2 ", ts 2" may be determined as an invalid slice file, and the ts2 "may be replaced by an advertisement file having the same duration as that of the slice file.
By the method, the second slice file acquired by the non-playing control end does not have related contents such as illegal information and the like which are prohibited to be played, and seamless transition between ts1 and ts 2' can be realized.
In other examples, an alarm prompt message may be sent to the user at the non-broadcast control end according to the searched slice file, so that the user at the non-broadcast control end can know in advance: since the slice file to be played next includes illegal contents, the service is not provided for the moment, and the multimedia file is used for replacing the illegal contents.
The present embodiment may be a modification of the second embodiment.
It is easy to find that, in the live broadcast control method provided in this embodiment, by extracting the identification information of the slice file that is obtained by the non-broadcast control end from the control instruction and executing the preset operation on the slice file corresponding to the identification information, the second slice file that is obtained by the non-broadcast control end does not have related content that is forbidden to be broadcast, such as illegal information.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
A fourth embodiment of the present invention relates to a live broadcast control system, as shown in fig. 5, including: a first protocol conversion module 401, configured to generate, according to a received live broadcast signal, a first slice file for a broadcast control end to obtain through a first transmission protocol; an adjusting module 402, configured to, when receiving a control instruction issued based on a first slice file, adjust a second slice file according to the control instruction; the second slice file specifically includes: a second protocol conversion module 403, configured to generate, according to the live broadcast signal and through a second transmission protocol, a slice file for the non-broadcast control end to obtain; wherein the real-time property of the first transmission protocol is higher than the real-time property of the second transmission protocol.
In one example, generating a first clip file for a broadcast control end to acquire according to a received live broadcast signal through a first transport protocol includes: storing a slice file represented by the live broadcast signal in a first area according to the sequence of the received live broadcast signal; and when the first area is detected to have the slice file stored, generating a first slice file through a first transmission protocol according to the stored current slice file.
