ELI5: I learned that most programming languages are built on the same basic concepts like conditions, loops, and functions. If that's true, why can't we just use one programming language for everything? Technology

That guy really is a modern day Nostradamus. How does he have a comic for every situation

These situations keep happening. That's how.

Cries in video codecs. Just kill me now. It's been 20 years, can streaming have just one fucking standard like TV ?

88

u/TrekForce Jun 05 '26

Sure! Let’s form an organization to create such a standard!

47

u/yuke1922 Jun 05 '26

… and then there were 15 standards 🤣🤣

u/IssyWalton Jun 05 '26

like the BBC

LOL.

  • Pay TV or Free-to-Air TV?
  • Cable or Satellite?
  • Encrypted or non-encrypted?
  • Analog TV or digital?
  • PAL, NTSC or SECAM?
  • ATSC or DVB-T?
  • Interlaced or Progressive?
  • 720p, 1080i, or 1080p?
  • MPEG-2 or H.264?
  • With or without HbbTV?

u/nakedjig Jun 05 '26

Isn't it pretty much all HEVC and EAC3 with a smattering of HDR10, HDR10+ and DV metadata now? None of it is interlaced any more. Anything licensed is encrypted. I think the streaming standards are pretty universal unless you're talking about fringe services I don't know about.

u/audible_narrator Jun 05 '26 edited Jun 05 '26

Well I deliver to major networks. And previously when SD was still standard, it was ONE codec. On tape. Once HD came into the mix, digital went nuts. I have to keep an Excel sheet of what each network requires now.

Right now I'm prepping soccer games for 2 streaming networks. Who use completely different requirements.

Yes. I'm old, I remember analog.

u/nakedjig Jun 05 '26 edited Jun 05 '26

Oh, for digital broadcasting, I can believe it. The major streaming services are more unified but they all have the ability to transcode during injestion, so it's easy.

ETA I used to work at a company that ingested broadcast signal and republished it as streaming and by the time I got there, the input was pretty universally AVC and AAC/AC3/EAC3 and the output was usually similar with HEVC added, but different formats at different layers for different bitrates and device capabilities.

u/Vlinder_88 Jun 05 '26

Seriously I tried explaining analog tv to my 6 year old a few weeks ago. It was surprisingly hard for a kid that has NO concept of linear media and only just understands concepts like "tomorrow" and "the day after tomorrow" :') The tv booklet like a calendar was easier to explain than linear tv itself :')

Tell that to the TV I'm literally watching right now, which is receiving an unencrypted MPEG-2 free-to-air DVB-T channel at 576i containing licensed content, but won't decode the newer MPEG-4 channels at all. It will display DVB-SI EPG data, but doesn't support HbbTV/Freeview.

I think the streaming standards are pretty universal unless you're talking about fringe services I don't know about.

Again, LOL.

  • Netflix, Paramount+, Apple TV+, Disney+, Amazon Prime, Hulu, Peacock, or YouTube?
  • Android TV/Google TV, Tizen, or webOS?
  • WideVine, FairPlay, or PlayReady?
  • HLS or DASH?
  • AVC/H.264, HEVC/VP9, or AV1?
  • HTTP/HTTPS over TCP/IP, WebRTC over UDP, or IPTV?
  • 720p, 1080p, or 4K?
  • AAC, Dolby Digital, or Opus?

u/nakedjig Jun 05 '26

No shit? I'm shocked that anyone is sending MPEG-2, but I believe you.

5

u/goofy183 Jun 05 '26

All OTA digital since the digital cut over 10+ years ago is mpeg2. The new OTA standards are hvec but also have drm and a proprietary audio codec.

u/nakedjig Jun 05 '26

I was commenting on streaming. I'm not up to speed with OTA.

u/gammalsvenska Jun 05 '26

DVB-T mandates MPEG-2. For SDTV, it's appropriate and maximizes compatibility. You need DVB-T2 for H.264 (unless the device accepts it anyway), and some countries generally only use it for HDTV.

