Film(24Hz) to Video(USA/60Hz) transfer: adding 1 video FIELD (1/60 Sec) every 2 Film Image (@ 24 Image/s) on the following sequence: 2+1, 2, 2+1, 2 ..etc, that is 3,2,3,2..so it gives 5 Video Fields for 2 film Images (83.3 milliseconds). The lower redondancy is 4 films = 10 video because of the Odd/Even successive FIELD parity.
Film(25Hz) to Video transfer for "EUROPE/ASIA(50Hz): by simply running the Film telecinema 4% faster, it transfert 24 to 25 Images/s; so we have now 1 Film image(@ 25 Images/s) for 2 Video FIELDS (@ 1/50 Sec), that is also gives 1 Film for 1 FRAME video (@ 1/25 Sec) thus: 2 Films = 2 FRAMES Video (The resulting +4% audio pitch is quite negligible -less than 1/2 tone- for The quasi totality of applications.
A 2K image consists a computer format of 2048 x 1080 pixels. The aspect ratio is 17:9.
A 4K image consists a computer format of 4096 x 2160 pixels. The aspect ratio is 17:9.
8K image consists a computer format of 7680 x 4320 pixels. The aspect ratio is 17:9.
See Tri-Levels Sync.
System that minimizes visible artifacts contained in some animated images, by calculating new pixels or lines according to the motion of the picture.
Audio Engineering Society/European Broadcasting Union. This standard is a digital audio transfer.
In signal processing and related disciplines, aliasing refers to an effect that causes different signals to become indistinguishable (or aliases of tne another) when sampled. It also refers to the distortion or artifact that results when the signal reconstructed from samples is different from the original continuous signal.
Interface with a signal more powerful in output than in input. Allows several video or audio signals to be transmitted and distributed.
An analog signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity. It differs from a digital signal in terms of small fluctuations in the signal which are meaningful. Analog is usually thought of in an electrical context; however other systems may also convey analog signals. Standard audio and video signals are analog.
Pre-encoded enlarged DVD picture.
System which significantly eliminates video output flicker (see flicker).
Abnormal disruption of the image that looks like spots, cross color, scratch, steps effects, etc.
American Standard Code for Information Interchange. A standard code is used to exchange information between a device and a computer (i.e.: Keyboard). Analog Way uses ASCII code for its remote controls.
Ratio between a picture's width and height. The aspect ratio is mostly 4/3 for TV or 16/9 for HDTV. It still remains constant regardless of the screen size. There can also be specific sizes such as 5/3, 5/4, 8/5, 14/9, 15/9 or 16/10.
Describes a device such as a Scan Converter or Up/Down Converter that automatically recognizes any standard or specific format (resolution and synchronization) connected to its input.
A process which aligns the pixel clock to match with a source VGA signal, to allow for proper sampling of every pixel in the frame. This process is also sometimes called “PC Image Adjust”, “Centering”, etc.
The balanced (or differential) Audio system is made up of 3 conductors: the plus (+), minus (-) and ground. The + and - are of opposite phases so that it can drive a very long length of cable without any noise.
Range of frequencies that a signal can pass through a product without any distortion or loss of quality. The higher and wider the bandwidth, the better the resulting signal. The bandwidth is the difference between the highest and the lowest frequency of a signal, usually at -3dB of attenuation (0.7) from its maximum level.
Composite video signal, with a black picture used to synchronize (GENLOCK) certain video equipment together, therebyaligning the output. The signal is made up of vertical and horizontal sync. and Chroma burst information (1 wire).
This is the darkest level that an image can be. Usually, the adjustment of black level is set by the brightness control. The Black level is also the level of the video signal, which involves the blanking.
Part of a signal, being the interval between the end of one line or frame and the beginning of the following one. For example, it represents the turn off of a CRT display's beam (non visible) between 2 horizontal lines (horizontal blanking) or between 2 vertical frames or fields of a picture (vertical blanking). See Reduced Blanking.
Coaxial connector that can easily be locked. These connectors are widely used for video broadcast interconnections.
Amplified output to drive heavy loads or long coaxial cables.
Device that enables long distance signal driving. Can also provide several outputs (see Distribution Amplifier).
When the audio and video signals from the same source can be separated and used independently.
Intensity of the video level being the quantity of brightness emitted by the display (offset of a visible part of the video picture).
Electronic device with a unity gain, that allows an input signal to be "isolated" from the output signal.
