Example Simultaneous Output Capabilities (Single StreamZHD Live ABR)

The following tables provide some examples of the simultaneous outputs that can be created on a single StreamZHD Live ABR encoder with each adaptive streaming technology. Resolutions, frame rates, bit rates and compression parameters can be extensively customized, which may result in a higher or lower number of simultaneous outputs.

Apple iPhone HTTP Streaming

Multiple layers for HTTP streaming to Apple iPhone devices (typically four layers, per Apple’s recommendations) can be easily created while using only a small percentage of a StreamZHD Live ABR system’s processing power. Additional encodes can be performed concurrently while creating multiple iPhone outputs.
