IN1608 xi Scaling Presentation Switcher • Internal Web Pages 93
Aspect ratio
From the Aspect Ratio drop-down menu (see figure 55,
3
, on the previous page), select
Fill or Follow.
• Fill — Scales the input signal to fill the entire video output.
• Follow — Follows the signal aspect ratio, with respect to the current output resolution
setting. Black letter box or pillar box bars may be applied for aspect ratio compensation.
Auto-Image
Select the Auto-Image checkbox (
4
) of the desired input to enable an automatic
Auto-Image to an input. When enabled, Auto-Image is applied whenever there is a change
in the input sync. Auto-Image attempts to size and center the input signal based on the
aspect ratio setting.
By default, the Auto-Image threshold is 25% brightness. Analog video signals greater
than the threshold are considered active video. To change the threshold value, use SIS
commands (see Auto-Image threshold value on page 58).
Auto Memory
Select the Auto Memory checkbox (
5
) of the desired input to enable the Auto Memory (see
the Auto Memory and Auto-Image Interaction table on page 40 for a summary of the
interaction between Auto Memory and Auto-Image). Auto Memory recalls input and image
settings for signals that have previously been applied. When Auto Memory is disabled, the
scaler treats every newly applied input as a new source.
HDCP Authorized
Select the HDCP Authorized checkbox (
6
) to enable or disable the HDCP Authorized
feature (inputs 3 through 8). This feature determines if a digital input reports as an HDCP
authorized sink to a source.
NOTE: This option is not available for analog inputs 1 and 2.
For source devices that require encryption, enable HDCP Authorized. If HDCP Authorized
is disabled for sources that require encryption (for example, a Blu-ray player), the output is
muted or a warning message is displayed.
Some source devices may encrypt their output even if the source material does not require
HDCP encryption, preventing content from being displayed on a non-HDCP compliant
display. Disable HDCP Authorized to allow the output of the scaler to remain unencrypted.
Film Detect
Select the Film Detect checkbox (
7
) of the desired input to enable automatic 3:2 and 2:2
film pulldown detection for NTSC, PAL, SECAM, and 1080i input signals.
