Description

A method and device for realizing live broadcast time shift

technical field

The invention relates to the field of multimedia Internet, in particular to a method and device for realizing time-shifting of live broadcast.

Background technique

Streaming media application is a kind of multimedia application developed from the network, that is, using streaming to transmit multimedia files on the network, including audio, video and Flash animation. The main feature of streaming media transmission technology is to transmit multimedia data in the form of stream. After compressing the continuous image and sound information and putting them on the network server, the client does not need to download the entire media file before playing, but plays the received information in the buffer area at the same time. The rest will be continuously downloaded from the server to the client, that is, "play while downloading". In this way, it is avoided that the user needs to spend a period of time to download the complete file to the client when watching or listening to the media stream, which can bring the user a "real-time playback" service-aware experience.

According to the sources of streaming media programs, they can be divided into stored programs and live programs: the program sources of stored programs are generally from stored files, and are provided by diabolical services such as streaming media services in this way. The program client can perform operations such as positioning, fast forward, and fast rewind during playback; while live programs generally come from live sources, such as live broadcasts or broadcast TV, etc., such programs are usually non-rewindable. The data source of the live broadcast is generally real-time, such as a live broadcast of a football game, no matter when the user enters the system, the content they see is basically synchronized with the data source.

Live time-shifting is a personalized service based on live TV. Compared with traditional digital TV, live time-shifting allows users to pause and rewind programs while watching live TV programs. For programs that have already been broadcast, Within the range of live time-shift playback supported by the time-shift server, playback from any point in time and fast forward and rewind of various multiples can be realized. Within the range of live broadcast time-shifting supported by the time-shifting server, users are no longer bound by a fixed program schedule, and can fully control the broadcasting of programs.

In the prior art, when the user is watching the time-shifting live broadcast, the current user usually determines the current viewing position by displaying a progress bar. However, the existing progress bar cannot display the relevant information of the program, and the user cannot know the time-shifted programs of the live broadcast, which reduces the user experience.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

An embodiment of the present invention provides a method for realizing live broadcast time shift, as shown in FIG. 1 , including:

Step 101: Determine the live broadcast time, time-shift duration, and determine the time-shift time according to the live broadcast time and time-shift duration.

Specifically, HLS ((HTTPLiveStreaming, streaming media based on HTTP (HyperTextTransferProtocol, Hypertext Transfer Protocol) protocol) protocol) is used as the transmission protocol of live content in the device realizing live time shifting. The device realizing live time shifting can perform data transfer in live content During transmission, the playback file m3u8 file is obtained. Record the live broadcast time and time-shift duration in the m3u8 file. At this time, the device that realizes live broadcast time-shift can obtain the live broadcast time and time-shift duration by parsing the m3u8 file, and the device that realizes live broadcast time-shift obtains After the live broadcast time and time-shift duration, the time-shift moment can be calculated according to the live broadcast time and time-shift duration, which is the time when the time-shift starts.

Further, the time-shift duration is 4 hours.

It should be noted that the time shift duration is preset by the administrator according to actual needs. It can be set by the administrator of the server that sends the m3u8 file. At this time, the m3u8 file contains the TS (TransportStream, Transport Stream) file directory of 4 hours of live broadcast and time-shifted programs, and the end of the m3u8 file does not have the EXT-X-ENDLIST mark, where EXT-X-ENDLIST means The terminator of the m3u8 file. In this way, the device for realizing live broadcast time shifting will not process the m3u8 file as on-demand. On the server side, the device that implements live broadcast time shifting will update the m3u8 file every time a piece of live TS file is processed, that is, the latest TS file will be added to the end of the TS file directory of the m3u8 file, and the TS file 4 hours ago will be added from m3u8 file deleted. In this way, the device that realizes the time shifting of the live broadcast will request the latest live TS file every time it requests the m3u8 file. Since there is no EXT-X-ENDLIST mark, the device that implements live time shifting will keep playing without stopping.

Exemplarily, the device for implementing live broadcast time-shifting can obtain the m3u8 file through the HLS protocol. If it is recorded in the m3u8 file that the live broadcast time is 11 o'clock, and the time-shift duration is 4 hours, at this time, the device that realizes the live broadcast time-shift can analyze the m3u8 file after obtaining the m3u8 file, and then obtain the recorded time in the m3u8 file The live broadcast time shifts in time. The device for realizing the time shift of the live broadcast can shift the time in time by 4 hours according to the acquired live broadcast time of 11 o'clock, and determine the time shift time as 7 o'clock.

