The embodiment provides a live broadcast-to-on-demand method which can convert live broadcast content into on-demand content in a segmented manner and can perform various nonlinear edits on the converted on-demand content.
The embodiment of the invention also provides another live broadcast-to-on-demand method, which comprises the following steps:

Each segmented on-demand file consists of a file header and a file body, wherein the file header is used for recording file information, and the file body is used for recording live broadcast content.
Specifically, the header records transcoding parameters, the start time, the end time, and the duration of a video, where the video refers to live content recorded in the file body. In step S204, the segmented on-demand files may be spliced according to the information in the file header to obtain a complete on-demand file recorded with complete live content.
The embodiment of the invention also provides a live broadcast-to-on-demand broadcast method, which comprises the following steps:

and if the live broadcast time reaches the first video segmentation time point, generating a first segmented on-demand file packet according to the live broadcast content between the live broadcast start and the first video segmentation time point.
And if the live broadcast time reaches the ith (i is more than 1) video segmentation time point, generating an ith segmented on-demand file packet according to the live broadcast content between the ith-1 video segmentation time point and the ith video segmentation time point.
In this embodiment, taking live broadcasting with a broadcasting time of 90 minutes as an example, if the video segmentation time points are 85 minutes and 90 th minute, then:
when the live broadcast is carried out for 85 minutes, generating a first segmented video-on-demand file package named vid1 according to the live broadcast content between 0 minute 0 second and 85 minute 0 second;
when the live broadcast is finished, a second segmented video-on-demand file package named vid2 is generated according to the live broadcast content between 85 minutes 0 second and 90 minutes 0 second.
In this embodiment, taking on-demand files providing four kinds of definitions, namely smooth, standard definition, high definition and super definition, as an example, each segmented on-demand file packet includes four segmented on-demand files, and the four segmented on-demand files all record the same content but are obtained from different transcoding parameters; correspondingly, in step S304, the segmented on-demand files with the same transcoding parameters are spliced to finally generate four complete on-demand files, and the four complete on-demand files respectively correspond to four definitions of smoothness, standard definition, high definition and super definition.
Specifically, S304, as shown in fig. 2, includes:
s3041, obtaining a segmented on-demand file packet for recording live broadcast contents in different time periods.
In this embodiment, the segmented on-demand file package recording the live content in different time segments may be obtained in different manners, such as copying or downloading. In this embodiment, a first segmented on-demand file package vid1 and a second segmented on-demand file package vid2 are obtained. Each segmented on-demand package has four files.
S3042, selecting a segmented on-demand file from each segmented on-demand file packet as a file to be spliced; the files to be spliced all have the same transcoding parameters.

Further, the integrated on-demand file obtained after combination is subjected to fluidization, and the integrated on-demand file subjected to fluidization is stored;
in addition, after the complete on-demand file subjected to the streaming processing is obtained, the segmented on-demand file in the segmented on-demand file packet used for generating the complete on-demand file is deleted.
In this embodiment, after the complete on-demand file with smooth definition and subjected to the streaming processing is generated, two segmented on-demand files with smooth definition are deleted, and only three segmented on-demand files remain in both the vid1 and the vid 2.
S3044, judging whether segmented on-demand files which do not participate in splicing exist.
S3045, if yes, repeating the steps to continue to generate the next complete on-demand file.
In this embodiment, the steps of S3041-S3043 need to be repeated three times to generate a complete on-demand file with standard definition, high definition and super definition; accordingly, the segmented on-demand files with standard definition, high definition and ultra definition are deleted. Only when both of the reserved vid1 and vid2 are empty, the segmented on-demand file packages vid1 and vid2 are deleted, and S304 ends.
Specifically, in this embodiment, in step S303, the segment-on-demand file may be released first, and after the vid1 is generated, the vid1 may be released to the user.
Although not the entire live content is recorded in the vid1, most live content has been recorded, and vid1 may be released in advance to meet the user's need to review live content as soon as possible. After the vid1 is released, the user can view the on-demand video recorded with the live content, and in the process of viewing by the user, the S304 synchronously splices the segmented on-demand files.
And deleting the segmented on-demand files in the first segmented on-demand file packet which is published before, and re-publishing the complete on-demand file. The method for realizing the republishing in the embodiment comprises the following steps:
when the segmented on-demand file packages vid1 and vid2 are deleted, four complete on-demand files with the definitions of smooth, standard definition, high definition and super definition are generated. The package of files named vid1, which includes the four complete on-demand files described above, is regenerated and vid1 is published to the user.
In this embodiment, the file packages issued twice are all vid1, and the names are consistent because, if the user is watching a video using the vid1 file package which is issued first and contains the segmented on-demand file, after issuing the vid1 file package containing the complete on-demand file, the user only needs to perform a refresh operation, the server can provide a complete video service for the user using the vid1 file package containing the complete on-demand file, the playing experience of the user is not affected, and the two issues of the vid1 are imperceptible to foreground users.
The embodiment provides a live broadcast-to-on-demand method and a method for releasing on-demand files, so that a user can watch part of on-demand videos first and can easily switch to watch the complete videos, and the user experience is remarkably improved.