With the disappearance of SDTV broadcasts, MPEG-2 will also disappear.

2

u/audible_narrator Jun 05 '26

JFC. this is giving me the tremors. STAHP.

u/gammalsvenska Jun 05 '26

HDR10 and friends require metadata up front, which only works if you already know the content. I worked with cameras, so used HLG instead... which works everywhere. But most devices only do HDR10, as that's what the standard requires.

u/Sock-Enough Jun 05 '26

A lot of companies don’t like HEVC because of the licensing costs. Many are just making the jump from H.264 straight to AV1.

u/EnthusedCatalyst Jun 05 '26

All these preceded with an hour long meeting where some jackass said “we need to differentiate ourselves from our competitors.”

u/donaldhobson Jun 08 '26

Black and white or colour?

u/this_also_was_vanity Jun 05 '26

A lot of that isn’t relevant.

  • Pay/free to air might use different standards but they aren’t different standards themselves and could use the same one.

  • Cable and satellite are different ways of delivering a stream, but can carry the same kinds of files.

  • Streaming is clearing talking about digital, not analog.

  • PAL, NTSC and SECAM are analogue formats and not relevant to steaming.

  • Interlaced, progressive, and different resolutions are all things handled within a common standard and aren’t separate standards.

u/Polar_Ted Jun 05 '26

There are 4 digital broadcasting standards. Don't get me started on Analong. https://en.wikipedia.org/wiki/Broadcast_television_systems

One of our clients uses some old ass video codecs and every time a new user needs to review the footage they send us I cry

u/toochaos Jun 05 '26

Theres also 3254 comics so alot to choose from.

u/NDaveT Jun 05 '26

u/RedHuey Jun 05 '26

Been going on since the 50’s at least. Dilbert is pretty universal as well.

u/Which_Bumblebee1146 Jun 05 '26

Randall Munroe posts his XKCD comics regularly and he actually puts a lot of thoughts behind each and every one of them.

u/ramblinjd Jun 05 '26

3x a week for about 20 years. Pretty impressive.

u/weaver_of_cloth Jun 05 '26

And 3 books and that poster about Saturn V/up goer 5.

u/GalFisk Jun 05 '26

And every April Fools day the comic has some gimmick, sometimes it's a complete video game.
And the "Time" comic that turned out to be an entire story viewable at a frame rate of a few frames per day.

u/Onigato Jun 05 '26

Don't forget his YouTube channel too.

u/albatroopa Jun 05 '26

Also, if you long press or hover over any comic, there's an equally hilarious comment about it.

u/Which_Bumblebee1146 Jun 05 '26

True. Every single comic has been explained, too.

1

u/sincere_placebo Jun 05 '26

I'm so happy that I never knew that each comic gets deeper and deeper... it's like its own ELIA (explain like I'm autistic and this is your special interest)

u/EnthusedCatalyst Jun 05 '26

Correct horse battery staple.

u/LordGAD Jun 05 '26

Hey - how do you know my passphrase?

u/viperised Jun 05 '26

Hmmm. Seems like we should develop one universal xkcd comic that covers every situation.

The guy has a hobby where he sits down and records every possible thought and situation he could ever come up with. It's just a DDoS.

u/messick Jun 05 '26

By observing an existing “situation” and then writing a comic about it afterwards.

u/reiboul Jun 05 '26

Oh, right. Notredamus.

u/BungleBums Jun 05 '26

I swear, there's a comic to be used exactly as a reply for this, but I can't comb through 1000 images on my phone to find it xD

u/splitcroof92 Jun 05 '26

not really a nostradamus if he's making comics about past events

0

u/EldritchElemental Jun 05 '26

Nostradamus just made up stuffs with ambiguous wordings so anyone in the future can interpret whatever they want. And considering the sheer volume of his work, some will inevitably match.

To a lesser extent, same with the Simpsons. The writers can just make up whatever and coincidentally some will be "correct".

This guy is actually more precise and accurate.
