A frame synchronizer is a device used in live television production to match the timing of an incoming video source to the timing of an existing video system.

The frame synchronizer essentially takes a picture of each frame of incoming video and then immediately outputs it with the correct synchronization signals to match an existing video system.

In telemetry applications, a frame synchronizer is used to frame align a serial pulse code modulated ( PCM ) binary stream.

The frame synchronizer immediately follows the bit synchronizer in most telemetry applications.

Controlled by a computer, the synchronizer can dictate the timing of each frame of the CCD camera's sequence in conjunction with the firing of the laser to within 1 ns precision.

The signals which cannot be synchronized ( either because they originate outside the facility or because the particular equipment doesn ’ t accept external sync ) must go through a frame synchronizer.

With Earth held stationary at the center of a nonrotating frame, the successive inferior conjunction s of Venus over eight Earth years trace a pentagram mic pattern ( reflecting the difference between the numbers in the ratio ).

The flag is used to perform high-level data link synchronization which indicates the beginning and end of the frame with the unique pattern 01111110.

To ensure that the 01111110 pattern does not appear somewhere inside the frame, bit stuffing and destuffing procedures are used.

The frame syncronisation pattern is a known binary pattern which repeats at a regular interval within the PCM stream.

Typically the frame sync pattern is followed by a counter ( Sub-Frame ID ) which dictates which minor or sub frame in the series is being transmitted.

A sync-word is a pattern that is placed in the data stream through equal intervals ( that is, in each frame ).

The elements of the seal are contained within the pattern formed by the outer frame of a hawser rope or cable, and the inner frame of an anchor chain, of a type employed in ships of the Colonial era.

She seems to be invisible to the men as she crawls across the table, uninhibited ; her body continues seamlessly again onto a new frame, crawling through foliage ; following the flowing pattern of water on rocks ; following a man across a farm, to a sick man in bed, through a series of doors, and finally popping up outside on a cliff.

Although there is no constant frame, style, or plot, Rumi generally follows a certain writing pattern that flows in the following order:

Lake volume is now at the mercy of a cascade of forces that include the fact that it is very likely impossible that the prevailing climate pattern of profound drought will or can change to precipitation surcharge in a time frame shorter than that in which the lake level will fall below the dead storage level of the downstream diversion and hydro-power intake tunnels.

For Parsons, it is a set of social institutions regulating pattern of action-orientations, which again are based on a frame of cultural values.

* The ominous " Poetry Girl " appears in a frame with a pattern very similar to that of Test Card F in the 2010 Doctor Who episode, " The Beast Below ".

While there are slight variations, the main bulk of its buildings follow a similar theme with a complex geometrical design featuring a mix of zinc, perforated zinc, glass and sandstone tiles over a metal exoskeletal frame in a complex geometrical pattern composed entirely of scalene triangles.

In architecture and structural engineering, a space frame or space structure is a truss-like, lightweight rigid structure constructed from interlocking struts in a geometric pattern.

** Frame: The most familiar overo pattern, the gene for frame has been genetically mapped and in the homozygous form, results in Lethal White Syndrome ( LWS ).

Also called Overo Lethal White Syndrome ( OLWS ) or, less often, White Foal Syndrome ( WFS ), it is linked to a recessive gene associated with the frame overo pattern.

LWS is also not unique to Paint Horses ; it can occur in any equine breed where the frame overo coat pattern is found.

If 24p footage cannot be sped up, ( for example if it were coming through a live NTSC or HD feed ) it instead can be converted in a pattern where most frames were held on screen for two fields, but every half second a frame would be held for three fields.

This pulldown pattern is used to avoid segmenting a 24p frame into two different 60i fields that exist in two different 60i frames.

Molding or moulding ( see spelling differences ) is the process of manufacturing by shaping pliable raw material using a rigid frame or model called a pattern.

Horses that are heterozygous for the gene that causes lethal white syndrome often exhibit a spotted coat color pattern commonly known as " frame " or " frame overo.

Calculations are performed on these objects, as opposed to a range of cells, so adding two time series automatically aligns them in calendar time, or in a user-defined time frame.

From the CMB data it is seen that our local group of galaxies ( the galactic cluster that includes the Solar System's Milky Way Galaxy ) appears to be moving at 627 ± 22 km / s relative to the reference frame of the CMB ( also called the CMB rest frame, or the frame of reference in which there is no motion through the CMB ) in the direction of galactic longitude l

( Often codecs create segments called a " frame " to create discrete data segments for encoding and decoding.

Because interframe compression copies data from one frame to another, if the original frame is simply cut out ( or lost in transmission ), the following frames cannot be reconstructed properly.

Another difference between intraframe and interframe compression is that with intraframe systems, each frame uses a similar amount of data.

Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted.

A data packet on the wire is called a frame.

The middle section of the frame consists of payload data including any headers for other protocols ( e. g., Internet Protocol ) carried in the frame.

The frame ends with a 32-bit cyclic redundancy check, which is used to detect corruption of data in transit.

Note that due to the reduced number of colors in the image, there are obvious display issues. GIF is palette-based: the colors used in an image ( a frame ) in the file have their RGB values defined in a palette table that can hold up to 256 entries, and the data for the image refer to the colors by their indexes ( 0 – 255 ) in the palette table.

Within each frame the LZW-coded image data is arranged in sub-blocks of up to 255 bytes ; the size of each sub-block is declared by the byte that precedes it.

92BA: 00-end of LZW data for this frame

Some economy of data is possible where a frame need only rewrite a portion of the pixels of the display, because the Image Descriptor can define a smaller rectangle to be rescanned instead of the whole image.

The 802. 11a standard uses the same data link layer protocol and frame format as the original standard, but an OFDM based air interface ( physical layer ).

* 802. 3 ( raw ) is used in legacy systems and involves IPX data starting immediately after 802. 3 frame header.

The packet starts with the destination ethernet address ( 6 bytes ), source ethernet address ( 6 bytes ), and frame length ( 2 bytes ) followed by two bytes 0xFF 0xFF then the IPX data.

* 802. 2 ( Novell ) comprises 802. 3 frame header ( destination, source, length ) followed by LLC header ( 3 bytes-0xE0, 0xE0, 0x03 ) followed by IPX data.

* 802. 2 ( SNAP ) comprises 802. 3 frame header, LLC header ( 3 bytes-0xAA, 0xAA, 0x03 ), SNAP header ( 5 bytes-0x00, 0x00, 0x00, 0x81, 0x37 ) and IPX data.

* Ethernet II comprise an Ethernet II frame header ( Destination, Source, EtherType ) followed by IPX data.

In video compression, a keyframe, also known as an Intra Frame, is a frame in which a complete image is stored in the data stream.
