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 …
Metadata is data that provides basic information about other data. It makes tracking and working with specific data easier. For example, a video may include metadata which describes the name of the video, duration of the video, record/release date of the video, genre of the video, category of the video and more. Likewise, there are …
VBR or Variable Bit Rate is a term used in computing and telecommunications that relates to the bitrate used in video or sound encoding. VBR files differ the amount of output data per time segment contrasted with constant bitrate (CBR). While a smaller amount space is allocated to less complex segments, VBR allows a higher …
ABS or Adaptive Bitrate Streaming is a performance management method for streaming multimedia over computer networks.  In the past, most video streaming approaches were built on RTSP or RTP. However, today most adaptive streaming technologies are built for transmission over HTTP over large, broad-distribution networks. With this streaming method, viewers can get optimal image and …
Bitrate describes the rate at which bits are transferred from one point to another. In simple language, it measures how much data is transmitted from one point to another in a given amount of time. Commonly, bitrate is measured in megabits per second (Mbps), kilobits per second (Kbps) or bits per second (bps). Bitrate can describe …
Digital Video Broadcasting (DVB) is a set of globally open standards that define digital broadcasting using existing cable, satellite and terrestrial infrastructures. These standards define the data link layer and physical layer of the distribution system. Similar to all digital communication systems, DVB uses the simple yet powerful binary digit pair i.e. ones and zeros, …
OVP or Online Video Platforms can use a user-generated content (UGC) model, software as a service (SaaS) business model or a do it yourself (DIY) model. OVP offers an end to end solution from creating a website, uploading video, encoding video, video playback to user management for both video on demand and live streaming. Usually, …
