Definition

Video representation, as the name implies, specifies a way of representing a video. While some work refers to video representation as the way to present or express video content through some extracted or summarized content units such as scenes or objects, the majority regard it more as the way the video content is stored. In other words, it is about video format which describes the sequence, structure, and content of frames that create the moving video image, along with any possible audio or text (closed caption) information.

Historical Background

A video can be represented in either analog or digital formats. Typical analog formats include NTSC (National Television System Committee), PAL (Phase Alternating Line), and SECAM (Séquentiel couleur à mémoire, French for “Sequential Color with Memory”) which are commonly used in the domain of commercial broadcast. On the other hand, due to the rapid development of computer technologies, the...
