Video Processing Subsystem: Vivado, Adaptive Deinterlacing, Scaling, Color Space Conversion, Chroma Resampling

Creating a Video Processing Subsystem in Vivado

In this demo we will use Vivado to create a video processing subsystem. The ISP IP takes RAW AXI4-Stream input and outputs a 24-bit, 8 bits per pixel (8 bpc) RGB output image transported via AXI4-Stream.

The adapter, monitor and monitor cable are each modified so that the monitor identification pins can be reused to provide an electrical path for a dynamic communications link between the adapter and the monitor.

Adaptive deinterlacing

Deinterlacing is necessary to convert interlaced video to high quality progressive scan data. Without it, a viewer may notice a visible “combing” of alternate lines when moving objects are displayed on a progressively scanned display. High quality deinterlacers eliminate these artifacts to ensure smooth image movement.

The goal of deinterlacing is to produce a single output frame at the same rate as the original sequence of input fields. This is accomplished using a combination of field combining (weaving or blending) and frame extension techniques (bob or line doubling).

These methods work well in scenes with little or no motion, but can introduce noticeable artifacts when the image is moving. More advanced deinterlacing technologies, like that implemented in Digital Rapids’ capture and preprocessing hardware, Flux, use motion adaptive deinterlacing. This technique compares pixels between the current and previous fields to determine whether there is a significant change in position. Areas with no motion are statically meshed, while areas with motion are treated with a proprietary filtering technique that results in superior image quality.


The video processing subsystem is a collection of hardware processors that implement essential image processing algorithm steps. It also includes a centralized buffer scheme that provides an efficient interface between processing modules and reduces memory bandwidth requirements. This enables the device to process more data in real time without increasing the number of on-chip memory resources.

This example uses the Zynq UltraScale+ MPSoC and demonstrates a fully configurable video processing pipeline handling resolutions up to 4K. It features motion adaptive deinterlacing, scaler, color space conversion, and chroma resampling.

The video processing subsystem can be used to create matrix switchers, which are commonly utilized in commercial and residential environments. These devices can scale multiple inputs to one or more displays and may support audio like digital coax, SPDIF, and analog RCA. They can also control the output resolution of a display. A common application is a sports bar, where visual imagery can make an impact.

Color space conversion

Color space conversion involves converting the representation of a color from one format to another. This can be done using software or dedicated hardware. The latter uses circuits to perform the conversions and provides high performance, efficiency, and accuracy.

Color spaces are mathematical models that describe colors independently of the specific device that captures and displays them. They also provide a means for representing and transmitting these colors over long distances. However, there are some limitations to these color models that can affect the quality of image processing.

Color space conversion is a complex process that can result in loss of information or inconsistencies across devices. It is important to choose the appropriate color space for an application. There are several different methods available for color space conversion, including resampling and perceptual rendering. Several software tools are available to help with the process.

Chroma resampling

Chroma subsampling reduces the bandwidth required to transmit color information by limiting the amount of color detail in a video or image signal. It’s a visually lossless form of compression that allows native R, G, B data to be transmitted at higher resolutions or refresh rates than might otherwise be possible, and it can also help reduce the overall file size of images and videos.

Most modern digital video formats use a 4:2:2 chroma sampling configuration. This requires that every two pixels in the top “a” row of pixels share a color sample, and that each bottom pixel shares no chroma samples at all. This is fine for most applications but can be a limitation when dealing with green screen work, visual effects, and serious color grading. The VPSS supports three different chroma resampling algorithms; nearest neighbor, bilinear, and filtered. The VPSS’s bilinear resampling offers a good compromise between visual image quality and device resource cost.

Choosing the Right Video Card for Your Computer

Which Video Card Do I Need?

Articles are a great way to engage your audience and inspire interactions with them. They can take many forms, from how-to templates to industry news pieces.

While AMD has improved, NVIDIA is still the leading brand for high-powered GPUs. Their RTX series offers real-time ray tracing, while the older GTX cards offer excellent performance for 4K editing.

What is a graphics card?

A graphics card is a component that allows your computer to display graphical data. It is also known as a video card, display adapter, or graphics accelerator card.

