Stills Detection Control
Setting this to other than Off will override the in-built intelligent stills detection. This
saves bit rate but has undesired video quality effects on complex stills.
Film Mode
The pre-processor identifies 3:2 pull-down sequences. Based on this information the
encoding engine identifies the appropriate fields as repeated. Film Mode can only be
sued for SD inputs with a frame rate of 29.97 Hz.
B.3.6.5 Operating Times
Boot Time
The module has a complete boot time (from release of reset to generating valid
Transport Streams) of typically 2 minutes. This time is dependent on a valid
configuration being available when the module requires it to complete its boot
process.
Configuration/Mode Changes
Configuration
The VCM, when in the same operating mode, changes configuration within two
seconds plus the video delay. This means that the visible glitch period is two
seconds. This includes most coding parameter changes including GOP size,
resolution changes and filter settings.
Mode
For mode changes (profile changes, frame rate, VBR modes and delay modes), the
configuration is complete within ten seconds (to include the time to reset the
buffer). The change time is defined as the time from the configuration change being
received on the module to the module outputting a changed bit stream.
Audio/VBI
The module changes the configuration of the audio and VBI data within 1 second
plus the video delay. On the audio, the audible glitch period is 1 second plus the
video delay as the buffer will be cleared. The change time is defined as the time
from the configuration change being received on the module to the module
outputting a changed bit stream.
B.3.6.6 Test Pattern
Test patterns are supported within this release.
B.3.7 Audio
The AVP 4000 supports the following modes of operation for audio:
