If headphone jack can be use to output a composite video?

[Doge99]

If we can output audio from 3.5 mm jack to full size RCA jack can it be possible to use headphone jack to output composite video as we plug the composite cable to audio we can hear audio and possible to convert video singal to audio and transmitted to the headphone jack to yellow RCA jack as composite video

I read this 5 times and still don't understand.

 

Cables and connectors are not related to what type of signal you want to pass through them. Like in files extensions - you can rename mp3 to avi, but this not change audio file into music video.

 

You can use any connectors for any type of signal - but it depends on device what type of signal you get, not by connector.

I meant that I use the headphone jack from pc or phone to output a composite video singal

Short answer is no. Jack itself would need to have connection surfaces for video. Like it needs them to handle both incoming and outgoing audio already on mobile and laptops. There's no retrofitting either.

 

Considering how low quality composite video is, and that we are moving to high bitrates on video, this won't be a thing in the future. Rather there will be better combo solutions using USB-C, HDMI, Thunderbolt and DisplayPort. Or something even better.

The iPod models with video could do this, but they were designed to do it.

But if I plug the composite video cable to RCA audio it is possible to hear sound. If the headphone jack with custom cable to send a audio singal that is capable of outputing composite video output. And to convert a normal crt TV to smart TV

It's not a question of the cables.

The device you're plugging into has to be designed to do it, like the ipod video I mentioned.

Jack needs to have contact surface for video signal, there's no way around it. It's same for every connector, which is also why they are now designed to handle any imaginable data transfer for future applications. For example phones would have HDMI or Lightning connection for video.

This is fake news.
3.5mm jacks are perfectly capable of outputting RCA video. However, the transmitting device would need to support the technology.
For example, the Nokia N8, E7, N808 Pureview, and most other Symbian devices could output video using their 3.5mm jack using the Nokia CA-75U adapter. The technology became obslote because of the rise of (micro/mini-)HDMI and later wireless technology.

From what I can see, he saying the same thing as you. Just explained differently.

I never said it wasn't.

Yes, thats what I did say.

Again, exactly what I did say. Which makes the question, did you actually read my post before start blaming?

Kind of off topic, but I had an old Aiptek camcorder (2006-2008ish) that can recieve a composite signal from a cable box, and connect via 4 pole 3.5mm jack. I used it for archiving cartoons I liked, and converted them for use on my iPod Nano 3rd gen.

You aren't getting the core issue here. The device will need to have jack with video signal capabilities. If it doesn't have that, video signal will not transfer through that port.

[Ross Siggers]

I think the confusion here is that OP isn't realising that you can have more than one different type of 3.5mm jack. The form factor is the same, but the internals and contact patches, pins, whatever. Would be different.

@xD Power Hole StickThat's why it can only carry video if the hardware is designed to do it, from the factory

That's the kind of cable you used with the video ipods. fwiw. I have it still in my "Bag O Misc Cables"™

You could take a composite video signal...which would come out of your device to a standard RCA cable and convert it to a 3.5 mm cable with something like this.

 

It's unlikely you'd have a device for the other end that takes a 3.5mm plug for video, but technically you can do that.
