    Photosensitive Epilepsy in Game And Video

    The friends who play the game all know that the opening of some games will have some introduction and matters needing attention. Most players don’t take much more than a glance at these prompts, as they do when they unthinkingly check the “User Guidelines” box. Just like ghost doesn’t crawl out of the computer screen and eat you.It’s just a game. It’s not life-threatening. Once upon a time, there were many TV viewers who had this idea, and they never knew that patients with a photosensitive disease would have severe epileptic reactions or even life-threatening seizures under certain conditions.It wasn’t until 1997 that a television accident in Japan completely renewed people’s understanding of the disease. 3D Dragon Event On December 16, 1997, at around 6:30 p.m., the First Season of Pokemon , which began airing in the same year and has become hugely popular in Japan, was scheduled to air episode 38, “Computer Warrior 3D Dragon,” on Thursday.It was broadcast on more than 37 television stations in Japan and tuned into 4.6 million households. At the time, this figure reached the highest ratings of the broadcast time period. However, when the video showed that the Pikachu destroyed the missile, some viewers began to have blurred vision, headache, dizziness and nausea, and some viewers even experienced severe symptoms such as epilepsy, blindness, convulsions and loss of consciousness. A total of 685 viewers(most of them children),were reportedly taken to emergency services by ambulance across the country, with more than 150 children later …

    What is S/PDIF

    SPDIF (Sony/Philips Digital Interface) is the abbreviation of SONY, PHILIPS digital audio interface. In terms of transmission, SPDIF is divided into two types of output (SPDIF OUT) and input (SPDIF IN). Most of the sound card chips are able to support SPDIF OUT, but we need to note that not every product will provide a digital interface. There are relatively few sound card chips that support SPDIF IN, such as EMU10K1, YMF-744 and FM801-AU, CMI8738, etc. The typical application of SPDIF IN on a sound card is CD SPDIF, but not every sound card that supports SPDIF IN provides this interface either. In terms of transmission carrier, SPDIF is divided into coaxial and optical fiber two, in fact, they can transmit the same signal, only the carrier is different, the interface and the appearance of the cable also has differences. But the optical signal transmission is a popular trend in the future, its main advantage is that there is no need to consider the interface level and impedance issues, the interface is flexible and more resistant to interference. Transmission of digital sound signals through the SPDIF interface has become a common feature of the new generation of PCI sound cards. In the past, when CD-ROMs played records, music in digital format first had to go through D/A processing inside the optical drive. After being converted into an analog signal, it was transmitted to the sound card via the four-pin analog signal cable that we often use, and then a series …

    DP 2.0 Prospect

    It’s been almost two years since the official announcement of the DisplayPort 2.0 interface protocol (collectively referred to as the DP2.0-equipped protocol below), but there was no information on the launch of related products until recently. According to the Video Electronics Standards Association (VESA), displays equipped with DP2.0 interfaces are being developed, while new products will use new system chips and are expected to debut in the second half of 2021. How powerful is the DP2.0 protocol? According to the design scheme when DP2.0 protocol was released in 19, it has a maximum transmission bandwidth of 80Gbps and a new 128/132b encoding mechanism. Compared to the previous generation DP1.4 protocol, DP2.0 protocol has 3 times higher data bandwidth performance and up to 97% improvement in efficiency. In addition compared to the latest HDMI 2.1 protocol, DP2.0 protocol is also 1.6 times higher transmission bandwidth performance. In addition DP2.0 protocol allows the signal to be carried on the USB4/Thunderbolt 4 interface, although it will be limited by the protocol performance of USB4/Thunderbolt 4, limited to a maximum transmission bandwidth of 40Gbps. The role of DP2.0 protocol With such excellent transmission performance, DP2.0 protocol can output 16K@60Hz (DSC), 10K@60Hz lossless, 4K@240Hz, and dual-screen 8K@120Hz video output on a single screen, while also supporting HDR-10 video features. Of course, game enthusiasts like the dual-screen 4K@144Hz lossless is also not in the picture. In short, the DP2.0 protocol allows for higher display resolutions, faster refresh rates, and support for dynamic HDR functionality, allowing for …

  • What is DLSS

    The whole process of DLSS is Deep Learning Super Sampling. By cooperating with game manufacturers, NVIDIA continuously deep learns in the cloud to optimize the algorithm for a certain game, and then runs on the local graphics card to update the algorithm so as to render the game screen more efficiently. Due to the continuous deep learning in the cloud, after a period of time, the game frame rate will also get higher and higher with the algorithm update. DLSS 2.0 offers three different image quality modes: quality mode, balanced mode, and performance mode. They can control the internal rendering resolution of the game, where the performance mode can achieve up to 4x super resolution, that is, in DLSS 2.0-enabled games you choose 4k resolution, but the graphics card will render at 1080p demand and then convert to 4k resolution through the super sampling algorithm, thus achieving 4k output and not affecting the image quality, even as Nvidia says, ” DLSS 2.0 tuned picture quality is more fine than the previous native picture quality”. So the frame rate can be significantly increased in 4k quality. Most games today are not output directly to the screen after rendering, but require a series of post-processing. For example, anti-aliasing features, including TAA time anti-aliasing, FXAA fast adaptive anti-aliasing, etc.. However, there are problems with these anti-aliasing or other image optimization features, such as causing blurring, incorrect processing of graphic elements, etc. For this type of problem, it is impossible to rely solely on …

  • What is Ray Tracing?