Step 102, acquiring a program menu.

Wherein, the relevant information of each program of the current channel is recorded in the program menu, including program name and program start time.

Specifically, the device for realizing live broadcast time shifting can obtain the program menu of the current channel. At this time, when the device implementing live time shifting can cache the acquired program menu, if the device for implementing live time shifting has a program menu cached in the cache, the device implementing live time shifting can directly obtain it from its cache. At this time, the device for realizing the time-shifting of the live broadcast is not acquiring the program menu for the first time, but the acquiring after storing the program menu in the cache after acquiring the program menu through the server for the first time. Therefore, the device for implementing time-shifting of the live broadcast can obtain the program menu in the cache.

If the device implementing live time shifting obtains the program menu for the first time, or the terminal device cannot cache the program menu, the device realizing live time shifting needs to obtain the program menu from the server.

That is, obtaining the program menu includes: the device for realizing the live broadcast time-shifting sends a program menu request message to the server, and receives the program menu returned by the server. Thereby, the program menu of the current channel can be acquired.

It should be noted that, the method for obtaining the program menu by the device for realizing the time-shifting of the live broadcast may also be in other ways, which is not limited in the present invention.

It should be noted that, the related information of the program may also include other information of the program, such as the program number, the duration of the program and so on. The present invention is not limited thereto.

Further, the program menu is EPG (Electronic Program Guide, Electronic Program Guide).

It should be noted that the program menu may also be other information capable of indicating the program title and program start time of each program included in the current channel, which is not limited in the present invention.

It should be noted that the sequence between step 101 and step 102 is not limited in the present invention. Step 101 can be executed first, and then step 102 is executed; or step 102 can be executed first, and then step 101 is executed; step 101 and step 102 can also be executed simultaneously. Only one case is shown in the diagram.

As mentioned in the above example, if the user is watching channel a, the device for implementing live time shifting can acquire the program menu of channel a. Suppose, the program menu of channel a records that the program name is program A, the program start time is 6 o'clock, the program name is program B, the program start time is 7 o'clock, the program name is program C, the program start time is 9 o'clock, the program The name is program D, the program start time is 11:00, the program name is program E, and the program start time is 11:30.

Step 103: Use the time-shifting time as the start time of the progress bar and the live broadcast time as the end time of the progress bar, and determine the relevant information of the time-shifted program in the program menu according to the start time and end time of the progress bar.

Wherein, the time-shifted program refers to a program whose start time is greater than or equal to the start time of the progress bar, and whose program start time is less than or equal to the end time of the progress bar.

Specifically, the device for realizing the live broadcast time shift corresponds the progress bar to the live broadcast time shift. At this time, the time-shifting time can be used as the start time of the progress bar, and the live broadcast time can be used as the end time of the progress bar. The length of the progress bar is the time shift duration. In this way, the length of the progress bar is fixed, that is, the time-shift duration is fixed, and the live broadcast time changes with time, and at this time, the time-shift moment also changes with time. That is, the progress bar changes with time. After the progress bar is determined, according to the start time and end time of the progress bar, in the program menu, the program whose start time is greater than or equal to the start time of the progress bar and less than or equal to the end time of the progress bar can be determined as time. to move the program. Since the start time of the program is greater than or equal to the start time of the progress bar, and less than or equal to the end time of the progress bar, it is indicated that these programs are programs that need to be time-shifted by the device for realizing live time shifting. At this time, such programs can be determined as time-shifted programs . In this way, the relevant information of each time-shifted program can be determined in the program menu.

