Instruction Manual – HDMI-UTPRO-0808
If a source could support 16 or more sinks downstream from the HDMI UTPro and a 17
th
sink is added
downstream of the HDMI UTPro, the protected content stops transmitting and the HDMI matrix switching
input automatically clears its cache. The input will authenticate each of the downstream sinks again, but when
it reaches the 17
th
sink, the protected content stops transmitting and the cache is cleared. This process will
continue indefinitely until one of the HDMI UTPro’s downstream sinks has been unplugged, bringing the
number back to 16 (the HDMI UTPro’s sink limit).
Four Examples of HDCP Source Sink Support (FIG. 35 through FIG. 38):
The next four figures illustrate system setups in which the source device supports a maximum of 3 sinks downstream of
the first repeater (R1) with varying numbers of repeaters and destinations.
FIG. 35 Example #1 – Source device supports 3 sinks (three destination devices) downstream of R1
FIG. 36 Example #2 – Source device supports 3 sinks (R2 and two destination devices) downstream of R1
FIG. 37 Example #3 – Source device supports 3 sinks (R2, R3, and one destination device) downstream of R1
