I am interested in Select An OptionCamera Link is a serial communication protocol standard [1] designed for camera interface applications based on the National Semiconductor interface Channel-link.

It was designed for the purpose of standardizing scientific and industrial video products including cameras, cables and frame grabbers. The standard is maintained and administered by the Automated Imaging Association or AIA, the global machine vision industry's trade group.

Camera Link uses one to three Channel-link transceiver chips with four links at 7 serial bits each. The data are serializedand the four data streams and a dedicated clock are driven over five LVDS pairs.

The camera link standard calls for these 28 bits to be transmitted over 4 serialized differential pairs with a serialization factor of 7.

The parallel data clock is transmitted with the data. To deserialize the data, a shift register and counter may be employed. The shift register catches each of the serialized bits, one at a time, then registers the data out into the parallel clock domain - once the data counter has reached its terminal value. Camera Link comes in several variants which differ in the amount of data that can be transferred.

Some of them require two cables for transmission. The "Full" configuration adds another bits to the data path, resulting in a bit wide video path [1] [2] [3] that can carry 5. Some camera and data acquisition hardware manufacturers have extended the bandwidth of the interface beyond the limits imposed by the Camera Link interface specification. A consensus has emerged in the industry about the bit variant, and compatible cameras and frame grabbers are marketed with the term "Camera Link Deca".

However, some manufacturers use the term "Extended Full" to refer to Deca configuration [4]and still others retain use of the term Camera Link Full while referring to Full Deca.

The bit video path can carry 6. The image below shows the relative signal timing of the clock and one data line of one of the Channel Link transceivers used for Camera Link transmissions.

Data words start in the middle of the high phase of the clock, and the most significant bit is transmitted first. The bits of pixel values are not assigned to serial transmitters in order, but are permutated in a complicated way, as shown in the following figure.

The figure labels the Camera Link data bits consecutively and includes 8 additional bits not part of the Camera Link Full specification. The Camera Link standard divides the data bits into eight 8-bit ports denoted by letter-number combinations, but uses the same letter-number combinations for color channels that do not always correspond one-to-one, making this notation ambiguous.

The upper half of this figure is only relevant for the Medium and Full configurations which require two physical interfaces and two cables.

The two rectangles in the middle represent the cables, with the connector pins of each signal printed at either side. The underscore represents an unused spare bit. It remains to be said how pixel data bits are assigned to the bits 0 to 71 used in the figure. For grey-scale pixels, this is a trivial one-to-one mapping; for colour pixels with a multiple of 8 bits per colour, the colours are simply concatenated in the order red, green and blue from LSB to MSB.Cost effective solution for camera evaluation and image quality testing during development phase.

CoaXPress is emerging as a smarter choice. CXP 1. High-speed CXP 2. In turn, the computer sends commands to apply the brake, turn, change lanes, or slow down, for example.

Full Automation Level 5where the passenger is travelling at highway speeds in real time with other vehicles on the road, will require significantly higher data rates than the GMSL2 interface can offer. Maximum speed for GMSL data transfer is 2.

This enables full resolution colour images to be captured by CXP megapixel cameras boasting xpx at 93fps. Multi-camera systems of varying resolutions, like those needed on self-driving cars, can be precisely synchronised with CXP 2. It can either continue down the path with GMSL and wait for it to catch up with the industry requirements through technological developments over several years, or embrace the much faster, easily integrated and proven CXP standard.

Along with being faster, CXP coaxial connectivity is a superior choice for a car's wiring harness.

High-Speed SerDes At 7nm

Besides the chassis and engine, wiring harnesses are the heaviest, most expensive component to a self-driving car. Cost savings from coaxial cables can be realised without trading off critical features such as accuracy, range, sampling rates, or overall system complexity. Market observers see cameras as an inexpensive compliment to LiDAR Light Detection and Ranging sensors, the established sensing technology for self-driving cars.

Unlike LiDAR, less costly cameras can read signs and see colours for safe navigation of roads. Cameras can also be mounted virtually anywhere on the car to cover a greater field of view, whereas LiDAR is typically set-up on the vehicle roof, a strategy that creates blind spots of low objects, especially in the rear of the car. Interference is another potential issue with LiDAR as these systems roll out more broadly.

LiDAR has also been faulted for using an exorbitant amount of power. Tesla's autopilot system currently uses video cameras and radar technology. New stereo cameras, which rely on two perspectives rather than one to establish depth, are posed to revolutionise autonomous car safety. Machine learning capabilities means a 3D camera equipped car can resolve objects better and react more quickly than human drivers.

This technology can also transform other modes of autonomous transportation such as trucks, tractors, ships, shuttle services, forklifts, trains and construction equipment.

