C5115-DAT-01H
4.4.2 DVI Capture Window
DE (Display Enable), HSYNC and VSYNC are synthesized internally by examining the active
regions of each line and compensating for possible source timing errors and/or embedded
HSYNC / VSYNC jitter.
There are two ways to define the DVI capture region:
CREF Capture
- In this mode the usual active window parameters must be programmed as with
ADC inputs (see Section 4.3.5.).
DE Capture
- In this mode the active window code embedded in the DVI signal defines the
active window automatically. Only the active width and active length parameters obtained by
performing Input Format Measurement (IFM) need be programmed.
4.4.3 High-Bandwidth Digital Content Protection (HDCP)
Note:
This section applies to the HDCP-enabled chip versions gm5115-H and gm5125-H but not
the standard versions gm5115 and gm5125.
The HDCP system allows authentication of a video receiver by a video transmitter, decryption of
transmitter-encoded video data by the receiver, and periodic renew-ability of authentication
during transmission. The gm5115/25 implements circuitry to allow full support of the HDCP 1.0
protocol for DVI inputs.
For enhanced security, Genesis provides a means of storing and accessing the secret key given to
individual monitor units in an encrypted format.
Further details of the protocol and theory of the system can be found in the
High-bandwidth
Digital Content Protection System
specification (see

The gm5115/25 contains hundreds of test patterns, some of which are shown in Figure 13. Once
programmed, the gm5115/25 test pattern generator can replace a video source (e.g. a PC) during
factory calibration and test. This simplifies the test procedure and eliminates the possibility of
image noise being injected into the system from the source. The foreground and background
colors are programmable. In addition, the gm5115/25 OSD controller can be used to produce
other patterns.
