(2) The replacement service validation data table 3100 is retrieved at regular time from the loading replacement information 2100, the channel number that has not generated the thread of the replacement film module 2200 is screened out first, the thread (channel ID thread) is automatically generated by using the channel number as the ID, and the channel ID thread is notified whether to continue or pause according to the channel number and the content of the channel replacement service flag. (3) And retrieving the unprocessed channel replacement film information in the replacement information data table 3200 at regular time, inquiring whether the advertisement HLS website in the information exists in the replacement film information set 2300, if not, retrieving the advertisement segment index list through the advertisement HLS website respectively, and establishing a new list in the replacement film information set 2300.
The advertisement repeat times of the information are used to automatically calculate and generate replacement condition information, which is stored in the replacement condition set 2250. (4) When the channel ID thread receives the start command, it will inform the download channel segment m3u 82210 to execute the program; when the channel ID thread receives the pause command, it notifies the downloaded channel segment m3u 82210 to pause the program. (5) The downloaded channel segment m3u 82210 reads the segment index file of each image quality through the HLS website, queries the channel segment queue 2260 for whether new segment information is generated and is not repeated, converts the new segment information into segment information with a time stamp and stores the segment information in the channel segment queue 2260 if the new segment information is generated and the replacement condition 2220 is notified to perform replacement condition judgment. And (4) jumping to the step (4) to continue the processing whether new segmentation information is generated or not.
Monitoring the replacement condition 2220, see fig. 3, for the following steps:
s300: executing a monitoring replacement condition;
s301: whether the execution state is starting;
s302: whether the replacement advertisement tag is "" non-replacement "";
s303: taking out the latest time stamp HLS subsection information to query the replacement condition set;
s304: whether the time conditions of the start and the end of the advertisement are met;
s305: setting the advertisement mark as "" replacement "", and extracting the current replacement film information;
s306: the notification replacement advertisement processing module processes; and
s307: the execution state is set to pause.
When the replacement advertisement status is "non-replacement", the latest HLS segment information with the timestamp is fetched from the channel segment queue 2260, the replacement condition set 2250 is queried to determine whether the condition of the advertisement is met, if the condition of the advertisement is met, the replacement advertisement status is "replacement", and then current replacement movie information is fetched from the replacement movie information set 2300. The replacement ad process 2230 is then notified whether the ad is eligible or not.
The advertisement process 2230 may perform various functions depending on the contents of the displaced advertisement status and the last generated HLS segment index information set 2241: (1) when the replacement advertisement status is "not replaced", the removal flag is set to true, please refer to fig. 4, and the following steps are performed:
s400: replacement advertisement processing commences;
s401: whether the execution state is starting;
s402: whether the replacement advertisement tag is "" non-replacement "";
s403: taking out the latest time stamp HLS subsection information;
s404: the call replacement film output module generates a destination segment index m3u8 file;
s405: removing HLS segmentation information of a first channel in a channel segmentation queue; and
s406: the execution state is set to pause.
The latest HLS segment information of one channel is fetched from the channel segment queue 2260, and is transmitted to the film replacement output 2240 to update the content of the HLS segment index information set 2241, so as to generate the target segment index m3u8 (without advertisement), remove the HLS segment information of the first channel in the channel segment queue 2260, and wait for the next instruction. (2) When the advertisement replacement status is "replacement" (step S500), please refer to fig. 5, first calculate the number of compensated segments (step S501), set the removal flag to true, call the replacement film output 2240, remove the first piece of film segment information and add an advertisement segment file name information to the HLS segment index information set 22410 according to the removal flag, add 1 to the advertisement segment COUNT, and set COUNT to the number of compensated segments minus 1 (step S502), whether to execute the advertisement insertion process of dynamically pre-adjusting the minimum segment time difference mechanism, and determine whether three conditions are satisfied simultaneously (i) the advertisement segment COUNT is smaller than the number of advertisement segments; the number of the remaining advertisement segments is less than (3 times the number of the compensation segments); ③ and COUNT is not equal to zero (step S503); if the three conditions are not satisfied, jumping to step S506 to continue execution; if the three conditions are satisfied simultaneously, the advertisement insertion process of the mechanism for dynamically pre-adjusting the minimum segment time difference is started, the removal flag is set to false, the call replacement film output module newly adds an advertisement segment message to the HLS segment index message set 2241, generates the destination segment index m3u8 according to the content, decrements COUNT by 1 and increments advertisement segment COUNT by 1, and after waiting for the second time of the advertisement segment film, jumps to step S503 to continue execution (step S504). Calling the replacement film output 2240 to generate a target segment index m3u8 file according to the contents of the HLS segment index information set 2241 (step S505), determining whether the advertisement replacement is completed, when the advertisement segment count is less than the number of advertisement segment films (step S506), and when the condition is not satisfied, after waiting for the second time of the first segment film of the HLS segment index information set 2241, jumping to step S502 to continue execution (step S507); when the conditions are satisfied, the channel segment queue 2260 is synchronized and the HLS segment index information set 2241 is updated, and the replacement advertisement status is changed to "wait for replacement to complete", and the process skips to step S600 to continue (step S508).
