It would eventually be replaced by cheaper systems using video compression, most notably Sony's Digital Betacam ( still heavily used as a electronic field production ( EFP ) recording format by professional television producers ) that were introduced into the network's television studios.

If an interlaced video has a frame rate of 15 frames per second the field rate is 30 fields per second.

* In 2000, a new video display from Daktronics, measuring high by wide, was added in center field.

* Before the 2011 season, three new scoreboards beyond right-center field were installed: a 38-by-100-foot scoreboard in right-center field, a 17-by-100-foot video screen in center field, a 16-by-30-foot video board in right field, along with a new video control room.

This subsystem consisted of 4 parts, a Cassegrain telescope with a 1. 05 ° by 1. 05 ° field of view, a shutter and red / green filter assembly with 0. 08s and 0. 20s exposure times, a slow scan vidicon tube which translated the optical image into an electrical video signal, and the electronic systems required to convert the analogue signal into a digital bitstream for transmission.

The video starts at 25x, about 6 mm across the whole field of view, and zooms in to 12000x, about 12 μm across the whole field of view.

In the field of video and audio engineering:

The VITC code is always repeated on two adjacent video lines, one in each field.

* 50i is an interlaced format and is the standard video field rate per second for PAL and SECAM television.

* 60i is an interlaced format and is the standard video field rate per second for NTSC television ( e. g. in the US ), whether from a broadcast signal, DVD, or home camcorder.

As with its photographs, UPI thereby lost all control of its newsfilm and video library, which is now held by WTN-successor Associated Press Television News, which entered the video news field long after UPI left it.

* In the video game Portal, yet another similar gun to Half-Life 2 < nowiki >'</ nowiki > s, which is titled the " Aperture Science Handheld Portal Device ", can create a weaker zero-point energy field by simply lifting objects and carrying them, but cannot throw or pull in from a distance.

Normalization, which is reversed when 1 is being added above, can be thought of as a form of compression ; it allows a binary significand to be compressed into a field one bit shorter than the maximum precision, at the expense of extra processing.

In a tokamak system this compression is achieved simply by moving the plasma into a region of higher magnetic field ( i. e., radially inward ).

* Dysfunction: depending on the tumor location and the damage it may have caused to surrounding brain structures, either through compression or infiltration, any type of focal neurologic symptoms may occur, such as cognitive and behavioral impairment ( including impaired judgment, memory loss, lack of recognition, spatial orientation disorders ), personality or emotional changes, hemiparesis, hypoesthesia, aphasia, ataxia, visual field impairment, impaired sense of smell, impaired hearing, facial paralysis, double vision, dizziness, but more severe symptoms might occur too such as: paralysis on one side of the body hemiplegia or impairment to swallow.

A bilateral temporal visual field defect ( bitemporal hemianopia — due to compression of the optic chiasm ), often associated with endocrine dysfunction — either hypopituitarism or hyperproduction of pituitary hormones and hyperprolactinemia is suggestive of a pituitary tumor.

In the field of data compression, Shannon – Fano coding, named after Claude Shannon and Robert Fano, is a technique for constructing a prefix code based on a set of symbols and their probabilities ( estimated or measured ).

Non-uniform stretching or compression of the receptor distribution could explain the field dependency of the macrospia.

If the compression forces were closer to the fovea the resulting compression would cause a greater amount of macropsia at lower field angles with little effect at higher field angles where the receptor distribution is not as compressed.

The compression process allows the chemical energy of the explosives to be ( partially ) transformed into the energy of an intense magnetic field surrounded by a correspondingly large electric current.

3: Magnetic field lines after compression.

By adding together the external magnetic field and the induced field, the final configuration after compression can be obtained ; the total magnetic flux through the ring has been conserved ( even though the distribution of the magnetic flux has been modified ), and a current has been created in the conductive ring.

Perspective distortion takes two forms: extension distortion and compression distortion, also called wide-angle distortion and long-lens or telephoto distortion, when talking about images with the same field size.

