GENERAL DESCRIPTION

The integrated 16 : 9 compressor is an IC which compresses the active part of a video line by a factor of 4⁄3 from, for example, 52 µs to 39 µs. This is necessary to display 4:3 video software on a 16 : 9 tube in the correct proportion. The capacitively coupled video inputs are Y, (B−Y) and (R−Y).

FEATURES

• Fixed horizontal compression by a factor of 4⁄3 for most video standards

• Three fixed screen positions (left, centre and right)

• 5 MHz bandwidth

• Bypass function

• Inputs for luminance and chrominance of side panels

• Standard video inputs and outputs (Y, (B−Y) and (R−Y))

• Horizontal and vertical sync signals are not processed

• Pre filters and post filters on chip.
