Hamlet® DigiGen HD and SD SDI and Composite Video and Audio Signal Generator
Overview
DigiGen is a family of 1U rack-mountable multiformat video and audio signal generators. Members of the family include:
- DigiGen MultiGen HD and SD SDI and Composite Video and Audio Signal Generator
- DigiGen Axiom HD SDI Video Signal Generator
- DigiGen Index SD SDI, Composite Video and Audio Signal Generator
The DigiGen MultiGen is a feature rich, simple to use, multiformat video generator for use in control rooms and facilities where racking is available. The unit includes HD SDI, SD SDI and composite video generation with embedded audio and either AES/EBU or analog audio outputs. 16 video test signals are available for each of the outputs in digital this can be 525 or 625 and in analog either NTSC or PAL, including pathological, overlayed circles, moving pattern path activity signal, CRC codes, audio group selection audio line up tones, with or without an ident and a 16 character alpha/numeric ident which is scrollable.
