The difference between SECAM and PAL lies in the manner of how SECAM processes the color information of a broadcast signal. The PAL and NTSC
NTSC
NTSC, named after the National Television System Committee, is the analog television system that was used in most of the Americas (except Brazil, Argentina, Paraguay, Uruguay and French Guiana); Burma; South Korea; Taiwan; Japan; the Philippines; and some Pacific island nations and …
What is PAL and SECAM?
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. SECAM is an abbreviation for Sequential Color and Memory.
What is the difference between NTSC/PAL/luma and SECAM?
In any case, NTSC, PAL, and SECAM all have chrominance bandwidth (horizontal colour detail) reduced greatly compared to the luma signal. Spectrum of a System I television channel with PAL.
Is my camcorder PAL or SECAM?
Camcorders and VCRs of these standards sold in SECAM countries are internally PAL. The result could be converted back to SECAM in some models; most people buying such expensive equipment would have a multistandard TV set and as such would not need a conversion.
What is the difference between SECAM-D/K and PAL-B/G?
Instead, other European countries have changed completely from SECAM-D/K to PAL-B/G. The PAL-N system has a different sound carrier, and also a different colour subcarrier, and decoding on incompatible PAL systems results in a black-and-white image without sound.
What is QAM in PAL?
QAM stands for Quadrature Amplitude Modulation and it is the technique that is used both by NTSC and PAL in modulating the chrominance. SECAM didn’t use QAM, opting instead to use Frequency Modulation or FM. This gives SECAM superior signal over longer distances but increased crosstalk between the luminance and chrominance.
What is the difference between PAL and NTSC?
1.NTSC uses a refresh rate of 60Hz while PAL and SECAM use 50Hz. 2.NTSC has 525 lines while PAL and SECAM use 625 lines. 3.NTSC requires a tint control while PAL and SECAM doesn’t. 4.NTSC and PAL use QAM while SECAM uses FM. 5.NTSC and PAL sends the red and blue colors together while SECAM sends them alternately.
SECAM System Introduction
SECAM stands for Systeme Electronique couleur avec memoir or Sequential Color and Memory.
How Does SECAM Work?
SECAM takes each line of color and interlaces it sequentially with a line of luminance.
SECAM Bandwidth
According to the Broadcast Engineer’s Reference Book, the SECAM system used in the Middle East, North Africa and Mediterranean region has a bandwidth of 5MHz.
Difference Between SECAM and PAL : SECAM vs PAL
PAL and SECAM have a similarity. Both consist of 625 interlaced lines at 50 fields per second and displayed at 25 frames per second. Video resolution is 720 x 576.
SECAM vs NTSC
As has been explained, SECAM consists of 625 interlaced lines at 50 fields per second and a frame rate of 25 frames per second with a video resolution of 720 x 576.
SECAM Advantages and Disadvantages
As explained earlier, SECAM was driven by the need to improve on NTSC. It delivered on its promise of TV broadcast with superior color reproduction.
SECAM to NTSC Converter
What do you do if you have a SECAM tape and need to play it over an older NTSC VCR to an NTSC TV? As seen in the video below, you’ll see only jumping lines and hear only audio.
When was PAL introduced?
Introduced in Europe in the 1960's , PAL was an attempt to improve on the NTSC standard and it has remained the European standard (in most cases) up until this very day. PAL has varying versions including PAL B/G and PAL I. This system has a 50hz refresh rate.
What is a PAL TV?
When TV was first designed, there was a set of standards used to control how the information was sent from the broadcasting station to the TV, and how the TV interpreted this information into a picture on the TV screen. In North America, this standard is known as NTSC which stands for National Television Systems Committee. There are also two other types of standards used around the world; PAL (Phase Altering Line) and SECAM (Sequential Color with Memory). The systems used vary by country and/or region, but they all use one of the three standards: PAL, NTSC, or Secam. Digital cable, VHS, DVD, and Blu-ray also adhere to these color information standards. PAL TVs are only compatible with a PAL signal or other Pal components. The same is true for NTSC and SECAM. It's not possible to use a PAL TV with a NTSC Blu-ray Player or vice-versa. If you wanted to use your NTSC player to watch movies on a PAL or SECAM TV, you'd need to use an external video converter. Let's take a look at the differences betwen these three systems.
Can I use a PAL TV with a NTSC Blu-ray player?
It's not possible to use a PAL TV with a NTSC Blu-ray Player or vice-versa. If you wanted to use your NTSC player to watch movies on a PAL or SECAM TV, you'd need to use an external video converter. Let's take a look at the differences betwen these three systems.
What is a secam?
SECAM, also written SÉCAM ( French pronunciation: [sekam], séquentiel couleur à mémoire, French for sequential colour with memory ), is an analog color television system first used in France. It was one of three major color television standards, the others being PAL and NTSC .
Where is Secam used?
There are six varieties of SECAM: French SECAM (SECAM-L)h. French SECAM (SECAM-L) is used only in France, Luxembourg (only RTL9 on channel 21 from Dudelange) and Télé Monte-Carlo transmitters in the south of France. SECAM-B/G. SECAM-B/G is/was used in parts of the Middle East, former East Germany, Greece and Cyprus.
Why was Secam developed in France?
Some have argued that the primary motivation for the development of SECAM in France was to protect French television equipment manufacturers. However, incompatibility had started with the earlier unusual decision to adopt positive video modulation for French broadcast signals. The earlier systems System A and the 819-line systems were the only other systems to use positive video modulation. In addition, SECAM development predates PAL. NTSC was considered undesirable in Europe because of its tint problem requiring an additional control, which SECAM and PAL solved. Nonetheless, SECAM was partly developed for reasons of national pride. Henri de France's personal charisma and ambition may have been a contributing factor. PAL was developed by Telefunken, a German company, and in the post-war De Gaulle era there would have been much political resistance to dropping a French-developed system and adopting a German-developed one instead.
