Receiver ID
A 40-bit value that uniquely identifies the HDCP
Receiver. It has the same format as an HDCP 1.x
KSV i.e. it contains 20 ones and 20 zeroes.
Session Key
A 128-bit random, secret cryptographic key
negotiated between the HDCP Transmitter and
the HDCP Receiver during Session Key exchange
and used during HDCP Content encryption or
decryption.
Upstream Content Control Function
The HDCP Transmitter most upstream in the
HDCP System receives Audiovisual Content to
be protected from the Upstream Content Control
Function. The Upstream Content Control Function
is not part of the HDCP System, and the methods
used, if any, by the Upstream Content Control
Function to determine for itself the HDCP System is
correctly authenticated or permitted to receive the
Audiovisual Content, or to transfer the Audiovisual
Content to the HDCP System, are beyond
the scope of this specification. On a personal
computer platform, an example of an Upstream
Content Control Function may be software
designed to emit Audiovisual Content to a display
or other presentation device that requires HDCP.
Upstream
The term, upstream, is used as an adjective to refer
to being towards the source of the HDCP Content.
For example, when an HDCP Transmitter and an
HDCP Receiver are connected over an HDCP-
protected Interface, the HDCP Transmitter can be
referred to as the upstream HDCP Device in this
connection. For another example, on an HDCP
Repeater, the HDCP- protected Interface Port(s)
which can receive HDCP Content can be referred
to as its upstream HDCP-protected Interface
Port(s). See also, downstream.