The graphics card converts information that the CPU sends into pixels – tiny squares of color that combine to make images on your screen. The more pixels there are, the higher the definition of the image.

Graphics cards also help speed up 2D and 3D rendering in programs like web browsers, photo editors, CAD, and video games. You can check what kind of graphics card your system has by opening the System Information app and looking at Components > Graphics Card.

Most graphics cards have their own dedicated memory, called video RAM (VRAM). The more VRAM your GPU has, the better it will perform. Most cards have one of several connection ports that connect it to your monitor, including HDMI and DisplayPort. Higher-end cards can also support the more advanced DisplayPort 1.3 standard, which is used on many flat panel displays.

What are the different types of graphics cards?

There are many different types of graphics cards on the market, and it can be hard to keep up with all of the specifications. To make an informed purchase, it’s important to understand the specifications that matter.

First and foremost, you’ll want to consider the GPU’s power requirements. Most dedicated GPUs require more than the standard 75 Watts a PCIe slot provides, so you’ll need to ensure your power supply can support it.

Also, look at the amount of memory the card has. This can vary between 2GB all the way up to 24GB for Nvidia’s flagship GeForce RTX 3090. The more VRAM a GPU has, the better it performs.

Another specification that matters is the type of display it supports. Some cards support AMD’s FreeSync or Nvidia’s G-Sync technologies, which synchronize the frame rate of your GPU with your monitor’s refresh rate to eliminate screen tearing and reduce motion blur. Finally, look at the physical dimensions of a GPU to ensure it will fit in your case.

How do I know which graphics card I need?

If you’re looking to upgrade the graphics in your PC, knowing which GPU is right for you can be a challenge. First, you need to consider what games you plan to play and the resolution and refresh rate of your monitor. Different types of games have different requirements, with first-person shooters having some of the highest demands and real-time strategy games having the lowest.

Next, you need to determine your budget and performance requirements. You also need to make sure that your power supply can provide enough wattage for the GPU you’re considering.

Finally, you need to choose a graphics card that matches your case and motherboard. Graphics cards come in a variety of lengths, and you’ll want to make sure that it fits comfortably inside your case without interfering with other components such as cabling or storage bays. Additionally, some graphics cards require two slots worth of width, while others only require one slot.

Which graphics card should I buy?

There are many factors to consider when choosing a graphics card, and there is no one-size-fits-all solution. However, there are a few tips that can help you narrow down your options and find the perfect card for your needs.

First, identify your gaming goals. Different types of games have different demands, with first-person shooters having the highest requirements while real-time strategy games tend to require lower ones.

Another consideration is the amount of VRAM required by your games. For example, games like Cyberpunk 2077 require 12GB of VRAM to run at full performance. Choosing a higher-end GPU with more VRAM can future-proof your system and allow for greater detail settings in newer games.

Also, keep in mind that modern graphics cards can consume a lot of power and may require supplemental PCIe power connectors (typically in 6- or 8-pin varieties). Make sure your power supply is capable of handling these requirements before purchasing a card.

Exploring Video Processing and its Applications

What is Video Processing?

Video processing converts analog or digital signals into a format that can be displayed on the screen. It may also be compressed and multiplexed with other streams for storage or transmission over a communication channel.

Backend video processing includes features like noise reduction, deinterlacing and resolution scaling. It may also perform frame rate conversion and color space conversion.

Image processing

Image processing is a subset of video processing and can include methods for changing the characteristics of an image or improving its quality. This is a broad field that encompasses methods such as deblocking, noise reduction, and color space conversion.

The goal of image/video processing is to improve the overall picture quality, or reduce its storage and transmission requirements. This can be accomplished by using various techniques such as video encoding, frame rate adjustment, deinterlacing, and video editing.

For example, interpolation techniques may be used to create a smoother video image by combining the best elements of each individual frame. In addition, video filters are used to perform basic video manipulations such as image resizing and brightness/contrast control. More advanced image/video processing algorithms use statistical analysis to identify data insights or support automated tasks in computer vision use cases. These techniques can help organizations streamline tedious tasks and make informed decisions. They can also enable new social media applications that allow users to share visual content in a way that is both attractive and engaging.

