目前常見的線性頻道插廣告方法是採取讓每位使用者都給予相同廣告觀賞的做法。如果想要達到每位使用者可觀賞到客製化、針對性的廣告影片服務,以現行直播頻道服務採用HLS串流,單一個線性頻道需要同時提供n個profile的影音檔案且1個profile有3個ts,如有m個使用者,就需要3乘以n乘以m倍的儲存空間來存放m個使用者的HLS單一個線性頻道節目內容,再加上k個線性頻道,那就需要3乘以n乘以m乘以k倍的龐大儲存空間來存放k個線性頻道的HLS節目內容,這種做法需要持續分析直播頻道節目的內容,尋找是否有Digital Cue Tone標記,然後抽離原GOP資訊置換成廣告I-GOP,產生新的直播頻道節目檔,相當耗費運算資源,且無法在加密頻道節目進行插廣告。因此無法針對每位使用者給予客製化廣告和無法在加密頻道節目中插入廣告的缺點。 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 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).

(3)當置換廣告狀態為"等待置換完成"時,請參閱圖6,先判斷置換廣告標記是否為"等待置換完成"(步驟S600),等待HLS分段索引資訊集2241之第一筆分段影片的時間秒數以及將COUNT設為補償分段數減1(步驟S601),將移除標記設為true,呼叫置換影片輸出2240移除HLS分段索引資訊集2241之第一筆分段影片資訊,並從頻道分段佇列2260取出第一筆的HLS分段資訊加入HLS分段索引資訊集2241中,在每次置換廣告狀態剛切換到"等待置換完成"時,需加入EXT-X-DISCONTINUITY TAG),產生目地分段索引m3u8檔(步驟S602),判斷是否執行動態預先調節最小分段時間差機制之移除廣告處理,向置換影片輸出2240查詢HLS分段索引資訊集的第一筆是否為廣告資訊以及COUNT是否為零,如果條件成立,啟動動態預先調節最小分段時間差的機制之移除廣告處理,如果條件不成立,跳到S605執行(步驟S603),執行動態預先調節最小分段時間差的機制之移除廣告處理,呼叫置換影片輸出2240僅移出HLS分段索引資訊集2241之第一筆分段資訊,產生目地分段索引m3u8檔,COUNT遞減1,判斷移除後的第一筆資訊是否為廣告且COUNT不是零,如果條件成立,等待該資訊的時間秒數,跳到S603 繼續執行,如果條件不成立,跳到S605執行(S604),判斷HLS分段索引資訊集2241之第一筆資訊是否為廣告,如果是廣告,跳到S601繼續執行,如果不是廣告,跳到S606執行(S605),將置換廣告狀態改為"非置換"和移除該筆置換條件,等待監控置換條件2220的通知執行(步驟S606)。置換影片輸出2240會依置換廣告狀態及移除標記來更新HLS分段索引資訊集2241的記錄,再由記錄內容中的頻道分段影片前加入頻道HLS網址(分段影片路徑絕對化),放入HLS分段索引資訊集2241中,再產生該畫質的目的分段索引m3u8。(A)當置換廣告狀態為"非置換"時,有兩種情形:(1)初始化(HLS分段索引資訊集2241是空的),該模組將從頻道分段佇列2260取出前3筆資訊,分段影片路徑絕對化後儲存到HLS分段索引資訊集2241,並產生該頻道的目的master m3u8檔及該畫質之目的分段索引m3u8檔。(2)更新(HLS分段索引資訊集2241有內容),該模組會先從頻道分段佇列2260取出最新的一筆資訊,分段影片路徑絕對化後儲存到HLS分段索引資訊集2241及移除第一筆資訊,依產生該畫質之目的分段索引m3u8檔。(B)當置換廣告狀態為"置換"時,依輸入參數可選擇移除HLS分段索引資訊集2241的第一筆資訊或加入從頻道分段佇列2260取出第一筆資訊。並以廣告分段計數為index從current置換影片清單取得廣告分段影片的資訊,放入HLS分段索引資訊集2241中產生該畫質之目的分段索引m3u8檔後,將廣告分段計數值遞加1,並回傳該分段索引第一筆分段影片秒數。(C)當置換廣告狀態為"等待置換完成"時,依輸入參數可選擇移除HLS分段索引資訊集2241的第一筆資訊或加入從頻道分段佇列2260取出第一筆資訊等。 (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.
