[QuadList] Question about NBC color TZ delay prior to Quad

[dcfwtx at aol.com]

Regarding Lenticular: Several years ago, a friend and co-worker of mine (since deceased), who was an engineer at NBC Burbank in the Lenticular film and RCA labs color conversion days of the VR 1000's in Burbank, gave me a rare publication (maybe it's available elsewhere?) titled: "Color Kinescope Recording on Embossed Film"; dated March 19, 1956. It's very descriptive with text, photos, and drawings (two attachments here). You may note that this publication date was very close to the date of the Ampex  demonstration of the quad machine in Chicago. 


In the coming weeks, I'll be posting some notes from conversations I've had with one of the last remaining individuals who were present at NBC Burbank during those initial color recording days (film and videotape).

That's a good question and people on the QuadList may have some information.  You can join the list and receive their answers by e-mail, or go here:

Generally, networks used a kinescope recorder to create a filmed recording of a high-resolution TV monitor. 
 

This could be done in black and white very easily, and was used for time-zone delay by some networks until they felt comfortable with videotape. 
 

Color kinescopes could also be made using color film, but I don't have any handy info about what NBC did as a regular practice. 
 

RCA/NBC did work on a lenticular film process that encoded color information into black and white film. The results weren't all that spectacular, I understand. 
 

Glad you've enjoyed the site. Thanks for the kind words.