Video signal processing

Video processing involves using software and hardware to edit the images and sound recorded in video files. These algorithms can be very simple, as in adjusting the brightness or contrast of an image, or they can be much more complex, such as in tracking objects that move throughout video sequences.

These algorithms can also be applied to the audio tracks of videos, such as adjusting the volume during overlaps or adding background music. This type of video processing is also used to improve video quality, add visual effects, and encode and compress videos for playback on mobile devices or the Web.

Video processing is a broad term that refers to any application of computer algorithms to digital video. It might include prefilters like contrast changes, deflicking, or noise elimination; intrafilters such as pixel size conversions; and output filters.

Video encoding

Video encoding is a type of video processing that converts RAW video content into compressed digital data for transmission over the internet. This is a key step in optimizing videos for the web, ensuring compatibility with different devices and platforms.

Video encoders use a combination of algorithms to reduce the size of video files without compromising quality. For example, they might pixelate video frames or compress them using YCbCr color compression. They might also apply prefilters to remove aliasing or artifacts from images.

The encoding process takes place prior to uploading video files onto a streaming service, such as Uploadcare. It’s an important step that optimizes the videos for streaming, reducing file sizes and ensuring quality for the broadest possible audience.

Video editing

Video editing is a type of image processing wherein the video clips are arranged in a timeline, music tracks are added, digital on-screen graphics and effects can be applied and then the final program is “rendered” as a movie. Then, it can be saved as a file to be played on a computer or on other devices like mobile phones.

Video processing includes post filters like deinterlacing, which eliminates the feathering artifacts that can appear when a video recorder interlaces the images it records. Other post processing includes video conversion, where film is converted to video.

Other examples of video processing include upconversion, resolution scaling, enhancement, frame rate conversion, color space conversion and brightness/contrast/gamma adjustment. In some cases backend video processing is used to convert 2-D video to 3-D and vice versa. This involves a matrix or multiplexer that can switch between different camera views and cycle them through a monitor. This can be done with the legacy products of a cross-point matrix or multiplexer.

S-Video: An Analog Video Connector for Old Devices

What is S-Video?

S-video is an analog video connector used on older computers, TVs, DVD players and VCRs. It separates the luminance (brightness) and chroma (color) signals and provides synchronization pulses.

While S-video isn’t as good as newer digital interfaces like HDMI, it’s a useful connection for old devices. You can use an adapter to convert S-video to an HDMI signal.

What is S-Video?

S-video is an analog color video cable and signal format. It is superior to composite video cables and signals, but not as good as component video.

S-Video carries the luminance (black-and-white) and chrominance (color) signals on separate wires, with ground and horizontal and vertical sync pulses. This is in contrast to RCA, which mixes the luminance and chrominance signals together on one cable. S-Video also provides a higher bandwidth for the luminance signal than does composite.

The S-video connector consists of a 4-pin mini-DIN plug that fits into a matching port on the device. It is important to check that the port and plug match; it is easy to damage an S-video plug by inserting it in a non-compatible port or by pushing too hard when removing it.

Some older TVs, VCRs and game consoles only have S-video inputs. You can use an adapter cable to convert from an S-video to a standard RCA cable.

How to Connect

S-video cables separate brightness and color information into two distinct signals. The resulting video signal is of higher quality than composite and earlier analog color-video standards. To connect your device to an S-video cable, first examine both the S-video port on your device and the connector on each end of the cable. Both the port and the connector must have the same number of holes to be compatible. S-video connections are round and can have either 4-pin or 7-pin holes clustered around the center.

S-video ports are the same size as RCA audio jacks and can be used to transmit both video and audio. If your television does not have an S-video port, you can use an inexpensive s-video to HDMI converter to convert the video to an HDMI signal, which can be connected to your TV. Avoid connecting and disconnecting your devices frequently, which can cause premature wear and tear to the s-video connection.

Buying a S-Video Cable

S-video isn’t very common on modern digital devices but you can still find it in older equipment. It’s an excellent choice for connecting an old game console or video camera to a TV or monitor and offers better colors and clarity than standard composite.

S-Video connectors are round with four or seven pins, depending on the device. The pins fit in one way only – try to plug the cable gently, as pushing too hard can damage the small pins inside.

