背景技术Background technique
目前常见的线性频道插广告方法是采取让每位使用者都给予相同广告观赏的做法。如果想要达到每位使用者可观赏到定制化、针对性的广告影片服务，通过现行直播频道服务采用HLS(HTTP Live Streaming，超文本传输协议流媒体直播)串流，单一个线性频道需要同时提供n个profile的影音档案、且1个profile有3个ts，如有m个使用者，就需要3乘以n乘以m倍的储存空间来存放m个使用者的HLS单一个线性频道节目内容，再加上k个线性频道，那就需要3乘以n乘以m乘以k倍的庞大储存空间来存放k个线性频道的HLS节目内容，这种做法需要持续分析直播频道节目的内容，寻找是否有数字提示音标记，然后抽离原GOP(Group of Picture，画面群)信息置换成广告I-GOP，产生新的直播频道节目档，相当耗费运算资源，且无法在加密频道节目进行插广告。因此无法针对每位使用者给予定制化广告和无法在加密频道节目中插入广告的缺点。The current common method of inserting advertisements in linear channels is to allow each user to watch the same advertisement. If you want to achieve customized and targeted advertising video services for each user, through the current live channel service using HLS (HTTP Live Streaming, hypertext transfer protocol streaming media live broadcast) streaming, a single linear channel needs to be streamed at the same time Provide n profile audio and video files, and 1 profile has 3 ts, if there are m users, it needs 3 times n times m times of storage space to store the HLS single linear channel program of m users content, plus k linear channels, then a huge storage space of 3 times n times m times k times is required to store the HLS program content of k linear channels. This method requires continuous analysis of the content of live channel programs , to find out whether there is a digital prompt tone mark, and then extract the original GOP (Group of Picture) information and replace it with an advertising I-GOP to generate a new live channel program file, which consumes a lot of computing resources and cannot be performed on encrypted channel programs. Insert ads. Therefore, it is impossible to provide customized advertisements for each user and to insert advertisements in encrypted channel programs.

When the replacement advertisement status is just switched to "waiting for replacement completion", you need to add EXT- X-DISCONTINUITY TAG), generate the destination segmentation index m3u8 file (step S602), determine whether to perform the removal advertisement processing of the dynamic pre-adjustment minimum segmentation time difference mechanism, and query the first one of the HLS segmentation index information set to the replacement movie output 2240 Whether the pen is advertisement information and whether COUNT is zero, if the condition is established, start the removal advertisement processing of the mechanism of dynamic pre-adjustment minimum segment time difference, if the condition is not established, jump to S605 execution (step S603), execute the dynamic pre-adjustment minimum score Advertisement removal process based on time difference mechanism, call replacement movie output 2240 to remove only the first segment information of HLS segment index information set 2241, generate destination segment index m3u8 file, COUNT decrements by 1, and judge the first segment information after removal Whether a piece of information is an advertisement and COUNT is not zero, if the condition is established, wait for the number of seconds for the information, skip to S603 to continue execution, if the condition is not established, skip to S605 to execute (S604), and judge the HLS segment index information set 2241 Whether the first piece of information is an advertisement, if it is an advertisement, skip to S601 to continue execution, if it is not an advertisement, skip to S606 to execute (S605), change the replacement advertisement status to "non-replacement" and remove the replacement condition, and wait for monitoring Notification of the replacement condition 2220 is performed (step S606). The replacement movie output 2240 will update the record of the HLS segment index information set 2241 according to the status of the replacement advertisement and remove the mark, and then add the channel HLS URL before the channel segment video in the recorded content (the path of the segment video is absolute), and put into the HLS segment index information set 2241, and then generate the target segment index m3u8 of the image quality. (A) When the replacement advertisement status is "non-replacement", there are two situations: (1) initialization (the HLS segment index information set 2241 is empty), this module will take out the first 3 pieces of information from the channel segment queue 2260 , the segmented video path is absolutized and stored in the HLS segment index information set 2241, and the target master m3u8 file 2410 of the channel and the target segment index m3u8 file 2420 of the image quality are generated. (2) update (the HLS segment index information set 2241 has content), this module will first take out the latest information from the channel segment queue 2260, and store the segmented movie path into the HLS segment index information set 2241 and Remove the first piece of information, and index m3u8 files according to the purpose of generating the image quality. (B) When the replacement advertisement status is "replacement", according to the input parameters, you can choose to remove the first piece of information from the HLS segment index information set 2241 or add the first piece of information from the channel segment queue 2260. And use the advertisement segment count as index to obtain the advertisement segment movie information from the current replacement movie list, put it into the HLS segment index information set 2241 to generate the target segment index m3u8 file of the image quality, and count the advertisement segment count value Increment by 1, and return the first segment video seconds of the segment index. (C) When the replacement advertisement status is "Waiting for replacement", according to the input parameters, you can choose to remove the first information of the HLS segment index information set 2241 or add the first information from the channel segment queue 2260, etc.
