There isn't. The BBC channels are carried by commercial broadcasters as part of the UK licencing policies and there is no incentive to add delayed channels.
The BBC iPlayer provides a number of programmes on demand after their original broadcast times and they can be found on the BBC web site.

Televisions are complex devices and are the result of a century of invention and development. However, the principles remain the same and are very simple. A picture is captured by a camera by breaking the image into a series of dots or pixels across the width of the picture. Each string of dots makes up one line of the image. In an HD signal, there are 1920 dots in each line and 1080 lines from top to bottom. As each dot is captured, the amount of red, green and blue light is recorded as three numbers. These numbers are sent as a continuous stream of data. When the whole image has been sent, the whole process starts over to deliver the next image. The images are captured 25 or 30 times every second. The television receives the stream of data and decodes it into a brightness for each of the three colors in every pixel. There are many other processes that go on alongside this process but the description shows the main principle - Identical to the one used by John Logie Baird in 1925.
A television works by sending and receiving electronic signals.
I feel your pain......
i waiting in anticipation too. Have you seen the new promotional clip?
It looks absolutely incredible! My guess is that it will be aired this summer-

- Some people prefer the look of older TVs to new ones.
- Older TVs sometimes work better in deep fringe reception locations
- Older TVs often have manual tuning dials so they can be adjusted quickly if
a channel starts breaking up.
- Older TVs usually have a VHF tuner, making it possible to use old game consoles, VCRs
and other VHF equipment, as some newer TV's don't have a VHF tuner.
- Many old TVs use 300ohm antenna inputs, so older antennas and accessories can easily be used with them.
- Many older TVs are very inexpensive and can be a comfortable solution to watching TV provided there is analogue TV stations in your area or you have a DTV top box
compatible with your TV. Very old TVs can be expensive because of their rarity, but 60's
and 70's TVs can be as cheap as $5 for a middle-sized set.
- Old TVs are very easy to find.
- Old TVs are collectible and some can be considered priceless or an important part of
- Older TVs provide a warm, soft image which many people prefer over the sharp, crisp
picture of newer TVs.
Ah yes, May 2nd, the biggest sports day in recent memory. A day in which all sports collide in an epic spectacle of sports, sports, sports! The culmination coming as Floyd Mayweather fights Manny Pacquiao, a fight that has taken 5 years to come to fruition. Boxing fans have been patient. Many disappointed it took so long. I haven't been quiet about my dislike for Mayweather. Here's a man who's twice been convicted of assaulting women, and accused many more times. His lack of respect for my gender makes it easy to root for whomever is fighting him. And I'm not saying Pacquiao is a man without his own problems, but I hope when the final bell rings, Manny is left standing, victorious.
John Logie Baird demonstrated his Televisor system to the public in March 1925 inside Selfridges, a London department store. Two years later in 1927 he showed the "phonovision" system of recording TV.
Designs and patents for electro-mechanical television systems had been proposed as early as 1884 by German student Paul Gottlieb Nipkow but never built. It was this invention, the Nipkow disc, that Baird used for his televisor.
An all-electronic moving-image television system somewhat similar to that used today was invented and demonstrated in 1929 by Philo Farnsworth.
In the same year, the BBC in London began the first television broadcasts available to the public. They used Baird's Televisor system which remained in use until 1936 when the BBC moved to an all electronic higher definition system. Television broadcasts were halted in 1939 at the start of World War II, the same year that RCA began their broadcasts in the US, representing the start of publicly available television in North America.
In 1946, scientists at the laboratories of the Radio Corporation of America (RCA) developed the Image Orthocon Tube, a far more sensitive light sensor than previous cameras used. The new tube made production far easier and effective.
John Logie Baird (August 13, 1888 - June 14, 1946) a Scottish engineer invented the TV on the 26th January 1926 and it was demonstrated a year later in 1927 the "phonovision" system of recording TV.
In 1927, Philo Farnsworth made the world's first working television. In 1928, Baird then demonstrated the first color tv :)
Television has been around since 1925. It was then that John Logie Baird demonstrated the first television system to the public. His system was an electro-mechanical device that used a spinning disc to create a moving image. It was used for the very first public broadcasts in 1929 by the BBC in London.
Across the Atlantic, Philo Farnsworth was also working on similar systems, as was Vladimir Zworykin. Farnsworth carried out his first demonstration of another electro-mechanical system in 1927 but two years later, he had eliminated the moving parts and therefore is credited with the first person to produce a fully electronic system. (Some sources say Zworykin did the same, around 1928 for RCA in New York -- he was on the east coast, and Farnsworth was on the west coast, but both were experimenting with electronic, rather than mechanical TV.)
By the mid 1930s, the BBC had given up on Baird's system and replaced it with a fully electronic version. Baird and Farnsworth worked together in a bid to use their new system but the BBC chose a competitive system. The BBC first went on the air with regular programming in 1936 (the opening song was "Magic Rays of Light").
In America, scheduled public broadcasts did not start until 1939, at the New York World's Fair, where NBC debuted its WNBT-TV. This was partly due to additional development work by Farnsworth but legal challenges to patents were the major factor in the delay. American televisions did not really take off in availability and popularity till after World War II has ended, at which time, a number of stations in most major cities went on the air.
John Logie Baird showed a working television system to the public in 1925.
Baird was a Scottish engineer and inventor of the world's first working television system in Hastings, England, in 1923. His public demonstration subsequently took place in Selfridges, a department store in London England, during March 1925. The system was successful enough to become commercialized, and the BBC began the world's first regular television broadcasts in January 1929, using Baird's system.
Baird's "Televisor" was an electro-mechanical system and used a rotating disc called a Nipkow disc. Paul Nipkow, a German inventor patented the disc in 1885 as a means to capture an image for telegraphic transmission. His invention was largely ignored and Nipkow never built the disc himself. The patent expired in 1899 and Baird adopted the device for use with moving images.
In 1927, Baird transmitted a long-distance television signal over 438 miles (705 km) of telephone line between London and Glasgow; Baird transmitted the world's first long-distance television pictures to the Central Hotel at Glasgow Central Station.
In 1928, Baird demonstrated the first color television. Like his monochrome television, it used rotating discs to build the image. The three discs added red, green and blue light together to create a full-color image. Although cumbersome, it demonstrated the principles of color television that have remained in use to this day.
On the other side of the Atlantic, several inventors were working on the same idea. One was Charles Francis Jenkins, who put a number of mechanical television stations on the air in the eastern United States in the mid-1920s. Also, there was Philo Farnsworth, a west-coast inventor whose first demonstration of television was in 1927. Like Baird's system, it was electro-mechanical, but by 1929 he had eliminated the moving parts of his system to create the world's first fully electronic system.
Farnsworth's developments were adopted by The Radio Corporation of America, one of the major radio broadcasters in the US at the time (Better known as RCA), but commercial television broadcasts in the US were delayed because of legal battles over patents. It was in 1939 that RCA began the first commercial and public television broadcasts using Farnsworth's system.
During the same time period, Vladimir Zworykin, a Russian engineer working for Westinghouse in Pittsburgh, was working on television. He was granted several patents, but didn't quite reach a full working television system. However, in the 1930s he developed the "Iconoscope," a form of cathode ray tube to capture moving images electronically. This paved the way for better-quality image capture.
Since those pioneering years of the 1920s, the development of television has been rapid and consistent. The BBC adopted a fully electronic system of television in 1936 and Baird's system fell into disuse after that time.
The 1940s saw dramatic improvements in the sensitivity and quality of camera tubes. The 1950s marked the first color broadcasts in the US, while Britain and Europe began seeing television in color during the 1960s.
Further developments in the 1980s and 1990s introduced high definition television standards and flat screen televisions. In the 21st century we enjoy high-definition television on larger and brighter screens than ever before. Despite the advances, the principle of television today is still based firmly on the early work of Baird and Farnsworth.
it was 1824
If you are using an analog TV, there are basically no more analog TV broadcasts other than a very few low power transmitters.
From now on, you need a digital receiver. They can be obtained from electronic retailers for a few dollars and will allow you to receive digital broadcasts in the same way as analog broadcasts.
Alternatively, you could use cable or a satellite service although these options will involve additional charges.
The final option is to use an Internet based television receiver. AppleTV is one of several devices that may work for you.
Most electronics stores will be able to tell you what options you have for your area but be aware that they will be keen to sell a solution to you. Consider their advice carefully but don't be pushed into an immediate purchase when you speak to them.