The synchronized channel segment queue 2260 is configured to change the timestamp of the last message in the channel segment queue 2260 to the current timestamp; and correcting the time stamp of the penultimate information, and deleting the queue until only the last two information are left.
(3) When the replacement advertisement status is "waiting for replacement completion", referring to fig. 6, it is first determined whether the replacement advertisement flag is "waiting for replacement completion" (step S600), the number of seconds of the first segment movie of HLS segment index information set 2241 is waited for, and COUNT is set to the number of compensated segments minus 1 (step S601), the removal flag is set to true, the call replacement movie output 2240 removes the first segment movie information of HLS segment index information set 2241, and fetches the first segment HLS segment information from channel segment queue 2260 to be added to HLS segment index information set 2241, and each time the replacement advertisement status is just switched to "waiting for replacement completion", an EXT-X-relation TAG is added to generate a destination segment index m3u8 file (step S602), it is determined whether to perform an advertisement removal process of dynamically pre-adjusting the minimum segment time difference mechanism, and it is queried whether the first segment of HLS segment index information set is advertisement information and COUNT is COUNT for the replacement advertisement output 2240 Zero, if the condition is satisfied, starting the advertisement removing process of the mechanism for dynamically pre-adjusting the minimum segment time difference, if the condition is not satisfied, jumping to step S605 to execute (step S603), executing the advertisement removing process of the mechanism for dynamically pre-adjusting the minimum segment time difference, calling the replacement film output 2240 to only move out the first piece of segment information of the HLS segment index information set 2241, generating the destination segment index m3u8, decreasing COUNT by 1, determining whether the removed first piece of information is an advertisement and COUNT is not zero, if the condition is satisfied, waiting for the time of seconds of the information, jumping to step S603 to continue executing, if the condition is not satisfied, jumping to step S605 to execute (S604), determining whether the first piece of information of the HLS segment index information set 2241 is an advertisement, if the first piece is an advertisement, jumping to step S601 to continue executing, if the first piece is not an advertisement, jumping to step S606 to execute (S605), changing the replacement advertisement state to 'non-replacement' and removing the replacement condition, execution of a notification of the monitoring replacement condition 2220 is awaited (step S606). The replacement movie output 2240 updates the record of the HLS segment index information set 2241 according to the advertisement status and the removal flag, adds the HLS address (segment movie path is absolute) to the channel segment movie in the recorded content, puts the HLS address into the HLS segment index information set 2241, and generates the segment index m3u8 for the destination of the image quality. (A) When the replacement advertisement status is "not replaced", there are two cases: (1) initializing (HLS segment index information set 2241 is empty), the module will take the first 3 pieces of information from the channel segment queue 2260, absolute segment movie path and store it in the HLS segment index information set 2241, and generate the destination master m3u8 file 2410 of the channel and the destination segment index m3u8 file 2420 of the image quality. (2) For update (HLS segment index information set 2241 has contents), the module will first extract the latest information from the channel segment queue 2260, after absolute segmentation of the movie path, store it in the HLS segment index information set 2241 and remove the first information, and then generate the target segment index m3u8 file of the image quality. (B) When the replacement advertisement status is "replacement", the first information of the HLS segment index information set 2241 can be selectively removed or added to retrieve the first information from the channel segment queue 2260 according to the input parameters. And the advertisement segment count is an index to obtain the information of the advertisement segment film from the current replacement film list, and after the information is put into an HLS segment index information set 2241 to generate a target segment index m3u8 of the image quality, the advertisement segment count value is added by 1, and the first segment film second number of the segment index is returned. (C) When the advertisement status of the replacement is "waiting for replacement to be completed", the first information of the HLS segment index information set 2241 can be selectively removed or added to the channel segment queue 2260 to retrieve the first information according to the input parameters.
