Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in other sequences than those illustrated or otherwise described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense to distinguish one object from another, and not necessarily to limit the number of objects, e.g., the first object may be one or more. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The live broadcasting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a flowchart illustrating a live broadcasting method provided in an embodiment of the present application, where the live broadcasting method is applied to a first electronic device for accessing a target live broadcast, that is, an electronic device for watching the target live broadcast.
As shown in fig. 1, the live broadcasting method may include:
step 101: and receiving first text information sent by second electronic equipment under the condition of accessing the target live broadcast.
The target live broadcast can be a video live broadcast or a pure audio live broadcast.
The second electronic device described herein is an electronic device for distributing a target live broadcast, that is, an electronic device for a host user to perform a target live broadcast.
The first text information is text information corresponding to target live broadcast content, and is used for representing live broadcast content (mainly voice content) in the target live broadcast in a text form.
In the embodiment of the application, under the condition that the first electronic device is accessed to the target live broadcast, the first text information sent by the second electronic device can be received.
Step 102: the first text information is displayed.
In the embodiment of the application, after receiving the first text information sent by the second electronic device, the first electronic device can display the first text information in the target live broadcast, that is, display the live broadcast content in a subtitle form.
Because the data volume of the text information is small, a Transmission Control Protocol (TCP) can be adopted for Transmission, and the TCP adopts a retransmission mechanism of three-way handshake, so that compared with a User Datagram Protocol (UDP) adopted for transmitting audio and video data, the reliability of text data Transmission can be ensured, even if the live video data and/or audio data are seriously lost due to poor network environment and blocked and cannot be seen and/or listened to, the live content can still be known by reading the text information in the screen, and the quality and effect of live broadcast are improved. Especially for important live broadcast such as network teaching, network conference and the like, the probability that the user misses important live broadcast content can be reduced, and the live broadcast watching efficiency is improved.
Alternatively, the first text information may be converted from the voice information in the target live broadcast. A microphone device (such as a microphone on a mobile phone or a professional microphone device) is provided at the position of a general anchor user to collect voice information of the anchor user. In the embodiment of the application, the second electronic device can convert the voice information acquired by the microphone into the text information in real time through the voice recognition technology, and then send the text information obtained through conversion to the first electronic device for accessing the live broadcast for display, so that the live broadcast audience can view the text information.
It can be understood that, when displaying the first text information converted from the voice information, the first electronic device may only display the first text information converted from the current voice information in the target live broadcast, or may display the first text information converted from the current voice information in the target live broadcast while displaying the first text information converted from the current voice information in the target live broadcast, so that the user may review the live broadcast content.
Optionally, the first text information may also be generated by editing the content to be live of the target live broadcast before the target live broadcast starts. For example, for live online lecture, a lecturer may arrange lecture content into a text file of an electronic file in advance, and store the text file in the second electronic device, so that the second electronic device may send the text file to the first sub-electronic device under the condition that the first electronic device is accessed to a target live broadcast, so that the first electronic device may display the text file for viewing by a live broadcast audience.
It is understood that the first text information may be a live content outline (e.g., a general description of live content), or may be detailed live content (e.g., what the anchor user says is substantially or entirely the content in the first text information during live broadcast), and of course, specific situations may be selected according to actual requirements such as importance of live content.
Optionally, in this embodiment of the application, when the first text information is obtained by converting from the voice information in the target live broadcast, and when the first text information obtained by converting from the current voice information in the target live broadcast is displayed, and the first text information obtained by converting from the historical voice information in the target live broadcast is also displayed, or when the first text information is generated by editing the content to be live broadcast in the target live broadcast before the target live broadcast starts, the first text information may be displayed in a scroll display manner.
In addition, in order to facilitate the user to review the previous live content and view the content to be live, a target control for controlling scrolling and page turning may be further provided, for example, as shown in fig. 2, a display area 201 displays the first text information 202 in a scrolling display manner, a slider 203 for controlling scrolling and page turning is displayed on the right side of the display area 201, the slider 203 is dragged upwards to turn the page, and the slider 203 is dragged downwards to turn the page. Of course, the first text information may also be displayed in other display manners, and the specific situation may be set according to actual requirements.
