Hi

I need to listen for inject scte-35 signal to hls in wowza media server.

How can we do with wowza ?

Thank you.

it is usually your web encoder which requires the SCTE-35/104 signal. In context of a HLS stream the SCTE-35/104 signal tells the encoder to slice the current segment and to inserted the ad break in form of a CUE-OUT marker. Important here is to have ad break duration available. The duration also determines when to set the CUE-In marker. The final output which would be pushed to your CDN would look similar to this one:

#EXTINF:10, [http://media.example.com/fileSequence7796.ts](http://media.example.com/fileSequence7796.ts)

#EXTINF:6, [http://media.example.com/fileSequence7797.ts](http://media.example.com/fileSequence7797.ts)

**#EXT-X-CUE-OUT:DURATION=30**

#EXTINF:4, [http://media.example.com/fileSequence7798.ts](http://media.example.com/fileSequence7798.ts)

#EXTINF:10, [http://media.example.com/fileSequence7799.ts](http://media.example.com/fileSequence7799.ts)

#EXTINF:10, [http://media.example.com/fileSequence7800.ts](http://media.example.com/fileSequence7800.ts)

#EXTINF:6, [http://media.example.com/fileSequence7801.ts](http://media.example.com/fileSequence7801.ts)

**#EXT-X-CUE-IN**

#EXTINF:4, [http://media.example.com/fileSequence7802.ts](http://media.example.com/fileSequence7802.ts)

#EXTINF:10, [http://media.example.com/fileSequence7803.ts](http://media.example.com/fileSequence7803.ts)

we can additional hardware in order to send the SCTE-35 signal to their web encoder or wowza streamin engine.

Hello,

We have sample code in [the following article](https://www.wowza.com/docs/how-to-monitor-mpeg-ts-ingestion-to-process-additional-data-streams-scte-35-klv-etc) to to monitor MPEG-TS ingestion to process additional data streams (SCTE-35, KLV, etc.) with Wowza Streaming Engine 4.5.0 and above.

The code examples in this article show how to add an MPEG-TS ingestion listener API and PID monitor API to your Wowza Streaming Engine™ media server to extract additional stream data and implement a built-in monitor for SCTE-35 markers and KLV data. Listening to other types of MPEG-TS data is also possible using this API.

Regards,

Andy E.

Do we have any real TV channel that includes SCTE 35 signals?

I have an ATSC receiver and I need to play around with the ad insertion feature.
