Adaptive Bit Rate

CS:

If the client wants to improve the quality of the broadcast on the viewer side, CS can propose to start using an adaptive bit rate (ABR). To proceed with this feature it is important to submit a client request to the Ops-team regarding the activation of the ABR on the clients’ broadcast.
