Encoding specification
The encoding specification applies to SSAI Live and VoD content, unless there are specific notifications to be considered.
Encoding specification
We recommend the following bitrate ladder for Live and Video-On-Demand. This will ensure a smooth streaming experience and optimal quality on all devices and connection types.