Optionally, in a process of displaying the first text information when the first text information is generated by editing the content to be live broadcast of the target live broadcast before the target live broadcast starts, the live broadcast method may further include: in the first text information, target text information matching current voice information in the target live broadcast is identified.
In the embodiment of the present application, in order to facilitate watching of live broadcast, a user may obtain current live broadcast content in time according to first text information, or locate corresponding text content in the first text information in time according to the live broadcast content, and may mark target text information in the first text information that matches current speech information in target live broadcast, where the target text information may be highlighted specifically in a highlight manner, or as shown in fig. 2, the target text information may be highlighted in bold and underline manners: "bbbbbb" and the like.
When the first text information is displayed in a rolling display mode, if the target text information matched with the current voice information in the target live broadcast is not displayed, the target text information can be automatically rolled and displayed. In addition, the first text information can display a sentence in each line, so that the displayed content is not too much to influence the reading and viewing of the user.
Optionally, the aforementioned "identifying, in the first text information, target text information that matches current speech information in the target live broadcast" may include:
receiving a target index value sent by second electronic equipment; and searching the target text information in the first text information according to the target index value, and identifying the searched target text information.
The target index value is determined according to current voice information in the target live broadcast and corresponds to the target text information.
In the embodiment of the application, the second electronic device can match the current voice information in the target live broadcast with the text content in the first text information in the live broadcast process.
If the corresponding text content (i.e. the target text information) is matched, the index value of the text content in the first text information (corresponding to the target index value, i.e. the specific position in the first text information, such as the information of the line number, the column number, etc.) may be sent to the first electronic device. And the first electronic equipment searches the text content in the first text information according to the received index value, and marks the searched text content for the user to check.
If the corresponding text content is not matched, the text information obtained by converting the current voice information (hereinafter referred to as second text information, which is text information not included in the first text information) may be sent to the first electronic device. And the first electronic equipment receives the second text information sent by the second electronic equipment, and adds the received second text information to the target position in the first text information to become a part of the first text information for the user to view. And the target position is behind the text information corresponding to the voice information before the current voice information. For example, the first text information is: "the moon light before bed, in particular, the ground frost. To look at the moon at first ", and the text information corresponding to the current voice information is: if the text message is not included in the first text message, the text message of "lower head and home town" is added to "bright moon before bed, doubtful that frost is on the ground. After the first hope of bright moon is lifted, new first text information is formed: "the moon light before bed, in particular, the ground frost. To look at the moon and look low, think about hometown. The text information in the original first text information may include, in addition to the text information generated by editing the content to be live broadcast according to the target live broadcast before the target live broadcast starts, text information obtained by conversion according to the voice information in the target live broadcast, for example, "take a look at the head of the moon" is the text information obtained by conversion of the voice information in the target live broadcast.
Meanwhile, the second electronic device may also add the second text information to the target position in the locally stored first text information for storage. The target position is the same as the previously described target position.
Optionally, when matching the current voice information in the target live broadcast with the text content in the first text information, the voice information may be converted into text information, and then the text information may be matched with the text content in the first text information. When the matching rate is greater than or equal to the preset value, the two are considered to be matched; and under the condition that the matching rate is smaller than the preset value, the two are considered not to be matched. The preset value may be a value greater than 0.5 and less than or equal to 1, such as 0.7, 0.8, or the like, or may be converted into a percentage, such as 70%, 80%, or the like. In addition, when matching the current voice information in the target live broadcast with the text content in the first text information, matching can be performed in units of one sentence, that is, matching is performed on a sentence-by-sentence basis.
Optionally, in a case where the target live broadcast is a live video broadcast, the first text information may be displayed in a display area of the screen that does not affect the user to view the live broadcast, for example, the live broadcast and the first text information may be respectively displayed in different display areas. In addition, the user can select to display the first text information or hide the first text information according to actual requirements.
Optionally, in this embodiment of the application, data transmission (for example, transmission of data such as a video stream, an audio stream, first text information, second text information, a target index value, and the like) between the first electronic device and the second electronic device may be implemented by a target server (for example, a video live broadcast server, an audio live broadcast server, and the like).
