> That's because every video feed usually needs to be realtime, low-latency transcoded to match the receivers bandwidth requirements.
Scalable video (and audio) never seemed to have taken off:
> SVC standardizes the encoding of a high-quality video bitstream that also contains one or more subset bitstreams. A subset video bitstream is derived by dropping packets from the larger video to reduce the bandwidth required for the subset bitstream. The subset bitstream can represent a lower spatial resolution (smaller screen), lower temporal resolution (lower frame rate), or lower quality video signal.
