4.6.2 Severe Motion Artifacts
Most likely there is a synchronization problem with reversed 3-2 pull-down in 60 Hz-to-24 Hz film-to-digital
conversion in your source. The display file needs correction.
4.6.3 Image Appears Vertically Stretched or ‘Squeezed’ into Center of Screen
Source data converted from film and “pre-squeezed” for the CP2230 display format may require use of an
anamorphic lens (or resizing) to regain full “scope” image width and proper proportions. Verify the Resolution
and Aspect Ratio settings in the
Advanced Setup: Source File Setup
window as well as the Lens Factor in the
Advanced Setup: Screen File Setup
window.
4.6.4 No Image, Just Pink Snow
If you see no image, just pink snow, the enigma has likely been bypassed. Reconnect the enigma by selecting
the
LD Bypass
checkbox in the
Channel Setup: Config 2
window.
4.6.5 No Image, Just Solid Black or Green Display
A black screen error occurs when the Link Decrypter is not processing video content and produces a fixed,
solid image. A black screen will appear when not processing 2D content and a green will appear when not
processing 3D content.
1. Ensure the service doors are closed.
2. Ensure that marriage is established. Check the Marriage light on the main window of the TPC.
NOTE
:
It
takes 45-60 seconds after reset or power-up for the Link Decrypter to verify the marriage with the ICP.
During this time, the LD will not accept any TLS connections or keys from the Cinema Server.
3. The LD must not be in a FIPS error state. There are multiple integrity checks performed by the LD on
startup and operation. A failure of any of these checks will cause the LD to enter the FIPS error state,
during which no cryptographic operation is allowed (No TLS connections, no Cinelink-2 decryption).
NOTE
:
If the LD is in the FIPS error state, you can try resetting or power-cycling the LD (the projector)
to attempt to recover.
4. Ensure the LD logs are not full. If so, the LD will not accept any Cinelink-2 keys until enough log records
have been read by the Security Manager (SM) to allow the LD to create new log records. It is the
responsibility of the Cinema Server to read/clear the LD’s logs.
5. The LD Real Time Clock must be set correctly. If it is not correct, it may reject the client certificate
presented by the server during TLS negotiations.
6. Ensure the LD security cover is intact. These are the metal covers on the LD card itself. Also, ensure the
battery is charged and that the LD keys and certificate are intact.
4.6.6 Colors in the Display are Inaccurate
The color, tint, color space and/or color temperature settings may require adjustment at your input source or in
the
Channel Setup: Config 2
window. Ensure the correct
PCF
,
TCGD
and
Color Space
file for the source
are used.
