(SDR8/SDR10/HDR10)
With the introduction of rmware versions 4.00 (and above), ALIF4000 models now
support video signals with color formats that use 10-bpc (bits per color) as well as the
standard 8-bpc. The supported dynamic ranges are:
• SDR8 - Uses 8-bpc (24-bits in total per pixel), as supported across the ALIF range.
• SDR10 - Uses 10-bpc (30-bits total) in order to dene a wider color gamut.
• HDR10 - Uses 10-bpc to dene a wider color gamut and also benets from support
for ST2084 dynamic range mastering and BT.2020 colorimetry.
All ALIF devices use the AFZ24 codec to support SDR8 signals; ALIF4000 devices (with
rmware v4.xx) also use the newer AFZ30 to support SDR10 and HDR10 modes.
The ability to successfully deliver full SDR10 or HDR10 video signals from a host PC to
any particular remote video display relies upon a series of factors:
• The host PC must produce video signals with SDR10 or HDR10 content.
• The ALIF4000 TX must have rmware v4.00 or greater.
• The receiving ALIF4000 RX units must have rmware v4.00 or greater.
• The video display(s) connected to a receiver must support SDR10 or HDR10.
Where possible, you are recommended to upgrade all ALIF4000 devices to 4.xx
rmware. Where a mix of ALIF4000 and non-ALIF4000 receivers exist, an ALIF4000 TX
will respond in manner discussed on the right to negotiate access.

If a mixture of new and legacy devices is unavoidable and it is vital that no legacy
receiver is ever locked out from a particular ALIF4000 TX, then set the ALIF4000 TX to
use a maximum of 8-bpc (regardless of the input signal):

Max Bits per Colour is set
to ‘8’ on the ALIF4000 TX.
This means that regardless
of the signal type received
from the host (SDR8,
SDR10 or HDR10), the TX
will only send out SDR8.
Consequently, all types of
ALIF RX units are fully
supported, albeit at the
lower dynamic range and
color depth (see lower left).
Max Bits per Colour is set
to ‘10’ on the ALIF4000 TX.
However, the rst RX to
connect with the TX is a
non-ALIF4000 type, which
means that the TX scales
back the video output
to SDR8 for this and all
subsequent RX units.
The ALIF4000 TX has
been set to either SDR10
or HDR10. The rst to
connect with the TX
is an ALIF4000 RX and
subsequently receives
SDR10/HDR10 output.
The next to join is a
non-ALIF4000 RX and is
rejected from connecting. It
will continue to attempt a
connection.
Mixingdevices
Care should be taken when using a mixture of ALIF4000 (v4.00 and greater) and non-
ALIF4000 devices. It is not possible for an ALIF 4000 TX to deliver SDR10/HDR10
to multiple RX units if one or more of them are only able to process SDR8. When a
mixture of RX devices make connection, the TX will employ the following methods to
negotiate access - on a rst-come, rst-served basis:
TXconguredtouseonly8-bpc
Non-ALIF4000RXconnectsrst
ALIF4000RXconnectsrst
After either of the last two scenarios have occurred; once all RX units have disconnected,
the ALIF4000 TX will revert to SDR8, SDR10 or HDR10 (as determined by the host
signal and the ALIF4000 TX settings) and be ready to respond accordingly to connecting
RX units.
