2. Compression artifact - Wikipedia

   en.wikipedia.org/wiki/Compression_artifact

   A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ( streamed ) within the ...

3. Video feedback - Wikipedia

   en.wikipedia.org/wiki/Video_feedback

   Video feedback. Video feedback is the process that starts and continues when a video camera is pointed at its own playback video monitor.The loop delay from camera to display back to camera is at least one video frame time, due to the input and output scanning processes; it can be more if there is more processing in the loop.

4. Noise (video) - Wikipedia

   Noise, static or snow screen captured from a blank VHS tape. Noise, commonly known as static, white noise, static noise, or snow, in analog video, CRTs and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices.

6. Dither - Wikipedia

   en.wikipedia.org/wiki/Dither

   Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of mastering audio to a CD. A common use of dither is converting a grayscale image to black and white , so that the density of black dots in the new image approximates the average gray level in the original.

7. Video - Wikipedia

   en.wikipedia.org/wiki/Video

   Video quality can be measured with formal metrics like peak signal-to-noise ratio (PSNR) or through subjective video quality assessment using expert observation. Many subjective video quality methods are described in the ITU-T recommendation BT.500. One of the standardized methods is the Double Stimulus Impairment Scale (DSIS).

8. Sound quality - Wikipedia

   en.wikipedia.org/wiki/Sound_quality

   Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...

9. Video post-processing - Wikipedia

   en.wikipedia.org/wiki/Video_post-processing

   Video post-processing is the process of changing the perceived quality of a video on playback (done after the decoding process). Image scaling routines such as linear interpolation, bilinear interpolation, or cubic interpolation can for example be performed when increasing the size of images; this involves either subsampling (reducing or shrinking an image) or zooming (enlarging an image).