Example (embodiment)
Referring to the flow chart of the linear channel replacement film system in fig. 2, it is assumed that the contents of the replacement film service and the replacement film information provided by those channels are already inputted from the linear channel replacement film management system 1000 into the replacement service validation data table 3100 and the replacement information data table 3200 of the replacement information database 3000, respectively.
The contents of the replacement service validation data table 3100 are as follows:
firstly, a customized advertisement is given to a single user, wherein the contents of the replacement information data table 3200 are as follows:
1. generate and start the thread of the replace film module 2200; periodically retrieve the contents of replacement service validation table 3100 and query with chNo for the presence of a corresponding thread of replacement movie module 2200, if no thread of replacement movie module 2200 is generated that passes the chNo ID. In this example, there are two IDs: ID15 and ID16 replace movie module threads generated, only the replace service flag of ID15 is enabled.
2. Newly-added replacement film information and newly-added replacement conditions: after the new replacement information in the replacement information data table 3200 is periodically retrieved,
2-1, firstly, inquiring the value of the adLink via the replacement film information set 2300 to judge whether there is repeated replacement information, if not, retrieving a replacement film segment index list (adList) through the website of the replacement film recorded by the adLink, analyzing one segment length (duration) of the list, and storing the information of the adLink, the adList, the adDuration and the like into the replacement film information set 2300, as follows:
2-2, retrieving the replacement movie fragment index list adID from the replacement movie information set 2300 with the addlink as ID, and generating 3 pieces of channel replacement movie information in the replacement condition set 2250 according to the replacement information repeat times of 3, wherein the addstarttime of the second piece is calculated from the first addtime, addduration and intervalDuration, 2015-12-1620: 00: 00+14Sec +300Sec 2015-12-1620: 05: 14, and so on for the third pen, and the ad given to user1 as follows:
and reading the sectional index file of each picture quality by utilizing the HLS website of the channel in the replacement service information, and storing the HLS sectional information in a channel sectional queue to inform a monitoring replacement condition module to judge replacement conditions after converting the HLS sectional information with the time stamp when new HLS sectional information of the channel exists. This step is repeated unless a wait is entered upon receipt of the pause replacement film service. The replacement advertisement status initial value is "not replaced". Assuming that the channel segmentation queue 2260 has information already, as follows
Assuming that a segment index of the image quality of the channel has new segment information generated, the contents are as follows:
and permuting the HLS segment index information set 2241 and destination segment index m3u8 files within movie output 2240 as follows:
3, the downloading channel segment m3u 82210 of ID15 thread, through the channel HLS URL scrolling to read the segment list of each image quality of the channel, and query the channel segment queue 2260 of ID15 thread to determine whether there is new segment information generated and not repeated for each image quality,
3-1. after conversion to HLS segment information with time stamp with reference to FIG. 7, an update is made to channel segment queue 2260 as follows
3-2, the updated information is taken out, and the monitoring replacement condition module 2220 is notified to judge the replacement condition.
4. The monitoring replacement condition module 2220 performs the following procedure according to the content of the replaced advertisement status, when the content is "non-replaced", the latest HLS segment information with the time stamp is taken out from the channel segment queue 2260, the replacement condition set 2250 is queried to determine whether the advertisement condition is met, and if the advertisement condition is met, the replaced advertisement status is "replaced" and the initial value of the advertisement segment index count is zero. The replacement ad process 2230 is then notified whether the ad is eligible or not.
