The ADV7182A features an automatic gain control (AGC)

algorithm to ensure that the optimum luma gain is selected as

the input video varies in brightness.

Adaptive contrast enhancement (ACE) is an algorithm that

automatically varies the contrast level applied across an image to

enhance the picture detail visible. This automatic variation enables

the contrast in the dark areas of an image to be increased without

saturating the bright areas, which is particularly useful in

automotive applications where it can be important to be able

to clearly discern objects in shaded areas.

Downdithering from eight bits to six bits enables ease of design

for standard LCD panels.

The SDP can handle a variety of VBI data services, such as

closed captioning (CCAP), wide screen signaling (WSS), copy

generation management system (CGMS), and teletext data

slicing for world standard teletext (WST). Data is transmitted via

the 8-bit video output port as ancillary data packets (ANC).

The ADV7182A is fully Rovi™ (formerly Macrovision® and now

rebranded as TiVo upon acquisition of the same) compliant;

detection circuitry enables Type I, Type II, and Type III

protection levels to be identified and reported to the user. The

SDP is fully robust to all Rovi signal inputs.