New camera features high speed and performance.These standards are used for transmission of uncompressed, unencrypted digital video signals optionally including embedded audio and time code within television facilities; they can also be used for packetized data. Fiber optic variants of the specification such as M allow for long-distance transmission limited only by maximum fiber length or repeaters.

SDI and HD-SDI are usually available only in professional video equipment because various licensing agreements restrict the use of unencrypted digital interfaces, such as SDI, prohibiting their use in consumer equipment. There are various mod kits for existing DVD players and other devices, which allow a user to add a serial digital interface to these devices.

The various serial digital interface standards all use one or more coaxial cables with BNC connectorswith a nominal impedance of 75 ohms.

This is the same type of cable used in analog video setups, which potentially makes for easier upgrades though higher quality cables may be necessary for long runs at the higher bitrates. Uncompressed digital component signals are transmitted.

Data is encoded in NRZI format, and a linear feedback shift register is used to scramble the data to reduce the likelihood that long strings of zeroes or ones will be present on the interface. The interface is self-synchronizing and self-clocking. Framing is done by detection of a special synchronization pattern, which appears on the unscrambled serial digital signal to be a sequence of ten ones followed by twenty zeroes twenty ones followed by forty zeroes in HD ; this bit pattern is not legal anywhere else within the data payload.

In addition to optical specification, ST also mandates laser safety testing and that all optical interfaces are labelled to indicate safety compliance, application and interoperability. In SD and ED applications, the serial data format is defined to 10 bits wide, whereas in HD applications, it is 20 bits wide, divided into two parallel bit datastreams known as Y and C. The SD datastream is arranged like this:.

For all serial digital interfaces excluding the obsolete composite encodingsthe native color encoding is YCbCr format. The luminance channel Y is encoded at full bandwidth The Y, Cr, and Cb samples are co-sited acquired at the same instance in timeand the Y' sample is acquired at the time halfway between two adjacent Y samples. In the above, Y refers to luminance samples, and C to chrominance samples. Cr and Cb further refer to the red and blue "color difference" channels; see Component Video for more information.

This section only discusses the native color encoding of SDI; other color encodings are possible by treating the interface as a generic bit data channel. The use of other colorimetry encodings, and the conversion to and from RGB colorspace, is discussed below.

Video payload as well as ancillary data payload may use any bit word in the range 4 to 1, 16 to 3FB 16 inclusive; the values 0—3 and 1,—1, 3FC 16 —3FF 16 are reserved and may not appear anywhere in the payload. These reserved words have two purposes; they are used both for Synchronization packets and for Ancillary data headers.

A synchronization packet commonly known as the timing reference signal or TRS occurs immediately before the first active sample on every line, and immediately after the last active sample and before the start of the horizontal blanking region.

The synchronization packet consists of four bit words, the first three words are always the same—0x3FF, 0, 0; the fourth consists of 3 flag bits, along with an error correcting code.

As a result, there are 8 different synchronization packets possible. Some delay between the two cables in a dual link interface is permissible; equipment which supports dual link is expected to buffer the leading link in order to allow the other link to catch up.

In SD-SDI and enhanced definition interfaces, there is only one datastream, and thus only one synchronization packet at a time. Other than the issue of how many packets appear, their format is the same in all versions of the serial-digital interface.YOU are responsible for independently confirming the validity of information through other sources.

The worst-case predictions regarding the effects of global warming are the most likely to be true, a new study published this week has warned. Ken Caldeira, an atmospheric scientist at the Carnegie Institution for Science, who co-authored the study told The Independent.

Since the Earth's climate system is incredibly complex, different scientists have put forward different models to determine how fast the planet is warming. This has resulted in a range of predictions, some more dire than others. The new study, published in the academic journal "Nature", aimed to determine whether the upper or lower-end estimates are more reliable.

Caldeira and co-author Dr. Patrick Brown looked at models that proved to be the best at simulating climate patterns in the recent past. They reasoned that these models would present the most accurate estimates. According to the researchers' conclusions, models with higher estimates are more likely to be accurate, meaning the degree of warming is likely 0.

Scientist that weren't involved with the research have come out in support of the findings as well.

Professor Collins explained that the new study "breaks the issue down into the fundamental building blocks of climate change. President Donald Trump have dismissed such claims. However, with more and more research backing worst-case predictions, complete dismissal of such findings becomes increasingly difficult. This study in particular addresses one key point climate change deniers often seize upon: the uncertainty that comes with so many different climate models. RELATED: Climate disaster map shows Georgia as second most apocalyptic state"This study undermines that logic," Dr.

Brown told MIT Technology Review. Cadeira's study also comes on the heels of a dire warning issued by more than 15,000 scientists from around the world last month. The scientists warned that quick and drastic actions should be undertaken by society to address the threat to Earth.

President Donald Trump said in June that he would pull the U.
