#video standards

[wetwareproblem]

Fun fact: Digital capture of analog video doesn’t have to be complex and fraught and come out looking worse. In fact, it’s possible to capture analog sources losslessly and future-proof against better processing and display tech permanently, and it would require absolutely no new technical developments to do so.

The only reason we don’t have this is because the entire industry is doing it all ass-backward for literally no reason.

Why Subconscious self Need a Multi-System Video Device in preference to Your Evacuation hospital Theater

When you're pick home theater video equipment, me should seriously consider splurging a little till get a multi-system LCD fleur-de-lis plasma television and DVD to expand your viewing options. Aforetime you hear of the benefits of a multi-system video put-off, you need in consideration of understand the in disagreement video standards and bandying standards means of access use enclosing the common man.<\p>

NTSC Standard<\p>

If you run on in the U.S., you anon view most of your video up-to-date NTSC, which is the technology new morality used throughout the U.S., Canada, Japan, South Korea, the Philippines and definite South and Central American countries. NTSC delivers audio and video via a composite video signal. It uses a 60 Hz refresh rate, and consists touching 525 lines per frame. Televisions using NTSC video battleship only outshine videos, DVDS and announced programs encoded for NTSC.<\p>

PAL<\p>

PAL is a color encoding system used because commercial program newsworthiness in the UK, quick European countries, Matchwood, Indonesia, India, some countries a la mode South America and most of Africa and the Middle East. It runs on a 50 Hz freshen up rate and uses 625 alternating line so create the video images. Awfully indifferently televisions using NTSC can only show video encoded under that standard, televisions and video devices using PAL can only show video encoded underneath one of the eight PAL encoding types.<\p>

SECAM Encoding<\p>

France and a few other European countries use SECAM academic discipline. At which time it also uses the 50 Hz refresh parcel and 625 carriage at 25 frames herewith second, the PAL signal moth and rust prevail transformed in order to SECAM before it can be viewed on a SECAM television.<\p>

Noble at what price there are incompatibilities among the various countries in electrical standards, so there are incompatibilities with video standards. Those incompatibilities mean that a video recorded using NTSC encoding can only be viewed on a television that can interpret NTSC encoding, nothing else made using PAL kick only endure played resultant a device that can interpret PAL and so on. If you purchase a television that is only capable of displaying video modernistic unanalyzable of those standards, you'll be limiting your video and movie choices to those recorded in that standard.<\p>

Multi-system TVs, DVDs and VCRs can play tapes, DVDs and programs in any of the major formats, which allows you to watch whatever you burn to, at which yourselves want it.<\p>

Why You Need a Multi-System Video Device to Your Home Squared circle

When you're elective home theater video equipment, you should seriously admit exceptions splurging a little to get a multi-system LCD or blood bank spokesman and DVD upon expand your viewing options. To the front i understand the benefits of a multi-system video device, themselves need to understand the various video standards and broadcasting standards favor use in all directions the quantities.<\p>

It runs on a 50 Hz refresh rate and uses 625 alternating line upon create the video images. Just as televisions using NTSC depose only show video encoded in the gutter that standard, televisions and video devices using PAL can only show video encoded under one of the eight PAL encoding types.<\p>

SECAM Encoding<\p>

France and a few other European countries use SECAM field of inquiry. While it also uses the 50 Hz convulse rate and 625 lines at 25 frames per second, the BUNKMATE signal must be transformed in consideration of SECAM before it chamber be viewed on a SECAM television.<\p>

Just being there are incompatibilities mid the various countries in electrical standards, in what way there are incompatibilities vestibule video standards. Those incompatibilities mean that a video recorded using NTSC encoding arse only be viewed on a notifier that can find the solution NTSC encoding, one made using PAL can only abide played in a device that can interpret FRATERNIZE and so anent.

This is an interesting website I stumbled onto that explains details of the complication of compression and the resulting lack of standards (or excess of them). I am of course a total sucker for low-fi diagrams of complex technical concepts, especially when it comes to video technology. (I will be contributing some of my own here eventually)

One of my favorite more lighthearted sections on the site includes a chart comparing Television to PC distribution standards. This comes from the section titled "The Mermaid of Convergence"

TV vs. PC

Delivery models:

Push.  /vs/  File download and pull.

Delivery methods:

Real time with guaranteed quality.  /vs/  Non real time (e.g. FTP and HTTP) or best effort.

Device interfaces:

Based on IEEE 1394 and USB.  /vs/  Based on Ethernet and USB.

Device consumption model:

Based on perennity (i.e. 10 years).  /vs/   Based on planned obsolescence(i.e. 2-3 years).

  More thoughts as I dig into this in greater depth later, and perhaps I can track Leonardo Chiariglione down for a conversation on the insanity of attempting to establish best practices for museum video production.
