118-650: Default Amiga screen modes are directly compatible with TVs in the region in which the computer was sold, so that the user could connect the computer to a common TV if no monitor was available. In the PAL region, the Amiga could be connected directly to the standardized SCART RGB connector on the TV via an adapter cable sold by Commodore, providing superior image quality. Alternatively, Commodore sold an adapter (the A520 ), that attached to

236-693: A "Bruch system" would probably not have sold very well ("Bruch" is the German word for "breakage" ). The first broadcasts began in the United Kingdom in July 1967, followed by West Germany at the Berlin IFA on August 25. The BBC channel initially using the broadcast standard was BBC2 , which had been the first UK TV service to introduce "625-lines" during 1964. The Netherlands and Switzerland started PAL broadcasts by 1968, with Austria following

354-410: A 6 MHz channel with a chrominance subcarrier frequency of 3.582056 MHz (917/4*H) similar to NTSC (910/4*H). On the studio production level, standard PAL cameras and equipment were used, with video signals then transcoded to PAL-N for broadcast. This allows 625 line, 50 frames per second video to be broadcast in a 6 MHz channel, at some cost in horizontal resolution . In Brazil, PAL

472-853: A Christian in the event of victory against the Visigothic Kingdom , which was said to have guaranteed the battle. Clovis regained the southwest from the Visigoths and was baptised in 508. Clovis I was the first Germanic conqueror after the Fall of the Western Roman Empire to convert to Catholic Christianity; thus France was given the title "Eldest daughter of the Church" by the papacy, and French kings called "the Most Christian Kings of France". The Franks embraced

The revolt of May 1968 had an enormous social impact; it was a watershed moment when a conservative moral ideal (religion, patriotism, respect for authority) shifted to a more liberal moral ideal (secularism, individualism, sexual revolution). Although

708-584: A European signal. The BBC tested their pre-war (but still broadcast until 1985) 405-line monochrome system ( CCIR System A ) with all three colour standards including PAL, before the decision was made to abandon 405 and transmit colour on 625/ System I only. Many countries have turned off analogue transmissions, so the following does not apply anymore, except for using devices which output RF signals, such as video recorders . The majority of countries using or having used PAL have television standards with 625 lines and 50 fields per second. Differences concern

826-887: A PAL-N TV broadcast can be sent to anyone in European countries that use PAL (and Australia/New Zealand, etc.) and it will display in colour. This will also play back successfully in Russia and other SECAM countries, as the USSR mandated PAL compatibility in 1985—this has proved to be very convenient for video collectors. People in Argentina, Paraguay and Uruguay usually own TV sets that also display NTSC-M, in addition to PAL-N. DirecTV also conveniently broadcasts in NTSC-M for North, Central, and South America. Most DVD players sold in Argentina, Paraguay and Uruguay also play PAL discs—however, this

944-423: A comb-like effect known as Hanover bars on larger phase errors. Thus, most receivers now use a chrominance analogue delay line , which stores the received colour information on each line of display; an average of the colour information from the previous line and the current line is then used to drive the picture tube . The effect is that phase errors result in saturation changes, which are less objectionable than

1062-759: A combination of social, political and economic factors, which the Ancien Régime proved unable to manage. A financial crisis and social distress led in May 1789 to the convocation of the Estates General , which was converted into a National Assembly in June. The Storming of the Bastille on 14 July led to a series of radical measures by the Assembly, among them the abolition of feudalism , state control over

1180-569: A coup and civil war. During the May 1958 crisis , the weak Fourth Republic gave way to the Fifth Republic , which included a strengthened presidency. The war concluded with the Évian Accords in 1962 which led to Algerian independence , at a high price: between half a million and one million deaths and over 2 million internally-displaced Algerians. Around one million Pied-Noirs and Harkis fled from Algeria to France. A vestige of empire

