Pre Compression Processor Model VP3000
Pre Compression Processor Model VP3000
Description - PDF Spec Sheet

The Model VP3000 Pre Compression Processor is state of the art professional equipment. It delivers significant picture quality improvements by correcting most common video errors. It can remove dropouts and impulse noise and reduce random interference and noise by up to 9 dBs.

The unit provides independent noise reduction of the luminance and chrominance signals using recursive filtering techniques with motion detection and motion compensation. In addition, the VP3000 provides means to compensate luminance high frequency losses; it permits correction of chrominance level and chrominance phase for proper restoration of color levels and color hue; and it can remove most video dropouts, impulse noise, threshold sparkles and other similar interference.

The VP3000 is ideal for transmission uplinks utilizing digital compression techniques (e.g. MPEG), where random noise can severely affect compression efficiency and any unwanted interference can use up a considerable amount of data. It is highly effective in video postproduction applications as it will improve picture quality from old video tapes and faded films. It can be used as a very high quality NTSC color decoder for format conversion and presentation applications.

The VP3000 uses programmable large gate array chips to perform complex signal processing operations with a high degree of accuracy and reliability. Chip programmability permits custom modifications and future upgrades by simply changing a PROM.
