Challenge 5: Ready for some Ads?
Previous Challenge Next Challenge
Introduction
In this challenge, we’ll be using TX Darwin to insert ad markers in our stream that we will use later in our pipeline to insert the ads we created in the first challenge.
Techex’s TX Darwin is a software-based platform designed for processing, transporting, and monitoring live video workflows in the media industry.
We will be using Darwin specifically for ad insertion into our stream. This means we will be taking the SRT stream that is now coming out of VizRT Vectar and inserting SCTE-35 markers into it.
SCTE-35 markers, colloquially known as “scuddy markers”, are a digital signal embedded within a video stream that carries instructions for downstream pipeline elements. They are most commonly used to signal the exact start and end points for inserting ads.
Tools Used
- Techex TX Darwin
Description
TX Darwin is a web app running in our environment access through a webpage. Your coach will provide log in details.
Configure SRT Ingestion
- Create a new input and configure it to be an SRT source.
- Paste the SRT output URL from VizRT Vectar into the ingest configuration. The program feed from Vectar should now be flowing into Darwin.
Configure a SCTE-35 Marker
- The Darwin interface has a feature for live stream manipulation. Look for the button labelled “Insert SCTE-35 Marker”.
- Pressing this button injects the SCTE-35 marker into the SRT stream in real time, signaling that an ad should be inserted.
- This doesn’t change the video content itself but adds metadata that downstream pipeline elements will use.
Configure SRT Output
- Create a new SRT output for the stream that now contains the SCTE-35 marker.
Note
Write down this new SRT output URL for the next challenge.
Success Criteria
- You’ve consumed the SRT source from the VizRT Vectar program output
- A SCTE-35 marker has been manually inserted into the stream
- You’ve configured an SRT output for the next challenges