The embodiment of the invention also provides a live broadcast-to-on-demand broadcast method, which comprises the following steps:
s401, responding to a live broadcast to on-demand broadcast instruction, and obtaining N (N is larger than 1) video segmentation time points.
Specifically, the nth video segment time point is a live broadcast end time point.
S402, acquiring live broadcast data stream in real time and recording live broadcast time.
S403, if the live broadcast time reaches the video segmentation time point, generating a segmentation on-demand file packet according to the live broadcast content corresponding to the video segmentation time point; the segmented on-demand file package comprises one or more segmented on-demand files recorded with the same live content.
In this embodiment, taking live broadcasting with a broadcasting time of 90 minutes as an example, if the video segmentation time points are 80 minutes and 90 minutes, then:
when the live broadcast is carried out for 80 minutes, a first segmented video-on-demand file package is generated according to the live broadcast content between 0 minute 0 second and 80 minute 0 second and is named as vid 1.
When the live broadcast is finished, a second segmented video-on-demand file package named vid2 is generated according to the live broadcast content between 80 minutes 0 seconds and 90 minutes 0 seconds. Since the time required for generating the segmented on-demand package is positively correlated with the video time duration, the time consumption for generating the vid2 is far less than that of the vid 1.
In this embodiment, taking the on-demand files providing four kinds of definitions, namely smooth, standard definition, high definition and super definition, as an example, each segmented on-demand file packet includes four segmented on-demand files, and the four segmented on-demand files all record the same content but are obtained from different transcoding parameters.
Each of the segmented on-demand files comprises one or more file segments; and if the segmented on-demand file comprises a plurality of file segments, the storage sequence of the file segments in the segmented on-demand file is consistent with the sequence of the live content recorded by the file segments in the live data stream.
In this embodiment, if each file segment contains 5 minutes of video content, each segment on-demand file in vid1 contains 16 file segments, and each segment on-demand file in vid2 contains 2 file segments.
Further, if the video duration in the segmented on-demand file cannot be divided exactly by the video duration of the file segment, the remaining video length is included in the last file segment constituting the segmented on-demand file, and assuming that the video duration in the segmented on-demand file is 92 minutes, the segmented on-demand file is composed of 15 file segments containing 5 minutes of video content and the last file segment containing 7 minutes of video content.
S404, splicing the segmented on-demand files according to the time sequence of the live broadcast contents recorded by the segmented on-demand files to obtain complete on-demand files recorded with complete live broadcast contents.
In this embodiment, in step S404, the segmented on-demand files with the same transcoding parameters are spliced to finally generate four complete on-demand files, where the four complete on-demand files correspond to four definitions, namely, smooth, standard definition, high definition, and super definition.
Specifically, S404, as shown in fig. 3, includes:
s4041, obtaining a segmented on-demand file package for recording live broadcast contents in different time periods.
In this embodiment, a first segmented on-demand file package vid1 and a second segmented on-demand file package vid2 are obtained. Each segmented on-demand package has four files.
S4042, selecting a segmented on-demand file from each segmented on-demand file packet as a file to be spliced; the files to be spliced all have the same transcoding parameters.
Taking fluency as an example, the segmented on-demand files with fluency definition corresponding to the transcoding parameters in vid1 and vid2 are selected as the files to be spliced.
S4043, sorting the files to be spliced according to the time sequence of the live broadcast contents recorded by the files to be spliced.
In this embodiment, the file to be spliced in the vid1 is before, and the file to be spliced in the vid2 is after.
S4044, taking the file to be spliced arranged at the first position as a designated file, and sequentially inserting subsequent files to be spliced into the tail of the designated file in an additional mode to obtain a complete on-demand file which corresponds to the transcoding parameters and records complete live broadcast content.
Taking fluency as an example, the file to be spliced obtained in vid1 is taken as a designated file, and the file to be spliced obtained in vid2 is inserted into the tail of the designated file in an additional manner, so that a complete on-demand file containing 18 file segments is obtained.
Further, carrying out fluidization processing on the obtained complete on-demand file, and storing the fluidized complete on-demand file;
in addition, after the complete on-demand file subjected to the streaming processing is obtained, the segmented on-demand file in the segmented on-demand file packet used for generating the complete on-demand file is deleted.
In this embodiment, after the complete on-demand file with smooth definition and subjected to the streaming processing is generated, two segmented on-demand files with smooth definition are deleted, and only three segmented on-demand files remain in both the vid1 and the vid 2.
S4045, judging whether segmented on-demand files which do not participate in splicing exist.
S4046, if yes, repeating the steps to continue to generate the next complete on-demand file.
In this embodiment, the steps of S4041-S4044 need to be repeated three times to generate a complete on-demand file with standard definition, high definition, and super definition; accordingly, the segmented on-demand files with standard definition, high definition and ultra definition are deleted. Only when both of the reserved vid1 and vid2 are empty, the segmented on-demand file packages vid1 and vid2 are deleted, and S404 ends.
Specifically, in this embodiment, in step S403, the segment-on-demand file may be released first, and after the vid1 is generated, the vid1 may be released to the user.
