使用案例刪除和替換廣告

以下是刪除和替換廣告的使用案例：

標籤範圍

實施 PTTimeRangeCollection 將內容範圍標籤為廣告：

1. 準備 PTTimeRangeCollection。

2. 設定 PTTimeRangeCollection 至 PTTimeRangeCollectionTypeMarkRanges。

   此步驟通知TVSDK必須將自定義範圍視為廣告。

   #define PSDK_TIMESCALE 100000
   
   NSArray *ranges =  @[
     [PTReplacementRange
       replacementRangeWithRange:CMTimeRangeMake(CMTimeMakeWithSeconds
         (0, PSDK_TIMESCALE),CMTimeMakeWithSeconds(60, AD_TIMESCALE))],
     [PTReplacementRange
       replacementRangeWithRange:CMTimeRangeMake(CMTimeMakeWithSeconds
         (120, PSDK_TIMESCALE),CMTimeMakeWithSeconds(60, AD_TIMESCALE))]
   ];
   
   PTTimeRangeCollection *timeRangeCollection =
     [[PTTimeRangeCollection alloc] initWithRanges:ranges
       type:PTTimeRangeCollectionTypeMarkRanges];
   

3. 建立 PTAdMetadata 並設定 PTTimeRangeCollection。

   // Create the PTPlayerItem metadata
   PTMetadata *metadata = [[PTMetadata alloc] init];
   
   // Create the Ad metadata
   PTAuditudeMetadata *adMetadata = [[PTAuditudeMetadata alloc] init];
   adMetadata.timeRangeCollection = timerangeCollection;
   
   //Set Ad metadata
   [metadata setMetadata:adMetadata forKey:PTAdResolvingMetadataKey];
   
   //Create PTMediaPlayerItem
   PTMediaPlayerItem *playerItem = [[[PTMediaPlayerItem alloc] initWithUrl:mediaUrl
                                                                   mediaId:mediaId
                                                                  metadata:metadata];
   

4. 建立播放器並開始播放。

   //Create PTMediaPlayer using the created PTMediaPlayer
   PTMediaPlayer *player = [PTMediaPlayer playerWithMediaPlayerItem:playerItem];
   
   //Add player to the player UIView
   [self.playerView addSubview:(UIView *)player.view];
   
   //Start playback
   [player play];
   

替換範圍

實施 PTTimeRangeCollection 將內容範圍作為廣告刪除：

1. 準備 PTTimeRangeCollection。

2. 設定 PTTimeRangeCollection 至 PTTimeRangeCollectionTypeReplaceRanges。

   此步驟通知TVSDK需要用備用內容（廣告）替換提供的範圍。

   #define PSDK_TIMESCALE 100000
   
   NSArray *ranges =  @[
     [PTReplacementRange replacementRangeWithRange:CMTimeRangeMake(CMTimeMakeWithSeconds
       (0, PSDK_TIMESCALE),CMTimeMakeWithSeconds(60, AD_TIMESCALE))
       replacementDuration:CMTimeMakeWithSeconds(30, AD_TIMESCALE)],
     [PTReplacementRange replacementRangeWithRange:CMTimeRangeMake(CMTimeMakeWithSeconds
       (120, PSDK_TIMESCALE),CMTimeMakeWithSeconds(60, AD_TIMESCALE))
       replacementDuration:CMTimeMakeWithSeconds(30, AD_TIMESCALE)]
                       ];
   
   PTTimeRangeCollection *timeRangeCollection =
     [[PTTimeRangeCollection alloc] initWithRanges:ranges
                                              type:PTTimeRangeCollectionTypeReplaceRanges];
   

   秘訣

   論點 replacementDuration 為可選項。 如果未定義， AdServer 確定廣告分段的持續時間。

3. 建立 PTAdMetadata 並設定 PTTimeRangeCollection。

   //Create the PTPlayerItem metadata
   PTMetadata *metadata = [[PTMetadata alloc] init];
   
   //Create the Ad metadata
   PTAuditudeMetadata *adMetadata = [[PTAuditudeMetadata alloc] init];
   adMetadata.timeRangeCollection = timerangeCollection;
   adMetadata.zoneId = adZoneId;
   adMetadata.domain = adDomain;
   adMetadata.signalingMode = PTAdSignalingModeCustomRanges;
   
   //Set Ad metadata
   [metadata setMetadata:adMetadata forKey:PTAdResolvingMetadataKey];
   
   //Create PTMediaPlayerItem
   PTMediaPlayerItem *playerItem = [[[PTMediaPlayerItem alloc] initWithUrl:mediaUrl
                                                                   mediaId:mediaId
                                                                  metadata:metadata];
   

   秘訣

   儘管 signalingMode 設定為 PTAdSignalingModeCustomRanges，此ad信令模式在設定 PTTimeRangeCollection 類型 PTTimeRangeCollectionTypeReplace。

4. 建立播放器並開始播放。

   //Create PTMediaPlayer using the created PTMediaPlayer
   PTMediaPlayer *player = [PTMediaPlayer playerWithMediaPlayerItem:playerItem];
   
   //Add player to the player UIView
   [self.playerView addSubview:(UIView *)player.view];
   
   //Start playback
   [player play];
   

刪除範圍

實施 PTTimeRangeCollection 將內容範圍作為廣告刪除：

1. 準備 PTTimeRangeCollection。

2. 設定 PTTimeRangeCollection 至 PTTimeRangeCollectionTypeDeleteRanges，它通知TVSDK需要刪除提供的範圍。

   #define PSDK_TIMESCALE 100000
   
   NSArray *ranges =  @[
     [PTReplacementRange replacementRangeWithRange:CMTimeRangeMake(CMTimeMakeWithSeconds
       (0, PSDK_TIMESCALE),CMTimeMakeWithSeconds(60, AD_TIMESCALE))],
     [PTReplacementRange replacementRangeWithRange:CMTimeRangeMake(CMTimeMakeWithSeconds
       (120, PSDK_TIMESCALE),CMTimeMakeWithSeconds(60, AD_TIMESCALE))]
   ];
   
   PTTimeRangeCollection *timeRangeCollection =
     [[PTTimeRangeCollection alloc] initWithRanges:ranges
                                              type:PTTimeRangeCollectionTypeDeleteRanges];
   

3. 建立 PTAdMetadata 並設定 PTTimeRangeCollection。

   //Create the PTPlayerItem metadata
   PTMetadata *metadata = [[PTMetadata alloc] init];
   
   //Create the Ad metadata
   PTAuditudeMetadata *adMetadata = [[PTAuditudeMetadata alloc] init];
   adMetadata.timeRangeCollection = timerangeCollection;
   adMetadata.zoneId = adZoneId;
   adMetadata.domain = adDomain;
   adMetadata.signalingMode = PTAdSignalingModeServerMap;
   
   //Set Ad metadata
   [metadata setMetadata:adMetadata forKey:PTAdResolvingMetadataKey];
   
   //Create PTMediaPlayerItem
   PTMediaPlayerItem *playerItem = [[[PTMediaPlayerItem alloc] initWithUrl:mediaUrl
                                                                   mediaId:mediaId
                                                                  metadata:metadata];
   

   秘訣

   廣告插入在根據 PTAdMetadata 和當前 PTAdSignalingMode。

4. 建立播放器並開始播放。

   //Create PTMediaPlayer using the created PTMediaPlayer
   PTMediaPlayer *player = [PTMediaPlayer playerWithMediaPlayerItem:playerItem];
   
   //Add player to the player UIView
   [self.playerView addSubview:(UIView *)player.view];
   
   //Start playback
   [player play];
