3. The method of claim 1 , further comprising:

correcting the non-uniformity in the plurality of frames of the thermal infrared data, wherein each frame of the plurality of frames includes an array of pixels; and

replacing bad pixels detected in the array of pixels for each frame of the plurality of frames of thermal infrared data.

4. The method of claim 3 , wherein the contrast enhancement process comprises AGC.

5. The method of claim 4 further comprising throttling a data rate of the thermal data, wherein the data rate is dynamically adjusted.

6. The method of claim 5 , further comprising adjusting a resolution of the thermal data.

7. The method of claim 1 wherein a portion of the temperature map is transmitted concurrently with one frame in the plurality of frames of the thermal infrared data.

8. The method of claim 7 wherein the thermal data of the scene comprises thermal video.

9. The method of claim 1 wherein transmitting the temperature map and the thermal data in a data channel comprises separately transmitting the temperature map and the thermal data in the data channel.
