LZX Industries - analogue video synthesizer modules and devices http://www.lzxindustries.net Modular analogue video synthesizers and voltage controlled video effects cont Wed, 13 Mar 2013 16:21:23 +0000 en-US hourly 1 http://wordpress.org/?v=3.4.1 Video Divisions http://www.lzxindustries.net/?post_type=module&p=1174 http://www.lzxindustries.net/?post_type=module&p=1174#comments Mon, 29 Oct 2012 15:33:10 +0000 Liz Larsen http://www.lzxindustries.net/?post_type=module&p=1174 Video Divisions is a high speed digital logic processing module with several complex modes for generating horizontal and vertical bars, and dividing other signals. It is capable of processing signals throughout the video bandwidth. Each of the two inputs includes a high speed comparator which converts any input signal into key logic around a threshold of 0.5 Volts. As with all modules in the LZX Visionary line, the inputs can therefore receive any type of signal — not just binary logic pulses.

PLEASE NOTE: This module requires connection to the Video Sync Generator by means of a Video Sync Distribution Chain Cable which must be purchased separately.

Video Divisions includes four Preset Modes and four Count Modes.

EXT MODE

In EXT mode, the eight outputs represent eight divisions of an input signal put into the Clock input. The current count is reset via a pulse at the Reset input. When in SQ+ count mode, the outputs count one after the other in a ring, so that only 1 output is high at any time. This function is similar to a gate sequencer. In DV+ count mode, the outputs represent binary divisions /2, /4, /8, /16, /32, /64, /128, /256. While in EXT mode, the SQ- and DV- modes are identical to SQ+ and DV+, except that the input clock is blanked so that clock pulses outside the viewable area of the screen are ignored. This is useful for correcting glitches in horizontal patterns.

FRM MODE

In FRM mode, the eight outputs represent divisions of the system’s frame rate clock. The count is reset via a pulse at the Reset input. When in SQ+/SQ- count modes, the outputs count one after the other in a ring, so that only 1 output is high at any time. This function is similar to a gate sequencer. In DV+/DV- count mode, the outputs represent binary divisions /2, /4, /8, /16, /32, /64, /128, /256.

X MODE

In X mode, the eight outputs produce vertical bars. The Clock and Reset inputs control a secondary counter which offsets the primary counter, to achieve modulation. When in SQ+/SQ- count modes, the outputs count one after the other in a ring, so that only 1 output is high at any time. This function is similar to a gate sequencer. In DV+/DV- count mode, the outputs represent binary divisions /2, /4, /8, /16, /32, /64, /128, /256. In SQ+/DV+ modes, the secondary counter shifts the vertical bars to the right. In SQ-/DV- modes, the secondary counter shifts the vertical bars to the left.

Y MODE

Y mode is identical to X mode, except horizontal instead of vertical bars are produced by the outputs.

We have produced an educational video introducing the basics of analogue video specifically for individuals interested in using our video synthesis system. Please let us know if it was useful to you!

This module is expensive and special order only due to the costs of the T-Bar element itself, which is a nearly $150 part. We built one for ourselves and love it, so if it’s worth the cost to you, we’ll happily build one for you as well!

Input sources are DC restored, sync clipped, and scaled to proper voltage levels before output for processing and patching throughout an LZX Visionary video synthesis system. In addition, three composite sync outputs can be used to feed Genlock inputs on external devices for synchronizing purposes. Also included is a YUV to RGB colorspace converter – with this feature, an external Component (YPrPb source) can be translated to the RGB colorspace internally.

Please be aware that this module does not include time base correction, frame synchronization, or composite color decoding features. If those features are required, you will need the Color Time Base Corrector module.

PLEASE NOTE: This module requires connection to the Video Sync Generator by means of a Video Sync Distribution Chain Cable which must be purchased separately.
