Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion.

History[link]

Video technology was first developed for cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.

Video recorders sold for $50,000 in 1956, and videotape cost $300 per one-hour reel.^[1] However, prices steadily dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) tapes to the public. After the invention of the DVD in 1997 and Blu-ray Disc in 2006, sales of videotape and tape equipment plummeted.

Later advances in computer technology allowed computers to capture, store, edit and transmit video clips.

Characteristics of video streams[link]

Number of frames per second[link]

Frame rate, the number of still pictures per unit of time of video, ranges from six or eight frames per second (frame/s) for old mechanical cameras to 120 or more frames per second for new professional cameras. PAL (Europe, Asia, Australia, etc.) and SECAM (France, Russia, parts of Africa etc.) standards specify 25 frame/s, while NTSC (USA, Canada, Japan, etc.) specifies 29.97 frame/s. Film is shot at the slower frame rate of 24photograms/s, which complicates slightly the process of transferring a cinematic motion picture to video. The minimum frame rate to achieve the illusion of a moving image is about fifteen frames per second.

Interlaced vs progressive[link]

Video can be interlaced or progressive. Interlacing was invented as a way to reduce flicker in early mechanical and CRT video displays without increasing the number of complete frames per second, which would have required sacrificing image detail in order to remain within the limitations of a narrow bandwidth. The horizontal scan lines of each complete frame are treated as if numbered consecutively and captured as two fields: an odd field (upper field) consisting of the odd-numbered lines and an even field (lower field) consisting of the even-numbered lines.

Analog display devices reproduce each frame in the same way, effectively doubling the frame rate as far as perceptible overall flicker is concerned. When the image capture device acquires the fields one at a time, rather than dividing up a complete frame after it is captured, the frame rate for motion is effectively doubled as well, resulting in smoother, more life-like reproduction (although with halved detail) of rapidly moving parts of the image when viewed on an interlaced CRT display, but the display of such a signal on a progressive scan device is problematic.

NTSC, PAL and SECAM are interlaced formats. Abbreviated video resolution specifications often include an i to indicate interlacing. For example, PAL video format is often specified as 576i50, where 576 indicates the total number of horizontal scan lines, i indicates interlacing, and 50 indicates 50 fields (half-frames) per second.

In progressive scan systems, each refresh period updates all of the scan lines of each frame in sequence. When displaying a natively progressive broadcast or recorded signal, the result is optimum spatial resolution of both the stationary and moving parts of the image. When displaying a natively interlaced signal, however, overall spatial resolution will be degraded by simple line doubling and artifacts such as flickering or "comb" effects in moving parts of the image will be seen unless special signal processing is applied to eliminate them. A procedure known as deinterlacing can be used to optimize the display of an interlaced video signal from an analog, DVD or satellite source on a progressive scan device such as an LCD Television, digital video projector or plasma panel. Deinterlacing cannot, however, produce video quality that is equivalent to true progressive scan source material.

Aspect ratio[link]

Comparison of common cinematography and traditional television (green) aspect ratios

Aspect ratio describes the dimensions of video screens and video picture elements. All popular video formats are rectilinear, and so can be described by a ratio between width and height. The screen aspect ratio of a traditional television screen is 4:3, or about 1.33:1. High definition televisions use an aspect ratio of 16:9, or about 1.78:1. The aspect ratio of a full 35 mm film frame with soundtrack (also known as the Academy ratio) is 1.375:1.

Ratios where the height is taller than the width are uncommon in general everyday use, but do have application in computer systems where the screen may be better suited for a vertical layout. The most common tall aspect ratio of 3:4 is referred to as portrait mode and is created by physically rotating the display device 90 degrees from the normal position. Other tall aspect ratios such as 9:16 are technically possible but rarely used. (For a more detailed discussion of this topic please refer to the page orientation article.)

Pixels on computer monitors are usually square, but pixels used in digital video often have non-square aspect ratios, such as those used in the PAL and NTSC variants of the CCIR 601 digital video standard, and the corresponding anamorphic widescreen formats. Therefore, an NTSC DV image which is 720 pixels by 480 pixels is displayed with the aspect ratio of 4:3 (which is the traditional television standard) if the pixels are thin and displayed with the aspect ratio of 16:9 (which is the anamorphic widescreen format) if the pixels are fat.

