Low-definition television (LDTV) refers to television systems that have a lower screen resolution than standard-definition television systems. The term is usually used in reference to digital television, in particular when broadcasting at the same (or similar) resolution as low-definition analog TV systems. Mobile DTV systems usually transmit in low definition, as do all slow-scan TV systems.
The most common source of LDTV programming is the Internet, where mass distribution of higher-resolution video files could overwhelm computer servers and take too long to download. Many mobile phones and portable devices such as Apple’s iPod Nano, or Sony’s PlayStation Portable use LDTV video, as higher-resolution files would be excessive to the needs of their small screens (320×240 and 480×272 pixels respectively). The current generation of iPod Nanos have LDTV screens, as do the first three generations of iPod Touch and iPhone (480×320).
For the first years of its existence, YouTube offered only one, low-definition resolution of 320x240p at 30fps or less, only extending - first to widescreen 426×240, then to genuinely higher resolutions - once the video service had become well established, it could afford radically improved storage space and transmission bandwidth, and could rely on a good proportion of its users having high-speed internet connections. More recently, YouTube has also extended further into the LDTV realm by adding an even lower 256×144p resolution with a halved framerate - giving an overall effect reminiscent of early online video streaming attempts using RealVideo or similar, where 160×120p at single-figure fps was deemed acceptable - to cater to those whose network connections could not even widthstand the rigors of "240p".

Citra has just updated, allowing users to set their internal resolution from 240p, all the way up to 4K. Lets see just how different the native 240p 3DS resolution looks vs 4K! I originally rendered this at 4K 60fps to give the best clarity possible but youtube does not accept 4k 60fps apparently and only uploaded it in 1080p 60fps with no 4K option.

This video breaks down some of my experiments and results with capturing video from retro game consoles. I show you the hardware I will be using and talk about why I have made these choices. This video discusses RGB SCART, S-Video, Componenet, VGA, HDMI and how to upscale the lower 240p resolutions for capture.
This is a test to see if the recent Raspberry Pi's firmware modification to support 240p over Composite presents scanlines identical to those on a real NES using a standard definition television. The short answer is yes. Now to fix the geometry/emulator issues.

You NEED to view this at 60fps, or you will not see the effect. I will make a slowed down version later for 30fps viewers.
This is a test from crap quality to best quality. Just watch and maybe you will care more about the quality of vids cause 240p for me is soo 4 yrs ago.
Here's a video demonstrating Retropie running in 240p. My setup: Raspberry Pi - cheap HDMI to VGA converter - DIY VGA to SCART cable - SCART TV My video settings are: hdmi_group=2 hdmi_mode=87 hdmi_cvt=320 262 60 1 0 0 0 320x262 is the best and most compatible resolution because 262 is half the NTSC 60Hz interlaced resolution (525 lines) visible lines are 240p, the rest is for vertical blanking. My HDMI to VGA converter is a cheap one you find all over ebay with the analog audio output I've done a cable using Cat 5e UTP cable a VGA plug, a SCART plug, a audio 3.5mm stereo lead, a USB cable, 2 1k resistors and a 100 Ohm resistor, schematic here (solder side): I used a USB cable instead of the molex plug http://www.geocities.ws/podernixie/htpc/vga2euro.gif Cheap and easy, amazing ...
Tomorrow's coming 'round
A hair-pin curve in the road
She's got a run in her stocking
And she's missing the heel of her shoe
Got up this morning rolled out of bed
I spilled a diet coke
Called my mother said, "Hi"
What I meant to say was, "Why is your life a joke?"
Then, I went down to that ugly bar and
I clicked my heels three times just like you said
And I climbed that road to your empty house
The anticipation was a turn on
But you let me down
'Coz, I stood on that empty street alone
I said, "I'm ready for my close up now, Mr. Demille"
I waited for the light, but it never shone
Well I wonder what you do with that expensive piece of land
That overlooks a billion years of history
I have a sneaking suspicion, you will never understand
Hey maybe I'll see you down by the Rocky and Bullwinkle
And we can talk to that charlatan psychic
And she can paint a prettier picture of your future
'Coz that day in my life, that day in my life
I dreamt tomorrow, had a prettier face
I dreamt tomorrow, would have better things to say
Than, "You look like shit, what's your problem, bitch?
You're legs feel like sandpaper, you can't do anything right"
'Coz that day, never should have taken place
'Coz this day, in my life still cannot explain
Why I listened in the first place to you?
Oh yeah, something else
I hope one day you call up your father
And you have the guts to tell him, how he hurt you
And he made you hurt another
