Yes. The way it works now is:
- Play video until ad timestamp
- Pause video and fetch ad from ad server
- Play ad
- Resume video
But presumably with the new system, your computer will just receive a continuous bitstream with ads embedded in them. What was previously happening on your machine through HTML or JavaScript and was detectable by ad blockers, will now happen on YouTube servers beholind the scenes.
