These include grids, gradients, solid colours, checkerboards, colour bars and a strobe. Users can also import an image file to use as a custom test pattern. Typical applications for this include event logos and content maps for testing alignment. Animated test patterns always move exactly one pixel per frame, giving perfectly smooth motion and making it very easy to confirm the entire system is providing pixel perfect output. Video freeze and blackout modes are included. S-Series processors feature front panel buttons for enabling/disabling freeze and blackout, for cases when no user interface is connected.

  • BA(Prog)III Yr 14/04/2020 Displays Interlacing and Progressive Scan
    BA(prog)III yr 14/04/2020 Displays • Colored phosphors on a cathode ray tube (CRT) screen glow red, green, or blue when they are energized by an electron beam. • The intensity of the beam varies as it moves across the screen, some colors glow brighter than others. • Finely tuned magnets around the picture tube aim the electrons onto the phosphor screen, while the intensity of the beamis varied according to the video signal. This is why you needed to keep speakers (which have strong magnets in them) away from a CRT screen. • A strong external magnetic field can skew the electron beam to one area of the screen and sometimes caused a permanent blotch that cannot be fixed by degaussing—an electronic process that readjusts the magnets that guide the electrons. • If a computer displays a still image or words onto a CRT for a long time without changing, the phosphors will permanently change, and the image or words can become visible, even when the CRT is powered down. Screen savers were invented to prevent this from happening. • Flat screen displays are all-digital, using either liquid crystal display (LCD) or plasma technologies, and have replaced CRTs for computer use. • Some professional video producers and studios prefer CRTs to flat screen displays, claiming colors are brighter and more accurately reproduced. • Full integration of digital video in cameras and on computers eliminates the analog television form of video, from both the multimedia production and the delivery platform. • If your video camera generates a digital output signal, you can record your video direct-to-disk, where it is ready for editing.

  • Experience DTV Using LCD TV
    Experiencing DTV on the LCD TV What is DTV? DTV stands for Digital Television, the latest standard and the future of television broadcasting. Unlike analog TV, DTV is broadcast digitally to transmit an audio and video signal for movie-like picture quality and surround sound. HDTV, your ticket to movie theater experiences on your home TV set, is a Digital TV (DTV) format. There are many benefits to DTV, as we will explain below. In addition, on February 1st, 2006, Congress passed a law mandating that all analog TV broadcasts must cease on February 17, 2009. At present, many television stations have begun broadcasting programs digitally. Benefits of Digital Television Improved image and sound quality Digital signals are not prone to interference during transmission, resulting in high fidelity signals all the way to the TV set for immaculate colors, incredible image sharpness and great sound. With DTV we can say goodbye to “ghosting” and “snow” on the TV screen and noise from the speakers. In addition, DTV supports high quality picture formats such as HDTV, meaning you will be able to enjoy movie-like programming right in the comfort of your own living room! Interactive programming With analog TV, we could do very little else with our TV programs other than change the channel. DTV provides us with an interactive viewing experience, a good example of which is the ability to order whichever program we please directly through the TV. That was impossible in the analog TV age. DTV Picture Quality Levels There is more than one DTV picture quality level or format.

  • Screen Tearing
    Screen tearing Screen tearing is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw.[1] The artifact occurs when the video feed to the device is not in sync with the display's refresh rate. This can be due to non-matching refresh rates—in which case the tear line moves as the phase difference changes (with speed proportional to difference of frame rates). It can also occur simply from lack of sync between two equal frame rates, in which case the tear line is at a fixed location that corresponds to the phase difference. During video motion, screen tearing creates a torn look as edges of objects (such as a wall or a tree) fail to line up. Tearing can occur with most common display technologies and video cards, and is most noticeable in horizontally-moving visuals, such as in slow camera pans in a movie, or classic side-scrolling video games. Screen tearing is less noticeable when more than two frames finish rendering during the same refresh interval, since this means the screen has several narrower tears instead of a single wider one. A typical video tearing artifact (simulated image) Contents Prevention V-sync Other techniques References Prevention Ways to prevent video tearing depend on the display device and video card technology, software in use, and the nature of the video material. The most common solution is to use multiple buffering. Most systems use multiple buffering and some means of synchronization of display and video memory refresh cycles.

HDTV standardization 6 5. HDTV formats 6 6. Benefits ofH DTV in video surveillance 6 7. Conclusion 7 Introduction The TV market is moving rapidly towards high-definition television, HDTV. This change brings truly re- markable improvements in image quality and color fidelity. HDTV provides up to five times higher resolu- tion and twice the linear resolution compared with traditional, analog TV. Furthermore, HDTV comes with wide screen format and DVD-quality audio. Growth in the consumer market for HDTV is impressive. In 2007 the HDTV household penetration in the U.S. was approximately 35%. According to estimates, 85% of all viewers will have an HDTV set at home by 2012. Already today, virtually all major television productions are HD. The two most important HDTV standards today are SMPTE 296M and SMPTE 274M, which are defined by the Society of Motion Picture and Television Engineers, SMPTE. 1. HDTV impact on video surveillance market This development is now starting to have an impact on the video surveillance market, as customers ask for higher image quality standard. The possibility of clearer, sharper images is a long sought quality in the surveillance industry, i.e. in applications where objects are moving or accurate identification is vital. It can be argued that some of these requirements can be met with megapixel network cameras. How- ever the notion of “megapixel” is not a recognized standard but rather an adaptation of the industry’s best practices and it refers specifically to the number of image sensor elements of the digital camera.
