Is there any flowchart to briefly describe all basic algorithms of the ABR streaming over HLS and DASH? (e.g. the flowchart I attached) Since I cannot find something like this. Thank you for help.

Both Apple HLS and MPEG-DASH ABR delivery is controlled on the player side. A switch happens when network conditions change.

If you type in “flowchart adaptive bitrate streaming” in Google, there are several flowcharts that come up under the images tab and I think you will easily find one for HLS and Dash.

Thank you so much, so the algorithms used in Wowza are similar to the ones over the internet?