For example, as shown in fig. 3, a second electronic device that is a live source may send text data (e.g., first text information, second text information, etc.) and a video stream and an audio stream on-the-fly to a target server. And the target server sends the received text data and the video stream and the audio stream during live broadcasting to each piece of first electronic equipment serving as a live broadcasting access party. Wherein the text data is transmitted over TCP and the video stream and the audio stream are transmitted over UDP.
When the first text information is generated by editing the content to be live broadcast of the target live broadcast before the target live broadcast starts, the anchor user who performs the target live broadcast can upload the first text information to the target server through the second electronic device in advance before the target live broadcast starts. When the first electronic equipment is accessed to the target live broadcast, the target server issues first text information uploaded in advance by the anchor user to each first electronic equipment so as to be checked by a user watching the target live broadcast.
To sum up, in the embodiment of the present application, on the basis of live broadcasting original video data and/or audio data, a path of pure text subtitle data is added, and because the transmission mode adopted by the text data is more reliable, even if the live video data and/or audio data packet loss is seriously blocked and the live content cannot be seen and/or listened to in a network with poor signal quality, the live content can still be known by reading the subtitle information (i.e., text information) in the screen, thereby improving the quality and effect of live broadcasting.
Fig. 4 is a flowchart of a live broadcasting method provided in an embodiment of the present application, where the live broadcasting method is applied to a second electronic device for accessing a target live broadcast, that is, an electronic device used by an anchor user for performing the target live broadcast. The target live broadcast can be a video live broadcast or a pure audio live broadcast.
As shown in fig. 4, the live broadcasting method may include:
step 401: first text information is acquired.
The first text information is text information corresponding to target live broadcast content, and is used for representing live broadcast content (mainly voice content) in the target live broadcast in a text form.
Step 402: and sending the first text information to the first electronic equipment.
The first electronic device described herein is an electronic device for accessing a target live broadcast, that is, an electronic device for watching a target live broadcast.
In the embodiment of the application, after the second electronic device acquires the first text information, the first text information can be sent to the first electronic device, so that the first electronic device can display the first text information in the target live broadcast process, that is, live broadcast content is displayed in a subtitle mode for a user to view.
Because the data volume of the text information is small, a transmission control protocol (namely TCP) can be adopted for transmission, and the TCP adopts a retransmission mechanism of three-way handshake, so that the reliability of text data transmission can be ensured compared with a user datagram protocol (namely UDP) adopted for transmitting audio and video data, even if the live video data and/or audio data are seriously lost and blocked due to poor network environment and the live content cannot be seen and/or listened, the live content can still be known by reading the text information in a screen, and the quality and effect of live broadcast are improved. Especially for important live broadcast such as network teaching, network conference and the like, the probability that the user misses important live broadcast content can be reduced, and the live broadcast watching efficiency is improved.
Alternatively, the first text information may be converted from the voice information in the target live broadcast. A microphone device (such as a microphone on a mobile phone or a professional microphone device) is provided at the position of a general anchor user to collect voice information of the anchor user. In the embodiment of the application, the second electronic device can convert the voice information acquired by the microphone into the text information in real time through the voice recognition technology, and then send the text information obtained through conversion to the first electronic device for accessing the live broadcast for display, so that the live broadcast audience can view the text information.
Optionally, the first text information may also be generated by editing the content to be live broadcast of the target live broadcast before the target live broadcast starts. For example, for live online lecture, a lecturer may arrange lecture content into a text file of an electronic file in advance, and store the text file in the second electronic device, so that the second electronic device may send the text file to the first sub-electronic device under the condition that the first electronic device is accessed to a target live broadcast, so that the first electronic device may display the text file for viewing by a live broadcast audience.
It is understood that the first text information may be a live content outline (e.g., a general description of live content), or may be detailed live content (e.g., what the anchor user says is substantially or entirely the content in the first text information during live broadcast), and of course, specific situations may be selected according to actual requirements such as importance of live content.
Optionally, in this embodiment, in addition to the first electronic device being capable of displaying the first text information, the second electronic device is also capable of displaying the first text information.
