Description

Linear channel replacement film system and method thereof

The present invention relates to a linear channel replacement film system and method thereof, and more particularly to a linear channel replacement film system and method for providing customized advertisements for each user and inserting advertisements in encrypted channel programs.

At present, the common linear channel insertion method is to adopt the practice of giving each user the same advertisement. If you want to achieve a customized and targeted advertising video service for each user, the current live channel service uses HLS streaming. A single linear channel needs to provide n profiles of audio and video files at the same time. 3 ts, if there are m users, you need 3 times to n times m times the storage space to store the HLS single linear channel program content of m users, plus k linear channels, then you need 3 multiply n by the large storage space of m times k times to store the HLS program content of k linear channels. This method needs to continuously analyze the content of the live channel program, find out whether there is a Digital Cue Tone mark, and then withdraw from the original The GOP information is replaced by an advertisement I-GOP, which generates a new live channel program file, which is quite computationally expensive and cannot be inserted into the encrypted channel program. Therefore, it is not possible to give each user a custom advertisement and the disadvantage of being unable to insert an advertisement in an encrypted channel program.

In view of the above-mentioned problems of the prior art, the object of the present invention is to provide a linear channel replacement film system and a method thereof, to solve the problem that the prior art cannot provide a customized advertisement for each user and cannot insert an advertisement into an encrypted channel program. Shortcomings.

The linear channel replacement film system of the present invention comprises a replacement information database, a channel archive, a replacement movie system and at least one mobile terminal device. The replacement information database stores a plurality of replacement information; the channel archive stores a plurality of advertisement video files; the replacement video system connects the replacement information database and the channel archive, and replaces the video according to the replacement information and the video file; the mobile terminal device according to the replacement video The movie and the video file are played in the order in which the system is scheduled to play.

The linear channel replacement video method of the present invention comprises the steps of: storing a plurality of replacement information in a replacement information database; storing a plurality of advertisement video files in a channel archive; replacing the information database and the channel archive by replacing the video system connection, and The replacement information and the video file are used to replace the video; and the mobile terminal device plays the video and the advertising video file according to the sequence of the video playback scheduled by the replacement video system.

As described above, the linear channel replacement film system and method thereof according to the present invention may have one or more of the following advantages:

1. The present invention utilizes the segmentation segment of the advertisement into the live channel program segmentation index m3u8, which can be customized to the user when viewing the channel program.

2. The invention solves the shortcoming that the current live channel insertion advertisement cannot insert an advertisement in the encrypted channel program, and allows the user to watch the encrypted or clear live channel program. Give the user a customized advertisement.

3. The technology has a mechanism for dynamically pre-adjusting the minimum segmentation time difference, and is used to solve the problem that the update frequency of the live channel m3u8 file on the CDN is not a fixed value and the minimum segmentation time length of the program with the linear channel is not necessarily the minimum score of the advertising film. The length of the segment is an integer multiple, which causes the screen to pause and be interrupted when viewed by the user.

Referring to the system flow chart of FIG. 2, (1) the linear channel replacement video management system 1000 allows the administrator to edit the replacement service information and the channel replacement video information through the web interface, and store the information in the replacement service data library 3000 replacement service effective data table. 3100 and replacement information sheet 3200. (2) The replacement service information table 3100 is periodically retrieved by loading the replacement information 2100, and the channel number of the thread of the replacement movie module 2200 has not been generated, and the thread is automatically generated by using the channel number as the ID (channel ID execution) Thread), according to each channel number and channel replacement service mark content, respectively, to inform the channel ID thread to continue execution or pause. (3) and periodically retrieving the unprocessed channel replacement video information in the replacement information data table 3200, and querying the advertisement HLS website in the information for a pen-for-replacement video information set 2300 to check whether the existing information exists, if there is no first to pass the advertisement HLS The URL retrieves the ad segmentation index list and creates a new list in the replacement video information set 2300.

