Talk:Composite video

message: The process of modulating RF with the original video signal, and then demodulating the original signal again in the TV, introduces several losses. This conversion also typically adds noise or interference to the signal as well.  Other than noise, what are the losses? In theory, one can modulate an ideal carrier, and demodulate it again. The low signal levels of RF (it has to match what one could receive on an antenna) means noise is significant. (You can't escape thermal noise.) Generating a proper vestigial sideband signal is also tricky, but again, it can ideally be done without loss. Spectral errors aren't really losses, either. Gah4 (talk) 16:59, 28 May 2016 (UTC)
replies: text: In theory, no problem but in the real world it is an additional two steps and the advice to avoid unnecessary modulation/demodulation when possible is sound. ~Kvng (talk) 17:03, 25 April 2021 (UTC)
thread_title:  Noise 

message: The article indicates that Modern day devices with analog outputs have typically omitted the modulator option.  I suppose, but a very popular modern day device is the HDTV converter, which most often does have RF output.  But yes, I suspect that they are less common on DVD players and such than they used to be. Gah4 (talk) 22:40, 26 August 2019 (UTC)

thread_title:  modern day 

message: this part: "TV sets sold these days no longer have analog television tuners and cannot accept channel 3/4 from a modulator. But because composite video has a well-established market for both devices that convert it to channel 3/4 outputs, as well as devices that convert things like VGA to composite, it has offered opportunities to repurpose older composite monitors for newer devices."
Is nonsense. Maybe analogue TV tuners don't exist in the author's country anymore. But my brand new sony tv has one.
I assume by "channel 3/4" the writer is referring to north america.  — Preceding unsigned comment added by 2A02:A442:581E:1:3595:B7C4:F757:236D (talk) 22:19, 16 March 2022 (UTC)

replies: text: I think AHD is required to establish notability first, as indicated by its own article. I don't think that's warranted currently. --Zac67 (talk) 14:31, 20 June 2022 (UTC)

message: and I have been discussing recent changes to this article on my talk page at User_talk:Kvng#Composite_video. It would be better to have that discussion on this page but maybe too late for that. ~Kvng (talk) 18:47, 2 June 2024 (UTC)
