AJA D4E Serial Digital Encoder User Manual — Introduction

 

Introduction

 

The D4E SDI Encoder provides the lowest cost all-digital conversion of Component 
Serial Digital (SDI) to analog NTSC or PAL Composite or Y/C (S Video). The D4E 
is useful for monitoring, level and phase checking, dubbing, or desktop video 
applications. The D4E automatically adapts to NTSC or PAL video standards and 
outputs analog NTSC (525 line input) or PAL (625 line input). 

The D4E encodes the full dynamic range of input component video—values below 
black and above white are not clipped. In the NTSC mode, the 7.5 IRE pedestal can 
be disabled by external DIP switch selection. Narrow/wide H/V blanking are also 
configurable via DIP switches.