The replacement condition information is automatically stored in the replacement condition set 2250 by automatically calculating the number of advertisement repetitions using the information. (4) When the channel ID thread receives the start command, it will notify the download channel segment m3u8 2210 to execute the program; when the channel ID thread receives the pause command, it will notify the download channel segment m3u8 2210 to suspend the program. (5) The download channel segment m3u8 2210 reads the segment index file of each image quality through the channel HLS web address, and queries the channel segmentation queue 2260 whether new segment information is generated and is not repeated, if there is a new message The segmentation information is converted into time-stamped segmentation information and stored in the channel segmentation queue 2260, and the monitoring replacement condition 2220 is notified to perform the replacement condition determination. Regardless of whether new segmentation information is generated or not, skip to step (4) to continue the processing.

Monitoring the replacement condition 2220, referring to FIG. 3, the steps are as follows: S300: performing a monitoring replacement condition; S301: whether the execution status is started; S302: whether the replacement advertisement flag is "non-replacement"; S303: taking out the latest time stamp HLS segment information Querying the replacement condition set; S304: whether the time condition of the start and end of the advertisement is met; S305: setting the advertisement mark to "replacement", taking out the current replacement movie information; S306: notifying the replacement advertisement processing module processing; and S307: executing state Set to pause.

Wherein, when the replacement advertisement status is "non-replacement", the latest time-stamped HLS segmentation information is retrieved from the channel segmentation queue 2260, and the replacement condition set 2250 is queried to determine whether the advertisement condition is met, and if the advertisement condition is met, The replacement advertisement status is "Replacement", and then the current replacement movie information is taken out from the replacement movie information set 2300. The replacement advertisement processing 2230 is then notified regardless of whether or not the conditions of the advertisement are met.

The advertisement processing 2230 judges to perform different functions according to the content of the replacement advertisement status and the content of the last generated HLS segmentation index information set 2241: (1) When the replacement advertisement status is "non-replacement", the removal flag is set to true, Referring to FIG. 4, the steps are as follows: S400: replacement advertisement processing starts; S401: whether the execution status is startup; S402: whether the replacement advertisement mark is "non-replacement"; S403: fetching the latest time stamp HLS segment information; S404: call replacement The video output module generates a target segment index m3u8 file; S405: remove the channel segment to list the first channel HLS segmentation information; and S406: the execution state is set to pause.

The latest piece of channel HLS segmentation information is retrieved from the channel segmentation queue 2260, and the replacement movie output 2240 is updated to update the HLS segmentation index information set 2241, and the destination segmentation index m3u8 file (excluding the advertisement) is generated. In addition to the first channel HLS segmentation information in the channel segmentation queue 2260, the next instruction is awaited. (2) When the replacement advertisement status is "Replacement" (step S500), referring to FIG. 5, the compensation segment number is first calculated (step S501), the removal flag is set to true, and the call replacement movie output 2240 is removed. The flag removes the first movie segment information and adds an advertisement segment file name information to the HLS segment index information set 22410 and increments the advertisement segment count by 1 and sets COUNT to the compensation segment number minus 1 (step S502) Whether to perform the dynamic ad pre-adjustment of the minimum segmentation time difference mechanism of the insertion advertisement process, to determine whether the three conditions are simultaneously established: 1 the ad segment count is less than the number of ad segments 2 the number of remaining ad segments is less than (3 times the compensation score) The number of segments 3 and COUNT are not equal to zero (step S503). If any of the three conditions is not true, the process goes to step S506 to continue; if the three conditions are simultaneously established, the mechanism for initiating the dynamic pre-adjustment of the minimum segment time difference is inserted. The advertisement processing sets the removal flag to false, and the call replacement movie output module adds an advertisement segmentation information to the HLS segmentation index information set 2241, and generates a destination segmentation index m3u8 file according to the content and COUNT Save ad segment 1 and incrementing a count, the number of seconds to wait for video advertising segment, execution jumps to step S503 to continue (step S504). The call replacement movie output 2240 generates the destination segment index m3u8 file according to the content of the HLS segment index information set 2241 (step S505), determines whether the advertisement replacement is completed, and when the advertisement segment count is smaller than the number of the advertisement segmentation movie (step S506), When the condition is not established, after waiting for the second time of the first segmented movie of the HLS segment index information set 2241, the process proceeds to step S502. Continued execution (step S507); when the condition is satisfied, synchronize the channel segmentation queue 2260 and update the HLS segmentation index information set 2241, and change the replacement advertisement status to "wait for replacement completion", and skip to step S600 to continue execution ( Step S508).

