© Harmonic Inc. Manual p/n 101543/Ver 1.0 13-7 ProView 2900 Series/SW Version 1.94
13.4. Embedded Mode
This feature will be supported in the future software releases.
13.5. Automatic CAM Reset
Automatic CAM Reset mechanism handles scenarios where the CAM ceases to function
correctly, resulting in no decryption of services and therefore video stop or freezing. Although
frozen, the video output remains a valid signal.
The ProView 2900 detects CAM errors by performing a video lock test that recognizes faulty
video output signals which last longer then the configurable threshold time.
When an error is detected, the ProView 2900 automatically resets the CAM. Reset time may
take 10 to 20 seconds.
The CAM Timeout can be configured through CLI. To configure the CAM Timeout through the
CLI:
1. Go to config/video/general/
2. Set decoding timeout by using the following command:
<port(1/2)> < timeout (seconds), or 0 = disable>
The default CAM Timeout is 10 seconds.
To disable the Automatic CAM reset mechanism set the timeout value to 0.
NOTE
Harmonic recommends setting the CAM Timeout value to five seconds or higher.