Color space and bits per pixel[link]

Example of U-V color plane, Y value=0.5

Color model name describes the video color representation. YIQ was used in NTSC television. It corresponds closely to the YUV scheme used in NTSC and PAL television and the YDbDr scheme used by SECAM television.

The number of distinct colors that can be represented by a pixel depends on the number of bits per pixel (bpp). A common way to reduce the number of bits per pixel in digital video is by chroma subsampling (e.g. 4:4:4, 4:2:2, 4:2:0/4:1:1).

Video quality[link]

Video quality can be measured with formal metrics like PSNR or with subjective video quality using expert observation.

The subjective video quality of a video processing system may be evaluated as follows:

• Choose the video sequences (the SRC) to use for testing.
• Choose the settings of the system to evaluate (the HRC).
• Choose a test method for how to present video sequences to experts and to collect their ratings.
• Invite a sufficient number of experts, preferably not fewer than 15.
• Carry out testing.
• Calculate the average marks for each HRC based on the experts' ratings.

Many subjective video quality methods are described in the ITU-T recommendation BT.500. One of the standardized method is the Double Stimulus Impairment Scale (DSIS). In DSIS, each expert views an unimpaired reference video followed by an impaired version of the same video. The expert then rates the impaired video using a scale ranging from "impairments are imperceptible" to "impairments are very annoying".

Video compression method (digital only)[link]

A wide variety of methods are used to compress video streams. Video data contains spatial and temporal redundancy, making uncompressed video streams extremely inefficient. Broadly speaking, spatial redundancy is reduced by registering differences between parts of a single frame; this task is known as intraframe compression and is closely related to image compression. Likewise, temporal redundancy can be reduced by registering differences between frames; this task is known as interframe compression, including motion compensation and other techniques. The most common modern standards are MPEG-2, used for DVD, Blu-ray and satellite television, and MPEG-4, used for AVCHD, Mobile phones (3GP) and Internet.

Bit rate (digital only)[link]

Bit rate is a measure of the rate of information content in a video stream. It is quantified using the bit per second (bit/s or bps) unit or Megabits per second (Mbit/s). A higher bit rate allows better video quality. For example VideoCD, with a bit rate of about 1 Mbit/s, is lower quality than DVD, with maximum bit rate of 10.08 Mbit/s for video. HD (High Definition Digital Video and TV) has a still higher quality, with a bit rate of about 20 Mbit/s.

Variable bit rate (VBR) is a strategy to maximize the visual video quality and minimize the bit rate. On fast motion scenes, a variable bit rate uses more bits than it does on slow motion scenes of similar duration yet achieves a consistent visual quality. For real-time and non-buffered video streaming when the available bandwidth is fixed, e.g. in videoconferencing delivered on channels of fixed bandwidth, a constant bit rate (CBR) must be used.

Stereoscopic[link]

Stereoscopic video can be created using several different methods:

• two channels — a right channel for the right eye and a left channel for the left eye. Both channels may be viewed simultaneously by using light-polarizing filters 90 degrees off-axis from each other on two video projectors. These separately polarized channels are viewed wearing eyeglasses with matching polarization filters.
• one channel with two overlaid color coded layers. This left and right layer technique is occasionally used for network broadcast, or recent "anaglyph" releases of 3D movies on DVD. Simple Red/Cyan plastic glasses provide the means to view the images discretely to form a stereoscopic view of the content.
• One channel with alternating left/right frames for each eye, using LCD shutter glasses which read the frame sync from the VGA Display Data Channel to alternately cover each eye, so the appropriate eye sees the correct frame. This method is most common in computer virtual reality applications such as in a Cave Automatic Virtual Environment, but reduces the effective video framerate to one-half of normal (for example, from 120 Hz to 60 Hz).

Blu-ray Discs greatly improve the sharpness and detail of the two-color 3D effect in color coded stereo programs. See articles Stereoscopy and 3-D film.

Video formats[link]

There are different layers of video transmission and storage, each with its own set of formats to choose from.

For transmission, there is a physical connector and signal protocol ("video connection standard" below). A given physical link can carry certain "display standards" which specify a particular refresh rate, display resolution, and color space.

