Production Studio: Cable news/weather show
The block diagram for this example shows a typical set up in a cable TV production studio, possibly one of
the numerous public access situations that cable systems have been mandated to make available to the
public as part of their license to operate in a town.
Key elements of this set up are: two component video studio cameras (for higher video quality and cleanest
chroma key); 2 instances of Datavideo handy DV Bank, for playback of background and tape segments;
composite video monitors of each channel through a compact 4 input passive switcher; audio mixer for talent
microphones and tape playback audio; high quality recording to a component video master recorder, with a
confidence monitor; separate program monitor.
The point of this set up is to produce and record, in one pass, a multi source program. Personnel required for
this operation, aside from the on camera talent, are 2 camera operators, a sound mixer, and the SE-800
operator, presumably you. This set up could easily be modified to produce a lecture/demonstration, cooking
show, or special effects segment, for example.
Backgrounds, such as weather maps and other full screen graphics, should be recorded to the DV Banks in
advance and played back on cue during the taping of the show. Additional graphics, such as lower thirds,
could be added through the SDI Overlay input during the taping or in postproduction.
Notes: the A+V function should be turned off, leaving the audio mix to the sound mixer operator; the Audio
Bus should be set to Aux 1 and Aux 2 only, routing the audio mixer’s output and the CD (for theme music if
needed) to the recording VCR; headphones should be set to monitor Main; black burst from the SE-800 can
be connected to the master recorder if necessary.