    Ray tracing is a technology that calculates the path of the visual field and finds the reflector and the corresponding light source to simulate the lighting effect. In the real world, when light shines on an object, some of the light is absorbed, some is reflected, and some is seen by the eye, and the presence of the object is recognized when the light reflected from the object and its surroundings is observed by the glasses. And ray tracing is to display the screen “lens” as the human eye, shooting invisible light to surrender the object in the screen, and then calculate whether it can match the light source in the screen, and according to the calculated light brightness of the screen to display. This technology concept was originally proposed in 1969 by IBM employee Arthur Appel prototype, in 1979 by Turner Whitted perfected the specific implementation of the idea and the way. The advent of ray tracing makes it possible to simulate light in the picture without calculating the global light, only need to calculate the part of the eye to view the content and then calculate it, significantly reducing the resources required to render the picture at the same level of light. Before the implementation of real-time ray tracing technology on personal computer graphics cards, games need to simulate light performance to enhance the game’s impact, but the computer’s performance can not support the amount of light computing, game developers have come up with a variety of ways …

  • The difference in game picture quality

    Grass Quality This parameter mainly affects how dense the grass is and the quality of the grass, because the grass itself has a complex model and complex mapping, and the highest grass quality in many games is very performance intensive. Water Quality This option is still a big improvement for the screen, looking at the clear water, people will feel different. The quality of the water surface generally do not consume the core power of GPU, so you can turns a little higher. Reflection quality This mainly affects the reflection of the polished surface, such as the surface of the car, and the water, a variety of glass products. This option is also relatively large for the screen to improve, but also more GPU demanding, the computer is not good to use caution. Shadow Quality The items in the game are shadows, then the shadow quality is used to adjust the shadows, better shadows will also make the game’s picture more layered, but the shadows themselves are more GPU-consuming, especially dynamic shadows, for most people, shadows as long as there is on the line, there is no need to open so high, cause you generally will not pay much attention to the shadows. Shadow style Shadows not only have quality, there is also a style that says, some people like a little sharper shadows, some people like a little softer shadows, shadow style is used to change this. I personally think that the shadows in real life should be on …

  • AO effects

    How to Choose the Best Game Graphics Settings

    Resolution Usually, the higher the resolution of an image, the more pixels it contains and the clearer the image is. The resolution has a very big impact on the quality of the game screen. Generally speaking, you just need to make sure that the resolution is the same as the maximum resolution of your monitor. Ambient Occlusion Ambient Occlusion(AO) is an important part of the game image. Because of the blocking effect around the object, the ambient light can only partially hit the object, forming this kind of screen effect. AO effects intuitively give us players the feeling mainly in the brightness of the screen, the screen without AO effects is a little brighter; and after opening AO effects, the local details of the screen, especially the dark shadows will be more obvious. Anti-aliasing We know that the screen is composed of countless points, then the lines are also composed of countless points, then the curve will inevitably appear pixel protrusion phenomenon, the role of anti-aliasing is to eliminate the jaggedness of the edge of the screen. There are many kinds of anti-aliasing such as MFAA, FXAA, TAA, MSAA they all work differently, so for the performance requirements are also different. Metal, Anisotropic The objects in the game are composed of Metal+Anisotropic, the Metal is the virtual state of an object, is the skeleton of the item, the Anisotropic is to put a colorful painting on his surface, so that the item you can see. Anisotropic and so is the …

    Interfaces that has been adopted by Apple

    Apple’s most representative product, known as iPhone, iPad and MacBook, has went through a long history of evolution which covers the product appearance from the internal components of the product. Their interfaces has also swift for several times in the past few decades from their publications. Lightning Apple’s high-speed multi-functional I/O interface is the new Lightning Dock interface, known as the lightning interface, was released by Apple on September 12, 2012 at the Fountainhead Convention Center in San Francisco. The release of the new interface standard also means that Apple’s 30-pin Dock interface, which has been in use for nine years, will be officially replaced. This connector pin is 8pin, its size is significantly reduced. And there is a huge change, that is, both positive and negative can be used. In other words, as early as the Apple iPhone 5 began to use the Lightning data interface, support for positive and negative plug, and Android users are familiar with the USB-C interface similar. And Android phones equipped with support for positive and negative plug USB Type-C interface, which basically only began to appear in 2014 and became popular in 2015. 30-Pin Dock Apple’s proprietary 30-pin connector was common to most Apple mobile devices (iPhone (1st generation, 3G, 3GS, 4, 4S), 1st through 4th generation iPod Touch, iPad, iPad 2, and iPad 3rd gen) from its introduction with the 3rd generation iPod classic in 2003 until the Lightning connector was released in late 2012. As a result of the popularity of Apple’s iPod and iPhone devices using the connector, a cottage industry was created of third-party …

  • What is Apple MFi Certification

    From the iPhone12 to the future generation of iPhone models, Apple has decided to cancel the additional cable that has been bonded with iPhone. Literally, it means that most of the customer are going to purchase their own cable for their phone that will significantly lift the market of the charging cable and charger. When we are going to talk about accessories of Apple products, MFi certification is the inevitable topic. MFi is the abbreviation of Made for iPhone/iPad/iPod which is initially adopted by Apply in 2005 during which this icon is only used on the iPod. It is said that Apple will charge an extra fee of 10% as the commission of using the MFi icon during the early time of MFi certification. With the introduction of the new product line(iPhone, iPad), MFi gradually become a mature and wide covered certification which spans not only from charging cable and charger but also to the territories of adapter, wired earphone, TWS earphone, wireless charging pad. With the release of lightning interface, Apple has fully updated the internal handshake protocol which strictly confined the normal implement of the third party accessories on Apple devices that any accessories without the MFi certification will be refused by the devices and a popup will be shown to indicate the danger of using unauthorized third party accessories. Reasons of why Apple holds enthusiasm about MFi certification are obvious. From Apple’s self-developed system, to the various hardware and accessories, to the maverick interface. Apple has been …