Markertek stocks a selection of S-Video cables in all different sizes. Choose the length that matches your needs. Look for cables with a high shielding percentage, which will help to reduce interference from electromagnetic and radio waves caused by appliances in the vicinity. This is especially important if the cable runs long distances or around other electrical equipment. It’s also worth noting that a S-Video cable can transfer only video information – the separate channels for brightness and color signals must be converted to an analog signal by the equipment receiving the signal.

Getting Started

Unlike composite video, s-video separates brightness and color information into two separate signals. This reduces signal interference and improves resolution. It also allows for a higher number of colors, which provides more vibrant images.

If you want to upgrade your older device to support s-video, make sure you have the proper cables. You’ll need a cable with an RCA type connector that matches the one on your device. The cable should have 4 pins inside: 2 are grounds and the other two carry luma (brightness) and chroma.

If you can’t afford to buy a new s-video device, you can use a hack to combine the chroma and luma signals. However, this can be rather tricky and may not yield optimal results. Mike is working on a YC core for MiSTer that will hopefully make this process much easier.

Exploring K-Chips: Integrated Circuits that Enhance Performance

What is a K-Chim?

A k-chip is an integrated circuit that combines various components in a single package. This allows the chip to perform many functions simultaneously and more efficiently.

Intel processors with a “K” at the end of their name are unlocked and allow you to change their multiplier (provided your motherboard is capable, like a z series board). These models also lack integrated graphics.


The processors in computers are a crucial component to any PC build. They are the brains that translate the input from your mouse and keyboard into digital commands for the rest of your hardware to interpret.

If you’re looking to upgrade your current CPU, you may notice that some models have a “K” or “KF” at the end of their name. These designations indicate whether the processor can be overclocked, which can boost their base clock speeds.

The “K” designation signifies that the Intel processor can be altered in order to increase its speed. The process of doing so involves adjusting the CPU’s multiplier, which can be done by changing the bios settings on a compatible motherboard. However, the K series processors do not have integrated graphics. This might be a problem if you’re worried that your graphics card could die at any time, leaving you without a way to feed your monitor those gorgeous game frames.


Motherboards are the part of a computer that houses a CPU and connects it to memory, expansion cards and other hardware. The motherboard also contains the chipset, which relays information between the CPU and RAM. Modern motherboards use dual-channel memory architecture – two channels for transferring data between the CPU and RAM.

Intel offers several different processors and motherboards to meet the needs of different customers, including the budget-oriented B series and the performance-oriented Z series. While it is possible to use a K-series CPU on a B-series motherboard, this may limit the performance of the system.

In general, a K-series CPU will allow you to adjust the multiplier in the BIOS (provided that the motherboard is capable of overclocking). This allows for increased clock speed which can lead to improved performance. However, the K series does not come with a standard cooler and may require an additional one. Additionally, the K series does not have integrated graphics so it will need a dedicated graphics card to function.

Graphics Cards

Graphics cards, also known as video cards or display adapters, are installed in most computer systems to process graphical data for high quality displays. They are designed to provide excellent color, clarity and definition.

In addition to accelerating real-time 3D graphics applications, GPUs are now used in many other computer tasks. Recent examples include accelerated video decoding using DxVA (for Windows), VDPAU, VAAPI and XvMC (for Linux-based and UNIX-like operating systems).

Discrete GPUs are mounted on a separate circuit board from the motherboard and require their own power supply. This can add to the overall cost of a computer, but can deliver significant performance improvements. GPUs also create a lot of heat that must be dissipated, so they are often designed with built in fans to keep them cool.


Memory is the faculty of the human mind by which we encode, store, and retrieve past experiences. Cognitive neuroscientists divide memory into declarative and procedural components. The former involves the expression of memory at the behavioral or conscious level, while the latter occurs at a physiological level as neural changes known as engrams.

The memory used with k-chip is a double data rate 4 synchronous dynamic random access memory (SDRAM). This type of RAM offers higher performance than older DRAMs and enables multiprocessor systems to run more applications simultaneously.

