What is NTSC and PAL?
NTSC is the video standard commonly used in North America and most of South America. PAL is the video standard which is popular in most of the European and Asian countries. The difference between NTSC and PAL is the transmission of number of frames per second. In NTSC, 30 frames are transmitted per second.
What is PAL format used for?
PAL is an abbreviation for Phase Alternate Line. This is the video format standard used in many European countries. A PAL picture is made up of 625 interlaced lines and is displayed at a rate of 25 frames per second.
Does PAL still exist?
The faults (or features) of NTSC and PAL are dictated mainly by how analog TVs function. Digital TVs are fully capable of pushing past these limitations (specifically frame rates), but we still see NTSC and PAL in use today.
What is NTSC PAL and SECAM?
NTSC uses a refresh rate of 60Hz while PAL and SECAM both use a refresh rate of 50Hz. The refresh rate is the number of times the image on the screen changes to simulate the illusion of motion. NTSC thus has more fluid motion because of the 10 more frames per second.
Which is better PAL or NTSC?
Is NTSC or PAL better quality? If you want to create videos for worldwide viewership, it is a safe bet to opt for NTSC as PAL VCRs and DVD players can play NTSC videos. But PAL comes with 625 lines of resolution, whereas NTSC has 525 only. More lines can provide better quality, so PAL is of better quality.
What is PAL connection?
Phase Alternating Line (PAL) is a colour encoding system for analogue television. It was one of three major analogue colour television standards, the others being NTSC and SECAM.
Why does France use SECAM?
NTSC was considered undesirable in Europe because of its tint problem, requiring an additional control, which SECAM (and PAL) solved. Some have argued that the primary motivation for the development of SECAM in France was to protect French television equipment manufacturers.
Is HDMI a PAL or NTSC?
IIRC, there are NTSC resolutions, and PAL resolutions in HDMI. So technically, it's neither PAL nor NTSC over HDMI, it's MPEG video.
What NTSC means?
National Television Standards CommitteeThe NTSC (National Television Standards Committee) was responsible for developing, in 1953, a set of standard protocol for television (TV) broadcast transmission and reception in the United States.
Why is PAL slower than NTSC?
The first is the fact NTSC ran at 60Hz and PAL at 50Hz, which meant many games launched in PAL regions ran 17 percent slower than they did in the US and Japan. PAL also has a higher vertical resolution of 576 lines compared to NTSC's 480, which meant PAL gamers got big black borders.
How many Hertz is a SECAM?
Frame Rates PAL/SECAM uses exactly 25 fps. These frame rates are based on the local frequency of alternating current (AC) electrical power: 60 Hz in the States; 50 Hz in most of the rest of the world.
Where is NTSC used?
NTSC is used in the United States, Canada, Japan, South Korea, Mexico, Central America, parts of South America and some other countries. PAL is used in Great Britain, most countries in Europe and Africa, Australia, the Middle East, China, India and some other countries.
What causes phase errors in radio frequency transmission?
In radiofrequency data transmission, phase errors are common and therefore caused by signal delays in arrival or processing. Phase errors in the analog video cause an error in color tone, adversely affecting image quality.
What is PAL line?
The lines in which the phase is reversed from how it will be transmitted in NTSC are usually called PAL lines, and the ones to match are called NTSC lines. PAL’s operating system means it is a more complex application than the NTSC system.
What is the basic concept of signal transmission based on?
However, the basic concepts of signal transmission are based on the NTSC system.
Which adaptations were used to keep some of the technical aspects of the SECAM system in PAL?
Some Eastern European countries that stopped using the SECAM system used adaptations PAL-D or K to keep some of the technical aspects of SECAM in PAL.
Is compression factor lower in NTSC or PAL?
On the other hand, since the compression factor is lower in NTSC, less quality loss is experienced compared to PAL.
Is NTSC better than PAL?
The only way NTSC is superior to PAL is because of its higher refresh rate, there is no flickering sensation that can be seen in the peripheral field of view when watching TV on a large screen.

60 Hz operation
During the mid-1990s, the practice of modifying consoles such as the Super NES and Mega Drive to allow 60 Hz operation became somewhat common among PAL gamers, due to the rise in NTSC/60 Hz capable PAL TVs and the relatively simple nature of the modifications.
Criticism of PAL region video games
Games ported to PAL have historically been known for having game speed and frame rates inferior to their NTSC counterparts. Since the NTSC standard is 60 fields/30 frames per second but PAL is 50 fields/25 frames per second, games were typically slowed by approximately 16.7% in order to avoid timing problems or unfeasible code changes.

Färgkodning
PAL jämfört med NTSC
PAL mot SECAM
Phase Alternate Line (PAL) är ett analogt TV-färgsystem för utsändning av TV i stora delar av världen. Andra vanligt förekommande analoga tv-system är SECAM och NTSC. Sverige övergick 2005 till DVB-T, men PAL används dock än idag i Sverige.

Signaldetaljer för PAL
På 1950-talet, när de västeuropeiska länderna planerade för att införa färg-TV, fick de brottas med problemet att NTSC uppvisade ett flertal svagheter, inklusive färgtonsskiftningar under dåliga mottagnings- och sändningsförhållanden, vilket gav systemet det komiska öknamnet ”Never The Same Color”. På grund av dessa svagheter påbörjades utvecklingen av SECAM- och PAL-standarderna. Målet var att erbjuda en färg-tv-standard för den europeiska bildfrekvensen 50 del…

Grunderna i PAL och NTSC är väldigt lika; en kvadraturamplitudmodulerad bärvåg som bär krominansinformationen vilken läggs till luminansvideosignalen för att skapa en grundläggande kompositvideo. Frekvensen för denna bärvåg är 4,43361875 MHz för PAL jämfört med 3,579545 MHz för NTSC. SECAM å andra sidan, använder FM för dess två alternativa färgbärvågor 4,25000 MHz och 4,40…

NTSC-mottagare har en färgtonskontroll för att utföra färgkorrektion manuellt. Om detta inte justeras korrekt, kan färgerna bli felaktiga. PAL-standarden tar bort färgtonsfel automatiskt genom att utnyttja fasväxling av färgsignalen (se ovan), så en färgtonskontroll är helt överflödig. Krominansfasfel i PAL-systemet elimineras genom att använda en 1H fördröjningslinje vilket resulterar i något lägre mättnad, vilket är mindre noterbart för ögat än NTSC:s färgmättnadsfel.
