AVC (H.264)
AVC or Advanced Video Coding (also known as 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. AVC or 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 formats for recording, compression as well as the distribution of video content. Including 4K UHD, it…

Bandwidth
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 1 megabit per second (Mbps), however, high definition (HD) video (720p) works around 4 Mbps, and HDX (1080p), more than 7 Mbps. Primarily, there are…

Aspect Ratio
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 shot with a wide-angle lens, typically have an aspect ratio that is 16:9. That means, the width of the image area is almost double of…

Codec
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 transmit flawlessly over the internet. At the users end the video/audio files are decoded for viewing. Most commonly, codecs are used in streaming media, video…