M71 was long thought ( until the 1970s ) to be a densely packed open cluster and was classified as such by leading astronomers in the field of star cluster research due to its lacking a dense central compression, and its stars having more " metals " than is usual for an ancient globular cluster ; furthermore, it's lacking the RR Lyrae " cluster " variable stars that are common in most globulars.

Other manifestations will include weakness of the extremities on the opposite side as the lesion ( except in rare cases ), due to compression of the crossed pyramid pathways, and a loss of visual field opposite to the side of the lesion, due to compression of the posterior cerebral artery on the side of the lesion.

Some of the aspects of video that most videophiles are concerned with include frame rate, field frequency, color system, resolution, compression artifacts, motion artifacts, video noise, screen size, etc.

Here, the Doctor realises that they have materialised inside the compression field of a Miniscope, a machine that keeps miniaturised groups of creatures in miniaturised versions of their natural environments.

Time Reversal, specifically in the field of acoustics, is a process by which the linearity of sound waves is used to reverse a received signal ; this signal is then re-emitted and a temporal compression occurs, resulting in a reverse of the initial excitation waveform being played at the initial source.

Such a tidal field is characterized by tension in one direction and compression in the orthogonal directions ; the eigenvalues have the pattern (- 2, 1, 1 ).

Likewise, the angular momentum can be measured from far away using frame dragging by the gravitomagnetic field.

One set of odd or even lines is referred to as a " field ", and a consecutive pairing of two fields of opposite parity is called a frame.

An Ethertype field in each frame is used by the operating system on the receiving station to select the appropriate protocol module ( i. e. the Internet protocol module ).

* Even when there is no external magnetic field, in the inertial frame of the moving electron, the electromagnetic field of the nucleus has a magnetic component.

Today the notion of " absolute space " is abandoned, and an inertial frame in the field of classical mechanics is defined as:

IEEE 802. 3 is an exception ; Ethernet originally used Ethernet II framing, with a 2-octet type field containing an EtherType value, and no 802. 2 header, but the original IEEE 802. 3 specification used a framing wherein the 2-octet field following the 6-octet destination and source MAC addresses contained a frame length, with an 802. 2 LLC header following the length field.

The format of a PDU frame is identified by the lower two bits of the first byte of the control field.

b ) a co-rotation field, which is generated in a co-rotating frame of reference in order to compensate for the Lorentz force.

The standard recommended a frame rate of 30 frames ( images ) per second, consisting of two interlaced fields per frame at 262. 5 lines per field and 60 fields per second.

It used a rotating color wheel, reduced the number of scan lines from 525 to 405, and increased the field rate from 60 to 144, but had an effective frame rate of only 24 frames per second.

* Priority Code Point, a three-bit priority field within an Ethernet frame header when using IEEE 802. 1q tagged frames.

With just 54 seconds left in the half, Franklin attempted a 28-yard field goal, but Raiders linebacker Ted Hendricks extended his 6 ' 7 " frame at the line and blocked the kick.

The externally-generated field is usually that produced by a perturbing third body, often the Sun or the Moon in the frequent example-cases of points on or above the Earth's surface in a geocentric reference frame.

Frame-relay frame structure essentially mirrors almost exactly that defined for LAP-D. Traffic analysis can distinguish Frame Relay format from LAP-D by its lack of a control field.

That is, the electric and magnetic fields are not completely separate phenomena ; what one observer perceives as an electric field, another observer in a different frame of reference perceives as a mixture of electric and magnetic fields.

Film and Television companies use this rate in 50 Hz regions for direct compatibility with television field and frame rates.

Link-level functions include ( a ) transmit bit injection and receive bit extraction, ( b ) address and control field interpretation, ( c ) command response generation, transmission and interpretation, and ( d ) frame check sequence computation and interpretation.

There is no contradiction because the electric field in the rest frame differs from the E-field in the lab frame: E ' = E + v × B.

Ferrous materials aligned with the Earth's magnetic field that are subject to vibration ( e. g., frame of a conveyor ) have been shown to acquire significant residual magnetism.
