UG-707 ADV8005 Hardware Reference Manual
6.13.2. Multiple Sinks and No Upstream Devices
When connecting the ADV8005 as a source to an HDMI input of a repeater, it is necessary to read all BKSVs from downstream devices. These
BKSVs must be checked against a revocation list, which will be provided on the source content.
bksv_count[6:0] will read 0 when the first BKSV interrupt occurs with bksv_flag_int set to 1. After the first BKSV interrupt is cleared, if the sink
connected to the ADV8005 is a repeater, a second BKSV interrupt will occur. The ADV8005 will automatically read up to 13 5-byte BKSVs at a
time and store these in the EDID memory. These BKSVs can be accessed from the EDID Map, as shown in Table 69 . The number of additional
BKSVs available stored in the EDID Map can be obtained from bksv_count[6:0] . If there are more than 13 additional BKSVs to be processed,
the ADV8005 will collect the next up to 13 BKSVs from the sink, then generate another BKSV interrupt with bksv_flag_int set to 1 when the
next set is ready.