1298-538: A delay line and suffering from the “ Hannover bars ” effect. An example of this solution is the Kuba Porta Color CK211P set. Another solution was to use a 1H analogue delay line to allow decoding of only the odd or even lines. For example, the chrominance on odd lines would be switched directly through to the decoder and also be stored in the delay line. Then, on even lines, the stored odd line would be decoded again. This method (known as 'gated NTSC')

These computers could also output directly to the VGA monitors that by then had become commonplace, provided they were configured to output in a VGA compatible resolution and refresh rate. To enable this, Commodore sold an adapter which, like the A520, attached to the video connector to provide a standard VGA connector. This video technology article

1534-454: A major issue considering Europe's geographical and weather-related particularities. To overcome NTSC's shortcomings, alternative standards were devised, resulting in the development of the PAL and SECAM standards. The goal was to provide a colour TV standard for the European picture frequency of 50  fields per second (50  hertz ), and finding a way to eliminate the problems with NTSC. PAL

1652-532: A period of economic prosperity and cultural and scientific flourishing known as the Belle Époque . France was one of the major participants of World War I , from which it emerged victorious at great human and economic cost. It was among the Allies of World War II , but it surrendered and was occupied in 1940. Following its liberation in 1944 , the short-lived Fourth Republic was established and later dissolved in

PAL-M (a broadcast standard) however should not be confused with "PAL 60" (a video playback system—see below). PAL television receivers manufactured since the 1990s can typically decode all of the PAL variants except, in some cases PAL-M and PAL-N. Many such receivers can also receive Eastern European and Middle Eastern SECAM, though rarely French-broadcast SECAM (because France used

3186-513: Is only used on UHF. Although System I is used on both bands, it has only been used on UHF in the United Kingdom. The PAL-L (Phase Alternating Line with CCIR System L broadcast system) standard uses the same video system as PAL-B/G/H (625 lines, 50 Hz field rate, 15.625 kHz line rate), but with a larger 6 MHz video bandwidth rather than 5.5 MHz and moving the audio subcarrier to 6.5 MHz.

This excluded very basic PAL decoders that relied on the human eye to average out the odd/even line phase errors, and in the early 1970s some Japanese set manufacturers developed basic decoding systems to avoid paying royalties to Telefunken . These variations are known as " PAL-S " (for "simple" or "Volks-PAL"), operating without

8496-711: The area in 51 BC, leading to a distinct Gallo-Roman culture . In the Early Middle Ages , the Franks formed the Kingdom of Francia , which became the heartland of the Carolingian Empire . The Treaty of Verdun of 843 partitioned the empire, with West Francia evolving into the Kingdom of France . In the High Middle Ages , France was a powerful but decentralized feudal kingdom, but from

8614-399: The audio carrier frequency and channel bandwidths. The variants are: Systems B and G are similar. System B specifies 7 MHz channel bandwidth, while System G specifies 8 MHz channel bandwidth. Australia and China used Systems B and D respectively for VHF and UHF channels. Similarly, Systems D and K are similar except for the bands they use: System D is only used on VHF, while System K

8732-514: The climate became milder; from approximately 7,000 BC, this part of Western Europe entered the Neolithic era, and its inhabitants became sedentary . After demographic and agricultural development between the 4th and 3rd millennia BC, metallurgy appeared , initially working gold, copper and bronze , then later iron . France has numerous megalithic sites from the Neolithic, including

8850-411: The colour carrier is a result of 283.75 colour clock cycles per line plus a 25 Hz offset to avoid interferences. Since the line frequency (number of lines per second) is 15625 Hz (625 lines × 50 Hz ÷ 2), the colour carrier frequency calculates as follows: 4.43361875 MHz = 283.75 × 15625 Hz + 25 Hz. The frequency 50 Hz is the optional refresh frequency of