Many analog and digital recording formats are in use, and digital video clips can also be stored on a computer file system as files which have their own formats. In addition to the physical format used by the data storage device or transmission medium, the stream of ones and zeros that is sent must be in a particular digital "video encoding", of which a number are available.

Transport medium[link]

Video can be transmitted or transported in a variety of ways. Wireless broadcast as an analog or digital signal. Coaxial cable in a closed circuit system can be sent as analog interlaced 1 volt peak to peak with a maximum horizontal line resolution up to 480. Broadcast or studio cameras use a single or dual coaxial cable system using a progressive scan format known as SDI serial digital interface and HD-SDI for High Definition video. The distances of transmission are somewhat limited depending on the manufacturer the format may be proprietary. SDI has an negligible lag and is uncompressed. There are initiatives to use the SDI standards in closed circuit surveillance systems, for Higher Definition images, over longer distances on coax or twisted pair cable. Due to the nature of the higher bandwidth needed, the distance the signal can be effectively sent is a half to a third of what the older interlaced analog systems supported.^[2]

Video connectors, cables, and signal standards[link]

Video display standards[link]

Digital television[link]

New formats for digital television broadcasts use the MPEG-2 video codec and include:

• ATSC - USA, Canada, Korea
• Digital Video Broadcasting (DVB) - Europe
• ISDB - Japan
  • ISDB-Tb - Uses the MPEG-4 video codec. Brazil, Argentina
• Digital Multimedia Broadcasting (DMB) - Korea

Analog television[link]

Analog television broadcast standards include:

• FCS - USA, Russia; obsolete
• MAC - Europe; obsolete
• MUSE - Japan
• NTSC - USA, Canada, Japan
• PAL - Europe, Asia, Oceania
  • PAL-M - PAL variation. Brazil, Argentina
  • PALplus - PAL extension, Europe
• RS-343 (military)
• SECAM - France, Former Soviet Union, Central Africa

An analog video format consists of more information than the visible content of the frame. Preceding and following the image are lines and pixels containing synchronization information or a time delay. This surrounding margin is known as a blanking interval or blanking region; the horizontal and vertical front porch and back porch are the building blocks of the blanking interval.

Many countries are planning a digital switchover soon.

Randolph Frederick "Randy" Pausch^[2] (October 23, 1960 – July 25, 2008) was an American professor of computer science and human-computer interaction and design at Carnegie Mellon University (CMU) in Pittsburgh, Pennsylvania.

Pausch learned that he had pancreatic cancer in September 2006, and in August 2007 he was given a terminal diagnosis: "3 to 6 months of good health left". He gave an upbeat lecture titled "The Last Lecture: Really Achieving Your Childhood Dreams" on September 18, 2007, at Carnegie Mellon, which became a popular YouTube video and led to other media appearances. He then co-authored a book called The Last Lecture on the same theme, which became a New York Times best-seller.

Pausch died of complications from pancreatic cancer on July 25, 2008.

Early life[link]

Pausch was born in Baltimore, Maryland, and grew up in Columbia, Maryland.^[2] After graduating from Oakland Mills High School in Columbia, Pausch received his bachelor's degree in computer science from Brown University in May 1982 and his Ph.D. in computer science from Carnegie Mellon University in August 1988.^{[3][not in citation given]} While completing his doctoral studies, Pausch was briefly employed at Xerox Palo Alto Research Center and Adobe Systems.^[4]

Computer science career[link]

Pausch was an assistant and associate professor in the Department of Computer Science at the University of Virginia's School of Engineering and Applied Science from 1988 until 1997. While there, he completed sabbaticals at Walt Disney Imagineering and Electronic Arts (EA). In 1997, Pausch became Associate Professor of Computer Science, Human-Computer Interaction and Design, at Carnegie Mellon University. He was a co-founder in 1998, along with Don Marinelli, of CMU's Entertainment Technology Center (ETC), and he started the Building Virtual Worlds^[5] course at CMU and taught it for 10 years. He consulted with Google on user interface design and also consulted with PARC, Imagineering, and Media Metrix.^[4] Pausch is also the founder of the Alice software project.^[6] He received the National Science Foundation Presidential Young Investigator Award and was a Lilly Foundation Teaching Fellow.^[7] Pausch was the author or co-author of five books and over 70 articles.

