2013 — Present: John Schmidt Audio/​Video Sys­tems Design & Consultation

  • Pro­vid­ing audio/​video/​RF sys­tems design, con­sul­ta­tion, commissioning/​setup, oper­a­tor train­ing, trou­bleshoot­ing services.
  • Broad­cast Sta­tion sys­tems design, main­te­nance, train­ing and troubleshooting.
  • Loca­tion record­ing, dig­i­ti­za­tion and media trans­fer, restora­tion of audio media.

19772013: ABC Tele­vi­sion Net­work, Senior Audio/​Video Sys­tems Engineer

Design of new state of the art dig­i­tal audio facil­i­ties for TV7/​TV1, used for The Katie Show, in 2011. Facil­i­ties now used for broad­cast­ing The View.

  • Three state-​of-​the-​art dig­i­tal audio consoles.
  • Exten­sive use of SDI embed­ded audio, AES audio, MADI (both fiber and coax), TDM. Exten­sive redun­dancy in audio/​video sig­nal flow.
  • Rock­net dis­trib­uted TDM: micro­phone, line inputs and out­puts on stu­dio floor con­nected to consoles.
  • Large split A/​V rout­ing switcher with TDM fiber embedding/​deembedding.
  • ENCO DAD net­worked sys­tem for music, audio ingest/​playout.

Replace­ment of the mas­ter pulse and time code gen­er­a­tion and dis­tri­b­u­tion sys­tem through­out the ABC tele­vi­sion plant, from 2005 to 2009

  • Triple redun­dant cesium stan­dards for fre­quency reference.
  • Quadru­ple redun­dant sync gen­er­a­tors, each with GPS for time reference.
  • Exten­sive dis­tri­b­u­tion sys­tem feed­ing over 100 facil­i­ties and devices, cut over from old sys­tem with no unplanned outages.
  • As a part of this project, redesigned and retimed slave ref­er­ence sys­tem within HD play­out facil­ity, to improve redundancy/​isolation between facil­i­ties and resolve tim­ing issues.

Dur­ing my 36 years at ABC, designed and super­vised con­struc­tion of four major audio sweet­en­ing rooms and new audio facil­i­ties in seven tele­vi­sion con­trol rooms, sev­eral more than once.

Con­verted ABC trans­mis­sion facil­i­ties to stereo in the 1980’s.

Spec­i­fied and designed cen­tral facil­i­ties with auto­mated play­out sys­tem and in-​house designed traf­fic sys­tem for the ABC Radio Net­work in the early 1980s.
