MGW Ace Encoder HEVC Encoding and Streaming Appliance
User Manual, Version 2.1 33
Enter the Total Bit-Rate value in Mbps for CBR mode.
Total Bit-Rate and Max in MBps must be filled for Capped VBR.
Refer to Rate Control above for information about each mode.
The Total Bit-Rate value includes the Video / Audio / KLV metadata and
streaming protocol bitrate. It is possible to review the bitrate allocation
using the information button next to the Total Bit-rate value:
Bit-Rate can be adjusted “on-the-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 Error Correction Settings. A Zixi compatible decoder such as MGW
Ace Decoder or VITEC Playout Server must be used.
Select the video codec.
• For channel 1 select any of the HEVC/ H.265 available profiles.
• For channel 2 select any of the H.264 available profiles.
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.
Select this box to ensure optimized HEVC encoding latency. To get best
glass to glass latency, it is recommended to use VITEC decoder: MGW
Ace Decoder, MGW D265, or EZTV.
Low latency mode is not available when B frames are used (not available
in Broadcast Profile).
