# Apple HLS output
<a name="apple-hls-output"></a>

Apple HLS output supports both passthrough of the SCTE-35 messages and manifest decoration. In fact, with HLS outputs, passthrough and manifest decoration are either both enabled or both disabled. Therefore, workable options are: 


| SCTE-35 passthrough | Insertion of SCTE-35 messages | Manifest decoration | Blanking and blackout | Effect | 
| --- | --- | --- | --- | --- | 
| Enabled | Yes or No | Enabled | Yes or No | Turns on passthrough of SCTE-35 messages and manifest decoration. In this case, you could also insert more SCTE-35 message if desired. You could also implement blanking and blackout. | 
| Disabled | No | Disabled | No | Turns off passthrough in order to remove SCTE-35 messages from the video stream. Turns off manifest decoration. Do not insert extra messages: they simply get stripped from the output. Do not implement blanking or blackout. <br />Choose this option only if, in a downstream system, you do not want to replace video that was originally marked by cues.  |