Synchronizing the channel segmentation queue 2260, changing the timestamp of the last piece of information of the channel segmentation queue 2260 to the current timestamp; and correcting the timestamp of the second-to-last information, deleting the queue to only the remaining The last two pieces of information.

(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), and waits for the first stroke of the HLS segmentation index information set 2241. The time seconds of the segment movie and the setting of COUNT to the number of compensation segments minus 1 (step S601), the removal flag is set to true, and the call replacement movie output 2240 removes the first segment of the HLS segmentation index information set 2241. The video information, and the first HLS segmentation information is taken from the channel segmentation queue 2260 and added to the HLS segmentation index information set 2241. When each replacement advertisement state is just switched to "waiting for replacement completion", it is necessary to add EXT- X-DISCONTINUITY TAG), generating a destination segmentation index m3u8 file (step S602), determining whether to perform a dynamic pre-adjustment minimum segmentation time difference mechanism for removing advertisement processing, and querying the replacement movie output 2240 for the first of the HLS segmentation index information set. Whether the pen is advertisement information and whether COUNT is zero. If the condition is met, the removal advertisement process of the mechanism of dynamically pre-adjusting the minimum segmentation time difference is started. If the condition is not established, the process proceeds to S605 (step S603), and execution is performed. The pre-adjustment of the minimum segmentation time difference mechanism for the removal of the advertisement process, the call replacement film output 2240 only moves out of the first segmentation information of the HLS segmentation index information set 2241, generates the target segmentation index m3u8 file, and the COUNT decrements by 1, judging Whether the first information after the removal is an advertisement and COUNT is not zero. If the condition is met, wait for the number of seconds of the information and skip to S603. If the condition is not met, go to S605 to execute (S604), determine whether the first information of the HLS segment index information set 2241 is an advertisement, if it is an advertisement, skip to S601 to continue execution, if not, go to S606 to execute (S605), the replacement advertisement status is changed to "non-replacement" and the pen replacement condition is removed, and the notification execution of the monitoring replacement condition 2220 is awaited (step S606). The replacement movie output 2240 updates the record of the HLS segmentation index information set 2241 according to the replacement advertisement status and the removal flag, and then joins the channel HLS URL (the segmentation movie path is absolute) by the channel segmentation movie in the recorded content, and puts In the HLS segment index information set 2241, the target segment index m3u8 of the image quality is generated. (A) When the replacement advertisement status is "non-replacement", there are two cases: (1) initialization (HLS segmentation index information set 2241 is empty), and the module will take out the first 3 from the channel segmentation queue 2260. The pen information is segmented and stored in the HLS segmentation index information set 2241, and the target master m3u8 file of the channel and the target segment index m3u8 file of the image quality are generated. (2) Update (the HLS segment index information set 2241 has content), the module will first retrieve the latest piece of information from the channel segmentation queue 2260, and the segmentation film path is absoluteized and stored in the HLS segmentation index information set 2241. And remove the first information, segmentation index m3u8 file according to the purpose of generating the image quality. (B) When the replacement advertisement status is "Replacement", the first information of the HLS segmentation index information set 2241 may be selected to be removed or the first information may be taken out from the channel segmentation queue 2260 according to the input parameters. And obtaining the information of the advertisement segmentation movie from the current replacement movie list by using the advertisement segmentation count as the index, and placing the segmentation index of the target segment index m3u8 of the image quality in the HLS segmentation index information set 2241 Add 1 and return the number of seconds of the first segment of the segment index. (C) When the replacement advertisement status is "waiting for replacement completion", the first information of the HLS segmentation index information set 2241 may be removed or the first information may be taken out from the channel segmentation queue 2260 according to the input parameters.

<Example>

Please refer to the flow chart of the linear channel replacement film system of FIG. 2, assuming that the content of the replacement video service and the replacement video information provided by the linear channel replacement video management system 1000 are respectively input to the replacement information database 3000. The data sheet 3100 and the replacement information data sheet 3200.

The contents of the replacement service effective data sheet 3100 are as follows:

1. For a single user to give customized advertisements, the contents of the replacement information table 3200 are as follows:

1. Generate and start a replacement movie module 2200 thread; periodically retrieve the replacement service effective data table 3100 content and use chNo to query whether there is a corresponding replacement movie module 2200 thread, if no replacement film module with chNo is generated Group 2200 thread. In this example, there are two IDs: ID15 and ID16 replace the thread module's thread generation, and only the ID15 replacement service tag is started.