Color television made its debut in the US in the early 1950s. It was a commercial failure and was withdrawn after only a few months. By 1955 a national standard for color television was agreed and RCA launched color services. The new color broadcasts and televisions were a rapid success and by 1956, sales of color televisions had grown dramatically.
The color standard used was called NTSC and is the standard definition color encoding system that is still used today, more than half a century on.
any broadcasting of specific subject materials can be education but educational broadcasting is general held to be radio, television, etc, airing of deliniated formal educational material
I think the best way to request the channel, which broadcast it and get a copy from their record library.
In 1928, Philo Farnsworth made the world's first working television system.
It all has to do with the message it holds.
To broadcast pictures, television stations use the methods of progressive and interleaf scanning.
Make that interlace scanning.
Laminate the page(s) it is printed on. Though I have not tried this, Hairspray is used as a fixative for pencil drawings. This could possibly work. It wouldn't make the paper waterproof, which is your biggest problem. Lamination, as said above, is the answer.
No, no one got that far in the game except for the Bishop kids. They were the first to play it and they were close but didnt win it.

Guillermo Gonzalez Camarena (1917-1965), is a Mexican national from Guadalajara Jalisco. His project was rejected by the Mexican authorities and had to go to the United States.
In 1934 he made his first TV when he was 17 years old, later he patented his color TV in Mexico and the US. He holds patents to various color television systems from 1940, 1942, 1960 and 1962. In 1940 at the age of 22, Guillermo Gonzalez Camarena obtained US Patent #2,296,022 for his Trichromatic system used for color television transmissions.
In August 31, 1946 he sent his first color transmition from his lab in the offices of The Mexican League of Radio Experiments in Lucerna St. #1, in Mexico City. The video signal was transmited in 115 MHz. and the audio in a band of 40 meters. RCA claims they did it in 1946 but Camarena's patent has an earlier month. Also, there are previous attempts or designs.
Guillermo Camarena's work was impressive but some wrongly attribute the first color television to Camarena. However, Scotsman John Logie Baird sent images by a mechanical colour television in 1928, before his electro-mechanical black-and-red system was adopted by the BBC in 1929. This is the first demonstration of color television and precedes Camarena's patents by twelve years.
In 1943, he suggested to the Hankey Postwar TV Commitee that postwar TV should be 1000 lines 3d, color and Black-and-White compatible. The commitee did not think this was possible, but Baird made it work before his death in 1946, a week after he demonstrated the above system, which was the first fully electronic color television in the world. He sent famous actors and moving cartoons through the air in colour and his images would have been simlar to the HDTV of today. If you search for "John Logie Baird Telechrome" you will be able to see the images reproduced. His system was almost flat screen.