8968-415: The colour decoder circuitry to distinguish the phase of the R − Y ′ {\displaystyle R-Y'} vector which reverses every line. For PAL-B/G the signal has these characteristics. (Total horizontal sync time 12.05 μs) After 0.9 μs a 2.25 ± 0.23 μs colourburst of 10 ± 1 cycles is sent. Most rise/fall times are in 250 ± 50  ns range. Amplitude

9086-822: The constitutional July Monarchy ; French troops began the conquest of Algeria . Unrest led to the French Revolution of 1848 and the end of the July Monarchy. The abolition of slavery and introduction of male universal suffrage was re-enacted in 1848. In 1852, president of the French Republic, Louis-Napoléon Bonaparte , Napoleon I's nephew, was proclaimed emperor of the Second Empire , as Napoleon III. He multiplied French interventions abroad, especially in Crimea , Mexico and Italy . Napoleon III

9204-498: The course of the defeat in the Algerian War . The current Fifth Republic was formed in 1958 by Charles de Gaulle . Algeria and most French colonies became independent in the 1960s, with the majority retaining close economic and military ties with France . France retains its centuries-long status as a global centre of art , science , and philosophy . It hosts the fourth-largest number of UNESCO World Heritage Sites and

9322-508: The digital signals ( 576i or 480i ) to the analog standards to assure compatibility. CCIR 625/50 and EIA 525/60 are the proper names for these (line count and field rate) standards; PAL and NTSC on the other hand are methods of encoding colour information in the signal. "PAL-D", "PAL-N", "PAL-H" and "PAL-K" designations on this section describe PAL decoding methods and are unrelated to broadcast systems with similar names. The Telefunken licence covered any decoding method that relied on

9440-526: The empire, leaving England and Aquitaine to the Plantagenets. Charles IV the Fair died without an heir in 1328. The crown passed to Philip of Valois , rather than Edward of Plantagenet, who became Edward III of England . During the reign of Philip, the monarchy reached the height of its medieval power. However Philip's seat on the throne was contested by Edward in 1337, and England and France entered

9558-613: The ensuing uprising of European monarchies against his rule, Napoleon was defeated. About a million Frenchmen died during the Napoleonic Wars . After his brief return from exile, Napoleon was finally defeated in 1815 at the Battle of Waterloo , and the Bourbon monarchy was restored with new constitutional limitations. The discredited Bourbon dynasty was overthrown by the July Revolution of 1830, which established

9676-433: The equivalent hue changes of NTSC. A minor drawback is that the vertical colour resolution is poorer than the NTSC system's, but since the human eye also has a colour resolution that is much lower than its brightness resolution, this effect is not visible. In any case, NTSC, PAL, and SECAM all have chrominance bandwidth (horizontal colour detail) reduced greatly compared to the luma signal. The 4.43361875 MHz frequency of

9794-594: The forefront of the development of a supranational European Union , notably by signing the Maastricht Treaty in 1992, establishing the eurozone in 1999 and signing the Treaty of Lisbon in 2007. France has fully reintegrated into NATO and since participated in most NATO-sponsored wars. Since the 19th century, France has received many immigrants , often male foreign workers from European Catholic countries who generally returned home when not employed. During

9912-976: The four major rivers Seine , the Loire , the Garonne , the Rhône and their tributaries, whose combined catchment includes over 62% of the metropolitan territory. The Rhône divides the Massif Central from the Alps and flows into the Mediterranean Sea at the Camargue . The Garonne meets the Dordogne just after Bordeaux, forming the Gironde estuary , the largest estuary in Western Europe which after approximately 100 kilometres (62 mi) empties into

10030-479: The largest among European Union members. France's total land area, with its overseas departments and territories (excluding Adélie Land ), is 643,801 km (248,573 sq mi), 0.45% of the total land area on Earth. France possesses a wide variety of landscapes, from coastal plains in the north and west to mountain ranges of the Alps in the southeast, the Massif Central in the south-central and Pyrenees in