2. Add replacement video information and new replacement conditions: After periodically removing the new replacement information of the replacement information data table 3200,

2-1. First, the value of the adLink is searched through the replacement video information set 2300 to determine whether there is repeated replacement information. If there is no repetition, the replacement video segment index list (adList) is retrieved through the URL of the replacement video recorded by the adLink. The list is analyzed for a duration and the information such as adLink, adList, and adDuration is stored in the replacement movie information set 2300, as follows:

2-2. Retrieving the replacement movie segment index list adID with the adLink ID as the ID, and generating 3 channel replacement video information in the replacement condition set 2250 according to the loading replacement information repeatTimes 3, wherein the second The pen's adStartTime is calculated by the first adTime, adDuration and intervalDuration, 2015-12-1620:00:00+14Sec+300Sec=2015-12-1620:05:14, and so on, the third adStartTime, And the advertisements given to user1 are as follows:

The segmentation index file of each image quality is read by using the channel HLS URL in the replacement service information. When there is a new channel HLS segmentation information, it is converted by the time stamp HLS segmentation information, and the channel segmentation is stored. The notification monitoring replacement condition module in the column performs the replacement condition judgment. Repeat this step unless you wait until you receive a pause in the replacement movie service. The initial value of the replacement ad status is "non-replacement". Assume that the channel segmentation queue 2260 has information, as follows

Assume that one of the image quality segmentation indexes of the channel has new segmentation information, and the content is as follows:

And the HLS segment index information set 2241 and the destination segment index m3u8 file in the replacement movie output 2240, as follows:

3. ID15 thread download channel segment m3u8 2210, through the channel HLS URL to read the channel list of each image quality, and to the ID15 thread channel segment queue 2260 query to determine whether each image quality has a new Segmentation information is generated and there is no duplication,

3-1. After converting to a HLS segmentation information with a time stamp with reference to FIG. 7, update a message to the channel segmentation queue 2260, as follows

3-2. The updated information is taken out, and the monitoring replacement condition module 2220 is notified to perform the replacement condition determination.

4. The monitoring replacement condition module 2220 performs the following procedure according to the content of the replacement advertisement state. When the content is "non-replacement", the latest one-time time-stamped HLS segmentation information is taken out from the channel segmentation 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 "displacement" and the initial value of the advertisement segmentation index is zero. The replacement advertisement processing 2230 is then notified regardless of whether or not the conditions of the advertisement are met.

The replacement advertisement processing 2230 determines to perform different functions according to the content of the replacement advertisement status and the content of the HLS segmentation index information set 2241 generated last time: Referring to FIG. 3, the sTimeStamp value of the updated information obtained is stime4, and the eTimeStamp value is etime4 and The replacement condition set 2250 is the adStartTime alignment.

4-1. Assuming that the replacement condition is not satisfied, the representative adStartTime is not between the pieces of information stime4 and etime4, and the replacement advertisement status is set to "non-replacement" (A) replacement advertisement processing 2230 for "non-replacement" processing, see FIG. The call replacement movie output 2240 generates a destination segment index m3u8 containing the user1 name according to the content of the HLS segmentation index information set 2241; for example: user1index.m3u8), and returns the first segmented movie seconds output by the m3u8. 4.11 seconds (the number of seconds of the fragment is 4 seconds), as follows:

After waiting for 4 seconds, when the download channel segment m3u8 2210 has new segmentation information generated, the channel segmentation column 2260 first data is updated and the HLS segmentation index information set 2241 content is updated:

4-2. Assuming that the replacement condition is satisfied, on behalf of adStartTime, the replacement advertisement status is set to "displacement" between the pieces of information stime4 and etime4, and the advertisement segment count value is set to zero.