Although not the entire live content is recorded in the vid1, most live content has been recorded, and vid1 may be released in advance to meet the user's need to review live content as soon as possible. After the vid1 is released, the user can view the on-demand video recorded with the live content, and in the process of viewing by the user, S404 splices the synchronized segmented on-demand files.
And deleting the segmented on-demand files in the first segmented on-demand file packet which is published before, and re-publishing the complete on-demand file. The method for realizing the republishing in the embodiment comprises the following steps:
when the segmented on-demand file packages vid1 and vid2 are deleted, four complete on-demand files with the definitions of smooth, standard definition, high definition and super definition are generated. The package of files named vid1, which includes the four complete on-demand files described above, is regenerated and vid1 is published to the user.
Of course, other on-demand file distribution methods may also be used, such as directly distributing the complete on-demand file after obtaining the complete on-demand file recorded with the complete live content.
The embodiment provides another live broadcast-to-on-demand method, so that a user can watch part of on-demand videos first and can also easily switch to watch the complete videos, user experience is remarkably improved, and in addition, if an error occurs in the generation process of the complete on-demand file, loss can be compensated through issuing the segmented on-demand file, and fault tolerance is improved.

Those skilled in the art will appreciate that the terminal structure shown in fig. 7 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components. Wherein:
the RF circuit 110 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information from a base station and then sends the received downlink information to the one or more processors 180 for processing; in addition, data relating to uplink is transmitted to the base station. In general, the RF circuitry 110 includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, an LNA (low noise amplifier), a duplexer, and the like. In addition, the RF circuitry 110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to GSM (Global System for mobile communications), GPRS (General Packet Radio Service), CDMA (Code division multiple access), WCDMA (Wideband Code division multiple access), LTE (Long Term Evolution), email, SMS (Short Messaging Service), etc.
The memory 120 may be used to store software programs and modules, and the processor 180 executes various functional applications and data processing by operating the software programs and modules stored in the memory 120. The memory 120 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, application programs required for functions, and the like; the storage data area may store data created according to the use of the terminal, and the like. Further, the memory 120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device. Accordingly, the memory 120 may further include a memory controller to provide the processor 180 and the input unit 130 with access to the memory 120.
The input unit 130 may be used to receive input numeric or character information and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, the input unit 130 may include a touch-sensitive surface 131 as well as other input devices 132. The touch-sensitive surface 131, also referred to as a touch display screen or a touch pad, may collect touch operations by a user on or near the touch-sensitive surface 131 (e.g., operations by a user on or near the touch-sensitive surface 131 using a finger, a stylus, or any other suitable object or attachment), and drive the corresponding connection device according to a predetermined program. Alternatively, the touch sensitive surface 131 may comprise two parts, a touch detection means and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 180, and can receive and execute commands sent by the processor 180. Additionally, the touch-sensitive surface 131 may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch-sensitive surface 131, the input unit 130 may also include other input devices 132. In particular, other input devices 132 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The Display unit 140 may include a Display panel 141, and optionally, the Display panel 141 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch-sensitive surface 131 may cover the display panel 141, and when a touch operation is detected on or near the touch-sensitive surface 131, the touch operation is transmitted to the processor 180 to determine the type of the touch event, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event. Although in FIG. 5, touch-sensitive surface 131 and display panel 141 are shown as two separate components to implement input and output functions, in some embodiments, touch-sensitive surface 131 may be integrated with display panel 141 to implement input and output functions.
The terminal may also include at least one sensor 150, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 141 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 141 and/or a backlight when the terminal is moved to the ear. As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), detect the magnitude and direction of gravity when the terminal is stationary, and can be used for applications of recognizing terminal gestures (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured in the terminal, detailed description is omitted here.
Audio circuitry 160, speaker 161, microphone 162 may provide an audio interface between a user and the terminal. The audio circuit 160 may transmit the electrical signal converted from the received audio data to the speaker 161, and convert the electrical signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signal into an electric signal, converts the electric signal into audio data after being received by the audio circuit 160, and then outputs the audio data to the processor 180 for processing, and then to the RF circuit 110 to be transmitted to, for example, another terminal, or outputs the audio data to the memory 120 for further processing. The audio circuit 160 may also include an earbud jack to provide communication of peripheral headphones with the terminal.
WiFi belongs to a short-distance wireless transmission technology, and the terminal can help a user to send and receive e-mails, browse webpages, access streaming media and the like through the WiFi module 170, and provides wireless broadband internet access for the user. Although fig. 7 shows the WiFi module 170, it is understood that it does not belong to the essential constitution of the terminal, and may be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 180 is a control center of the terminal, connects various parts of the entire terminal using various interfaces and lines, performs various functions of the terminal and processes data by operating or executing software programs and/or modules stored in the memory 120 and calling data stored in the memory 120, thereby performing overall monitoring of the terminal. Optionally, processor 180 may include one or more processing cores; preferably, the processor 180 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 180.
The terminal also includes a power supply 190 (e.g., a battery) for powering the various components, which may preferably be logically coupled to the processor 180 via a power management system to manage charging, discharging, and power consumption management functions via the power management system. The power supply 190 may also include any component including one or more of a dc or ac power source, a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator, and the like.