10148-466: The meaning "free" was adopted because, after the conquest of Gaul , only Franks were free of taxation, or more generally because they had the status of freemen in contrast to servants or slaves. The etymology of *Frank is uncertain. It is traditionally derived from the Proto-Germanic word * frankōn , which translates as "javelin" or "lance" (the throwing axe of the Franks was known as

10266-652: The mid-14th to the mid-15th centuries, France was plunged into a dynastic conflict with England known as the Hundred Years' War . In the 16th century, the French Renaissance saw culture flourish and a French colonial empire rise. Internally, France was dominated by the conflict with the House of Habsburg and the French Wars of Religion between Catholics and Huguenots . France was successful in

10384-432: The monitor to be able to create an illusion of motion, while 625 lines means the vertical lines or resolution that the PAL system supports. The original colour carrier is required by the colour decoder to recreate the colour difference signals. Since the carrier is not transmitted with the video information it has to be generated locally in the receiver. In order that the phase of this locally generated signal can match

10502-400: The monochrome luma signal, with the three RGB colour channels mixed down onto two, U {\displaystyle U} and V {\displaystyle V} . Like NTSC, PAL uses a quadrature amplitude modulated subcarrier carrying the chrominance information added to the luma video signal to form a composite video baseband signal. The frequency of this subcarrier

10620-647: The most-used language in diplomacy, science, and literature until the 20th century. France took control of territories in the Americas, Africa and Asia. In 1685, Louis XIV revoked the Edict of Nantes , forcing thousands of Huguenots into exile and published the Code Noir providing the legal framework for slavery and expelling Jews from French colonies. Under the wars of Louis XV (r. 1715–1774), France lost New France and most Indian possessions after its defeat in

10738-458: The newly established kingdoms. These victories led to the worldwide expansion of French revolutionary ideals and reforms, such as the metric system , Napoleonic Code and Declaration of the Rights of Man. In 1812 Napoleon attacked Russia , reaching Moscow. Thereafter his army disintegrated through supply problems, disease, Russian attacks, and finally winter. After this catastrophic campaign and

10856-494: The next year. Telefunken PALcolour 708T was the first PAL commercial TV set. It was followed by Loewe -Farbfernseher S 920 and F 900 . Telefunken was later bought by the French electronics manufacturer Thomson . Thomson also bought the Compagnie Générale de Télévision where Henri de France developed SECAM, the first European Standard for colour television. Thomson, now called Technicolour SA, also owns

10974-507: The off-and-on Hundred Years' War . Boundaries changed, but landholdings inside France by English Kings remained extensive for decades. With charismatic leaders, such as Joan of Arc , French counterattacks won back most English continental territories. France was struck by the Black Death , from which half of the 17 million population died. The French Renaissance saw cultural development and standardisation of French, which became

11092-631: The palace (head of household). One mayor of the palace, Charles Martel , defeated an Umayyad invasion of Gaul at the Battle of Tours (732). His son, Pepin the Short , seized the crown of Francia from the weakened Merovingians and founded the Carolingian dynasty . Pepin's son, Charlemagne , reunited the Frankish kingdoms and built an empire across Western and Central Europe . Proclaimed Holy Roman Emperor by Pope Leo III and thus establishing

11210-631: The primary source of legitimacy , undermined the power of and support for the monarchy and was a factor in the Revolution. The French Revolution was a period of political and societal change that began with the Estates General of 1789 , and ended with the coup of 18 Brumaire in 1799 and the formation of the French Consulate . Many of its ideas are fundamental principles of liberal democracy , while its values and institutions remain central to modern political discourse. Its causes were

11328-586: The remainder of Gaul and overcame a revolt by Gallic chieftain Vercingetorix in 52 BC. Gaul was divided by Augustus into provinces and many cities were founded during the Gallo-Roman period , including Lugdunum (present-day Lyon ), the capital of the Gauls. In 250–290 AD, Roman Gaul suffered a crisis with its fortified borders attacked by barbarians . The situation improved in the first half of