What is the Secam standard used in France?
The SECAM standard used in Metropolitan France used the SECAM-L and a variant of the channel information for VHF channels 2-10.
When was Secam created?
SECAM was inaugurated in France on 1 October 1967, on la deuxième chaîne (the second channel), now called France 2. A group of four suited men—a presenter ( Georges Gorse, Minister of Information) and three contributors to the system's development—were shown standing in a studio.
When was the first secam TV made?
Development of SECAM began in 1956 by a team led by Henri de France working at Compagnie Française de Télévision (later bought by Thomson, now Technicolor ). The technology was ready by the end of the 1950s, but this was too soon for a wide introduction. A version of SECAM for the French 819-line television standard was devised and tested, but not introduced. Following a pan-European agreement to introduce color TV only in 625 lines, France had to start the conversion by switching over to a 625-line television standard, which happened at the beginning of the 1960s with the introduction of a second network.
Is SECAM a pan-European standard?
All the countries using SECAM are currently in the process of conversion, or have already converted to Digital Video Broadcasting (DVB), the new pan-European standard for digital television. SECAM remained a major standard into the 2000s. This page primarily discusses the SECAM colour encoding system.
What are the SECAM patents?
The SECAM patents predate those of PAL by several years (1956 vs. 1962). Its creator, Henri de France, in search of a response to known NTSC hue problems, came up with ideas that were to become fundamental to both European systems, namely: 1) colour information on two successive TV lines is very similar and vertical resolution can be halved without serious impact on perceived visual quality 2) more robust colour transmission can be achieved by spreading information on two TV lines instead of just one 3) information from the two TV lines can be recombined using a delay line.
What is PAL analog?
The PAL system is analog. There was an attempt to manufacture equipment that digitizes the PAL signal in the 1980s, but it was not commercially successful. Digital devices such as digital television, modern game consoles, computers, etc., use color component systems where the R, G, and B signals are transmitted over three different cables, or Y' (luma), R' - Y', and B' - Y' (colour differences). In these cases only the number of total horizontal lines is taken into account: 625 in digital PAL and 525 in NTSC—and the frame rate: 25 frames/s in PAL Digital and 30 frames/s in digital NTSC. Systems using the MPEG-2 standard, such as DVD and satellite television, cable television, or digital terrestrial television (DTT) have practically nothing to do with PAL.
What is the PAL-N waveform?
In Argentina, Paraguay and Uruguay the PAL-N variant is used. It employs the 625 line/50 field per second waveform of PAL-B/G, D/K, H, and I , but on a 6 MHz channel with a chrominance subcarrier frequency of 3.582056 MHz (917/4*H) very similar to NTSC (910/4*H).
What is the difference between PAL and NTSC?
Interlacing frames gives a smoother motion with half the frame rate. NTSC is used with a frame rate of 60i or 30p whereas PAL generally uses 50i or 25p; both use a high enough frame rate to give the illusion of fluid motion. This is due to the fact that NTSC is generally used in countries with a utility frequency of 60 Hz and PAL in countries with 50 Hz, although there are many exceptions. Both PAL and NTSC have a higher frame rate than film which uses 24 frames per second. PAL has a closer frame rate to that of film, so most films are sped up 4% to play on PAL systems, shortening the runtime of the film and, without adjustment, slightly raising the pitch of the audio track. Film conversions for NTSC instead use 3:2 pull down to spread the 24 frames of film across 60 interlaced fields. This maintains the runtime of the film and preserves the original audio, but may cause worse interlacing artefacts during fast motion.
How many lines are in a PAL video?
The PAL colour system is usually used with a video format that has 625 lines per frame (576 visible lines, the rest being used for other information such as sync data and captioning) and a refresh rate of 50 interlaced fields per second (compatible with 25 full frames per second), such systems being B, G, H, I, and N (see broadcast television systems for the technical details of each format).
When was the first broadcast of the PAL system?
The first broadcasts began in the United Kingdom in July 1967, followed by West Germany later that year.
Who invented the PAL format?
PAL was developed by Walter Bruch at Telefunken in Hanover, West Germany, with important input from Dr. Kruse and Gerhard Mahler [ de]. The format was patented by Telefunken in 1962, citing Bruch as inventor, and unveiled to members of the European Broadcasting Union (EBU) on 3 January 1963.
Which is more common, PAL or SECAM?
PAL is much more common, covering most of Western Europe, China, India, Australia, most of Africa, and elsewhere. SECAM, the third system, is used in some other parts of Africa, Russia, and France. See the distribution of the video formats NTSC vs. PAL and SECAM on the map below.
What is SECAM in broadcasting?
There’s also a third system called SECAM (Séquentiel couleur à mémoire – “sequential color with memory” in French). It was developed in France as another alternative to NTSC and is used there and in Eastern Europe.
Why was the PAL format created?
Designed in the late 1950s in Germany, the PAL format was supposed to deal with certain weaknesses of NTSC, including signal instability under poor weather conditions, which was especially relevant for European broadcasters. The new standard was to solve the problem by reversing every other line in a TV signal and thus eliminating errors.
Why are Blu-rays still PAL?
The main reason for that is the enforcement of national copyright laws.
Is it better to use NTSC or PAL?
If you’re creating videos for global viewership, it’s safer to go with NTSC – as most PAL DVD players and VCRs are able to play NTSC video anyway, while NTSC platforms generally don’t work with PAL content.