An RRAM-CIM core consists of a TNSA, drivers for BLs, WLs and SLs, registers that store MVM inputs and outputs, and an LFSR pseudo-random number generator. It also has three operating modes: a weight-programming mode, a neuron-testing mode and an MVM mode. Various hardware-algorithm co-optimization techniques mitigate the impact of device and circuit non-idealities on inference accuracy. Various hardware-measured inference results for various AI benchmarks are shown.

Exploring ChIP-seq: Mapping Protein-DNA Interactions


Chromatin immunoprecipitation sequencing, also known as ChIP-seq, is a powerful technique for mapping protein-DNA interactions. This information is essential for understanding how genes are regulated by transcription factors and other proteins.

However, little is known about the differences between ChIP-chip and ChIP-seq data sets. In particular, it is unclear whether the average signal profiles constructed by these two technologies differ significantly.

What is ChIP-seq?

ChIP-seq, or chromatin immunoprecipitation sequencing, is a powerful tool for identifying genome-wide binding sites of proteins. It combines Chromatin IP (ChIP) assays with next-generation sequencing to identify DNA sequences that are bound by specific proteins, such as transcription factors. This method has been used to study how genes are regulated during cell development and disease progression.

In a ChIP experiment, chromatin is reversibly crosslinked with an agent such as mild formaldehyde. The chromatin is then sheared to fragments that are a few hundred to several thousand base pairs in length. This step is necessary to make DNA binding interactions accessible to antibody reagents. The chromatin is then usually either sonicated or digested with micrococcal nuclease.

Each step in a ChIP experiment must be carefully optimized to maximize signal over background and to achieve high reproducibility. This requires extensive upfront design and optimization of experimental parameters.

How does ChIP-seq work?

ChIP-seq combines the DNA sequencing methods of next generation sequencing (NGS) with chromatin immunoprecipitation. The method detects and sequences genomic DNA fragments that co-precipitate with a given protein of interest, which can be a transcription factor, chromatin remodeling enzyme, or histone mark.

The resulting sequence data can then be analyzed to identify regions of significant enrichment, called peaks. These peaks can then be compared to the DNA sequences in a matched control sample, which may consist of untreated DNA, treated DNA but no antibody, or an anti-control antibody.

To obtain consistent results, several factors must be optimized. For example, the antibody used in the immunoprecipitation must be specific enough to specifically bind to the protein of interest. This can be tested using a variety of methods, including tiling microarrays. ChIP-seq also requires a sufficient number of sequence reads to accurately call peaks, which can be improved by using paired-end sequencing to reduce the effects of sequencing errors and base calling bias.

What are the advantages of ChIP-seq?

One significant advantage of ChIP-seq over microarrays is the ability to generate far more precise mappings of protein-DNA interactions, as well as provide high resolution information on histone modifications and nucleosome positioning. This enhanced spatial resolution is important for profiling post-translational modification of chromatin and for identifying sequence motifs.

Additionally, ChIP-seq provides more flexibility in experimental design as it is not limited by the number of oligonucleotide probe sequences on an array. This is especially helpful for studies involving heterochromatin or repetitive regions that are often obscured by the probes on an array.

The disadvantage of ChIP-seq is the high variability that results from a number of factors, including sequencing depth, bias in DNA base calling and mapping (due to short tag sequences), genomic amplifications and repeats. In order to overcome this, it is essential that the peaks identified in ChIP-seq are compared to the same loci in a control sample. This is typically done by sequencing a mock IP or nonspecific IP DNA library.

What are the disadvantages of ChIP-seq?

Although sequencing technology is rapidly improving, it still has limitations. A major issue is the fact that the sequenced tags are not evenly spread over the genome and the fold enrichment at peaks can be inaccurate due to sampling bias. Therefore, it is important to use a suitable input DNA profile for normalization and make sure that the amount of starting material used is sufficient.

Another problem is that shearing of DNA during the ChIP process can result in non-uniform fragmentation of chromatin, which can lead to uneven distribution of the sequenced tags and masking of repetitive sequences. This can result in the identification of false peaks.

Lastly, different peak-calling software packages have different methods for tag shifting, profile normalization, and the detection of binding sites. This can lead to significant variation in the number and width of the peaks identified. It is important to validate peak calls using quantitative PCR. In addition, the results of ChIP-seq experiments should be replicated on different samples to ensure reproducibility.