11446-454: The revolt was a political failure (the Gaullist party emerged stronger than before) it announced a split between the French and de Gaulle, who resigned. In the post-Gaullist era, France remained one of the most developed economies in the world but faced crises that resulted in high unemployment rates and increasing public debt. In the late 20th and early 21st centuries, France has been at

11564-514: The same, resulting in the different sound carrier. 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. The PAL-M system has a different sound carrier and a different colour subcarrier, and does not use 625 lines or 50 frames/second. This would result in no video or audio at all when viewing

11682-549: The second-largest behind the British Empire . Including metropolitan France, the total area reached almost 13 million square kilometres in the 1920s and 1930s, 9% of the world's land. Known as the Belle Époque , the turn of the century was characterised by optimism, regional peace, economic prosperity and technological, scientific and cultural innovations. In 1905, state secularism was officially established . France

11800-472: The southwest. Due to its numerous overseas departments and territories scattered across the planet, France possesses the second-largest exclusive economic zone (EEZ) in the world, covering 11,035,000 km (4,261,000 sq mi). Its EEZ covers approximately 8% of the total surface of all the EEZs of the world. Metropolitan France has a wide variety of topographical sets and natural landscapes. During

11918-664: The state and reinforced royal power. He destroyed castles of defiant lords and denounced the use of private armies. By the end of the 1620s, Richelieu established "the royal monopoly of force". France fought in the Thirty Years' War , supporting the Protestant side against the Habsburgs. From the 16th to the 19th century, France was responsible for about 10% of the transatlantic slave trade . During Louis XIV 's minority, trouble known as The Fronde occurred. This rebellion

12036-549: The technical details of each format). This ensures video interoperability. However, as some of these standards ( B/G/H , I and D/K ) use different sound carriers (5.5 MHz, 6.0 MHz and 6.5 MHz respectively), it may result in a video image without audio when viewing a signal broadcast over the air or cable. Some countries in Eastern Europe which formerly used SECAM with systems D and K have switched to PAL while leaving other aspects of their video system

12154-405: The transmission of the signal by cancelling them out, at the expense of vertical frame colour resolution. Lines where the colour phase is reversed compared to NTSC are often called PAL or phase-alternation lines, which justifies one of the expansions of the acronym, while the other lines are called NTSC lines. Early PAL receivers relied on the human eye to do that cancelling; however, this resulted in

12272-412: The transmitted information, a 10 cycle burst of colour subcarrier is added to the video signal shortly after the line sync pulse, but before the picture information, during the so-called back porch . This colour burst is not actually in phase with the original colour subcarrier, but leads it by 45 degrees on the odd lines and lags it by 45 degrees on the even lines. This swinging burst enables

12390-530: The unoccupied territory. Free France , the government-in-exile led by  Charles de Gaulle , was set up in London. From 1942 to 1944, about 160,000 French citizens, including around 75,000 Jews , were deported to death and concentration camps . On 6 June 1944, the Allies invaded Normandy , and in August they invaded Provence . The Allies and French Resistance emerged victorious, and French sovereignty

12508-668: The world . Metropolitan France shares borders with Belgium and Luxembourg to the north, Germany to the northeast, Switzerland to the east, Italy and Monaco to the southeast, Andorra and Spain to the south, and a maritime border with the United Kingdom to the northwest. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and

12626-464: Was invaded by Germany and defended by Great Britain at the start of World War I in August 1914. A rich industrial area in the north was occupied. France and the Allies emerged victorious against the Central Powers at tremendous human cost. It left 1.4 million French soldiers dead, 4% of its population. Interwar was marked by intense international tensions and social reforms introduced by

12744-521: Was a founding member of NATO and attempted to regain control of French Indochina , but was defeated by the Viet Minh in 1954. France faced another anti-colonialist conflict in Algeria , then part of France and home to over one million European settlers ( Pied-Noir ). The French systematically used torture and repression, including extrajudicial killings to keep control. This conflict nearly led to

