Automatically reset video decoder when failed frame synchronization

loss is detected

Value Description

0 Never

1 When frame synchronization loss detected

Set Stabilization Bias (0x12)

Adjust the stabilization solution by adding a constant bias in pixel coordinate space to the current

coordinates each frame. This is used to feed forward user controlled camera motion so that

stabilization does not “fight” against camera pan and tilt. Set “auto bias” mode to automatically

prevent the system from stabilizing against constant motion. Some amount of motion lag will still be

experienced in “auto bias” mode.

NEW 2.18 Manual bias offsets can be used in “auto bias” mode. In “auto bias” mode, set column and

row bias to 0 for “auto bias” only. Changes to the column and row bias values will be added to the

“auto bias” solution.

Byte offset Description

2 Packet length = 5

3 Packet type = 0x12

4 -128..127: Per frame column adjustment (bias) in pixels

(signed 8-bit integer)

5 -128..127: Per frame row adjustment (bias) in pixels

(signed 8-bit integer)

6 1 = Enable auto bias (combined auto + manual bias)

0 = Disable auto bias (manual bias only)

Set Metadata Data Values (0x13)

Sets new KLV metadata data values. Latest values are output with h.264 digital video stream.

Metadata is generated in accordance with MISB standards 0102.10, 0601.7, 0603.2, 0604.3, and

0903.3. Selectable KLV elements may be chosen from a superset of the Motion Imagery Sensor

Minimum Metadata Set defined in ST 0902.3. For conversion of values see Table 1 on page 16 of:

http://www.gwg.nga.mil/misb/docs/standards/ST060107.pdf.

Byte offset Description

2 Packet length = 44

3 Packet type = 0x13

4 – 5 Valid data bit mask. Update corresponding data element when bit

value = 1. Unsigned 16 bit integer

6 – 13 UTC time (bit 0) unsigned 64-bit integer
