Note: The packet type values and corresponding packets should not be programmed in the packet type values registers. These packets are
always processed internally and cannot be stored in the packet/InfoFrame registers in the InfoFrame map:
•
0x01: audio clock regeneration packet
•
0x02: audio sample packet
•
0x03: general control packet
•
0x07: DSD audio sample packet
•
0x08: DST audio packet
•
0x09: HBR audio stream packet
REPEATER SUPPORT
The ADV7611 incorporates an EDID/repeater controller that provides all the features required for a receiver front end of a fully
HDCP 1.4 compliant repeater system. The ADV7611 has a RAM that can store up to 127 KSVs, which allows it to handle up to
127 downstream devices in repeater mode (refer to Table 23).
The ADV7611 features a set of HDCP registers, defined in the HDCP specifications, which are accessible through the DDC bus (refer to
the DDC Ports section) of the selected port. A subset of the HDCP registers (defined in the following subsections) are also available in the
Repeater Map and are accessible through the main I
Repeater Routines Performed by the EDID/Repeater Controller
Power-Up
A power-on reset circuitry on the DVDD supply is used to reset the EDID/repeater controller when the ADV7611 is powered up. When
the EDID/repeater controller reboots after reset, it resets all the KSV registers listed in Table 23 to 0x00.
AKSV Update
The EDID/repeater controller resets automatically the BCAPS [5] bit to 0 when an HDCP transmitter writes its AKSV into the ADV7611
HDCP registers through the DDC bus of the HDMI port.
Note: Writing a value in the AKSV[39:32] triggers an AKSV update and AKSV_UPDATE_ST interrupt if AKSV_UPDATE_MB1 or
AKSV_UPDATE_MB2 has been set to 1 This triggers the EDID/repeater controller to reset the BCAPS [5] bit back to 0.
KSV List Ready
The KSV_LIST_READY bit is set by an external controller driving the ADV7611. This notifies the ADV7611 on-chip EDID/repeater
controller that the KSV list registers have been updated with the KSV's of the attached and active downstream HDCP devices.