12862-484: Was adopted by Sony on their 1970s Trinitron sets ( KV-1300UB to KV-1330UB ), and came in two versions: " PAL-H " and " PAL-K " (averaging over multiple lines). It effectively treated PAL as NTSC, suffering from hue errors and other problems inherent in NTSC and required the addition of a manual hue control. Most PAL systems encode the colour information using a variant of the Y'UV colour space. Y ′ {\displaystyle Y'} comprises

12980-591: Was developed by Walter Bruch at Telefunken in Hanover, West Germany , with important input from Gerhard Mahler  [ de ] . The format was patented by Telefunken in December 1962, citing Bruch as inventor, and unveiled to members of the European Broadcasting Union (EBU) on 3 January 1963. When asked why the system was named "PAL" and not "Bruch" the inventor answered that

13098-681: Was divided into Germanic kingdoms and a remaining Gallo-Roman territory. Celtic Britons , fleeing the Anglo-Saxon settlement of Britain , settled in west Armorica ; the Armorican peninsula was renamed Brittany and Celtic culture was revived. The first leader to unite all Franks was Clovis I , who began his reign as king of the Salian Franks in 481, routing the last forces of the Roman governors in 486. Clovis said he would be baptised

13216-531: Was driven by feudal lords and sovereign courts as a reaction to the royal absolute power . The monarchy reached its peak during the 17th century and reign of Louis XIV. By turning lords into courtiers at the Palace of Versailles , his command of the military went unchallenged. The "Sun King" made France the leading European power. France became the most populous European country and had tremendous influence over European politics, economy, and culture. French became

13334-698: Was executed in January 1793. After another revolt in June 1793 , the constitution was suspended and power passed from the National Convention to the Committee of Public Safety . About 16,000 people were executed in a Reign of Terror , which ended in July 1794 . Weakened by external threats and internal opposition, the Republic was replaced in 1795 by the Directory . Four years later in 1799,

13452-536: Was introduced. Named PALplus , it was defined by ITU recommendation BT.1197-1. It was developed at the University of Dortmund in Germany , in cooperation with German terrestrial broadcasters and European and Japanese manufacturers. Adoption was limited to European countries. With the introduction of digital broadcasts and signal sources (ex: DVDs , game consoles), the term PAL was used imprecisely to refer to

13570-414: Was its precursor. During the 9th and 10th centuries, threatened by Viking invasions , France became a decentralised state: the nobility's titles and lands became hereditary, and authority of the king became more religious than secular, and so was less effective and challenged by noblemen. Thus was established feudalism in France. Some king's vassals grew so powerful they posed a threat to the king. After

13688-591: Was restored with the Provisional Government of the French Republic (GPRF). This interim government, established by de Gaulle, continued to wage war against Germany and to purge collaborators from office . It made important reforms e.g. suffrage extended to women and the creation of a social security system. A new constitution resulted in the Fourth Republic (1946–1958), which saw strong economic growth ( les Trente Glorieuses ). France

13806-670: Was set to impose a carbon tax in 2009; however, the plan was abandoned due to fears of burdening French businesses. Forests account for 31 per cent of France's land area—the fourth-highest proportion in Europe—representing an increase of 7 per cent since 1990. French forests are some of the most diverse in Europe, comprising more than 140 species of trees. France had a 2018 Forest Landscape Integrity Index mean score of 4.52/10, ranking it 123rd globally. There are nine national parks and 46 natural parks in France. A regional nature park (French: parc naturel régional or PNR)

13924-467: Was unseated following defeat in the Franco-Prussian War of 1870, and his regime replaced by the Third Republic . By 1875, the French conquest of Algeria was complete, with approximately 825,000 Algerians killed from famine, disease, and violence. France had colonial possessions since the beginning of the 17th century, but in the 19th and 20th centuries its empire extended greatly and became