Pausch received two awards from ACM in 2007 for his achievements in computing education: the Karl V. Karlstrom Outstanding Educator Award and the ACM Special Interest Group on Computer Science Education Award for Outstanding Contributions to Computer Science Education.^[8] He was also inducted as a Fellow of the ACM in 2007.

Cancer and death[link]

Pausch was diagnosed with pancreatic cancer^[9][10] and underwent a Whipple procedure (pancreaticoduodenectomy) on September 19, 2006, in an unsuccessful attempt to halt his pancreatic cancer.^[11] He was told in August 2007 to expect a remaining three to six months of good health. He soon moved his family to Chesapeake, Virginia, a suburb near Norfolk, to be close to his wife's family. On March 13, 2008, Pausch advocated for greater federal funding for pancreatic cancer before the United States Senate Appropriations Subcommittee on Labor, Health and Human Services, Education, and Related Agencies.^[12] In the week prior to this, he had been hospitalized in order to have needle aspiration of pleural effusion in his right lung.^[13]

On May 2, 2008, a positron emission tomography (PET) scan showed that he had very tiny (5 millimetres (0.20 in) or less) metastases in his lungs and some lymph nodes in his chest. He also had some metastases in his peritoneal and retroperitoneal cavities. On June 26, 2008, Pausch indicated that he was considering stopping further chemotherapy because of the potential adverse side effects. He was, however, considering some immuno-therapy-based approaches.^[14] On July 24, on behalf of Pausch, a friend anonymously posted a message on Pausch's webpage stating that a biopsy had indicated that the cancer had progressed further than what was expected from recent PET scans and that Pausch had "taken a step down" and was "much sicker than he had been". The friend also stated that Pausch had then enrolled in a hospice program designed to provide palliative care to those at the end of life.^[14]

Pausch died from pancreatic cancer at his family's home in Chesapeake, Virginia on July 25, 2008, at the age of 47. He is survived by his wife, Jai, and their three children, Dylan, Logan, and Chloe.^[15]

[edit] Really Achieving Your Childhood Dreams

Pausch delivered his "Last Lecture", titled Really Achieving Your Childhood Dreams, at CMU on September 18, 2007.^[16] He gave an abridged version of his speech on the Oprah show in October 2007.^[17][18] The talk was modeled after an ongoing series of lectures where top academics are asked to think deeply about what matters to them, and then give a hypothetical "final talk", with a topic such as "what wisdom would you try to impart to the world if you knew it was your last chance?" Before speaking, Pausch received a long standing ovation from a large crowd of over 400 colleagues and students. When he motioned them to sit down, saying, "Make me earn it," someone in the audience shouted back, "You did!"^[9][19]

During the lecture, Pausch was upbeat and humorous, alternating between wisecracks, insights on computer science and engineering education, advice on building multi-disciplinary collaborations, working in groups and interacting with other people, offering inspirational life lessons, and performing push-ups on stage. He also commented on the irony that the "Last Lecture" series had recently been renamed as "Journeys", saying, "I thought, damn, I finally nailed the venue and they renamed it."^[15] After Pausch finished his lecture, Steve Seabolt, on behalf of Electronic Arts—which is now collaborating with CMU in the development of Alice 3.0^[20]—pledged to honor Pausch by creating a memorial scholarship for women in computer science, in recognition of Pausch's support and mentoring of women in CS and engineering.^[9]

CMU president Jared Cohon spoke emotionally of Pausch's humanity and called his contributions to the university and to education "remarkable and stunning".^[21] He then announced that CMU will celebrate Pausch's impact on the world by building and naming after Pausch a raised pedestrian bridge^[22] to connect CMU's new Computer Science building and the Center for the Arts, symbolizing the way Pausch linked those two disciplines. Brown University professor Andries van Dam followed Pausch's last lecture with a tearful and impassioned speech praising him for his courage and leadership, calling him a role model.^[21][23][24]

The Randy Pausch Memorial Footbridge was dedicated on October 30, 2009, with Jai, Dylan, Logan and Chloe Pausch cutting the ribbon.