The replacement advertisement process 2230 may perform various functions based on the replacement advertisement status and the last generated contents of the HLS segment index information set 2241:
referring to fig. 3, the sttimestamp value of the obtained update information is still 4, the ettimestamp value is etime4, and the addstarttime of the replacement condition set 2250 is compared.
4-1, assuming that the replacement condition is not satisfied, indicating that the adStartTime is not between the information still 4 and etime4, the replacement advertisement status is set to "non-replacement" (A) the replacement advertisement process 2230 performs "non-replacement" process, referring to FIG. 4, the call replacement movie output 2240 generates a destination segment index m3u8 containing the name of user1 according to the contents of the HLS segment index information set 2241; example (c): user1index.m3u8), the second number of the first segmented film which is returned and output by m3u8 is 4.11 seconds (the second number of the segments is 4 seconds), as follows:
after waiting 4 seconds, when the next channel segment m3u 82210 has new segment information generated, remove the first data in the channel segment queue 2260 and update the contents of the HLS segment index information set 2241:
4-2, assuming that the replacement condition is satisfied, representing that the adStartTime is between the pieces of information still 4 and etime4, the replacement advertisement status is set to "replacement", and the advertisement segment count value is set to 0.
(B) The replacement advertisement process 2230 performs a "replacement" process, referring to fig. 5, to obtain that the number of calculated compensated segments is 2, call the replacement movie output 2240, generate a destination segment index m3u8 file, add EXT-X-disarmingtytytateg to the file, so that the mobile intelligent terminal device 5000 can normally play the advertisement movie from the channel program, and return the first segment movie with the second number of 4.11 seconds (the segment second number is an integer of 4 seconds), as follows:
there are 7 commercial segment films in the "adList" in this example, and it is judged that the commercial replacement is not completed, and after waiting for 4 seconds of segment seconds,
referring to fig. 5, after S502-S504, the mechanism for dynamically pre-adjusting the minimum segment time difference is activated, and after the mechanism processes the movie output 2240 to insert two advertisement segment filenames into the HLS segment index information set 2241 and the generation destination segment index m3u8, the advertisement segment count is 3, and the number of the remaining advertisement segment movies is 4, as follows:
judging whether the advertisement segment count is 3 or less than 7 in S506, finding that the advertisement has not been replaced, after S502-S504, generating a target segment index m3u8 file, the advertisement segment count is 5, and the number of the remaining advertisement segment films is 2, as follows:
after waiting for 2 seconds again, it is determined whether the advertisement segment count is 5 or less than the advertisement segment film number of 7, S502 to S504 are performed, the advertisement segment count is 7, and the number of the remaining advertisement segment films is zero, as follows:
judging that the advertisement segment count 7 is equal to the advertisement segment film number 7 according to S506, synchronizing the channel segment queue 2260, and changing the time stamp of the last piece of information in the channel segment queue 2260 to the current time stamp; and correcting the timestamp of the penultimate information, deleting the queue until only the last two pieces of information remain, updating the HLS segment index information set 2241 and replacing the advertisement status to 'wait for replacement complete', jumping to the replacement advertisement process 2230 for continued execution as follows
(C) When the replacement advertisement status is "waiting for replacement completion", referring to fig. 6, after waiting for 2 seconds, setting COUNT to be the number of compensated segments minus 1, calling the replacement film output 2240 to remove the first segment ad2.ts film of the HLS segment index information set 2241 and add the first segment HLS segment information N-1.ts taken from the channel segment queue 2260, generating the destination segment index m3u8 file as follows:
is it determined whether to perform the remove advertisement process of the dynamic pre-adjust segment time difference mechanism? Because the first of the HLS segment index information set is advertisement information and the COUNT is 1, the judgment is true, the advertisement removing process of the mechanism for dynamically pre-adjusting the minimum segment time difference is started,
moving out HLS segment index information set 2241, first segment information ad3.ts, and COUNT decreasing by 1, to generate destination segment index m3u8, as follows:
the query determines whether the first piece of information in the HLS segment index information set 2241 is an advertisement, and the first piece of information is ad4.ts advertisement information but COUNT is zero, so the advertisement removal process of the mechanism of dynamically pre-adjusting the minimum segment time difference is left.