For example, in a case where the first text information is converted from the voice information in the target live broadcast, the second electronic device may display only the first text information converted from the current voice information in the target live broadcast, or may display the first text information converted from the current voice information in the target live broadcast and also display the first text information converted from the historical voice information (i.e., the voice information before the current voice information) in the target live broadcast, so that the anchor user reviews the live broadcast content.
For example, when the first text information is generated by editing the content to be live in the target live broadcast before the start of the target live broadcast, the first text information may be displayed.
Optionally, in this embodiment of the application, when the first text information is obtained by converting from the voice information in the target live broadcast, and when the first text information obtained by converting from the current voice information in the target live broadcast is displayed, and the first text information obtained by converting from the historical voice information in the target live broadcast is also displayed, or when the first text information is generated by editing the content to be live broadcast in the target live broadcast before the target live broadcast starts, the first text information may be displayed in a scroll display manner.
In addition, in order to facilitate the anchor user to review the previous live content and view the content to be live, a target control for controlling scrolling and page turning may be further provided, for example, as shown in fig. 5, a display area 501 displays the first text information 502 in a scrolling display manner, a slider 503 for controlling scrolling and page turning is displayed on the right side of the display area 501, the slider 503 is dragged upwards to turn the page, and the slider 503 is dragged downwards to turn the page downwards. Of course, the first text information may also be displayed in other display manners, and the specific situation may be set according to actual requirements.
When the first text information is displayed in a rolling display mode, if the target text information matched with the current voice information in the target live broadcast is not displayed, the target text information can be automatically rolled and displayed. In addition, the first text information can display a sentence in each line, so that the displayed content is not too much to influence the reading and viewing of the user.
Alternatively, in a case where the target live broadcast is a live video broadcast, the first text information may be displayed in a display area of the screen where the user views the live broadcast, for example, the live broadcast and the first text information may be respectively displayed in different display areas. In addition, the user can also select to display the first text information or hide the first text information according to actual requirements.
Optionally, in a case that the first text information is generated by editing a content to be live broadcast according to the target live broadcast before the target live broadcast starts, after the first text information is sent to the first electronic device, the live broadcast method may further include:
in the case where the first text information is displayed, text information corresponding to already live content and text information corresponding to content to be live are identified in the first text information, respectively.
For example, as shown in fig. 5, as for the text information "aaaaaaa" corresponding to the live content, the live content is represented by a tick mark on the right side thereof; the text information "bbbbbb" corresponding to the content to be live broadcast indicates the content to be live broadcast by adding underlines below the text information, so that the anchor user can conveniently check the content and the anchor user can be reminded.
Optionally, in a case where the first text information is generated by editing the content to be live broadcast of the target live broadcast before the target live broadcast starts, in step 102: after the first text message is sent to the first electronic device, the live broadcasting method may further include:
under the condition that current voice information in target live broadcast is matched with target text information in first text information, sending a target index value of the target text information to first electronic equipment; and under the condition that the current voice information in the target live broadcast is not matched with the target text information in the first text information, sending the second text information obtained by converting the current voice information to the first electronic equipment and adding the second text information to the target position in the locally stored first text information.
The target position is after the text information corresponding to the voice information before the current voice information.
In the embodiment of the application, the second electronic device can match the current voice information in the target live broadcast with the text content in the first text information in the live broadcast process.
If the corresponding text content (i.e. the target text information) is matched, the index value of the text content in the first text information (corresponding to the target index value, i.e. the specific position in the first text information, such as the information of the line number, the column number, etc.) may be sent to the first electronic device. The first electronic device searches the text content in the first text information according to the received index value, and marks the searched text content, so that a user watching the live broadcast can obtain the current live broadcast content in time according to the first text information, or timely position the corresponding text content in the first text information according to the live broadcast content. The specific marking manner is described in the foregoing, and is not described herein again.
If the corresponding text content is not matched, the text information obtained by converting the current voice information (hereinafter referred to as second text information, which is text information not included in the first text information) may be sent to the first electronic device. And the first electronic equipment receives the second text information sent by the second electronic equipment, and adds the received second text information to the target position in the first text information to become a part of the first text information for the user to view. Meanwhile, the second electronic device may also add the second text information to the target position in the locally stored first text information for storage.