As mentioned in the above example, the device that realizes the live broadcast time shift obtains the live broadcast time of 11 o'clock, the time shift time is 4 hours, and the time shift time is 7 o'clock, and after obtaining the program menu, the time shift time of 7 o'clock can be used as the progress bar The start time of the live broadcast time is 11:00 as the end time of the progress bar. In this way, the time corresponding to the length of the progress bar is 4 hours, which is the time-shifting duration. The time-shifting program of the device for realizing live time-shifting can be represented by the progress bar. In the program menu, a program whose start time is greater than or equal to the start time of the progress bar at 7 hours and less than or equal to the end time of the progress bar at 11 hours is determined as a time-shifted program. That is, program B, program C, and program D are determined as time-shifted programs. Wherein, since the program start time of program D is 11 o'clock, and the live broadcast time is 11 o'clock, program D is a live program. Program B and Program C are time-shifted programs. The relevant information of the time-shifted program is determined from the program menu of channel a.

Step 104: According to the start time and end time of the progress bar, display the relevant information of the time-shifted program at the corresponding position of the progress bar, and update the progress bar according to the preset display rules of the progress bar.

Specifically, after determining the start time and end time of the progress bar, and determining the relevant information of the time-shifted program, the device for realizing the time-shifting of the live broadcast, since the program start time of the time-shifted program is within the time included in the progress bar, therefore The corresponding position of each time-shifted program in the progress bar can be determined according to the program start time of the time-shifted program, and then the relevant information of the time-shifted program is displayed in its corresponding position. That is to say, after the corresponding position of each time-shifted program in the progress bar is determined according to the program start time of the time-shifted program, the program name and program start time of each time-shifted program can be set in the different progress bars corresponding to each time-shifted program. displayed on the location.

Further, in order to facilitate the user to locate the progress bar, the progress bar can be represented by scales. Assuming that each scale of the progress bar corresponds to 1 second, the length of the progress bar is: time-shifting duration*60*60. When the time shifting time is 4 hours, the length of the progress bar is: 4*60*60=14400. In this way, when the relevant information of the time-shifted program is displayed on the progress bar, the scale corresponding to each time-shifted program on the progress bar can be determined according to the program start time of each time-shifted program, and then the time-shifted program's Relevant information is displayed on the scale of the corresponding progress bar.

The device for realizing live broadcast time shift needs to update the progress bar in real time according to the preset display rules of the progress bar.

Wherein, the preset display rule is that the start time and end time of the progress bar change with the change of the live program of the current channel, and the relevant information of the time-shifted program displayed in the progress bar also changes with the live broadcast of the current channel. The program changes.

That is to say, since the length of the progress bar remains unchanged, that is, the duration of the time shift remains unchanged, but the live broadcast time is constantly changing, so the time shifting time also changes accordingly. In this way, the start time and The end time varies with time. At this time, when updating the progress bar, the device for live broadcasting in real time may update it according to the above steps 101-104. That is, to re-execute steps 101-104 to update the progress bar.

Since the start time and end time of the progress bar change with time, the positions of the relevant information of each time-shifted program represented on the progress bar also change with time.

As described in the above example, the device that realizes the time shift of the live broadcast takes the time shift time 7 o'clock as the start time of the progress bar, and the live broadcast time 11 o'clock as the end time of the progress bar, and determines the time of program B, program C and program D After shifting the program, 1 second is used as a scale of the progress bar, and then the progress bar can be divided into 4*60*60=14400 scales. The device for realizing live broadcast time-shifting can know that the program start time of program B is 7 o'clock in the relevant information of the time-shifted program. At this time, the device for realizing live broadcast time-shifting can determine that the scale of the progress bar corresponding to program B is the first The scale is the starting position of program B on the progress bar. The program start time of program C is 9 o'clock. At this time, the device for implementing live broadcast time shift can determine that the scale of the progress bar corresponding to program C is the 7200th scale, that is, program C is at the middlemost position of the progress bar. The program start time of program D is 11 o'clock. At this time, the device for realizing live broadcast time shift can determine that the scale of the progress bar corresponding to program D is the 14400th scale. Program D is a live program, so that program D is at the end position of the progress bar . After determining the corresponding position of each time-shifted program on the progress bar, the device for realizing live broadcast time-shifting can display the relevant information of each time-shifted program at its corresponding position, that is, the program name and program name of program B The start time is displayed at the beginning position of the progress bar, the program name and program start time of program C are displayed at the middle position of the progress bar, and the program name and program start time of program D are displayed at the end position of the progress bar, as shown in picture 2.

