Notes: When configured in Stripe Refresh buffer mode (only available with H.264
encoding) the bit rate range is limited to 4 Mbps to 10 Mbps in SD, and
8 Mbps to 40 Mbps in HD.
When configured in Stripe Refresh (+ Audio Encode) (only available with
H.264 encoding) the bit rate range is limited as above and the delay is
increased from <100 ms to <150 ms to allow for the audio encode process.
6.7.1.5 Test Patterns
The video pre-processor can generate the test patterns listed in Table 6.4.
Table 6.4 Test Patterns

Notes: On loss of video the VCM can be configured to select freeze frame, test
pattern, or turn off video PID.
If the PID is removed from the output, a Transport Stream analyzer device
will report the removed PID as a ghost PID, because the reference to it is
still transmitted in the Program Map Table of the MPEG Program Specific
Information.
6.7.1.6 Impairment Reduction
The video pre-processor provides a motion adaptive temporal noise reduction
option.
