2.4.11 Measurement Functions
All measurements in the MBS are based on analyzing a video stream, within a
programmable window, using specific algorithms. The measurement results are
stored in registers once per field/frame. A special interrupt is generated to indicate
that the measurement is done. Based on the measurement results, software sets the
control parameters for the picture processing units.

Measurement Block Interface
Converts the inputs format (Y, U/V 8bits) into the format needed by the
measurement units (Y, U/V 9bits).
Histogram Measurement
Analyses the Y component of the input data stream. Used for dynamic contrast
improvement (i.e., histogram modification in QVCP).
Noise Estimator
Analyses the Y component. Controls the setting of LSHR pool ressource in
QVCP.
Black Bar Detector
Analyses the Y component. Results are used to expand the picture to the display
size in case of black bars at the top and/or bottom of the picture.
Black Level Measurement
Analyses the Y component. Used for black stretch.