Optionally, in this embodiment of the application, data transmission (for example, transmission of data such as a video stream, an audio stream, first text information, second text information, a target index value, and the like) between the first electronic device and the second electronic device may be implemented by a target server (for example, a video live broadcast server, an audio live broadcast server, and the like).
For example, as shown in fig. 3, the second electronic device as a live source may transmit text data (such as the first text information, the second text information, and the like) and a video stream and an audio stream at the time of live to the target server. And the target server sends the received text data and the video stream and the audio stream during live broadcasting to each piece of first electronic equipment serving as a live broadcasting access party. Wherein the text data is transmitted over TCP and the video stream and the audio stream are transmitted over UDP.
When the first text information is generated by editing the content to be live broadcast of the target live broadcast before the target live broadcast starts, the anchor user who performs the target live broadcast can upload the first text information to the target server through the second electronic device in advance before the target live broadcast starts. When the first electronic equipment is accessed to the target live broadcast, the target server issues first text information uploaded in advance by the anchor user to each first electronic equipment so as to be checked by a user watching the target live broadcast.
Finally, in order to better understand the live broadcasting method provided by the embodiment of the present application, the following takes live video teaching as an example to further explain the embodiment of the present application.
As shown in fig. 6, a lecturer, which is a main broadcasting user of a live video lecture, may upload an electronic text lecture of the live video lecture to a live video server through a live broadcasting device (corresponding to a second electronic device) before the live broadcasting starts. When each live broadcast access party (or the live broadcast participant corresponding to the first electronic device) accesses the video live broadcast, the video server issues the text lecture manuscript of the video live broadcast to each live broadcast access party. According to the content, the live broadcast source, the server and all the live broadcast access parties can acquire the same text lecture.
In the course of live video teaching, as shown in fig. 3, the live broadcast access party displays the received text lecture contents in the form of a list of sentences in each line. Similarly, as shown in fig. 5, the live source may also display the text lecture content prepared in advance in a list form in which a sentence is displayed in each line, so that the lecturer can better view the lecture content and give lessons with reference to the text lecture content.
In the process of live video teaching, an application program in the live broadcasting equipment can match the collected voice data with the text content in the text lecture manuscript prepared in advance.
And if the corresponding text content is matched in the text lecture, the live broadcast equipment reports the text index value of the text content to a video live broadcast server. And the video live broadcast server issues the text index value to all live broadcast access parties, and the live broadcast access parties inquire corresponding text contents from the text lecture according to the text index value and highlight the searched text contents so as to facilitate the user to check. Meanwhile, the lecture list at the live source automatically rolls to the next sentence of content, so that the lecturer can conveniently perform the lecture of the content.
And if the corresponding text content is not matched in the text lecture, the live broadcast equipment reports the text data obtained by converting the voice data to a video live broadcast server. And the video live broadcast server transmits the text data to all live broadcast access parties. And the live broadcast access party inserts the received text data into the text lecture and displays the text data in a list form. Meanwhile, the live broadcast equipment can also insert the text data into a locally stored text lecture and display the text lecture in a list form.
At the live source, the instructor can view already taught content and content to be taught from the text lecture list. Wherein, the already taught content and the content to be taught are respectively identified in the list for the instructor to distinguish.
In the live broadcast access party, the up-and-down rolling page turning of the text lecture contents can be controlled through the sliding block, so that the contents of the previous lectures of the lecturer can be reviewed at any time, and the comprehension is deepened; or look at the contents to be taught and carry out preview in advance.
In summary, in the embodiment of the present application, on the basis of live broadcasting original video data and/or audio data, one path of subtitle data of a plain text is added, and because a transmission mode adopted by the text data is more reliable, even if packet loss of the live video data and/or audio data is seriously blocked due to a network with poor signal quality, and live broadcast content cannot be clearly listened, live broadcast content can still be known by reading subtitle information (i.e., text information) in a screen, and live broadcast quality and effect are improved.
