Preliminary
Video Signal Noise Reduction and Rate Conversion IC with a Built-in 3.9 Mbit Field Memory
1/14
GENERAL DESCRIPTION
The ML87V2103 comprises a 3.9 Mbit field memory and logic circuits for signal processing and memory control.
The device can reduce field-recursive noise and double the conversion speed.
There is an automatic noise reduction mode that detects the noise level in the input video data to set the optimum
noise reduction.
There are two ways to double the conversion speed: progressive conversion that doubles the number of lines by
doubling the horizontal direction frequency and flicker-free conversion that doubles both the vertical and
horizontal direction frequencies.
