Being from the metro Detroit area, we get Windsor's CBC feed and I have a bit of nostalgia for this screen because I'd watch their weekly late-night airings of Godzilla films on Saturdays back then (2005-06). Soon as the movie was done, this would show up. The tones always came off as a bit eerie, I think combined with the extra bar of space on top and detailed CBC logo animation compared to what a typical pattern looked like, so I'd immediately hop up to change the channel. XD Particularly remember this after a showing of Terror of Mechagodzilla because of how weird and downbeat _that_ movie is, along with how the channel stopped airing the movies after that. What a note to end on. Then I found they were airing in the same slot again a few years later, complete with the same screen afterward. By then I was in my mid-teens so it felt like a blast from the past
mrconancat haha I used to have to have this on to sleep as a kid, but I also used to stick my finger in my R2D2 lamp for fun electrocuting myself, was a strange kid, glad someone shares part of that weirdness. Lol,
What you call "dialing sounds" are actually command sequences sent down the network line to stations. It has been common practice for decades to use the same touch-tones for this as are used for telephone dialing, as the technology was easily adapted for that purpose: I worked for a radio station in the 1970s affiliated with Associated Press Radio for its network news and APR used touch-tones to allow stations to auto-record programming (sportcasts preceded with the "3" tone, for example).
K.M. Richards wow, I always wondered if it was my TV picking up neighbors phone dialing, haha, this always put me to sleep when I was a kid tho, weird I guess. Kind of like finding out Santa's not real all over again now that I know what the dials are, lol
This is known as Daul-Tone Multi-Frequency" or "DTMF". en.wikipedia.org/wiki/Dual-tone_multi-frequency_signaling Early cable TV channels used to use this method so local cable operators could automatically switch feeds to show local ads during break periods.
I recall CBET in Windsor used this version of the color bars shown here except for the inclusion of text in the center bordered by a transparent bar that says "CBC Windsor".