(B) The replacement advertisement processing 2230 performs a "placement" process. Referring to FIG. 5, the calculation compensation segment number is 2, the call replacement movie output 2240 is generated, and the destination segment index m3u8 file is generated, and EXT-X is added to the file. The -DISCONTINUITY tag allows the mobile smart terminal device 5000 to normally play the commercial video from the channel program, and the number of seconds to return the first segmented movie is 4.11 seconds (the number of seconds of the segment is 4 seconds), as follows:

In this example, there are 7 ad segmentation videos in "adList". It is judged that the advertisement has not been replaced yet. After waiting for the segment seconds for 4 seconds, please refer to Figure 5. After S502~S504, the dynamic pre-adjustment minimum is activated. After the mechanism of the segmentation time difference, the movie output 2240 inserts two advertisement segment file names into the HLS segment index information set 2241 and generates the destination segment index m3u8 file, and the advertisement segment count is 3, and the remaining The number of ad segmented videos is 4, as follows:

In S506, it is determined whether the advertisement segment count is 3 or less than the number of advertisement segmentation films, and it is found that the advertisement has not been replaced yet. After S502~S504, after the destination segment index m3u8 file is generated, the advertisement segmentation count is 5, and the remaining advertisements are The number of segmented videos is 2, as follows:

After waiting for 2 seconds, it is judged whether the advertisement segment count is 5 or less than the number of advertisement segmentation films 7, and S502~S504 is executed, the advertisement segmentation count is 7, and the remaining advertisement segmentation film number is zero, as follows:

According to S506, it is determined that the advertisement segment count 7 is equal to the number of advertisement segmentation films 7, the synchronization channel segmentation queue 2260, the time stamp of the last piece of information of the channel segmentation queue 2260 is changed to the current time stamp; and the correction countdown The timestamp of the second information is deleted, only the last two pieces of information are left and the HLS segmentation index information set 2241 is updated and the replacement advertisement status is changed to "waiting for replacement completion", and the replacement advertisement processing 2230 is continued to execute. as follows

(C). When the replacement advertisement status is "Waiting for replacement completion", please refer to Figure 6. After waiting for 2 seconds, set COUNT to the number of compensation segments minus 1, and call replacement movie output 2240 to remove the HLS segmentation index information set. The first segment of the 2241 ad2.ts movie is added to the first segment of the HLS segmentation information N-1.ts from the channel segmentation queue 2260 to generate the target segmentation index m3u8 file, as follows:

Determine whether to perform the dynamic pre-adjustment segmentation time difference mechanism to remove the ad processing? Because the first piece of the HLS segmentation index information set is the advertisement information and the COUNT is 1, the judgment is established, the dynamic pre-adjustment minimum segment time difference mechanism is adopted to remove the advertisement processing, and the dynamic pre-adjustment minimum segment time difference mechanism is adopted to remove the advertisement processing. : Move out the HLS segmentation index information set 2241, the first segmentation information ad3.ts, COUNT decrement 1, and generate the target segmentation index m3u8 file, as follows:

The query determines whether the first information of the HLS segment index information set 2241 is an advertisement, and the first information is ad4.ts advertisement information but COUNT is zero, so the dynamic advertisement pre-adjustment minimum segment time difference mechanism is removed from the advertisement processing.

Skip to S605 to query whether the channel replacement movie segment m3u8 does not contain advertisements, because the first pen of the HLS segment index information set is ad4.ts advertising information, and return to S601 for 2 seconds, then set COUNT as compensation segment. Subtract 1 to remove the first segment ad4.ts movie of the HLS segmentation index information set 2241 and add the first HLS segmentation information N.ts from the channel segmentation queue 2260 to generate the destination segmentation index. M3u8 file, as follows,

After the removal of the advertisement processing by the dynamic pre-adjustment minimum segmentation time difference mechanism, the result of the segmentation index m3u8 file is as follows:

After skipping to S605 and dynamically removing the minimum segmentation time difference mechanism to remove the advertisement processing, the result of the target segmentation index m3u8 file is as follows:

Skip to S605 and check if the channel replacement movie segment m3u8 is already Without advertising (S605), the first pen in the HLS segmentation index information set was found to be N-1.ts not advertising information.

The replacement condition of the replacement condition set 2250 is removed, and the replacement advertisement status is changed to "non-replacement", and the jump to the execution monitor replacement condition 2220 begins.

2. For a number of users to give customized advertisements, the contents of the replacement information sheet 3200 are as follows: The contents of the replacement information sheet 3200 are as follows:

As described in (a) the steps a single user gives to a customized advertisement, the different parts are as follows:
