LIP-SYNC MODE
The Lip-sync parameter selects the PVR 6000 lip-sync mode of operation.
Lip-sync Mode
1 STANDARD LOCK
2{ 2mSec LOCK (ONCE)
3{ 2mSec LOCK (NO DRIFT)
4{ OFF
The available options are:
• STANDARD LOCK – Standard sync of video and audio data within ±40mSec
• 2mSec LOCK (ONCE) – Sync audio to video within ±2 mSec. In this mode,
the PVR 6000 synchronizes the audio to the video only once, monitoring
audio sync to video stops. Only PVR 6040 and PVR 6050 Audio 3 and Audio 4
support this feature.
• 2mSec LOCK (NO DRIFT) – Sync audio to video within ±2 mSec. In this
mode, the PVR 6000 continuously monitors the audio sync to video for
maintaining synchronization within ±2 mSec. Only PVR 6040 and PVR 6050
Audio 3 and Audio 4 support this feature.
• OFF – No Lip-Sync
STC-PCR DELAY
The STC PCR Delay parameter sets the delay between the System Time Clock
(STC) and the PVR 6000 clock. The PVR 6000 clock is recovered from PCR data
to compensate for:
• Delay between STC and PCR
• Correctly processing the Presentation Time Setup (PTS)
• Preventing a buffer underflow
STC-PCR DELAY
040 [mSec]
<000 - 300>
Available delay range is a number from 0 to 300 mSec.
NOTE
In the Web management interface, set the STC PCR Delay by typing the
required delay (in Milliseconds) into the parameter’s free text window.