Further, after the device for realizing time-shifting of the live broadcast displays the relevant information of the time-shifted program on the progress bar, since the length of the progress bar remains unchanged, the live broadcast time changes with time, so the start time of the progress bar also changes with time. change with time. In this way, the relevant information of each time-shifted program displayed on the progress bar also changes with time. Assuming that the current live broadcast time is 11:30, the method for updating the progress bar of the device that realizes live broadcast time shift is as follows:

The device for realizing the live broadcast time shift determines the time shift time as 7:30 according to the live broadcast time of 11:30 and the time shift time. The time-shift time 7:30 is used as the start time of the progress bar, and the live broadcast time is 11:30 as the end time of the progress bar. In the obtained program menu, it is determined that the program whose start time is greater than or equal to 7:30 and less than or equal to 11:30 is program C whose program start time is 9 o'clock, program D and program whose program start time is 11 o'clock Program E starting at 11:30. Therefore, program C, program D and program E can be determined as time-shifted programs. The device for realizing live time shifting can determine the position in the progress bar corresponding to each time-shifting program according to the start time and end time of the progress bar, and the program start time of each time-shifting program, and then the position of each time-shifting program can be Relevant information is displayed at different positions of the progress bar, as shown in Figure 3.

The device for implementing live time shifting can update the progress bar in real time according to the above method.

Further, in order that the relevant information of each time-shifted program displayed on the progress bar does not block each other, the relevant information of the programs whose play duration is less than 30 minutes may not be displayed on the progress bar.

An embodiment of the present invention provides a method for realizing time-shifting of live broadcasting, including: determining the live broadcasting time, the time-shifting duration, and determining the time-shifting time according to the live broadcasting time and time-shifting duration; obtaining the program menu; using the time-shifting time as the progress bar Start time, take the live broadcast time as the end time of the progress bar, and determine the relevant information of the time-shifted program in the program menu according to the start time and end time of the progress bar; according to the start time and end time of the progress bar, The relevant information of the time-shifted program is displayed on the corresponding position of the progress bar, and the progress bar is updated according to the preset display rules of the progress bar. In this way, the device for implementing live broadcast time shifting can use the time shifting time as the start time of the progress bar, and use the live broadcast time as the end time of the progress bar, that is, determine the time corresponding to the progress bar. The program menu is acquired, the time-shifted program whose start time is within the time corresponding to the progress bar is determined from the program menu, and the relevant information of the time-shifted program is displayed on the corresponding position of the progress bar. Therefore, the related information of the time-shifted program is displayed on the progress bar, and the purpose of improving user experience is realized.

Further, as shown in FIG. 4, before the above-mentioned step 101 determines the live broadcast time, the time-shift duration, and according to the live broadcast time and time-shift duration, before determining the time-shift time, it also includes:

Step 105, receiving an instruction to display a progress bar.

Specifically, the progress bar of the device for realizing live broadcast time-shifting may not be displayed all the time, but may be displayed only when the user needs to display it. At this time, the device for implementing time-shifting of the live broadcast may receive an instruction to display the progress bar sent by the user.

Further, the instruction to display the progress bar is a pause instruction. That is, after receiving the pause command, the device for realizing the time-shifting of the live broadcast can pause the broadcasting of the program, and display the progress bar corresponding to the current time.

When the program is paused, the end time of the progress bar is constantly updated to the latest time as time changes, and the start time of the progress bar also changes accordingly, while the playing time does not change, that is, the playback of the program paused by the user Time does not change. However, the position of the playing time of the program on the progress bar is also updated with time. That is to say, in the paused state, the position of the playing time of the program on the progress bar keeps moving to the left until it reaches the start time of the progress bar. After the pause play time of the program is updated to the start time of the progress bar, it will change with the change of the start time of the progress bar (that is, the pause play time of the program is equal to the start time of the progress bar).

It should be noted that the instruction for displaying the progress bar may also be other instructions, such as menu instructions, etc., which is not limited in the present invention.

In this way, through step 105, the user can control whether to display the progress bar, so that when the user needs to display the progress bar, the user can send an instruction to display the progress bar to the device that realizes the live broadcast time shift, so that the device that realizes the live broadcast can correspond to the current time. The progress bar is displayed, and when it is not displayed, the device for realizing the live broadcast time shift does not display the progress bar, and the display of the progress bar will not reduce the user's viewing experience, thereby further improving the user experience.
