Cobalt Co9992-4ENC-4K-HEVC Software-Defined Broadcast Encoder - Manual (Page 37)

Encoder Mode
The Encoder Mode Tab is used to manage the parameters that are common to all encoder
instances.
Encoder Mode Configuration Tab
The configurable parameters are:

Encoder Mode : The 9992-ENC can be configured either as a 4-channel HD encoder or a
single-channel 4K encoder. Note that 4K operation requires the +4K option (factory
installed in the 9992-ENC-4K-HEVC model). Also note that 4K operation is not
supported for MPEG-2.

Compression Standard : This selects the compression standard. Note that, in
multi-channel mode, all channels will use the same compression standard . The options
are:
o H.265 (HEVC): This selects H.265 (High Efficiency Video Coding)
compression. HEVC operation requires the +HEVC option (factory installed in
the 9992-ENC-4K-HEVC model). When HEVC is selected, the Latency Mode
selection is presented:

Normal Encoding Latency : this mode is optimized for video quality, and
all the HEVC parameters are available for configuration.

Ultra Low Latency : this mode is optimized for low latency (less than one
frame). Notes:
o Many configuration parameters will not be available in this mode.
o Ultra Low Latency operation requires the optional +ULL license.