[edit] The Last Lecture

The Disney-owned publisher Hyperion paid $6.7 million for the rights to publish a book about Pausch called The Last Lecture, co-authored by Pausch and Wall Street Journal reporter Jeffrey Zaslow.^[25] The book became a New York Times best-seller on April 28, 2008.^[26] The Last Lecture expands on Pausch's speech. The book's first printing had 400,000 copies, and it has been translated into 46 languages. It has spent more than 85 weeks on The New York Times bestseller list, and there are now more than 4.5 million copies in print in the U.S. alone. Despite speculation that the book would be made into a movie, Pausch had denied these rumors, stating that "there's a reason to do the book, but if it's telling the story of the lecture in the medium of film, we already have that."^[27]

Media coverage[link]

Pausch was named "Person of the Week" on ABC's World News with Charles Gibson on September 21, 2007.^[28] His "Last Lecture" attracted wide attention from the international media,^[29] became an Internet hit, and was viewed over a million times in the first month after its delivery.^[30] On October 22, 2007, Pausch appeared on The Oprah Winfrey Show where he discussed his situation and summarized his "Last Lecture".^[18] On October 6, 2007, Pausch joined the Pittsburgh Steelers for the day during their regular practice, after the organization learned that one of his childhood dreams mentioned in his "Last Lecture" was to play in the NFL.^[31] On April 9, 2008, the ABC network aired an hour long Diane Sawyer feature on Pausch titled "The Last Lecture: A Love Story For Your Life".^[32][33] On July 29, 2008, ABC aired a follow up to the Last Lecture special, remembering Pausch and his famous lecture.^[34]

Other lectures and appearances[link]

Pausch gave a lecture about time management^[35] on November 27, 2007 at the University of Virginia, to an audience of over 850 people.^[36] In March 2008, Pausch appeared in a public service announcement video^[37] and testified before Congress in support of cancer research.^[38] On May 18, 2008, Pausch made a surprise return appearance at Carnegie Mellon, giving a speech at the commencement ceremony,^[39] as well as attending the School of Computer Science's diploma ceremony,^[40] and on May 19 Pausch appeared on the Good Morning America show.^[41] His lecture, "Really Achieving Your Childhood Dreams", was nominated at the 2007 YouTube Video Awards.^[42][43]

A devoted Star Trek fan, Pausch was invited by film director J. J. Abrams to film a role in Star Trek. Abrams heard of Pausch's condition and sent a personal e-mail inviting Pausch to the set. Pausch accepted and traveled to Los Angeles, California to shoot his scene. In addition to appearing in the film, he also has a line of dialogue at the beginning of the film ("Captain, we have visual.") and donated the $217.06 paycheck to charity.^[44][45]

Global interest in Boyle was triggered by the contrast between her powerful mezzo-soprano voice and her plain appearance on stage.^[6] The juxtaposition of the audience's first impression of her, with the standing ovation she received during and after her performance, led to an international media and Internet response. Within nine days of the audition, videos of Boyle—from the show, various interviews and her 1999 rendition of "Cry Me a River"—had been watched over 100 million times.^[7] Her audition video has been viewed on the internet several hundred million times.^[8] Despite the sustained media interest she later finished in second place in the final of the show behind dance troupe Diversity.

Boyle's debut album, I Dreamed a Dream (2009) remains as the UK best-selling debut album of all time, beating previous record holder, Spirit by Leona Lewis.^[9] I Dreamed a Dream is ranked fourth in its first week sales according to the Official Chart Company in the United Kingdom.^[9] In her first year of fame, Boyle made a fortune of £5 million with the release of I Dreamed a Dream and its lead off singles, "I Dreamed a Dream" and "Wild Horses".^[10] The success was continued with her second album, The Gift (2010), and was followed by Boyle's third album, Someone to Watch Over Me, released on 31 October 2011.^[11] On 12 May 2012, Susan returned to Britain's Got Talent to perform as a guest in the final singing "You'll See".^[12] The following day, she performed at Windsor Castle for the Queen's Diamond Jubilee Pageant singing "Mull of Kintyre".^[13] Boyle's net worth was estimated at £22 million in April 2012.^[14]
