The word “Pixel” means a picture element. This is the smallest element of an image. Pixels are generally square or round. Typically, they are arranged in a two-dimensional grid to create an image. Each pixel can be turned on (illuminated) or off (darkened) on a screen (Computer Monitor, Television Screen, Mobile Screen). Resolution of an …
HD (High Definition) video is video of higher resolution and quality compared to SD (Standard Definition). Even though there is no standardized definition for HD, usually any video image with substantially more than 480 horizontal lines is considered high definition. Normally, HD video has a resolution of 1280 x 720p whereas FHD (Full High Definition) …
SD (Standard Definition) video specifies the video and audio codecs and file format that allows users to watch video on several electronic devices built to SD standards. SD video supports different formats, including VC-1, H.264, MPEG-4 and MPEG-2. Standard definition has always been a 4:3 aspect ratio with a resolution of 640 × 480 pixels. …
Embedding allows you to place or copy the video from its original website onto a different site using “embed code” or an html code. To embed a video, copy the embed code from the original video site and paste the code into the site where you would like the video to appear.   Example of …
Resolution is the picture quality displayed on a screen (Desktop, Laptop, Mobile, Tablet, Television Screen). Basically, the resolution is measured by the number of horizontal and vertical pixels. Usually, it is mentioned as width x height, with the units in pixels: for instance, “800 × 600” means the width is 800 pixels and the height …
In video streaming or audio streaming from the Internet, buffering refers to downloading a portion of the data before starting to play the movie or music. Having an advance stream of video frames or audio samples in RAM always avoids interruption if there are temporary delays in transmission while the content is being played. Even there …
H.264 is an industry standard for video compression, the process of converting digital video into a format that takes up less capacity when it is transmitted or stored. H.264 delivers both small file size and high definition quality with half, even quarter of bitrate usage. So far, it is one of the most frequently used …
Bandwidth is well-defined as the volume of data that can be transmitted from one point to another in a fixed amount of time. Usually, the bandwidth is expressed in bytes per second or bits per second(bps) for digital devices. Different bandwidths are required for different applications. For example, standard definition (SD) video (480p) works at …
Generally, aspect ratio is used to determine the proportional relationship between the vertical and horizontal sizes of computer graphics. Aspect ratio is represented by the symbolic notation: X:Y. The values of X and Y are not the real width and height of the image, but describe the proportional relationship between them. For instance, usually movies are …
Codec is the blend of two words i.e. coder and decoder (co + dec). A codec encodes a signal or a data stream for storage and transmission, probably in encrypted form and the decoder function converses the encoding for editing or playback. Codecs are mainly used to compress the large video and audio files to …
