Bit-
Rate can be adjusted “on

fly”
(without stopping the stream) on
both the HEVC and H.264 channel.
.
To adjust automatically the bit-rate based on available bandwidth on the
network, use Zixi ABR (Adaptive Bitrate) streaming protocol as detailed in
section
. A Zixi compatible decoder such as MGW
Ace Decoder or VITEC Playout Server must be used.
Video Codec Profile
Select the video codec.

For HEVC channel it is recommended to use 10-Bit encoding in any
application for best video quality results. 8-Bit encoding is provided to ensure
compatibility with 8-Bit only decoders.
