The ADV611/ADV612 are real-time compression integrated
circuits designed for remote video surveillance or closed circuit
television (CCTV) applications. The most important feature of
these two devices is the “Quality Box.” With this feature the
user can define a box of any size and location within each field
of video that will be compressed at full contrast while the re-
mainder outside the box, or background of the image, is com-
pressed at a lower level of contrast. The background contrast
level is controlled by the user. The lower the contrast level, the
more the image will be compressed. The objective in a given

application is to adjust the background contrast to a level that
ensures both a recognizable and useful background as well as
the highest possible compression. Figure 3 shows how this qual-
ity box appears in final video.
The ADV611/ADV612 is housed in a plastic LQFP package
suitable for cost-sensitive commercial applications.
