  2. Video scaler - Wikipedia

    en.wikipedia.org/wiki/Video_scaler

    An enlargement of a small section of a 1024x768 (VESA XGA) resolution image; the individual pixels are more visible in its scaled form than its normal resolution.A video scaler is a system that converts video signals from one display resolution to another; typically, scalers are used to convert a signal from a lower resolution (such as 480p standard definition) to a higher resolution (such as ...

  3. Display resolution standards - Wikipedia

    en.wikipedia.org/wiki/Display_resolution_standards

    Second, the HDTV-standard 1280 × 720 [127] (otherwise commonly described as "720p"), which offers an exact 16:9 aspect ratio with square pixels; naturally, it displays standard 720p HD video material without stretching or letterboxing and 1080i/1080p with a simple 2:3 downscale. This resolution has found some use in tablets and modern, high ...

  4. List of common display resolutions - Wikipedia

    en.wikipedia.org/wiki/List_of_common_display...

    The vertical resolution is usually a multiple of 8 or 16 pixels due to most video codecs processing pixels on such sized blocks. A widescreen FHD video can be 1920 × 800 for a 12∶5 ratio or 1920 × 1040 for roughly 1.85 × 1, for instance.

  5. Uncompressed video - Wikipedia

    en.wikipedia.org/wiki/Uncompressed_video

    Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.

  6. Video super-resolution - Wikipedia

    en.wikipedia.org/wiki/Video_super-resolution

    Video super-resolution (VSR) is the process of generating high-resolution video frames from the given low-resolution video frames. Unlike single-image super-resolution (SISR) , the main goal is not only to restore more fine details while saving coarse ones, but also to preserve motion consistency.

  7. Nvidia PureVideo - Wikipedia

    en.wikipedia.org/wiki/Nvidia_PureVideo

    Nvidia's press material cited hardware acceleration for VC-1 and H.264 video, but these features were not present at launch. Starting with the release of the GeForce 6600, PureVideo added hardware acceleration for VC-1 and H.264 video, though the level of acceleration is limited when benchmarked side by side with MPEG-2 video.

  8. x265 - Wikipedia

    en.wikipedia.org/wiki/X265

    x265 is an encoder for creating digital video streams in the High Efficiency Video Coding (HEVC/H.265) video compression format developed by the Joint Collaborative Team on Video Coding (JCT-VC). [ 4 ] [ 5 ] [ 6 ] It is available as a command-line app or a software library , under the terms of GNU General Public License (GPL) version 2 or later ...

  9. Image scaling - Wikipedia

    en.wikipedia.org/wiki/Image_scaling

    Another solution to the downscale problem of bi-sampling scaling is mipmaps. A mipmap is a prescaled set of downscaled copies. When downscaling, the nearest larger mipmap is used as the origin to ensure no scaling below the useful threshold of bilinear scaling. This algorithm is fast and easy to optimize.
