Now – let’s look at a bandwidth calculator for some common timings and familiar content:
All calculations above are RGB or YCbCr 4:4:4 8-bit (24-bit column above – 8 bit per RGB pixel =
24-Bit). What you can see is that at 4K 60 Hz 4096x2160 @ 60 frames per second (FPS) and 8-bit
we max out at 17.5 GBP/sec which is the top of the HDMI 2.0 specification (18 GBP/sec) - this is
the uncompressed figure. In the example above we also show data rates using MPEG
compression – this is what allows us to have high bandwidth content delivered to us through the
various media in our homes and businesses without visual artifacts.
That being said – certain timings, bit depths and color space combinations cannot be selected as
they exceed the maximum bandwidth requirement for HDMI 2.0 of 18 GBP/sec. The SIX-G will
not allow you to select an invalid combination of values.
4.
HDCP Setting
– This screen allows you to select (turn on) HDCP 1.4, HDCP 2.2 or NO HDCP.
This feature is useful for troubleshooting. HDCP settings. The ability to choose HDCP 1.4,
HDCP 2.2 and HDCP OFF. Even though you have an HDCP 2.2 compatible source,
sometimes displays and HDMI distribution equipment claim implementation but only
provide actual support on one or some of the inputs or even without supporting
18GBP/sec (2160P60 4:4:4 8-bit). The only way to verify what is happening is to use the
SIX-G. EXAMPLE: We have discovered some displays will accept HDCP 2.2 but only in
4K30, 4K60 is only accepted in HDCP OFF for PC signals.
5.
HDMI/DVI Setting
– Select DVI or HDMI or AUTO. AUTO reads the EDID for this setting.
6.
Audio Sampling
– Allows audio sampling rates between 32K and 192K. AUTO may also be
selected in which case the sampling rate listed in the EDID preferred rate will be used.
7.
Audio Sampling Size –
16-bit, 20-bit and 24-bit selections are available as is AUTO (EDID).
8.
Audio Source:
a. INT – Internal 1K Test Tone – for confidence testing – does the audio pass through
the distribution system? (HDMI, HDBaseT HDIP, etc.) With 32 combinations of
speaker configuration you can test connectivity for every speaker in the system.
